Answers
Answer:
Explanation:
All types of computer systems need to perform four main tasks: input, store, and process data, and output the results. To perform these tasks, computer systems organise their hardware so that internal and external parts can communicate and co-ordinate with each other.
The internal components of a computer system consist of the hardware required to store and process data, and communicate with external devices, such as the input (e.g. keyboard, mouse), output (e.g. screen, printer), and external storage devices (e.g. USB stick). External devices that are portable are also called peripheral devices or peripherals.
The main internal components of a computer system are:
Processor
Main memory
Input/output (I/O) controllers
Buses: Address bus, data bus, and control bus
Other types of memory — processor registers, cache, and virtual memory — are also crucial for the operation of a computer system. Secondary storage (e.g. SSD, HDD) is a component of a computer system where data and instructions can be read from and written to permanently. Secondary storage is discussed further in the Hardware topic.
