MOTHERBOARDS

What is it?

A motherboard sometimes called the “Mobo” is the main circuit board found in computers and other advanced electronic devices.

Basic ATX Motherboard

• The motherboard gets its name because it is like a mother to all of the other circuit boards.

• The motherboard is the largest circuit board in the computer case and may have many smaller boards plugged into it.

• It’s the glue that holds all of the most important parts of the computer together.

Motherboard Extra’s

On the motherboard, you will find several expansion cards. Each of these cards has a special purpose

Video Cards

• A video card is an type of card which generates a feed of images to a monitor or display.

• Cheaper computer systems may have integrated video capabilities. These built in video capabilities are less powerful than stand alone video cards.

Integrated Video Cards

Notice: The Blue and White video ports are built into the motherboard

Network Cards• Most modern motherboards contain a wired

internet connection point that allows the user to simply plug their computer into a network.

• Some computes today still use a expansion card to connected either directly or wirelessly to a network

Central Processing Unit

The CPU is the hardware within a computer that carries out the instructions of a computer program by performing the basic operations of the system.

Internal Storage

• The Hard Disk Drive is the internal storage device used in modern computers. It connects to the motherboard by a ribbon or data cable.

Memory• RAM or random access memory is the

components of your computer that are used for short term storage.

• Anything stored in RAM will be lost when the computer powers down.

• Example: if you were to Copy and Paste something, the Copy info is held in the RAM

RAM Slots on the Motherboard

Not every computer has the same number of availableRAM slots.

A computer processes information much like our brains.

• Short-term memory is like RAM

• Long-term memory is like the Hard Drive

• Thinking is like the CPU

Computer CoolingThere are many ways to cool a computer.• Air Cooling uses many fans and metal heat sinks

that soak up the heat, away from the delicatecomputer parts.

Liquid Cooling Options

• Some uses decide on liquid cooling options. These options circulate water inside the computer in tubes using a pump to pull excess heat away.

Power Supply Units

• A power supply unit (PSU) converts AC power to low-voltage DC power for the internal components of a computer

• PSU’s are usually mounted in the back of the computer case

• The computer’s PSU powers every device located inside the case using a series of cables and plugs

PSU Cables

• Some cables plug into the motherboard, others plug into the hard drive or video card.
