Computer Mission Impossible

All you need to know about computers!!!


There are 9 main parts that make up a computer hard drive/modem! That includes the heat sink, system fan, power supply etc. They all do different things, so for example the system fan stops things from over heating!

Main Parts and their function:

System Fan:

Computer fans are found inside the computer case and help prevent the various computer parts inside from overheating. Without them, components of your computer can malfunction, become damaged, or even crash.

Power Supply:

The component that supplies power to a computer. Most personal computers can be plugged into standard electrical outlets.


A motherboard is also known as a motherboard, system board and logic board. A common abbreviation is 'mobo'. They can be found in a variety of electrical devices, ranging from a TV to a computer.


The function of a floppy disk drive is to provide a means of writing/reading data on/from floppy disks in an industry standardized method. Floppy Disks were invented as an improved means for storing/transporting data on/from computers.

Heat Sink:

A type of protective device capable of absorbing heat and used as a heat shield. In nuclear propulsion, any thermodynamic device, such as a radiator or condenser, that is designed to absorb the excess heat energy of the working fluid. Also known as heat dump.

Hard drive:

A disk drive that reads data stored on hard disks. Also called hard disk drive.

Optical Drive:

Generally refers to a CD-ROM, DVD-ROM or combo CD/DVD drive in a personal computer.

RAM Modules:

RAM stands for Random Access Memory. It is temporary storage for data. For instance, when you open Microsoft Word (or any program), it goes into RAM because your CPU can get it a lot faster from RAM, than if it tried to get it off of your hard drive.

Processors (CPU) :

CPU is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
