A kilobit is a unit of digital information that equals 1,000 bits. It is commonly used in computing and telecommunications to measure data transfer rates and storage capacity. The term "bit" stands for binary digit, which is the smallest unit of data in computing, representing a value of either 0 or 1. Kilobits are often used to describe internet speeds, such as in kilobits per second (kbps), which indicates how many kilobits can be transmitted in one second. This measurement helps users understand the performance of their internet connection and the speed at which data can be downloaded or uploaded.
