5 Kinds of Computers (pg 15-16) Different kinds of computers are made for different purposes (e.g. tablets, desktops etc). You need to be able to: - Select the most appropriate type of computer for someone s needs - Select the key features someone needs to consider when wanting a computer for a specific need (e.g. gaming) Types of Computer Fill in the gaps: The physical size of a computer is important for. However, the drawbacks of small tablet computers can be and owing to small and not being able to see so much on the screen. Smaller computers might also be less as they need to maximise life. powerful usability portability buttons screen size battery Rank these computers in order of size (1=smallest, 6 = biggest) Laptop PDA (personal digital assistant) Netbook Desktop Notebook Tablet Match up the word to the definition: PDA Similar to a notebook but typically less powerful. Not designed for high spec games but for internet use and watching videos. They can have a longer battery life than bigger devices partly because of the smaller screen size and less powerful processor. Netbook Small enough to hold in the hand. Typically contains information management type programs such as notepad, calendar, contacts, and diary. Some connect to the web via mobile phone. Notebook These can be as powerful as desktops but are more portable. Typically used on a desk or on the train. Laptop More compact than a laptop. The benefit being it is more compact, but the drawback is that the screen size is smaller, which can be frustrating to some users. Desktop A box, designed for use in one location. Typically more powerful than smaller computers and enables the permanent connection setup of multiple peripheral devices such as music keyboards, mixers, 3d printers etc. You can connect big screens to them. Some can support multiple screens depending on the graphics card(s) installed. They are typically easier to upgrade than laptops. Which type of computer would you recommend for: 1. Using iplayer, Facebook, ebay and occasional online shopping. 2. Doing office work whilst commuting. 3. In a music studio. EXPLAIN YOUR ANSWER.

6 Features of a computer Processor The brain of the computer. Governs how fast the computer can complete calculations measured in gigahertz (GHz). (But not necessarily the overall speed of the computer). Memory (also known as RAM Random Access Memory). This is temporary memory and stores open software and whatever document you are working on. The more memory you have, [1] the more programs you can have open and [2], you can work with bigger documents (e.g. big Photoshop images) whilst maintaining processor speed. Because it s temporary, if the power fails, you can lose unsaved work. Hard Drive Size The primary storage of a computer. It s where software files and data files are stored. Typically measured in GIGABYTES (GB). Solid disks don t have moving parts and therefore quicker than traditional hard disks, but they are presently more expensive when it comes to cost v capacity. However, they are more robust. Wireless Enabled Allows computers to connect to a network (including the Internet). Wireless connections can be less robust than a wired connection. USB Connection Allows you to connect other peripheral devices. 1. STORAGE: e.g. USB memory stick. 2. OUTPUT: e.g. printer. 3. INPUT: e.g. headset, mouse. The more devices you have, the more USB connections you need. Sound Card These can be built in to the mainboard or plugged in. Some support 5.1 surround sound, some support 7.1 surround sound. Some have optical outputs required by some modern amplifiers that can be connected to computers. Graphics Card - These can be built in to the mainboard or plugged in. Any program that does complicated calculations to do with graphics will typically require a good graphics card. The card is typically another computer in itself, but dedicated to processing graphics. They have their own processor and memory. Optical Drive These use lasers to read and write ( burn ) different media discs, e.g. CDs, DVDs and BluRay. Different drives support different media and have different read and write speeds and capabilities. Screen Graphics designers typically use big screens to make their work easier. There are many types of screen. LCD based screens are popular, though they are varied in quality. Some have a fast response time to avoid blurry animation. Some are brighter than others. Some display colours more accurately than others. John would like a computer to play the computer game Need for Speed Rivals. 1. Which 3 features should John make his priority when choosing a PC to play this game? Explain your answer. [4] 2. His house is equipped with a network that supports both wireless and wired connections. For the best performance, which connection type should John use? Explain your answer. [2] Use the web to locate a picture of each of the above features and write out a description of what it is. Go to What s the biggest capacity of SSD (solid state disk) you can buy for 100? What about a normal hard disk? Why do you think tablet PCs use solid state disks? (Consider what can happen if you drop a laptop with a hard disk that has moving parts). Which feature(s) will be most important to someone who is interested in (put an adjective before the name of the feature, e.g. large memory capacity 1) Storing videos 2) Using complex programs 3) Editing large photographs

7 Computers Continued How can you maximise the charge of a battery-powered computer? Use these words to come up with four suggestions. Screen brightness WiFi Disconnect Earphones Peripherals connect to computers and fall under THREE categories. Input, output and storage. Categorise the following with [I]nput, [O]utput or [S]torage: Printer microphone webcam scanner Memory card FUTURE PROOFING: When you buy a computer, it will eventually become out of date. Is it worth future proofing? (paying a premium for the best you can buy now to prevent it from going out of date too quickly). Write down one reason why some people think it is worthwhile. Socialising over the web Instant messaging (IM) is where an example of real-time communication across a network. What would the following use IM for? (A) Family (B) A programmer 1. Why were emoticons invented? ;-) 2. List 3 disadvantages of IM. 3. How can VoIP save people money on phone calls? 4. What do you need for VoIP to work effectively?

Name three benefits of using a VLE, clearly linked to education. Think about multimedia and when students are not at school. USER-GENERATED SITES, e.g. Wikipedia. Just be careful that the information is accurate, up-to-date & un-biased because anyone can add and edit information. Changes to the site can be tracked and articles rolled back to a previous state. Wikipedia encourages users to back up claims with reference to scientific studies. RSS Feeds. Subscribe to RSS (really simple syndication) to never miss out on the latest news! E.g. subscribe to technology newsfeeds on the BBC web site to be notified of the latest articles. PODCASTING: download records and play them back at a time that suits you. E.g. radio show podcasts.
