What is the main function of a motherboard?

• Provide electrical power to all components.

• Process data from the end user.

• Provide temporary memory during processing data.

• Connects all other components to the CPU.

Why does Hard Disk Drive (HDD) is slower compared to Solid State Drive (SSD).

• Use cable as the connection to the motherboard.

• Heavily depends on the rotational speed of the disk

• The size of the disks are too thick.

• Power run through the SATA cable is not enough.

What is the main purpose of a computer having a Graphics card?

• Just to allow the user to play high end video games.

• Output graphics to the display.

• Provide permanent storage to install programs.

• Process data from the RAM

What are the purposes of Power Supply in a computer?

• Cooling down the heat generated from the CPU.

• Connects the CPU to other components.

• Distribute power throughout the components of the computer.

• Output graphics to the display.

Why does the motherboard have a CMOS battery on it?

• As emergency power to the computer when there is electrical disturbance.

• To power the BIOS chip when the computer is off.

• To provide electrical power to the RAM.

• To power other peripherals connected to the motherboard.
