What is hardware?
Computer hardware is the collection of physical elements that
constitutes a computer system.

Internal Components
The motherboard
Printed circuit board.
Houses most internal components.

The processor
Carries out instructions given by computer programs.
Handles all the day to day tasks that a PC has to do.

RAM
It deals with temporary data requests such as keeping windows
open.
The more RAM you have, more windows and processes can be
open.
Hard disk drive
Data is retrieved by using a series of disks that store the
data.
The spindle writes the data to the magnetic disk.

CD-Rom drive
They use laser beams to read the data on the disc.
Drives like this one connect to the motherboard via SATA
cables.

Power supply
Converts mains AC electricity into DC electricity that powers
all the internal components.
Power cable
Are connected to the Power Supply Unit and cables that look like
this power the motherboard and is the largest connector found on a
PCs motherboard.

FAN
Sucks cool air into the PC case, blows hot air out of the case
and stops any key components overheating.

Graphics card
They processes and produces outputs for displays. These are a
crucial component that monitors rely on. They also handle output of
video to projectors.
Solid state drives (SSD)
They are a form of computer data storage. They are faster than
traditional hard disks, but they have less storage.

USB cables.
Mouse
It's the primary way of navigating a computer. The mouse used to
have a ball that could move in any direction. Now, They have infra
red lasers.
