Question

Draw a block diagram of a computer system with control and data signals. Explain the three parts of a computer systems...​

Answer 1

Answer:

Block Diagram of Computer System :: The Computer system consists of mainly three types that are central processing unit (CPU),Input Devices, and Output Devices.The Central processing unit (CPU) again consists of ALU (Arithmetic Logic Unit) and Control Unit.

Explanation:

3 PARTS OF COMPUTER SYSTEMS ARE

1. INPUT DEVICES- The set of instructions or information is provided to the computer system or PC with the help of input devices such as (keyboard, mouse, scanners, etc). The Instruction or data presented to the computer system is converted into binary form then it is supplied to a computer system for further processing .
2. OUTPUT DEVICES- Output devices of computer produce or generate results with the help of devices or gadgets such as a printer, monitor, etc primarily these instruction or data provided to a computer system is in binary code so to produce or generate the desired output the system has to convert this data into human-readable form, to do so it has to first present the data or instruction to a computer system for further processing or handling. With the help and assistance of output devices, the system is linked or connected with outside world.
3. CPU( Central Processing Unit)-

The Central Processing Unit is also called the brain or heart of a computer. The CPU is nothing but an electronic hardware device which carries or performs out all the operation such as arithmetic and logic operation. Below we have discussed briefly on arithmetic and logical operation..
