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) - the "brain" of the computer, responsible for processing and managing all data and tasks within the system. 2. Memory - includes both volatile (RAM) and non-volatile (ROM) memory types, crucial for the computer's functioning. 3. Input/Output Devices - components such as keyboards, mice, monitors, and printers that allow the computer to interact with the external environment. 4. Storage Devices - hard drives, SSDs, and optical drives used for long-term storage of data and programs. 5. Motherboard - the central hub connecting all other components, responsible for communication pathways, power distribution, and overall functioning regulation.

Step-by-step solution

1. Central Processing Unit (CPU)

The Central Processing Unit (CPU) is considered the "brain" of the computer as it carries out the instructions of a program. It is responsible for processing and managing all data and tasks inside the computer system.

2. Memory

Memory encompasses two types: Random Access Memory (RAM) and Read-Only Memory (ROM). RAM is a type of volatile memory that means it stores data temporarily while the computer is on and gets erased when the system is turned off. ROM, on the other hand, is a type of non-volatile memory that means it retains data even when the system is turned off. Both these types of memory are essential for the computer to function.

3. Input/Output Devices

Input/Output (I/O) devices are components that allow the computer to interact with the external environment. Input devices like a keyboard, mouse, scanner, and microphone are used to provide data to the computer. Output devices such as monitors, printers, and speakers display, print or produce information, allowing users to communicate and interact with the computer system.

4. Storage Devices

Storage devices, such as hard drives, solid-state drives (SSDs), and optical drives, are used to store and retrieve data in a computer system. These devices provide long-term storage for data and programs, ensuring they are available even when the computer is turned off.

5. Motherboard

The motherboard, also known as the mainboard or system board, is the central hub that connects and supports all the other components of a computer system. It provides communication pathways for data transfer between the CPU, memory, storage devices, and input/output devices. A computer's motherboard also facilitates power distribution and helps regulate the overall functioning of the system.
