Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is meant by latency in the performance of a network? (6-9)
A
The amount of time data takes to travel from the source to the destination
B
The maximum rate that data can be transferred at
C
The number of errors that are found in a data packet after transmission
D
The route a packet takes when it is being transmitted
Explanation: 

Detailed explanation-1: -Network latency is the delay in network communication. It shows the time that data takes to transfer across the network. Networks with a longer delay or lag have high latency, while those with fast response times have low latency.

Detailed explanation-2: -Latency describes the amount of delay on a network or Internet connection. Low latency implies that there are no or almost no delays. High latency implies that there are many delays. One of the main aims of improving performance is to reduce latency.

Detailed explanation-3: -Measure of the responsiveness of a network, often expressed as the round-trip time (in milliseconds); that is, the time between initiating a network request and receiving a response. High latency tends to have more impact than bandwidth on the end-user experience in interactive applications, such as Web browsing.

Detailed explanation-4: -In computer networking and internet communications, data latency is the time it takes data to travel from a source to a destination.
