A kilobit is a thousand bits in data transfer. It's used to calculate how much data is transported per second. Kilobits per second is abbreviated as kb/s, Kbps, or kbps (as opposed to Kilobytes per second, which is abbreviated as KBps). Take notice of the capitalization. Bits are generally represented by the lowercase b, while bytes are represented by the capital B. The smallest unit that a computer can handle is the bit (b). A byte (B) is a collection of eight bits. Data transfer speed over the networks is calculated in terms of bits per second: kilobits (kb small case “k” and small case “b”). The higher the kbps i.e., the more the bits transferred per second, the more the speed, the faster the network/connection.
