Question

List the five major components of a computer system.

Short answer

Answer: The five major components of a computer system are: 1. Central Processing Unit (CPU): It is the "brain" of the computer responsible for processing instructions, performing calculations, and managing the flow of data. 2. Memory: It stores data and instructions required for the CPU to perform its tasks. It is divided into primary (RAM) and secondary (hard drive) memory. 3. Input Devices: Hardware components like keyboard, mouse, and touchscreen that enable users to input data and instructions into a computer system. 4. Output Devices: Hardware components like monitors, printers, and speakers that display or output the results of processed data to the user. 5. System Software: It manages and controls the various hardware components in a computer system, including the Operating System (OS) which manages resources and provides a user interface.

Step-by-step solution

1. Central Processing Unit (CPU)

The Central Processing Unit (CPU) is the "brain" of the computer. It is responsible for processing instructions, performing calculations, and managing the flow of data in the computer.

2. Memory

Memory is the component that stores data and instructions required for the CPU to perform its tasks. It is divided into two types: primary (RAM) which stores data temporarily and is volatile, and secondary (hard drive) which stores data permanently and is non-volatile.

3. Input Devices

Input devices are hardware components that enable users to input data and instructions into a computer system. These include devices like keyboard, mouse, and touchscreen.

4. Output Devices

Output devices are hardware components that display or output the results of processed data to the user. Examples of output devices include monitors, printers, and speakers.

5. System Software

System software is a type of program that manages and controls the various hardware components in a computer system, enabling them to work together efficiently. The most important system software is the Operating System (OS), which manages resources and provides a user interface.
