What's Inside a Computer

Whats on a Motherboard


The computer system's component, performs the basic operations (as processing data) of the system, that exchanges data with the system's memory, and that manages the system's other components —called also processor.


Ram stands for random access memory. Ram type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.RAM is the most common type of memory found in computers and other devices, such as printers.


The processor is like your brain,it's where all the processes are carried out ( like thoughts in your head)

Power Supply

Just like your hearty pumps blood around your body, the power supply, pumps electricity around the computer.

Hard drive

The hard drive is where all of your documents, picture, programs and loads of other things are stored onto your computer, similar to all of the long term memories in your brain.

CPU fan

A CPU fan is a device that blows heat away from a CPU chip and other hot-running chips such as a graphics processor (GPU). So the as the CPU does not over heat.


The mother board is like you central nervous system. It sends messages to all of the components inside your computer like your nerves send signals to different parts of your body.

North bridge

North bridge or host bridge is one of the two chips in the core logic chip-set on a PC motherboard. Unlike the southbridge, northbridge is connected directly to the CPU via the front-side bus (FSB) and is responsible for tasks that require the highest performance.

South Bridge

The southbridge is one of the two chips in the core logic chipset on a PC motherboard, the other one is the North bridge. The southbridge typically help the slower capabilities of the motherboard in a northbridge/southbridge chipset computer architecture.

Digital Visual Interface (DVI)

Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group. The digital interface is used to connect a video source, such as a display controller to a display device, such as a computer monitor.

A network interface card (NIC)

A network interface card (NIC) is a circuit board or card that is installed in a computer so that it can be connected to a network.


Stands for "Universal Serial Bus." It can be used to connect keyboards, mice, game controllers, printers, scanners, digital cameras, and removable media drives.

Audio Jacks

    A socket for plugging in an audio source. Audio jacks are found on many types of audio equipment and musical instruments that accept external sound sources.

PCI slot

Stands for "Peripheral Component Interconnect." It is a hardware bus designed by Intel and used in both PCs and Macs. Its used to connect computers and laptops with other devices

PCI-E slot

Unlike earlier PCI standards, PCI Express does not use a parallel bus structure, but instead is a network of serial connections controlled by a hub on the computer's motherboard.

CMOS battery

A battery that maintains the time, date, hard disk and other configuration settings in the CMOS memory. CMOS batteries are small and attached to the motherboard.

SATA port

The standard hardware interface for connecting hard drives.

IDE Connector

It is a standard interface for connecting a motherboard to storage devices such as hard drives and CD-ROM/DVD drives.

AGP slot

A hardware interface from Intel for connecting a display adapter (graphics card) to a PC.

VGA port

The 15-pin VGA connector is found on many video cards, computer monitors, and high definition television sets. It's a video graphics array!
