1. Register
2. CPU
3. RAM
4. HDD

Answer 1

Correct Answer - Option 4 : HDD

The correct answer is HDD.

• A laptop used for normal office work is likely to have a typical HDD(Hard Disk Drives) capacity of 512 GB.
• About HDD (Hard Disk Drives):
  • An HDD is a data storage device that lives inside the computer.
  • It has spinning disks inside where data is stored magnetically.
  • The HDD has an arm with several "heads" (transducers) that read and write data on the disk.
  • It is similar to how a turntable record player works, with an LP record (hard disk) and a needle on an arm (transducers).
  • The arm moves the heads across the surface of the disk to access different data.
  • They are available in two common form factors that are 2.5 inches (commonly used in laptops) and 3.5 inches (desktop computers).

• About Register:
  • A register is a temporary storage area built into a CPU.
  • Some registers are used internally and cannot be accessed outside the processor, while others are user-accessible.
  • Most modern CPU architectures include both types of registers.
• About CPU(Central Processing Unit):
  • The computer's central processing unit (CPU) is the portion of a computer that retrieves and executes instructions.
  • The CPU is essentially the brain of a CAD system.
  • It consists of an arithmetic and logic unit (ALU), a control unit, and various registers.
• About RAM:
  • RAM is a volatile memory.
  • RAM is essentially short-term memory where data is stored as the processor needs it.
  • This isn't to be confused with long-term data that's stored on your hard drive, which stays there even when your computer is turned off.
