The uses of Spreadsheet Software

A spreadsheet is a software program to create balance sheets, budgets, timesheets and other types of number-based documents.
Spreadsheets provide tools for working with numerical data; you then can display your information in a traditional row-column format, or in a chart. Spreadsheets are usually used by accountants.



Why spreadsheets may need to be converted to alternative file formats?

Spreadsheets may need to be converted to alternative file formats for many purposes (the standard format for saving spreadsheets in excel is the xls format because the file extension is .xls).
Here are some other alternative formats:

HTML (Hyper text mark-up language)
You would save a spreadsheet as HTML if you wanted to include your spreadsheet as part of a webpage. Your spreadsheet can be viewed but not edited in this format.


PDF (Portable Document format)
You would save a spreadsheet as a PDF if you wanted to publish your Spreadsheet online and allow anyone to download and view it (even if they don’t have a copy of Microsoft Office). This format is very widely used and again it can be viewed but not edited by others.


CSV (Comma Separated Values) file
You would save a spreadsheet as a CSV if you wanted to import the spreadsheet data into a database application. This is a text file with the contents of each cell separated by a comma.


TXT file
You would save this if you wanted a plain TXT file.

Bamboo Graphic Tablet - The coolest gadget for design obsessed


Wacom has introduced three new types of graphic tablets Bamboo ConnectBamboo CaptureBamboo Create.


A graphic tablet also known as graphic pad or drawing tablet is a computer input device which lets you draw images and graphics similar with the way you would draw with a pencil on paper.  Actually, the possibilities of using such a awesome gadget are infinite; it's all up to your creativity.  You can trace an image, put your hand signature on anything, send hand written letters or cards to your friends and family (which is cooler than an ordinary typed letter) etc etc.

Bamboo Create is the most complex and offers some extra features compared to the other two - it can be used instead of a mouse and it has got multi-touch but it's also the most expensive.  However, it's really a small price for someone working in web development or design. 

Here it's what Bamboo Create has to offer:
• Bamboo pen and touch tablet
• Bamboo pen
• Spare pen nibs
• Quick Start guide
• Installation CD (includes driver software, interactive tutorial, and user's manual)
• Software DVD (containing Autodesk SketchBook Express, Adobe Photoshop Elements, Corel Painter Essentials, and Nik Color Filters)
• Training Craft DVD using the enclosed software

Here you have a short demonstration for each of these drawing tablets (meant to make you buy one, of course)

What do F keys do

The function keys.  They are one of the "invisible" parts of a computer keyboard.  Not many people know what they do but you will find them valuable once you know what each of them do.

F1
Once pressed, it will usually bring up the Help menu of the program you are working in.  To get the help menu for Windows, you need to press F1 while you can see the desktop.

F2
This can be a very useful short cut for renaming a folder or a file.  It does the same job as right click, rename.  Used in combination with other keys it can:

F3
This is one true gem!  It opens a find menu in any program you might have opened in Windows including web browsers (Internet Explorer, Google Chrome, Mozilla Firefox etc), word processors (Microsoft Word etc), image organisers (Picasa) and more.

F4
It can be used in combination with the Alt key to quickly close the currently opened application and even to shut down Windows

F5
It is the refresh key. In any application you might be working on, this key will help you get the most current version.  It also starts a slideshow in PowerPoint.

F6
In Internet Explorer and Google Chrome pressing F6 moves the cursor to the address bar; a useful short cut for going to a new web page.

F7
Pressing this function key in a word processor will run the grammar and spell check.

F8
During the computer's boot up process, pressing F8 will help you access the Safe mode.  

F9
This does not have a common use.  However, it may be used in some individual programs.  To find out if it is available in the program you are using, bring up the program’s help screen and type in the words function key.

F10
It activates the menu bar of the currently open application.  You can use F10 to highlight the first menu choice, and then use the arrow keys to move around the menus.

