Question

question: 2
what is the bitrate of a system?
the number of bits used to encode a single letter
the amount of data (in bits) that can be sent in a fixed amount of time
the strength of the network connection
the distance that data needs to travel in a network

Explanation:

Bitrate is a measure of data transmission speed, defined as the volume of bits transferred within a set time frame. The other options describe unrelated concepts: bit encoding per character, network signal strength, and data travel distance respectively.

Answer:

The amount of data (in bits) that can be sent in a fixed amount of time
