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 28 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 28; this is the same number of values which an unsigned 8 bit integer can contain (from 0 to 255).
