What is RAID 4?
- Stripping into blocks and parity, needs 3 HDDs
- Mirroring and stripping 2 HDD
- Stripping
Correct Answer

A. Stripping into blocks and parity, needs 3 HDDs

Explanation

RAID 4 is a data storage technology that involves stripping data into blocks and adding parity information. It requires a minimum of three hard disk drives (HDDs) to implement. The data is divided into blocks and stored across multiple drives, with one drive dedicated to storing parity information. This parity information allows for data recovery in case of a drive failure. RAID 4 provides improved performance and fault tolerance compared to a single HDD, but it is less efficient in terms of write operations due to the need to update the parity drive.

- Keyboard
- Mouse
- RAM
Correct Answer(s)

A. Internal hard drive
A. RAM

Explanation

The internal hard drive and RAM are two components that normally require a laptop to be powered down and the battery removed before removing them. This is because both components are connected directly to the motherboard and can be easily damaged if they are removed while the laptop is still powered on. Removing the battery ensures that there is no power running through the laptop, reducing the risk of electrical damage.
