Answer :

GinnyAnswer

Final answer:

Solid State Drives (SSDs) have advantages over magnetic hard drives, computer hardware has four primary functions, and various optical drives have different data storage capacities.


Explanation:

a) Advantages of Solid State Drives (SSDs) over Magnetic Hard Drives:

  1. Faster Speed: SSDs offer quicker data access and transfer speeds compared to magnetic hard drives.
  2. Better Durability: SSDs are more resistant to physical damage due to the absence of moving parts.
  3. Lower Power Consumption: SSDs consume less power, leading to improved battery life in laptops.

b) Four Primary Functions of Computer Hardware:

  • Input: Devices that allow data to be entered into a computer.
  • Processing: Involves the CPU carrying out instructions in programs.
  • Storage: Includes both primary (RAM) and secondary (hard drives) memory.
  • Output: Devices that display or provide processed data to the user.

c) Three Optical Drives and Their Maximum Data Storage:

  1. DVD: Maximum capacity of around 4.7 to 9 GB.
  2. Blu-ray: Maximum capacity of up to 50 GB.
  3. HD-DVD: Maximum capacity of around 15 GB.
