2. INPUT

4. HOME Compact Disc (CD) - CDs store information. The CD can then be put into another computer, and the information can be opened and added or used on the second computer. Note: A CD-R or CD-RW can also be used as an OUTPUT device. Camera - most cameras like this are used during live conversations. The camera transmits a picture from one computer to another, or can be used to record a short video. Drawing Tablet - A drawing tablet is similar to a white board, except you use a special pen to write on it and it's connected to the computer. Then the word or image you draw can be saved on the computer. Digital Camera - A digital camera can be used to take pictures. It can be hooked up to a computer to transfer the pictures from the camera to the computer. Some digital cameras hold a floppy disk, and the floppy disk can be taken out of the camera and put directly into the computer. Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications.

5. PROCESS In computing, a process is an instance of a computer program, consisting of one or more threads, that is being sequentially executed by a computer system that has the ability to run several computer programs concurrently.

7. OUTPUT

8. Output is the result of your work. It is the hard copy of your files. You can produce your hard copies through output devices. Output devices are used for displaying or printing the result of execution of a program on the computer. Input devices include mouse, keyboard or a scanner which are used for data or control inputs.

9. HOME Headphones - Headphones give sound output from the computer. They are similar to speakers, except they are worn on the ears so only one person can hear the output at a time. Floppy Disk - A floppy disk is used to record information on. The information is stored on the floppy disk and can be used later or used on another computer. Disk Drives - A disk drive is used to record information from the computer onto a floppy disk or CD. Speaker - A speaker gives you sound output from your computer. Some speakers are built into the computer and some are separate.

10. STORAGE

11. Computer data storage , often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.

12. The Central Processing Unit ( CPU ) or processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. This term has been in use in the computer industry at least since the early 1960s. The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same. HOME