F11
This is a useful trick if you want to see more information on your screen.  Pressing F11 will get you to full screen mode.  TO get back to normal view press the key again.

F12
Opens the Save As  menu in Microsoft Word.

Why spreadsheets need to be converted to alternative file formats


There may be times when a work done in Spreadsheet would need to be showed (eg:  posted on the Internet ), shared or used in a database.

In addition to the standard format (xls format) there are a number of alternative formats that can be used for different purposes.  These include:

·              PDF (Portable Document Format).  A PDF file can only be viewed and not edited.  It is ideal if you want to publish your work on the Internet especially because the user can view it even without having Microsoft Office installed.
·              HTML (Hyper Text Markup Language).  Saved in this format the spreadsheet can be included in a web page.  Same as with a PDF format, the file cannot be edited.
·              CSV (Comma Separated Values).  This is a text file with the contents of each cell separated by a comma.  This format can be used to import spreadsheets data into a database application.
·              TXT.  This is a plain text file.
·              XML (EXtensible Markup Language ).  This file format is designed to only carry data and not to display it.  It is very useful if you need to export spreadsheet data to other applications such as a database.

The top 6 most important components of a computer and their purposes


Motherboard: The Motherboards purpose is to accommodate all of the main internal components such as: the CPU, RAM, ROM, Expansion slots, Heat sink/ fan assembly, BIOS chip, chipset and all the embedded wires that interconnect the motherboards components, internal and external connectors and various ports are also placed on the motherboard.






CPU (central Processing Unit): In terms of computing power, the CPU is the most important element of a computer system. CPU’s come in different form factors, each style requiring a particular slot or socket on the motherboard common CPU manufacturers include Intel and AMD. The CPU is a chip contained on a single integrated circuit called the microprocessor. The CPU contains two basic components, a control unit and an Arithmetic/logic Unit (ALU). The main purpose of the CPU is to carry out program instructions. Each Model of Processor has an instruction set, which it executes. The CPU executes the program by processing each piece of data as directing by the program and the instruction set. While the CPU is executing one step of the program, the remaining instructions and the data are stored nearby in a special memory called Cache. There are two major CPU architectures related to instruction sets: Related Instruction Set Computer (RISC) and Complex Instruction Set Computer (CISC).



RAM (Random Access Memory): RAM is the temporary storage for data and program’s that are being accessed by the CPU. RAM is volatile memory, which means that the contents are erased when the computer is powered off. The more RAM in a computer, the more capacity the computer has to hold and process large programs and files. The main purpose of RAM is when programs and data are being used they are stored temporarily so that the processor can access them quickly. This is because the RAM access time is faster which is in nanoseconds compared to the hard disk access time which is in milliseconds.





ROM (Read Only Memory): ROM chips are located on the motherboard. ROM chips contain instructions for booting the computer and loading the operating system. ROM chips retain their contents even when the computer is powered down. The contents cannot be erased, changed or rewritten by normal means. The main purpose of the ROM is to store the basic input/output system (BIOS) that controls the start up, or boot process.






Fans (CPU, Case, and Graphic’s Card): Computer components generate heat. Heat is caused by the flow of current within the components. If the heat is not removed. The computer may run slower. If too much heat builds up, computer components can be damaged. The fan’s purpose is to keep the components cool by increasing the air flow in the computer case which allows more heat to be removed which keeps the component from being damaged from overheating.






Hard Drive: a hard drive is a magnetic storage device that is installed inside the computer. The Hard drive is used as permanent storage for data. The hard drive is often configured as the first drive in the boot sequence. The storage capacity of a hard drive is measured in billions of bytes, or gigabytes. The speed of a hard drive is measured in revolutions per minute (RPM). A Hard disk is a non volatile storage device, which uses a magnetic disk to store a large amount data i.e. the operating system and applications. The main purpose of hard disk drive is to maintain all of the data, which is stored on it, even when this device is not powered.

League Of Legends

I am reviewing League Of Legends and that is what I think about the game.

