Whats bits ?

In computing, a bit is the smallest unit of data and can have a value of either 0 or 1. It is short for binary digit. A group of 8 bits is called a byte, and larger units of data are typically measured in multiples of bytes (such as kilobytes, megabytes, gigabytes, etc.). Bits are fundamental to digital communication and storage, as they are used to represent and manipulate data in binary form.
