Question 1

What is an LCD (Liquid Crystal Display)?

Answer 1

A display technology using liquid crystals that change properties when voltage is applied.

Question 2

What are the characteristics of a TN (Twisted Nematic) panel?

Answer 2

Fast response times and lower production costs, but poorer color reproduction and viewing angles.

Question 3

What are the characteristics of an IPS (In-Plane Switching) panel?

Answer 3

Better color accuracy and wider viewing angles compared to TN, but more expensive and slower response times.

Question 4

What are the characteristics of a VA (Vertical Alignment) panel?

Answer 4

Offers good color reproduction and high contrast, but slower than both TN and IPS. Commonly used in TVs.

Question 5

OLED (Organic Light Emitting Diode)

Answer 5

Each pixel emits its own light

Question 6

AMOLED (Active Matrix OLED)

Answer 6

A type of OLED used in smartphones that offers improved performance using active matrix technology.

Question 7

Mini LED

Answer 7

A backlighting technology for LCDs that uses smaller LEDs to improve brightness and contrast.

Question 8

Solid State Drives (SSDs)

Answer 8

A solid-state drive is a type of mass storage that uses flash memory to store data

Question 9

Motherboard

Answer 9

The motherboard is the main printed circuit board in a computer. It connects the CPU

Question 10

Removable Storage

Answer 10

Often used for backup or transferring data between devices. They are generally portable and convenient for storing data outside the primary system.

Question 11

Hard Drives (HDDs)

Answer 11

A hard disk drive is a form of mass storage that uses spinning disks (platters) to read and write data.

Question 12

What is RAID 0 also known as?

Answer 12

Striping.

Question 13

What does RAID 0 do?

Answer 13

It splits data across multiple disks to improve performance.

Question 14

What is an advantage of RAID 0?

Answer 14

Faster read/write speeds.

Question 15

What is a disadvantage of RAID 0?

Answer 15

No redundancy; if one disk fails

Question 16

What is RAID 1 also known as?

Answer 16

Mirroring.

Question 17

What does RAID 1 do?

Answer 17

It duplicates data on two disks.

Question 18

What is an advantage of RAID 1?

Answer 18

Provides redundancy; if one disk fails

Question 19

What is a disadvantage of RAID 1?

Answer 19

Storage capacity is halved (only the size of one disk is usable).

Question 20

What is RAID 5 also known as?

Answer 20

Striping with parity.

Question 21

How many disks are required for RAID 5?

Answer 21

At least three.

Question 22

What does RAID 5 do?

Answer 22

It stripes data and parity across multiple disks.

Question 23

What is an advantage of RAID 5?

Answer 23

Good balance of performance and redundancy; can recover from one disk failure.

Question 24

What is a disadvantage of RAID 5?

Answer 24

Slower write speeds due to parity calculations.

Question 25

What is RAID 6 also known as?

Answer 25

Dual parity.

Question 26

How many disks are required for RAID 6?

Answer 26

At least four.

Question 27

What does RAID 6 do?

Answer 27

Similar to RAID 5 but with two parity blocks for extra fault tolerance.

Question 28

What is an advantage of RAID 6?

Answer 28

Can withstand two disk failures.

Question 29

What is a disadvantage of RAID 6?

Answer 29

Write speeds are slower than RAID 5.

Question 30

What is RAID 10 also known as?

Answer 30

RAID 1+0 (Mirroring and Striping).

Question 31

How many disks are required for RAID 10?

Answer 31

At least four.

Question 32

What does RAID 10 do?

Answer 32

It combines mirroring and striping for performance and redundancy.

Question 33

What is an advantage of RAID 10?

Answer 33

Excellent performance and redundancy; can withstand multiple disk failures (not in the same mirrored pair).

Question 34

What is a disadvantage of RAID 10?

Answer 34

More expensive due to the need for more disks.
