A computer is an electronic system that can accept, store, and process data to produce information. It carries out tasks through programs and has capabilities for repetitive processing, self-operation, and decision making. A computer system consists of hardware, software, and peopleware. The hardware includes the system unit with a CPU and memory, as well as input, storage, and output devices. Software includes programming languages, system software, and application software. People are the most important component and use computers for various purposes.

- 10. MOTHERBOARD
- 11. Central Processing Unit This is the “BRAIN” of a Computer System It is the device that fetches, decodes and executes instructions Transfers data between the memory and other peripheral devices through data bus For Personal/ Micro Computers, this is referred to as the Micro Chip
- 12. M E M O R Y
- 13. INPUT Input device is a unit that is used to get data from the user into the central processing unit.
- 15. INPUT Card Reader Barcode Reader
- 16. STORAGE Data instructions enter main storage and are held until needed to be worked on. Itcan be an auxiliary or backing storage.
- 17. STORAGE Diskette Magnetic Tape
- 18. STORAGE Universal Serial Bus CDs/DVDs Sticks
- 20. OUTPUT Resultsare taken from main storage and fed to an output device. Shows people the processed data- information in a ready-to-use form.
- 21. OUTPUT MONITOR
