Question 12

What does the hard drive do?

Comuter systems

Answer 12

• They are physical storage devices that store both permanent and temporary data in different formats, including programs, OSes, device files, photos, etc.
• It stores everything that has been saved to this storage for the full computers history.

Question 13

What does the Optical drive do?

Comuter systems

Answer 13

• Optical drives typically reside in an on-device drive bay; they enable the computer to read and interact with nonmagnetic external media, such as compact disc read-only memory or digital video discs.
• It allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie.

Question 14

What does the heat sink do?

Comuter systems

Answer 14

• This is a passive piece of hardware that draws heat away from components to regulate/reduce their temperature to help ensure they continue to function properly. Typically, a heat sink is installed directly atop the CPU, which produces the most heat among internal components.
• It removes heat form the devices components to improve device performance and extend its life.

Question 15

What does the graphics processing unit do?

Comuter systems

Answer 15

• This chip-based device processes graphical data and often functions as an extension to the main CPU.
• It is responsible for calculating images in a computer, which can then be displayed on a monitor.

Question 16

What does the network interface card (NIC) do?

Comuter systems

Answer 16

• A NIC is a circuit board or chip that enables the computer to connect to a network; also known as a network adapter or local area network adapter, it typically supports connection to an Ethernet network.
• It provides a computer with a dedicated, full time connection to a network.

Question 17

What is a primary storage?

Storage Devices

Answer 17

• Used to store programs and data that are currently being used.
• It is much quicker to access than secondary storage.
• Exists in smaller quantities than secondary storage.

-It is always volatile (except ROM)

• E.g.
  - RAM
  - ROM
  - Cache

Question 18

What is secondary storage?

Storage Devices

Answer 18

• Used to store all programs and data for a computer system.
• It is much slower to access than primary storage
• It exists in much larger quantities that primary storage (2TB).
• It is non-volatile
• Examples are
  - Hard drive
  - Solid State Drive
  - CD-ROMs
