Which of the following accurately reflects the purpose of secondary storage?
Correct Answer
A. Secondary storage is used for permanent storage.
Explanation
Secondary storage refers to the type of storage that is used for long-term or permanent storage of data. Unlike primary storage (such as RAM), which is volatile and loses its data when power is lost, secondary storage retains data even when the power is turned off. Therefore, it accurately reflects the purpose of secondary storage as being used for permanent storage.

What is the best way when working inside a computer to protect against ESD? (choose 2)
Correct Answer(s)
A. Grounding mat
C. Esd wrist strap
Explanation
To protect against ESD (electrostatic discharge) when working inside a computer, it is recommended to use a grounding mat and an ESD wrist strap. A grounding mat provides a conductive surface that helps to dissipate any static charges that may build up on the person or the components. The ESD wrist strap, when properly connected to a grounded surface, helps to prevent the buildup of static electricity on the person by providing a path for the discharge. By using both the grounding mat and the ESD wrist strap, the risk of damaging sensitive computer components due to ESD can be significantly reduced.

29.
Which of the following statements bes describes odd parity?
Correct Answer
C. It makes the ninth or parity bit either a 1 or 0 to make the number of 1s in the 9 bits odd.
Explanation
Odd parity is a method of error checking in which an additional bit, known as the parity bit, is added to a group of bits. The purpose of the parity bit is to ensure that the total number of 1s in the group of bits, including the parity bit, is odd. If the number of 1s is already odd, the parity bit is set to 0, and if the number of 1s is even, the parity bit is set to 1. This allows for the detection of single-bit errors in the data. Therefore, the statement "It makes the ninth or parity bit either a 1 or 0 to make the number of 1s in the 9 bits odd" accurately describes odd parity.
