Bit and bytes
Bit is short for binary digit. It’s the smallest and most basic unit of data a computer can store. Computers usually store the bit as zeros or ones. A byte is a group of eight bits. It contains enough information to store a single letter or number. Similarly, a kilobyte (KB) is a collection of 1,000 bytes. The following data measurements are similar to a bit:
- 1 megabyte is 1000 kilobytes
- 1 gigabyte is 1000 megabytes
- 1 terabyte is 1000 gigabytes
- 1 petabyte is 1000 terabytes
