Q

What is latency in networking?

a) The variation in the delay of packet delivery
b) The inconsistency in the rate of packet delivery
c) The time it takes for a transmission to reach the recipient
d) The measure of packet loss in a network

A

c) The time it takes for a transmission to reach the recipient

Problems with the timing and sequence of packet delivery are defined as latency and jitter.

Latency is the time it takes for a transmission to reach the recipient, measured in milliseconds (ms).

Jitter is defined as being a variation in the delay. Jitter manifests itself as an inconsistent rate of packet delivery.

Q

What does GSM stand for in the context of 2G cellular digital communications standards?

a) Global System for Mobile Communications
b) General System for Mobile Communications
c) Global Standard for Mobile Communications
d) General Standard for Mobile Communications

A

a) Global System for Mobile Communications

24
Q

What is the key access method used by GSM-based phones?

a) Code Division Multiple Access (CDMA)
b) Frequency Division Multiple Access (FDMA)
c) Time Division Multiple Access (TDMA)
d) Spread Spectrum Multiple Access (SSMA)
