UNDER THE HOOD OF A
COMPUTER

WHAT WE FOUND
We found the following parts of the computer:
RAM
Hard disk drive
Mother board
Power supply unit
Fan unit
HARD DISK DRIVE DRIVE
It is abbreviated as HDD. It is a data storage device used for storing and
retrieving digital information. It uses one or more rapidly rotating disks
coated with magnetic material. Although it may seem the hard disk
drive (often shortened to "hard drive") and the hard disk are not the
same thing, they are packaged as a unit and so either term is
sometimes used to refer to the whole unit.
MOTHER BOARD
A Motherboard holds and allows communication between many of the
most important electronic components of a system, such as the central
processing unit (CPU), memory, etc. A Motherboard contains significant
sub-systems such as the processor and other components.
Motherboard specifically refers to a PCB with expansion capability and
as the name suggests, this board is often referred to as the "mother" of
all components attached to it, which often include sound cards, video
cards, network cards, hard drives or other forms of storage.
FAN UNIT
The fan unit helps cool down the computer when it is heating up. It
automatically switches on when the temperature sensor senses a
certain level of heat. It is crucial to making sure the computer doesn't
heat and/or eventually catch on fire. Without the fan, all computers
can be dangerous to humans.
POWER SUPPLY UNIT
A power supply unit (PSU) converts mains AC to low-voltage regulated
DC power for the internal components of a computer. Modern personal
computers universally use a switched-mode power supply. Some power
supplies have a manual selector for input voltage, while others
automatically adapt to the supply voltage.
RAM
The RAM (Random-access memory) is a form of computer data
storage. A random-access memory device allows data items to be
accessed (read or written) in almost the same amount of time
irrespective of the physical location of data inside the memory
Today, random-access memory takes the form of integrated circuits.
where stored information is lost if power is turned off. Other types of
memory exist that allow random access for read operations, but either
do not allow write operations or have limitations on them. These include
most types of ROM and others.
