COMPUTER SYSTEM UNIT-COMPONENTS & FUNCTION

We all use computers on our daily basis. But have you really wondered how did our computers work? Most of us use computers but never even thought about how computers work and what is hidden inside the realm of the plastic case. However, while they still exist, it's necessary to know what's there inside them and how it all works.

 WHAT IS COMPUTER SYSTEM UNIT?

In accordance with the definition of a system unit, it is technically a chassis, which is filled with different appliances and details. These details and devices and systems and everything else inside the chassis makes up a computer. Functionally, the system unit is a base for the creation of a regular electronic system, which we all know as a computer. So basically, COMPUTER SYSTEM UNIT provides functions of many parts and is responsible for practically everything except showing the pictures.

COMPONENT OF COMPUTER SYSTEM UNIT

What we usually see from the outside is the chassis. Everything else is hidden inside. So, let's take a look at what's actually hidden in the system unit. I have listed the components you are going to find inside your system unit.  

        1. MOTHERBOARD.

A system core. Actually, it is the heart of the computer. Other system elements are connected to the motherboard, and the whole system is managed and controlled by it. The motherboard contains special chips on which some ICs (Integrated circuits) are etched.

        2. POWER SUPPLY

An electronic device that supplies electric energy to an electric load. Its main function is to convert one form of electrical energy to another and as a result, power supplies are sometimes referred to as electric power converters.

        3. HEAT SINK

            A component designed to lower the temperature of the computer.

        4. PROCESSOR

A computer engine, its brain. CPU (central processing unit) manages most of the computer operations. Processors can be with pins or pin-less. It contains a control unit and a logic unit.

       5. RAM ( Random Access Memory )

A system memory that storages data in a form of archives. Here all our files, folders, operating system, programs, and applications are saved.

        6. GRAPHICS/VIDEO CARD

Graphics cards allow computers to produce graphics and images more quickly. A graphics card has its own processor, a GPU, or graphical processing unit, according to Jason Cross at PC World. The video card connects to the motherboard and the monitor. This allows the card to accept information from the CPU (central processing unit) and send output to the monitor.

     7. NETWORK CARD

A network interface card (also known as a NIC, network card, or network interface controller) is an electronic device that connects a computer to a computer network, usually a LAN. It is considered a piece of computer hardware.

      8. HARD DISK

A hard disk is a non-volatile memory hardware device that permanently stores and retrieves data on a computer. Its also secondary storage devices that consist of one or more platters to which data is written using a magnetic head, all inside of an air-sealed casing.

        9. CPU ( Central Processing Unit )

       

The central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. It performs the basic arithmetical, logical, and input/output operations of a computer system.

        10. SYSTEM CASE

System Case holds all the other component together and protects the sensitive electronic parts from the outside elements.

        11. CD ROM

A device that uses photodiodes to detect reflecting lights on the optic disc and uses a laser to read or write data.

        12. PORT

An interface between a computer to another computer or peripheral devices, a mainly used port is the USB port.

DISASSEMBLE AND ASSEMBLE THE SYSTEM UNIT

So, in case you guys want to check all the components out I make this video so you guys wouldn't ruin your system unit. Enjoy! :) 

Now you know practically everything about the computer chassis and all the stuff inside it. As you can see, the inner world of a computer is actually very interesting. 

If you guys do have something to ask or just want to talk with someone or if you guys want to suggest content for my next post you can reach me on my social media or by email.;) thank you. Lots of love.