Before we deal with the game itself, I’d just like to point out that the natural acronym for this title is LoL. I can’t tell whether I should congratulate the game on that accomplishment, or ridicule it.

So League of Legends is the next evolutionary step for the Defence of the Ancients mod, colloquially known as DotA. Back in the Warcraft 3 days, DotA was nearly the only thing about Warcraft 3 that I actually liked. It felt like the game made that Warcraft 3 really wanted to be at all times, instead of the inconsistent mash-up of action, RPG, and RTS that it really was.

If you are unfamiliar with DotA, let me sum it up: you command a hero unit in the midst of a war. Friendly and enemy (and even some random wild card) troops stream at each other across the battlefield, generally grinding into one another with little more than casualties to show for it. As the hero, you need to intercede in key places, kill enemy troops, gain experience, level up, get beefier, and eventually guide your side to victory over the enemy team. It takes the base and resource management out of Warcraft 3, leaving you free to concentrate on micro-managing one bad-ass guy. And it worked out pretty well.

League of Legends duplicates the same basic gameplay, but expands upon it considerably. First up is the Summoner – that’s you. You have your own separate experience value, gain your own abilities, and have your own stats to track. Your summoner is the only persistent element to the gameplay, as your hero is selected fresh at the start of every match, and always begins at the lowest level. As you level up and gain ‘influence,’ you gain access to more champions and special abilities. You also start earning abilities in three trees of masteries – basically special skills and abilities for your summoner.

I will give this game 7/10 because it’s very fun to play alone and with your friends.

Modern Warfare 3 - Updates





The latest news on Modern Warfare 3
As all Call Of Duty fans know Modern warfare 3 was annouced to be release on 8th November 


Reviews
Modern warfare 3 is an updated version of Modern warfare 2. The graphics look better the game-play is, they actually sound like real life guns. This will be written down in history. The campaign is 'awesome' two powerful people die from Modern Warfare 2 and this ends the war of Modern warfare. they also introduced a co-op survival mode, which can help new Call of Duty players and experienced player can studies the map, is other words unlimited waves of enemy as the wave progress they get harder, competition all around the for the online rank leader board. the multiply however is a different story its a whole new experience for every call of Duty fan. Infinity have introduced weapon proficiency and new perks for the people who don't know what weapon proficiency is, its another way to improve your gun and make it suit how you want it. E.g AK47 has a lot of kick when shooting, but when using a weapon proficiency like kick can reduce the kick for certain gun. Certain gun genre have similar and different proficiency, Sub machine gun have Range this allow you to have a wider range when shooting with an SMG, Light machine guns have speed this allow them to run faster when carrying this certain gun. they also have strike packages 


 REVEAL TRAILER
The reveal was the most exciting trailer made all COD fans were waiting for this moment, this was an great campaign single player    


         


E3 2011 GAME-PLAY
The demo starts off just like most of the Call of Duty series with the player being slowly brought into battle, they warm you up on the first level and get you ready for the good stuff. Although we all love COD it is much the same with very similar voice commands such as “hit it” for explosives and things of that nature. Running, explosives and more as you make your way out of a battleship. More to come



SURVIVAL MODE REVEAL TRAILER
The trailer offers up no new information about the wave-based defence mode - which features explosive-strapped attack dogs, juggernaut invasions, and the ability to buy perks and upgrades with money earned by killing foes - but allows for the first public glimpse of the mode and some of its maps.



REDEMPTION TRAILER
Titled “Redemption”, this trailer shows off more of MW3′s single player storyline, with all of it’s explosions and eye popping visuals. People are already sold on the mulitplayer so why not show the people what makes the single player so strong.

