What Are the Most Important Parts of a Computer?
Computers are made of many different parts. Some parts are essential for the computer to run and some are not. For example, a complete computer without a floppy drive will function properly, except that it will not be able to read floppy disks.
Processor
The processor performs all the computations on your computer. Whenever you open a program, the information is sent to the processor to be processed into usable data. The processor is commonly referred to as the "brain" of a computer.
Motherboard
The motherboard connects all the parts in a computer: the hard drives, optical drives, processor and memory. The motherboard gathers all the information sent by the parts in the computer and processes it in the southbridge, which is a part of the motherboard.
Memory
The memory in a computer helps process data. However, memory is not the main processor and only aids the processor when there are many programs or very demanding programs running on the computer.
Hard Drive
The hard drives store the operating system that you use to operate your computer. For example, Windows or Apple operating systems are stored on a hard drive.
Power Supply
The power supply converts the power coming from the power outlet to the parts in the computer. A power supply has many cables that are all connected to the important parts in a computer, including the motherboard and hard drive. Note that the processor and memory are already connected to the motherboard so they do not need their own power connections.
