Parts of the rear panel

"Hi everyone, I'm Rudra, a CS engineer and passionate blogger. Welcome to my post on [ Parts of the rear panel ], where I'll share insights on Information Technology and Computer Science education. My goal is to provide helpful information and answer your questions. Feel free to ask me anything in the comments below. Let's dive into today's topic…🙂”

Parts of the Rear Panel:-

(The remaining answer of the previous question PC System) ← click on this heading


If you look at the rear panel of the system unit of your PC, you will see certain holes and slots fitted with different cables. In this figure to show some ports of the rear panel.

ports of rear panel


Video Port for Monitor 

This is a socket used to connect a monitor with the system unit.

Keyboard Part 

This is used to connect the keyboard with the system unit. Generally it is a PS/2 Port model but the newer model today is going USB port such as uses in the Laptops and Newer Desktop computer CPU cabinate.

Power Sockets

Cables plugged into these sockets carry electric power supply from the electrical outlet to your system unit and from the system unit to your monitor.

Parallel, Serial Port or Sockets and USB Port

These ports or sockets are used for expanding the capability of your PC. For Example, you can connect a printer, mouse, modem or some other peripheral to your system unit by using these ports.Serial port is used to connect a modem or a mouse. Parallel port is used to connect a printer. USB (Universal Serial Bus) port is used for pen drive,etc.

Fan Housing

The power supply fitted inside the system unit has a small fan to take the heat out of the machine. You should make sure that the system unit is placed away from the wall so that the hot air from the fan of the supply unit can be thrown out.

Can a CPU fan reduce heat inside the cabinet of a CPU on a desktop computer?

CPU heats up when it is working on processing the program files on the computer system and operating system scheduled programs that have so many loads to process it.

The CPU processes the programs that means the CPU heats up during processing the data and program files.

The fan over the CPU installed inside the CPU cabinet that can cool the CPU chip and the Aluminium shield also reduces the temperature of the CPU chip.

The CPU fan heat is thrown out of the CPU cabinet of the desktop computer.