STRIKE PACKAGES
A new behind-the-scenes video for Call of Duty: Modern Warfare 3 has revealed a new system which should dramatically shake up the game's tried-and-true multiplayer component: Strike Packages. These break the player base down into three classes: Assault, which earns the standard set of offensive killstreaks; Support, which unlocks less offensive killstreaks (like UAVs and turrets), but doesn't have their streak reset upon death; and Specialist, which earns no killstreaks, but unlocks additional Perks every two consecutive kills.

OFFICIAL LAUNCH TRAILER
Infinity Ward and Activision have just released Modern Warfare 3's launch trailer. Call of Duty launch trailers have usually been shown for the first time during the first week of November, but this sudden release comes as no surprise since MW3's biggest competitor, Battlefield 3, is being released early next week.


WEAPON PROGRESSION
Modern Warfare 3 Weapons Trailer of the Day: The Call of Duty: Modern Warfare 3 team has released a new trailer showing off the game’s various weapons, and the new ways you customize them.
MW3 introduces a weapon proficiency system that lets you level up your favorite weapons as you use them. Leveling brings perks like reduced kick, reduced sway and extra attachments. The available proficiencies vary by class.
Modes and match customization
Activision released a brand-new Modern Warfare 3 ‘New Modes & Match Customization’ multiplayer trailer today. In the trailer Sledgehammer Games’ Micheal Condrey and Infinity Ward’s Mark Rubin give you another insight in to the multiplayer portion of Modern Warfare 3 including a first look at one of the new game modes, Team Defender, which is a variant of Capture the Flag.
The video also explains how private matches have been significantly enhanced to allow players to create new, fully customizable game modes and share those newly created game modes with friends and the community. Plus, there’s a good look at some of Modern Warfare 3′s new maps as the pair describe how they have been made to flow and feel better. Check out the video below.
The latest trailer for Call of Duty: Modern Warfare 3 has arrived and it is a live action trailer featuring Sam Worthington, Jonah Hill, and a short cameo by Dwight Howard.
I think this trailer does a great job of depicting a natural transition for every gamer in their Call of Duty career. You typically start off as a noob that’s just being happy to run around careless shooting stuff. Then eventually growing up and playing strategically.

The hardened edition of the modern warfare 3 with a steel case a journal and a one year Call of Duty Elite membership.

A perfect example of a gameplay by a famous you-tuber a great example of what you can produce in this great game, this can persuade people to buy this game . (40-3).

Desktops and Laptops


Desktops

 There is a huge difference between a desktop computer and a laptop. The differences are that a desktop is only used in one place it can be at home or if you are working in an office, it also doesn’t need to be recharged because it is connected to the power mains. A desktop also has lots of spare parts that are needed to be connected to the computer like e.g. the main unit which stores all the data that you have in it, the monitor is the screen which allows the person to see all the data, the keyboard which allows putting input information on the screen such as, text, the mouse which allows to move the cursor on the screen and click on the data that you want.




Laptops

A laptop and a desktop are nearly the same in all functions, but the laptops are much smaller and can be taken out any where you go. Laptops unlike the desktop it needs to be charged using a charger and it also has a smaller memory than the desktop; all of the spare parts in the laptop such as the keyboard, the mouse, the speakers and the monitor screen are already built in so there is no need of cable.

HTC

HTC was founded in 1997 by Cher Wang, HT Cho, and Peter Chou. Initially a manufacturer of notebook computers, HTC began designing some of the world's first touch and wireless hand-held devices in 1998.  The company has a rich heritage of many "firsts", including creating the first Microsoft-powered smartphone (2002) and the first Microsoft 3G phone (2005). Their first major product was made in 2000 and was one of the world's first touch screen smartphones. The HTC Dream (also marketed as the T-Mobile G1). It was first released in the United States for pre-order through T-Mobile USA on September 23, 2008, and became available in U.S. T-Mobile stores on October 22, 2008. The G1 was available in the UK several days after its USA launch, and has since been introduced in many countries including Australia and Singapore. In 2009, the company launched the HTC Sense interface for the platform with the HTC Hero.

