Fundamentals of Computer - Question Answer Format (8 Marks)
Q1: What is a Computer? Explain its basic functions.
A computer is an electronic device that accepts data as input, processes it, and gives meaningful
output. The basic functions of a computer are:
1. Input: Accepting data through input devices like keyboard, mouse.
2. Processing: Performing operations on data using CPU.
3. Storage: Saving data permanently or temporarily (Hard Disk/RAM).
4. Output: Displaying the result using output devices like monitor, printer.
5. Control: Managing the execution of instructions.
Q2: Explain the different types of computers.
Computers can be classified based on size and purpose:
1. Microcomputer: Used at home and offices, e.g. desktops, laptops.
2. Minicomputer: Used in small businesses.
3. Mainframe: Large computers used by big organizations.
4. Supercomputer: Extremely powerful used for research and complex calculations.
5. Embedded computers: Found in devices like washing machines, mobiles.
Q3: What are the basic components of a computer system?
The basic components are:
1. Input Unit: Devices like keyboard, mouse.
2. Output Unit: Devices like monitor, printer.
3. Central Processing Unit (CPU): Brain of the computer, consists of:
- Arithmetic Logic Unit (ALU)
- Control Unit (CU)
4. Memory/Storage Unit: RAM, ROM, Hard Disk, etc.
