How many bits are in one Kilobit (Kb)?

One Kilobit (Kb) contains 1,000 bits. This is based on the metric system where "kilo" signifies a factor of 1,000. In networking and data transfer contexts, Kilobits are often used to measure bandwidth and data rates. Therefore, the correct understanding of this measurement aligns with the definition of Kilobit, which directly leads to the conclusion that it is equal to 1,000 bits.

The other choices represent larger units: 1,000,000 corresponds to a Megabit (Mb), which is 1,000 Kilobits; 1,000,000,000 represents a Gigabit (Gb), which is 1,000 Megabits; and 1,000,000,000,000 denotes a Terabit (Tb), which is equivalent to 1,000 Gigabits. Understanding these values helps in grasping the scale of digital data measurement.
