THE HISTORY OF COMPUTING

All you need to know about the computer basics.

INPUT DEVICES

Input devices are devices connecting to the computer. Input devices have a special use. To distinguish between an input device and an output device is An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing.

Output devices

devices are the opposite to input devices they are what An output device is any piece of computer hardware items used to communicate the results of data processing from an information processing system (such as a computer) which converts the electronically generated information into human-readable form.

BINARY CODE

Binary code is a secret code language. Binary is the only language that the computer understands. Allan Turing was a famous man that cracked the binary code. The code consists of the numbers 1 and 0. You can make all the letters of the alphabet using only ones and 0s

An example of binary code is 01000 00101 01100 01100 01111 ( It says hello)

Computer Network

What is a computer network?


A computer network consists of two or more computers that are connected to each other they can share images,videos and more.


Advantages are that they share a printer for example and they can also share images so if one computer isn't working you can still assess your files through another computer from the network. The disadvantages are that there is a bigger chance of catching viruses and the virus can spread rapidly.

Bus Netwrok

The bus network has all the computers connected to a straight line. However the disadvantage of using a bus network is that it is low security however it doesn't cost much.

Star Network

The star network has all the computers joint in he middle to the hub. This i an advantage as it helps monitor the network however a disadvantage as it has too much dependence on the hub and it can slow down or catch a virus.l

Ring Network

The ring network has two or more networks connected to each other in a circle. The advantages are that additional components don't affect the network however the disadvantage is that the network is highly dependent on the wires.
