What are the different parts of computer system?



Computer Memory::

Computer Memory, in other words, is also called as RAM [Random Access Memory].Computer memory is a thin filament or PCB [Printed Circuit Board] where some electronic components are attached to it.

Computer CPU [Central Processing Unit] performs all its operations and tasks with the help of RAM. The RAM is a type of volatile memory where data is lost once the power is off and computer shutdown or even computer restarts.
The Computer speed mainly depends upon 2 factors computer processor and RAM the higher its configuration higher the speed.

The Computer memory comes in different of sizes, capacity, and cost. Their many variants of computer memory available in the market nowadays such as ddr1, ddr2, ddr3, ddr4 where DDR stands for the dual in-line memory module.

As many of us know that ddr1 and ddr2 are outdated and hence no point in using and purchasing these types of memory. Computer memory comes in varieties of sizes and capacity such as 512MB, 1GB, 2GB, 4GB, 8GB, 16 GB where GB stands for the capacity to hold or store data.

Famous Manufacturer of RAM are::
Dynet, Hynix, Iball, Transcend.

Computer Hard Disk Drive::

The Computer Hard Disk Drive is a type of computer memory and is non-volatile in nature let me explain to you what is non-volatile it means the data is almost stored or saved permanently and can be recalled or retrieve whenever the request demands or call.

The data stored in computer hard disk is not lost when the computer fails to boot or there is a power failure.

The Famous manufacturers of computer hard disk are as follows Seagate, Western Digital, Samsung and so on.

CD/DVD Rom

These are optical drives of the computer system where you can use cd and DVD for better functionality and additional features. With the use of cd and DVD, you can install computer operating system on your fresh and used computer and laptops.

Sound cards convert analog signals into digital signals and hence we can hear sound while playing games and watching videos.

Monitors::

Computer monitors are used to viewing the output presented by the CPU [Central Processing Unit].It is used to view images, graphic, and videos on the screen.

TFT Monitor

Computer monitors come in variety of shapes and sizes before some years people used to use CRT [Cathode Ray Tube] monitors but as the computer 
technology advanced to different level users are using TFT [Thin Film Television] or LCD [Liquid Crystal Display] or LED [Light Emitting Diode] monitors because of its clearer picture quality and better resolutions.

The Famous Manufacturers of Monitors are as follows:
LG, Samsung, BenQ, HP, SONY and so on
