Computer Hardware

Computer hardware (pronunciation: /kəmˈpjuː.tər ˈhɑːrd.weər/) refers to the physical components that make up a computer system. The term is derived from the English words "computer", which comes from the Latin computare meaning "to calculate", and "hardware", which has its origins in the old English hordweard, meaning "one who guards treasure".

Computer hardware is divided into two main categories: CPU and peripherals. The CPU, also known as the "brain" of the computer, carries out most of the processing inside computers. Peripherals include input devices like the keyboard and mouse, output devices such as the monitor and printer, and storage devices such as hard drives and SSDs.

Components of Computer Hardware

Central Processing Unit

The CPU (pronunciation: /ˌsiː.piːˈjuː/) is the primary component of a computer that performs most of the processing inside the computer. It interprets and carries out the basic instructions that drive a computer.

Peripheral Devices

Peripheral devices (pronunciation: /pəˈrɪf.ər.əl dɪˈvaɪs/) are devices that are connected to a computer but are not part of the core computer architecture. They include input devices, output devices, and storage devices.

Input Devices

Input devices (pronunciation: /ˈɪn.pʊt dɪˈvaɪs/) are hardware devices that send data to the computer. Examples include the keyboard and mouse.

Output Devices

Output devices (pronunciation: /ˈaʊt.pʊt dɪˈvaɪs/) are hardware devices that receive data from the computer. Examples include the monitor and printer.

Storage Devices

Storage devices (pronunciation: /ˈstɔːr.ɪdʒ dɪˈvaɪs/) are hardware devices that are used to store data. Examples include hard drives and SSDs.
