The Wonderful History of Computing
Find out what you haven't been thinking of!
Input Devices
Input devices are devices which are used to insert information into the computer system which is followed by a procession.
Here are brief examples of input devices:
.Computer mouse
.Keyboard
.Controllers
.CD's
.Joystick
.USB sticks
Output devices
Here are some examples of Output devices:
- Monitor
- IPad
- Speakers
- Printer
Hardware devices
Hardware devices are devices which are physically touched to insert information into a computer.
Processing and Storage
CPU
If a CPU is damaged your computer won't work although it's the smallest thing inside your computer.
RAM
The RAM is in control of the amount of files you have open.
If you open too many files your computer starts to do things slowly unless you've got a lot of RAM.
Graphics Card
Power Supply
Motherboard
If the motherboard doesn't work then the computer won't work.
Hard Drive
BINARY CODE
Binary code, as you may have realized from the beginning bi, is made up of two different numbers; 1 and 0
Why Binary?
The CPU wouldn't understand the text so it is transformed into a code.
This is Binary code!
Alan Turing-
Born: June 23, 1912, Maida Vale, London, United Kingdom
Died: June 7, 1954, Wilmslow, United Kingdom
Education: Princeton University (1936–1938), more
History
He was one of the world's greatest mathematicians and had a great understanding in computing.
His contribution had stopped the Germans sending messages through a secret code because he and a team had cracked the code using a machine he has invented and information from a lady.
He also used enigma to crack the code.
Network
A network is when two or more computers share information because they are connected with a hub and switch or a router.
Router
Hub and switch
Network
Other types of networks
Bus network
- Easy to install
- Cheap and doesn't require much cables.
Disadvantages:
- If the main cable fails or gets damaged the whole network will fail.
- As more workstations are connected the performance of the network will become slower because of data collisions.
Star network
Advantages:
- high performing as no data collisions can occur
- Easy to set up
Disadvantage:
- extra hardware required (hubs or switches) which adds to cost
- Extra hardware required.
Ring network
Advantages:
- Data is quickly transferred.
- Transformation of data is simple.
Disadvantages:
- Difficult to troubleshoot.
- Total dependence on one cable
