Hard Drive/SSD

A hard drive is a computer device which you can save different things onto. Inside the component, there is a disc which spins and there is also a metal arm which reads and writes documents onto the Hard Drive. The SSD(Solid State Drive) is similar to a hard drive but is more expensive.

Optical Drive

This particular device is Blu Rays, DVD's, cd's and video games. A blue laser reads the spinning disc and reads/writes documents.


A monitor is the screen of the computer in which you can see what you are doing. Some advanced monitors have webcams.

CPU(Central Processing Unit)

The CPU is the "brain" of the computer. The faster the CPU is, the faster the computer will run. The rate of the CPU is in gigaherts.

A motherboard is a device which connects all the parts together. A motherboard allows all the parts of your computer to receive power and communicate with one another.

RAM(Random Access Memory)

A RAM is more storage space on a computer. The RAM in a computer temporarily stores information and processes onto it. For instance, copying a piece of text is temporarily stored on the RAM and then when you paste, it will be off the RAM.


Inputs are the signals of data that are being recieved by the system, and the outputs are the signals of data going out of the system. Printers could be considered outputs and a mouse could be seen as an input.

Touch screens

A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. A stylus could also be used on a touch screen. Touch screens are commonly used in Apple devices, but are used in other kinds of devices, such as a Nintendo DS.
