Computer Hardware - Hard Drive

What is the primary function of a hard drive in a computer?

• Store and retrieve data

• Run software applications

• Cool the CPU

• Display graphics

Which unit is used to measure the storage capacity of a hard drive?

• kilobyte

• gigabyte

• byte

• megabyte

What is the difference between HDD and SSD?

• HDD is more reliable and has a longer lifespan than SSD.

• HDD is faster, more durable, and consumes less power compared to SSD.

• SSD is faster, more durable, and consumes less power compared to HDD.

• SSD has a higher storage capacity than HDD.

What does RPM stand for in the context of hard drives?

• Revolutions Per Minute

• Rotations Per Minute

• Rapid Processing Mode

• Revolutions Per Millisecond

What is the purpose of the cache memory in a hard drive?

• To increase the hard drive's storage capacity

• To play music files

• To improve the screen resolution

• To temporarily store frequently accessed data for quicker access

How does fragmentation affect the performance of a hard drive?

• Fragmentation reduces the storage capacity of a hard drive

• Fragmentation causes slower read/write speeds and increased seek times, thus affecting the overall performance of a hard drive.

• Fragmentation improves read/write speeds on a hard drive

• Fragmentation has no impact on the performance of a hard drive

What is the average lifespan of a typical hard drive?

• 1 to 3 years

• 7 to 10 years

• 10 to 15 years

• 3 to 5 years

What is the role of the actuator arm in a hard drive?

• Moves the read/write heads across the disk surface

• Manages the power supply to the hard drive

• Controls the speed of the disk rotation

• Stores data on the disk platters

What is the significance of the platters in a hard drive?

• Platters in a hard drive are used for cooling the device.

• Platters in a hard drive are decorative elements.

• Platters in a hard drive are where data is physically stored.

• Platters in a hard drive are responsible for powering the device.

How does a solid-state drive (SSD) differ from a traditional hard drive?

• SSD consumes more power than traditional hard drives

• SSD has slower read/write speeds compared to traditional hard drives

• SSD uses flash memory, has faster read/write speeds, consumes less power, and is more durable compared to traditional hard drives.

• SSD uses magnetic disks instead of flash memory