HTC Dream 



In March 2010, Apple Inc. filed a complaint with the US International Trade Commission claiming infringement of 20 of its patents covering aspects of the iPhone user interface and hardware. HTC disagreed with Apple's actions and reiterated its commitment to creating innovative smartphones. HTC also filed a complaint against Apple for infringing on five of its patients an d sought to ban Apple products imported into the US from manufacturing facilities in Asia. Apple expanded its original complaint by adding two more patents.

HTC Wildfire





In June 2010, the company launched the HTC Evo 4G, the first 4G-capable phone in the United States. In July 2010, HTC announced it would begin selling smartphones in China under its own brand name in a partnership with China Mobile. In 2010, HTC sold over 24.6 million handsets, up 111% over 2009.

HTC was named the "Device Manufacturer of the Year" for 2011 by the GSMA at the Mobile World Congress on 16 February 2011. In April 2011, the company's market value surpassed that of Nokia to become the third largest smartphone maker in the world, behind only Apple and Samsung.
On July 6, 2011 it was announced that HTC would buy VIA Technologies' stake in S3 Graphics, thus becoming the majority owner of S3. On August 6 2011, HTC acquired Dashwire for $18.5M. In August 2011, HTC confirmed that HTC will be entering a strategic partnership with Beats Electronics by acquiring 51 percent of Beat's shares.

In the 2011 Best Global Brands rankings released by Interbrand, HTC was listed at #98 and valued at $3.6 billion.

Based on researcher Canalys, in Q3 2011 HTC Corporation became the largest smartphone vendor in the U.S. by 24 percent, ahead of Samsung's 21 percent, Apple by 20 percent and Blackberry just 9 percent. HTC Corporation made different models for each operator

The Benefits of being on Facebook

Too much Facebook could leave your eyes like this...
Facebook is a social networking website founded by Mark Zuckerberg. This website allows you to stay in touch with either friends or family. Facebook has functions which allow you to chat with friends, video conversations with people and you can play games too online. You can post statuses, video or blogs.

Here are some advantages of being on Facebook

  1. Facebook provides us the chance to choose what you desire to share, and what you don’t need to impart, and what you desire to impart with chosen associates. It also gives us a chance to ‘Like’ certain posts people post on Facebook.
  2. It gives you the chance to add people you know or decline other people you do not know or speak to. And also you can inbox un-added friends. 
  3. It has an installed chat where you can keep in touch with your friends or either the ladies.
  4. You can link certain social-networking websites as well, like Twitter, Formspring, Myspace etc. 
Or.. 
LOOOOOOOOOOOOOOOOOOOL!

NEW PSP VITA



The new PlayStation Vita will be released In February 2012 with two different versions: one with 3G support, and a cheaper version without 3G support.


Notebooks!


Notebooks




Notebooks are small, low-power laptops that cost around £200 - £350. 


They have a built in keyboard and mouse pad where you can use your fingers has the mouse.


The notebook has really good storage space with you being able to get 100 - 250 GB and only 2GB memory which is good for such a small computer system. It is also good for doing work on with up to nine hours of battery life before you have to charge it.

The screen size is roughly around 12 inches, you can use windows 7 on notebooks which is really good thing, the notebooks are good for being able to complete or do work that you need to do, It also has a built in webcam but does not have a built in cd/DVD player. 


The notebook is great if you like working from the sofa, or if you are at work or even on the move it is great to use because your able to work from anywhere in the world.

Memory (RAM)


In a computer system the main memory is RAM, which is electronic memory made up of semiconductor chips, (random access memory), this enables the data stored in memory can be accessed equally quickly.

As a RAM has no moving parts, this enables it to be very fast, working at the speed of electricity.  When a computer is running, it is used to hold programs and data, frequently when it is copying them from a hard disk. If the power goes the data inside the RAM is lost, as a result it needs to be stored on either a hard disk or other storage before switching off the computer.

