Why? 2 answers What measures network performance and represents the maximum amount of data?Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given amount of time.
What measures network performance by the maximum amount of data that can pass from one point to another in a unit of Time quizlet?We measure network performance in terms of bandwidth, the maximum amount of data that can pass from one point to another in a unit of time. Bandwidth is similar to water traveling through a hose.
Is the amount of data that can be transmitted across?Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).
What is the term that describes the maximum amount of data that can be sent in a fixed amount of time?Bandwidth is the maximum amount of data that can be transmitted over a network path in a fixed amount of time. Bandwidth is measured in bits per second (bps).
