In terms of computer storage, gigabytes (GB) are bigger than megabytes (MB). Kilobytes (KB) are smaller than megabytes, and terabytes (TB) are larger than gigabytes.
One byte of memory contains enough information for one character, which could be a letter, number or symbol. A single byte consists of 8 bits, which are essentially binary placeholders in a string, that can either be one or zero. These bits together communicate the information needed for a specific character.
There are 1024 bytes in a single kilobyte, and 1024 kilobytes in a single megabyte. The pattern continues, as there are 1024 megabytes in a gigabyte, and 1024 gigabytes in a terabyte.