In a RAM the main property is capacity, which is the amount of data that can be stored. This is measured in either megabytes (MB) or gigabytes (GB). When a computer system is switched on, this is the capacity of bytes that it can hold in memory.

Below is a picture of RAM, which is used inside the computer system to hold programs and data:

Monitors

There are two types of output monitors which are Cathode Ray Tube (CRT) and Liquid Crystal Display (LCD).


The previous monitor is the CRT which is large, bulky and with a glass screen, this makes them robust and hard to damage. They produce a lot of heat when there are a lot of them in a room and it is very noisy.

Nowadays we use LCD screen which are slim, creates less heat, less noise and they are commonly used with desktops, handheld systems and laptops. On the other hand, there are some disadvantages such as, easily damaged, leaves a permanent mark and when looking at it from a certain angle it is hard to see the screen.

Below are some examples of the two types of screens:


CRT









           LCD
                                                        

Computer Components and their Purposes

Computers come with tower cases all different sizes (known as form factors). The size and shape of the case depends by the form factor of the motherboard since it’s the largest component of most computers. Inside these tower cases is where you’ll find most of the components of a computer.

Computers are made of the following components:
Power Supply – Supplies power to the computer

Motherboard - This is where the core components of your computer reside, which are listed below. Also the support cards for video, sound, networking and more are mounted into this board.
  • Processor - This is the brain of your computer. It performs commands, instructions and controls the operation of the computer.
  • Memory - The RAM in your system is mounted on the motherboard. This is memory that must be powered on to keep its contents. Without this the computer will not be able to function.
  • Drive controllers - The drive controllers control the interface of your system to your hard drives. The controllers let your hard drives work by controlling their operation. On most systems, they are included on the motherboard; however you may add additional controllers for faster or other types of drives.
Hard Drive(s) - This is where your files are permanently stored on your computer. Also, normally, your operating system is installed here.

Optical disk drives- Optical drives retrieve and stores data on optical discs like CDs, DVDs, and BDs (Blu-ray discs).

Monitor - This device which operates like a TV set lets the user see how the computer is responding to their commands.

Keyboard - This is where the user enters text commands into the computer.

Mouse - A point and click interface for entering commands which works well in graphical environments. 

Cooling Fan - The cooling fan is usually inside or attached to the tower case. It is there so that the components in the computer don’t overheat and are kept within a specified temperature.

Saint Row: The Third Out now



Introduction 

Saints Row 3 is still in the third person action and driving sequence, now you have worked your way up the rank and you are seen as a celebrity in the series and playing as the leader of the Saints. In the city of Steelport you are able to roam around, playing the main missions as you progress throughout the game, along with side missions. 


I would rate this 5/5 because the mission are challenging, so it give you something to work on.

Over the top

The game is said to be one of the most over the top games of it series, from explosions to kicking anyone in places where you would not think you could do in a game, to absolutely going to the extreme. 


I would rate this 5/5 for the over the top moves and explosions because, it does exactly what the title says and a bit more.

New Features

New features in the game are being able to smash pedestrians to pieces using your fist, dancing in the middle of the street with other pedestrians and posing. You are able to lock on a target more precisely than before because, they have replaced the rubbish pistols which we started with at the beginning of the previous series and the weapons have been improved which looks really good. I think it is about time they made the game a little more interesting. 

I would rate this 5/5 because some of the new features such as, dancing in the street and posing are quite humorous. 

Previous Saint's Row games and Saint’s Row 3

When you successfully complete a mission, you can earn for the character money, weapons, cars, customising your own character and gang respect. The previous Saints Row games used the respect made to play main missions within the game and the Third uses experiences points to spend it on improving the characters such as, their fighting and firearms skills. Introduced into the game is a levelling up system, so every time they level up their characters the player selects their reward. 

