In data transmission, how is Kbps defined?

Kbps, which stands for kilobits per second, is defined as the number of kilobits that are transmitted in one second. This unit of measure is commonly used to indicate the speed of data transfer in networking and telecommunications. Understanding Kbps is important as it quantifies how much data can be sent or received over a connection within a given timeframe, which is crucial for evaluating internet speeds or the performance of data transmission technologies.

Other options refer to unrelated concepts. For example, the quantity of kilobytes processed in an hour pertains to a different time frame and measurement unit, while kilohertz is a measure of frequency, not data transmission speed. Finally, the mention of kilowatt hours relates to energy consumption, which is also not relevant to data transmission. Therefore, the correct understanding of Kbps directly ties to its definition as the number of kilobits transmitted in a second.
