Basic Computing


Input devices are things that send information to the computer. Like keyboards, mice, touch-pad, microphone, remote, and anything that can send data to a computer.


Storage is were information stays, whether it be for a short time like RAM or for ever like a hard drive.


The processing is how the computer reads and interprets information, for example the CPU and Motherboard.


Output is anything that happens after the proses like letters appearing on the screen after typing or the cat video playing.

Computer Hardware

1. Monitor

The visual display for computers. Today computer monitors use tiny things called pixels that show red, green, and blue light to create all the colors of the rainbow.

2. Motherboard

Is the main circuit board found in computers, it holds many of the electronic components of the system such as the CPU and memory.

3. Central Processing Unit (CPU)

Dose most of the calculations to enable the computer to function. It has to be kept cooled.

4. RAM

RAM or Random-Access Memory, stores the data that is being accessed by the CPU.

5. Expansion Cards

Is a printed circuit board that can be put into a slot of the motherboard to add more functionality to the computer.

6. Power Supply Unit

A power supply unit, or PSU, covers AC electric power to low voltage DC power witch the computer uses. Laptops have batteries that store electric energy to use when unplugged.

7. Optical disc drive

Is where you put CDs, DVDs, and Blu-ray discs for them to be read by the computer.

8. Hard Drive

A data storage device used for storing and retrieving digital information

9/10. Keyboard and Mouse/Touchpad

These are stander devise for computers that give it commands to do.

11. ROM

ROM or Read-Only Memory contains the information for booting up.


Troubleshooting is the processes of trial and error when trying to found out why something is not working. One time I did some troubleshooting of my own. You see, I found out that I could hack a game on my phone and at first It went good in till all my saves were unusable. After looking at the code I realised that I remove a important part of the code, I didn't know how to fix it so I deleted the save and started new with a few cheats.


We were given a old computer to troubleshoot on. When we started it up there was no image on the screen. While we were not able to identify the problem we know it was not the monitor because it made an image when it was not attach to the computer so we guess it is the video that needs to be replaced.