Money can be used to either purchase clothing items, weapons and cars, or upgrade their weapons and cars. The money is also used to upgrade the Saints gang, customising their appearance, outfits, and headquarters. In the Third, players can use the Initiation Station system that allows them to upload their characters on The Third’s online community, and are able to download other user’s creations to use with their save-game. There are up to four different appearance styles for their gang, players can choose from. Money is used to purchase shops and other properties in Steelport, this turns into income for the gang.


Overall I would rate this game 8.5/10, because although I love this game, it has some downfalls such as, it takes long to give you a checkpoint, you are unable to pick up the telephone boxes and steal the money as before in Saint’s Row 2.

History of The Internet

The History Of The Internet


The Internet was the result of some visionary thinking by people in the early 1960s who saw great potential value in allowing computers to share information on research and development in scientific and military fields. J.C.R. Licklider of MIT, first proposed a global network of computers in 1962, and moved over to the Defense Advanced Research Projects Agency (DARPA) in late 1962 to head the work to develop it. Leonard Kleinrock of MIT and later UCLA developed the theory of packet switching, which was to form the basis of Internet connections. Lawrence Roberts of MIT connected a Massachusetts computer with a California computer in 1965 over dial-up telephone lines. It showed the feasibility of wide area networking, but also showed that the telephone line's circuit switching was inadequate. Kleinrock's packet switching theory was confirmed. Roberts moved over to DARPA in 1966 and developed his plan for ARPANET. These visionaries and many more left unnamed here are the real founders of the Internet
.
The Internet, then known as ARPANET, was brought online in 1969 under a contract let by the renamed Advanced Research Projects Agency (ARPA) which initially connected four major computers at universities in the southwestern US (UCLA, Stanford Research Institute, UCSB, and the University of Utah). The contract was carried out by BBN of Cambridge, MA under Bob Kahn and went online in December 1969. By June 1970, MIT, Harvard, BBN, and Systems Development Corp (SDC) in Santa Monica, Cal. were added. By January 1971, Stanford, MIT's Lincoln Labs, Carnegie-Mellon, and Case-Western Reserve U were added. In months to come, NASA/Ames, Mitre, Burroughs, RAND, and the U of Illinois plugged in. After that, there were far too many to keep listing here.

The Internet was designed in part to provide a communications network that would work even if some of the sites were destroyed by nuclear attack. If the most direct route was not available, routers would direct traffic around the network via alternate routes.
The early Internet was used by computer experts, engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.

As the Internet has become ubiquitous, faster, and increasingly accessible to non-technical communities, social networking and collaborative services have grown rapidly, enabling people to communicate and share interests in many more ways. Sites like Facebook, Twitter, Linked-In, YouTube, Flickr, Second Life, delicious, blogs, wikis, and many more let people of all ages rapidly share their interests of the moment with others everywhere.
Here’s a little video showing  bit of explanation about the history of the internet:

What I think is better. PC or Laptops?

There have been arguments (silly ones at that) back in the day of the laptop where people would argue about which is better like in some childish way with the console wars “XBOX360! Nah PS3”. And it was quite silly because a laptop and a PC were basically meant for two different things.

- A Laptop was meant for a “get-to-go” PC kind of thing. Where you could put your laptop under your arm and carry it to the park or a nice cafe to study, work or just do what you want. But outside mainly.              
                                                                                       
 Just that it had serious problems that you just couldn’t be asked with so it was no point carrying it outside. The laptops had a very weak and easy-drainable battery if not plugged in to some power source. It charges out quickly if you’re having a tea break outside and playing a video game or just watching a film. And then back home to charge! It also had the point of attracting some visitors late at night if you’re carrying your laptop back, yikes!
Obviously it is simple to carry, not that heavy and actually good to have in a university or almost necessary to be honest. But while being compared foolishly to a PC/Desktop it would surely lose. With its small stature you cannot fit as many powerful and space-taking parts from a PC to a Laptop. Sure you can upgrade your Laptop but it will cost you. Buy a laptop then buy upgrades? Or buy a Gaming Pc or whatever and sit tight with one buy. The PC will always have that advantage.
Comparing a PS3 towards a PSP is basically the same thing. A PSP is the smaller a much smaller version of a ps3. Less power and graphical content. But easy to take like a wallet in a pocket!              
                                                                                                         
