Companies such as Dell, Gateway, hp, Asus, and many other companies make hardware for personal computers.309753086868000Personal computers are usually called PC’s. There are two types of PCs: 1) Desktops and 2) Laptops or Notebooks. Desktop PC’s are large and sit on a desk or table. We use desktop PC’s in this class. Laptops (sometimes called Notebooks) are small and portable. 20955002235200051822351854200043046652524125There are five important parts to any PC:Monitor24847556432550051371504381500CPU case with the processor and hard drive220980066992500KeyboardMouse3148330889000Cables-6985231140001560195363855003007995525780MONITOR00MONITOR252222061912500170815056197500The monitor looks like a television set. It contains the screen. Monitors come in different sizes. Today most monitors are flat and take up very little space. 3114675267970SCREEN00SCREEN236220014414500-10795062103003879850803275PROCESSOR00PROCESSOR1346200803275HARD DRIVE00HARD DRIVE29940258318500042545068897500The CPU case is the tower or box you see that is connected to your monitor. CPU stands for Central Processing Unit. The CPU case contains two very important components: the Hard Drive and the Processor. -1701801905000-9652020955000-991870982980433641564897000You cannot see the processor because it is inside your computer. The processor is one of the most important parts of your computer because it where the calculations take place. Intel and AMD are the two companies that make most processors. Many people call the processor the “brains” of the computer. The hard drive is also inside the CPU case. The hard drive is where your software applications are stored. It is also the place where your documents are stored when you save them. You save your work on a hard drive.156146586360000The computer keyboard is the same as a typewriter keyboard. A keyboard contains over 100 different keys. There are keys for letters, numbers and symbols. On some keyboards there is a 10 key- pad for entering numbers and calculations. Can you find the 10-key pad on your keyboard?47625137604504000500The mouse controls the cursor. It is the tool that lets you select text and graphic items displayed on the computer screen. The cursor can appear in different forms depending on the job you are doing. Sometimes the cursor looks like a flashing line. This is called the insertion point – it tells you where you can insert letters and words. Sometimes the cursor looks like a pointer (arrow) and other times it looks like a hand or a cross. Below are three examples of what the cursor can look like.762047371010795988060 Insertion Point for typing your words. Hand that you will see on the internet when you are on a hyperlink. The normal pointer arrow that you will see on the desktop.-211455100-590559017000Cables connect the components of your computer to each other. Cables plug into ports on the monitor, CPU case and keyboard.Ports on the CPU case:-11430014033500387352514600031908754572000Task 1 – Fill In The BlanksIf you want a small computer that you can carry with you, you should buy a ________________.The monitor contains the ___________________.Inside the CPU case is the _________________ and the hard drive.The ___________ ______________ is where you save your work.The mouse controls the _______________________.Many people call the processor the ______________ of the computer.Cables plug into _______________________________ connect the components of your computer together.Task 2 - Label Each of the Following Computer Hardware 20447042887903931920-12701733550293370-854075105537000-9296407023090039179502807334001374775280733400-9296402807334003870325702309001317625702309003822065137477513335001390015Task 3 – Define In Your Own WordsWhat does PC stand for?What type of computer do we use in the classroom?What type of computer can you carry with you?What are five important components of a PC?What does CPU stand for?What are two important hardware components that you find inside the CPU case?What does the processor do?What does the hard drive do?What are cables used for?-18097550482500More Computer HardwareIn addition to the basic hardware devices there are a few others you should know. 458152552451000206692516129000Printer – a printer creates a hard copy (paper copy) of your work on the computer. Speakers – speakers are used to play music and sound55149758445500Microphone – you can record your voice into the computer by using a microphone. 59055001841500Headset – headsets are like speakers but are used on your ears. Some headsets also have a microphone. 3854450482600Flash drive - A flash drive is a device that lets you save your work to a place outside your computer. When you save a file or document on a flash drive you can take it and use it on another computer.Task 4 – Discuss with a PartnerAre there other hardware components that you know of? What are they?___________________________________________________________What hardware components have you used before?___________________________________________________________4857754305300What components do you want to learn how to use better?-29527551435000Input and OutputSome computer components provide information that goes INTO the computer - these are INPUT devices. Some components produce information that comes OUT of the computer – these are OUTPUT devices.
