The computer is also made of INPUT and OUTPUT devices. INPUT devices are devices that put information into the computer for example like Keyboards, Mouse and others. OUTPUT devices are devices that shows the information you put in like Printers, Monitors/screens and others.

INPUT DEVICES

Input devices are devices that put information into the computer.

Examples of Input devices are:

Mouse

Keyboard

Joystick

Touch pad

Scanner

Optional pen

Microphone and many others

OUTPUT DEVICES

Output devices are devices that produce the information that you put into the Computer.

Examples of output devices are:

Speakers

Head set

Head phone

VDU

Printer

Plotters

HARDWARE DEVICES

Below are some examples of hardware devices

BINARY CODE

A binary code represents text or computer processor instructions using the binary number system's two binary digits, 0 and 1. The binary code assigns a bit string to each symbol or instruction. For example, a binary string of eight binary digits (bits) can represent any of 256 possible values and can therefore correspond to a variety of different symbols, letters or instructions.

ALAN TURING

Who is Alan Turing?

Alan Mathison Turing was born on 23 June 1912, the second and last child (after his brother John) of Julius Mathison and Ethel Sara Turing. The unusual name of Turing placed him in a distinctive family tree of English gentry, far from rich but determinedly upper-middle-class in the peculiar sense of the English class system.In four inadequate words Alan Turing appears now as the founder of computer science, the originator of the dominant technology of the late twentieth century, but these words were not spoken in his own lifetime, and he may yet be seen in a different light in the future. They are also words very remote from the circumstances of his birth and infancy.

COMPUTER NETWORK

What is a computer network?

A computer network is when more than two computer are sharing the same information like pictures, document, etc. There are three main types of computer network:

-Bus Network

-Ring Network

-Star Network

The advantages of a computer network are:

-You can work on any computer connected to the network.

-You can share the same information.

-The internet doesn't need the internet to work.

The disadvantages of a computer network:

-It takes a lot of time to transfer information if there are a lot of computers.

-In some networks, if one computer fails, the rest fail.
