Processing Devices
1. Processor:

Processor is the main core device
available in the computer. It is the brain of the computer which gives receives
signal came from input devices, process it and gave useful information to user.
Processior came in different variants according to the use and functions of
computer. It is installed inside the motherboard and it control the workflow of
motherboard all devices. It is most expensive part of the computer. Without
Processor, motherboard do not connect with any part of the computer and cannot
receive and process signals in the computer.
2. Motherboard:
Motherboard is also a main part of Central
Processing Unit. It acts as a platform to another devices to connect and
transfer signals from one device and another. The processor is also installed
on motherboard. Motherboard provides ports such as USB port, earthnet port,
audio port, video port and many other ports to connect external devices with
the computer. The motherboard also provide slots for inside devices in CPU such
as Hard disk, Randam Acccess Memory (RAM), and Processor, CD Drive, etc.
Motherboard is also known as nervous system of the CPU.
3. Random Access Memory:
Random Access Memory which is commonly
known as RAM is a device installed over motherboard, which store data in
temporary form. The main purpose of ram is to provide data faster and easily
for processing for short period of time. When any application is run on the
computer, the RAM access data from the Secondary Storage devices such as Hard
disk or SSD and process data very fast and quickly in short period of time.
Let’s understand this phenomena with an example, when a user open any
application, the processor give signals to RAM to open the files which is
stored in the secondary memory such as Hard drive, to execute the application.
The RAM quickly searches the relevant data inside the hard drive and save it in
its memory for quick execution. Untill the application runs, all the data
received from application is stored in the RAM. All the instructions and
changes made inside the application are saved in the RAM. When user closes the
application, data stored inside the RAM transferred to the secondary memory where
the data is permanently saved. The data saved on the RAM is temporary and if there is any power
failure or any other issues occurred which fails the user to save the changes,
all the data and changes are wiped off from the RAM Memory and cannot be retrieved
once deleted. This is why the RAM is known as Temporary memory and all the data
saved in the RAM memory is temporary and will be wiped off, if not transferred
or stored in secondary memory. The
storage capacity of RAM is normally 1 to 2 GB nowadays. It stores data for
short period of time and for temporary basis only.
4. Power Supply:

Power supply is
a device which is available inside the CPU. The main work of power supply is to
convert Alternating Current into Direct current and supply it to the another
devices available inside the computer. It is also known as Power Supply Unit
(PSU). The Power supply has many small connectors having different voltage such
as 5 Volt, 12 Volt etc and can be easily connected with another devices which
require power to operate. For Example, power supply is connected with
Motherboard, CD/DVD Driver, Harddisk, Floppy Driver and another devices
available inside the computer. All the power consumes by Processor Unit, RAM
Slots, motherboard components are supplied by power supply unit.
Cooling Unit:
Cooling unit is
also a part of processing unit which is used inside CPU. The main purpose of
Cooling unit is to maintain the temperature of processor. The major workflow of
computer is operated by the processor
unit and the processor unit temperature increases and it got overheated during
performing operations. To maintain the temperature of Processor Unit and
prevent it from overheated, Cooling unit is introduced inside the CPU. It gets
installed over the processor unit and it maintains the temperature of processor
unit with the help of Heat Sink and Fan. Nowadays, Liquid Coolant is also
introduced inside the Cooling unit for faster cooling of processor unit.
i) Fan:
Fan is a common device used to maintain
the temperature inside processor unit. Fan is also installed over CPU casing as
well as inside the power supply unit to evacuate the heat generated inside the
CPU during component’s operation. Fan is generally fitted over the processor
unit with the help of Heat Sink.
ii) Heat Sink:

Heat sinks are the device commonly
fitted over the parts where immense heat is generated during device
performance. It is made of mixed material which are generally sinks the heat
from the device and helps to maintain the temperature of the device. Heat sinks
are generally fitted over Processor unit to overcome the overheat problem of
processor unit. It also helps in increases the performance of processor unit
and helps to run the processor unit smoothly and with better performance.
iii) Liquid Cooling:
Liquid Cooling is also a part of
Cooling unit, in which a liquid is introduced in place of heat sinks to prevent
processor unit and other devices such as Graphics Card from overheating
problem. Cooling liquid absorbs the heat from the devices and helps them to
perform better. There are different types of cooling liquid available nowadays,
but the most common liquid used for cooling is water. Liquid Cooling now
generally used in today’s computer having higher graphics and speed.
