Key points
- Identify and differentiate between computer hardware and software.
- Understand the function of key hardware components (CPU, RAM, Storage).
- Recognize common input and output devices.
- Explain the basic role of an operating system.
Common exam trap
Confusing hardware and software.
Definitions
- Term
Hardware
- Meaning
The physical components of a computer system that can be touched, such as the monitor, keyboard, CPU, and mouse.
- Term
Software
- Meaning
A set of instructions, data, or programs used to operate computers and execute specific tasks.
- Term
CPU (Central Processing Unit)
- Meaning
The primary component of a computer that performs most of the processing; it is often referred to as the 'brain' of the computer.
- Term
RAM (Random Access Memory)
- Meaning
A type of computer memory that can be read and changed in any order, typically used to store working data and machine code currently in use. It is volatile memory.
- Term

A type of non-volatile memory used in computers and other electronic devices. Data in ROM cannot be electronically modified after the manufacture of the memory chip. It typically stores firmware.
- Term
Operating System (OS)
- Meaning
System software that manages computer hardware, software resources, and provides common services for computer programs.
- Term
Binary System
- Meaning
A number system that uses only two symbols, typically 0 and 1, to represent all numbers. This is the fundamental language of computers.
