ICT- input and output devices
Input devices | Output devices |
|---|---|
Keyboard | Monitor |
Mouse | printer |
Camera | plotter |
Hardware has two categories, internal and external.
Motherboard
Central processing unit (CPU)
Random access memory (RAM)
Read only memory (ROM)
Graphics card
Sound card
Network interface card (NIC)
Internal storage devices (hard disk drive and solid- state drive)
A computer system includes three main parts: hardware, software, and data.
The physical components of a computer system are the hardware.
Computer systems include at least four hardware elements: a microprocessor; memory; input and output devices; and data storage devices.
A microprocessor is a small computer chip. It is the brain of a computer.
It is also called the central processing unit (CPU), or microchip.
Memory is hardware that stores information for instant retrieval and processing.
It can be thought of as a kind of scratch pad.
The computer uses its random access memory (RAM) to hold all the data and instructions required during operations.
An input device is hardware that is used for entering data into a machine, such as a computer.
Input devices include keyboards, computer mice, touchpads, joysticks, and scanners.
An output device is hardware that is used for producing results from a machine.
Output devices include computer monitors, printers, fax machines, and speakers.
There are a variety of devices for storing large amounts of data.
Data storage devices—which include hard drives, CD-ROM drives, and DVD drives—save information for later use.
Software is a computer program that contains a set of instructions that tells a computer what to do.
Software is also referred to as a program or an application.
An operating system is software that controls the operation of a computer and directs the processing of programs.
