byte
A byte, also referred to as an octet, is a unit of space used on computers. Calculation
A byte can be represented in different ways. The first way is by a string of 8 binary (either 0 or 1) digits. Each of these digits is equal to one bit, which means that there are 8 bits in 1 byte. The second way is through two digits in the hexadecimal numbering system, which uses base 16 as opposed to base 10 (i.e. the decimal number system). Each digit in the hexadecimal representation is equal to 4 bits (which is equal to 1 nibble).
If you counted out every possible combination of 8 bits, you would get 256 total possible combinations. Due to this, one byte can hold one of 256 total possible values, which range between either 0 and 255 (unsigned byte) or between -128 and 127 (signed byte).

Bit
Short for binary digit (which comes from the initial 'bi' and the ending 't'), a bit is the smallest unit of information used in computers and other machines. It uses a value of either 1 or 0. Eight bits make up one byte.
