The document outlines the components of a computer system, including hardware, software, and liveware, and describes various types of computers. It explains input and output devices, the Central Processing Unit (CPU), and the importance of operating systems like DOS. Additionally, it covers data measurement units, indicating how information is stored in binary format and organized into bits and bytes.

- 11. WHAT IS A COMPUTER ? COMPUTER IS AN ELECTRONIC MACHINE, WHICH GETS DATAAS INPUT, STORES IT, PROCESS ON IT, AND GIVE OUTPUT AS REQUIRED.
- 12. JINESH Types of computers • Super Computer • Mainframe • Minicomputers • Microcomputers
- 13. JINESH Bits & Bytes Information is recorded in computers in the form of binary digits. Popularly known as BITS(BInary digiTS). Binary digits are made up of 0s and 1s. A set of 8 bits is called BYTES. Every character is represented by a byte.
- 14. JINESH Bits & Bytes 8 bits = 1 byte 1024 bytes = 1 kilobyte (1024 kilobytes)2 = 1 megabyte (1024 megabytes)2 = 1 giga byte
