Explanation

The smallest amount of data units is a bit. It holds the value of 1 and 0.
Eight 1s and 0s will equal into a byte.
It consisted of Eight bits due to the fact that early computers could only send Eight bits at a time so it was only logical to start with Eight bits equal a byte.
A bit is represented with a lowercase "b," whereas a byte is represented with an uppercase "b" (B). So Kb is Kilobits and KB is Kilobytes.
A Kilobyte is eight times larger than a Kilobit.
