A computer is an electronic device that can accept input data, process data, store data, and produce output according to instructions. It consists of input devices like keyboards and mice to enter data, output devices like monitors to display or print output, a central processing unit to perform calculations and control functions, and storage devices like hard drives and memory to permanently or temporarily hold data. Charles Babbage is considered the father of modern computers, having designed early mechanical computers in the 1800s to perform basic arithmetic functions.

In put device An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. ... The most commonly used or primary input devices on a computer are the keyboard and mouse.
? Mouse ? Keyboard ? Scanner ? Touch pad ? Light pen ? Joysticks ? Microphones ? Digital Cameras ? Touch Screen ? Bar Code Reader ? Trackball ? CD-ROM
An output device is any device used to send data from a computer to another device or user. output device
Central Processing Unit (CPU) The central processing unit (CPU) is the unit which performs most of the processing inside a computer. To control instructions and data flow to and from other parts of the computer, the CPU relies heavily on a chipset, which is a group of microchips located on the motherboard.
storage device A storage device refers to a computing hardware used to store information permanently or temporarily. The device can be external or internal to a computer, server, and other computing systems. Storage devices are also known as storage medias or storage medium. There are two types of storage device: secondary storage device and primary storage device.
Secondary storage device A secondary storage device has a larger storage capacity and can store data permanently. The device can be both external and internal to a computer and includes; compact disk, USB drive, hard disk, etc. Primary storage device A primary storage device is quite smaller in size and it¡¯s designed to capture or hold data for a temporary period. Most primary storage devices are found inside the computer, and they have the fastest access to data. Examples of Primary devices include Cache memory and RAM.
