The history of computing
everything you need to know
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
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
plus they are all inside a computer.
CPU stands for Central Processing Unit this is referred to the "Brain' of the computer.
RAM stands for Random Access Memory
RAM is a type of computer memory that can be accessed randomly
the power supply is an internal hardware component that supplies components.
Network card is an electronic device that connects a computer to a computer network, usually a LAN. It is considered a piece of computer hardware. Today, most computers have network cards.
A Graphics Card is a piece of computer hardware that produces the image you see on a monitor. The Graphics Card is responsible for making an image to your monitor, it does this by converting data into a signal your monitor can understand
the mother board is the main printed circuit board found in general purpose microcomputers and other expandable systems.
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.
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.

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
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).
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.
