The history of computing

everything you need to know

Input devices

Input devices:

input devices are things for example a mouse, keyboard, joy stick and many other things here are some pictures of output devices:


a printer is a very good example because

output devices

output devices are things for example a printer, scanner, speakers and many other things here are some pictures:


A printer is a very good example because from the computer you cans send the document to the printer and the printer will print it for you and then you get the final product out in the end

processing

they are all internal processing devices here are some examples:

plus they are all inside a computer.

hard drive

A hard drive can be used to store just about any type of data, including pictures, music, videos, and text documents. Computers have a hard drive and use it to store files for software that run on the computer, as well as files created or downloaded to the computer by a user.

binary code

binary code is a code that is only using 000s or 11111s to make a code that only people who know what 0 and 1 stands for.

binary code is used to make secret messages to each other

or for people that had to write a message that only some people can look at and understand.

Gottfried Leibniz was the person who invented binary code in 1679.

Alan Turing

Alan Turing was the one responsible for ending world war 2.

he cracked the enigma machine.

here is a link to the full movie about how Alan Turing cracked the enigma code: the imitation game 2014 full movie (YouTube)

this is a very good YouTube video because it show hoe he has cracked the enigma code.

i really enjoyed it.

Networking

Networking is more than one computer allowing people to communicate and share information and data.

The things you need for making a network are: network cables such as a hub, routers, wireless network adapter and you will need a modem.


A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

Types of layouts

Disadvantages

RING: If one of the ports go down the entire network gets affected.

STAR: Requires more cable length than any of the other layouts.

BUS: In this type of topology, all the nodes (computers as well as servers) are connected to the single cable (called bus).

Advantages

RING: A network server is not needed to control network connectivity between each workstation.

STAR: Network the best advantage is when there is a failure in cable then only one computer might get affected and not the entire network.

BUS: it works very well when you have a small network.
