Explain the role of the CPU in a computer system.

The CPU is responsible for performing calculations and processing on the input data to generate the output. It executes instructions, performs arithmetic and logic operations, and controls the operation of the entire computer system. Signup and view all the answers

What is the primary function of the memory unit in a computer system?

The memory unit is used to store data, instructions, and output information temporarily during processing. It consists of primary memory (RAM) and secondary storage devices like hard disk drives and solid-state drives. Signup and view all the answers

How do primary memory (RAM) and secondary storage devices differ in their usage?

Primary memory (RAM) is used to store data and instructions that are currently being processed, while secondary storage devices are used for long-term storage of data and programs. Signup and view all the answers

Explain the process of data processing in a computer system involving the input unit, CPU, and memory unit.

When a user inputs data through the input unit, it is temporarily stored in the memory unit. The CPU then performs calculations and processing on the input data to generate the output, using the memory unit to store temporary data and instructions during processing. Signup and view all the answers
