Sometimes you hear a group of four

**bits**called a nibble. The largest**number**you can represent with**8 bits**is 11111111, or 255 in decimal notation. Since 00000000 is the smallest, you can represent 256 things with a byte. (Remember, a bite is just a pattern.Thereof, what is an 8 bit system?

In computer architecture,

**8**-**bit**integers, memory addresses, or other data units are those that are**8 bits**(1 octet) wide. Also,**8**-**bit**CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.How many different combinations are available with an 8 bit system?

So for 1 byte, which is 8 bits, there are 2

^{8}possibilites,**256**. There are several methods: 2^n where n is the number of bits (2^8) Each bit has 2 possibilities. Unsigned value of all 1's + 1 (**255**+ 1) Count up from**0**to max value (all ones) + zero.What is an 8 bit integer?

The number of

**integers**between -128 and + 127 (inclusive) is 256, which is 2**; this is the same number of values which an unsigned**^{8}**8 bit integer**can contain (from 0 to 255).
