Chapter 3 - Understanding and Accessing Hardware

1. What is the main function of a motherboard?

• 1. Provide electrical power to all components.

• 1. Process data from the end user.

• 1. Provide temporary memory during processing data.

• 1. Connects all other components to the CPU.

1. CPU and Chipset on the motherboard connect all components together. Which of the components or peripherals are not handled by the motherboard?

• 1. RAM

• 1. Ethernet and Wifi

• Display

• 1. Keyboard and mouse.

1. What is the purpose of Voltage Regulator Module (VRM) on the motherboard?

• Cooldown the heat produced by the CPU.

• 1. Provide electrical voltage to the CPU.

• 1. Reduce the voltage from the power supply to the CPU.

• Provide temporary memory for the CPU to process data.

Why does the motherboard have a CMOS battery on it?

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

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

• 1. To provide electrical power to the RAM.

• 1. To power other peripherals connected to the motherboard.

A computer has several types of memory. Which hardware does the computer used as a temporary storage to process data?

• Hard Disk Drive (HDD)

• Solid State Drive (SSD)

• Random Access Memory (RAM)

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

• Power run through the SATA cable is not enough.

• Use cable as the connection to the motherboard.

• The size of the disks are too thick.

• Heavily depends on the rotational speed of the disk

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

• 1. Output graphics to the display.

• 1. Allow the user to play high end video games.

• 1. Process data from the RAM.

• 1. Provide permanent storage to install programs.

What are the purposes of Power Supply in a computer?

• Cooling down the heat generated from the CPU.

• Distribute power throughout the components of the computer.

• Connects the CPU to other components.

• Output graphics to the display.

How many Volts does the Power Supply outputs to the storage drives?

• 3.3V

• 5V

• 12V

• 24V

What does the 80 Plus Rating means on a power supply?

• The power supply is using at least 80% recycled materials.

• The power supply able to output at least 80W.

• Power supply able to output at least 80% from the input power.