You cannot simply compare two different meant for things because there won’t be an equal power “clash”.  One thing will be at a disadvantage and will surely lose because it wasn’t meant for it to be compared towards a prior thing that people use and overtake it. Also worth to mention that if you buy a really good laptop or upgrade it that laptop will take over some old PC or normal ones. But also what their good for is their price because if you don’t have enough for a good PC you can buy a good laptop. In my opinion it’s simple. Looking for a strong PC that can play games, play movies and have good space? Buy a Good PC. If you’re looking for something cheaper but also want something that’s not far behind. Buy a good laptop.
It all comes down to what you need. What could be more valuable for work and such.

One of The Input Devices That We Use On Different Computer Systems

                               Webcam

 There are many different types of webcams that you are able to use.

A webcam is a small video camera that you can use on desktop computers and many different computer systems, the webcam feeds live images to a computer or computer network, this is a device where you can connect the usb into the computer and are able to use the webcam on many different types of Application software that is on the computer itself.

You can use the webcam to have a video call with people, this means that you can talk to someone and see their faces without being in the same house or country.

It is mostly used in by bosses in companies to talk to their employees without having to be in the same room this is also used by many different military forces who use small webcams so the soldiers on the front line can show whoever is in charge what is going on while the soldiers are on the front line while the person in charge is safely at the base. 

You can take live images from your webcam and save them on your computer and upload them onto websites like facebook, twitter, blogger and many more websites over the internet, you can also upload pictures onto windows live messenger ( MSN)

And on some laptops and notebooks they have built in webcams.


Halo

Halo: Combat Evolved, is a first-person shooter video game developed by a gaming company called Bungie and published by Microsoft Game Studios. This game is usually played on xbox and other consoles but I prefer to play it on PC because it is better and you can play live with other people. You can only do this in  a trial version they released on a later date. I mostly play this game at my college (And it works) because of the type of connections Halo offers you a chance to pick a type of connection you want to play live against people.


An internet connection allows you to play with your friends but other people across the world can join and LAN does the same thing but the connection is private so anybody registered with the same network can join but worldwide people can’t. Here some.

 Here some pictures of the trial version below...




Computer Types

 Computer Types
Desktop computers are probably the type of computer you are most familiar with. They come with a monitor (now usually a TFT screen), keyboard, mouse, CD-RW and a DVD-RW or at least a DVD-ROM.






Laptop computers are also very common. They are usually have the same processors as desktops and similar sized main memory and hard disk drive although you will pay more for a laptop as a desktop with the same specification. Laptops have the advantage that they can carried about easily and run from a battery.

Often they have built in wireless technology allowing them to connected to network without having to use cables. Laptops do not come with a mouse due to the fact that they are often used where there in not a table to use a mouse on. Instead they have a touchpad built into them. You would also expect a laptop to have a CD-RW and DVD-ROM as standard.

Palmtop computers (sometimes called PDAs (Personal Digital Assistants)) have a small touch sensitive screen and come with a stylus allowing the user to select things off screen. Data entry is usually done using handwriting recognition although some PDAs do have a small keyboard.

They can be used to do tasks similar to ones done by desktop and laptops but more often they are used for note taking, calendars, address books and a means of sending and receiving email. A palmtop works together with a desktop or laptop so data can be transferred between computers. This is done using a cable or using Bluetooth wireless technology.

Mainframe computers are very large powerful computer systems that are usually at the heart of a business. The mainframe computer will have a very powerful processor, large amounts of main memory and a huge backing storage capacity.

They are accessed through one or more terminals. Terminals consist of a screen, keyboard, mouse but no processor as all the processing is done by the mainframe.

Here’s a little video to show you the types of computers
