Which term is used to denote the transmission capacity of a communication channel?

The term that denotes the transmission capacity of a communication channel is bandwidth. Bandwidth refers to the maximum amount of data that can be transmitted over a communication channel within a given timeframe. It is usually measured in bits per second (bps) or its multiples such as kilobits, megabits, or gigabits per second. Essentially, bandwidth determines how much information can be sent and received over the connection, influencing the performance and speed of data transfer.

While other options relate to data transmission, they describe different aspects of communication. Bitrate refers specifically to the number of bits conveyed or processed per unit of time. Throughput represents the actual rate of successful data transfer over a channel, which can be affected by various factors such as network congestion or interference. Frequency relates to the range of electromagnetic waves used and is important in defining the physical characteristics of a channel, but it does not directly measure transmission capacity like bandwidth does. Therefore, bandwidth is the most appropriate term for denoting the transmission capacity of a communication channel.
