How many different values can be represented in 6 bits?
Binary number representation
|Length of Bit String (b)||Number of Possible Values (N)|
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. It can represent a letter or a shade of green.)
- For example, an 8-bit unsigned number can represent the values 0 to 255 (11111111). However a two's complement 8-bit number can only represent positive integers from 0 to 127 (01111111), because the rest of the bit combinations with the most significant bit as '1' represent the negative integers −1 to −128.
- Data structures containing such different sized words refer to them as WORD (16 bits/2 bytes), DWORD (32 bits/4 bytes) and QWORD (64 bits/8 bytes) respectively.

In hexadecimal notation, 4 bits (a nibble) are represented by a single digit. There is obviously a problem with this since 4 bits gives 16 possible combinations, and there are only 10 unique decimal digits, 0 to 9.
- Binary is a mathematical number system: a way of counting. We have all learned to count using ten digits: 0-9. One probable reason is that we have ten fingers to represent numbers. The computer has switches to represent data and switches have only two states: ON and OFF.
- By including the zeroeth entry you have 256 unique values. Because a byte, by its standard definition, is 8 bits which can represent 256 values (0 through 255). A byte has only 8 bits.
- Method 1 Learning Binary
- Learn what binary means.
- Add one by changing the last 0 into a 1.
- Write another digit if all the numbers are one.
- Use these rules to count to five.
- Count to six.
- Count to ten.
- Notice when new digits get added.
- Practice with higher numbers.
