Assuming the number holds an unsigned number, the range of numbers for 4 bits is 0-7. 7 is a prime number.
An N-bit integer holds 2N different values.For an unsigned integer, the range of values is 0..2N-1 thus.For a signed integer using 2s complement, the range is -2N-1..+2N-1-1.Therefore, the largest positive number that can be stored using 8 bits is 255.
If it is unsigned representation (meaning high bit is not sign bit) then it is 7F which has a decimal equivalent of 127. If it is a signed number (meaning high bit is sign bit) then numbers range from decimal -64 to +63
If all the numbers are the same, the set has no range. The range is zero.
the range of a set of numbers is the difference between the highest value and the lowest value
Range of 8 bit signed number is -128 to 127 Reference: digital fundamentals by Floyd

2n, where n is the number of bits available.
if it is a signed int the the range is -32768 to 32767if its unsigned then 0 to 65535
It goes up to 255, as do the three following numbers. The reason is 255 is the highest value that can be stored as an unsigned 8-bit integer, and when IP was designed, the number of addresses available was thought to be large enough.
2^12 = 4095 is the maximum range of 12bit word
A 32 binary number is a number stored by a computer in 32 bits. it can represent: 1) An unsigned number in the range 0 to 4,294,967,295 2) A signed number in the range -2,147,483,648 to 2,147,483,647 3) A single precision IEEE floating point number with 1 sign bit, 8 exponent bits and 23 mantissa bits give an accuracy of about 7.2 decimal digits and a range of ± 10^-38 to 10^38

The value range. Example for 16-bit integers: signed: -32768..32767 unsigned: 0..65535
We need signed integers in order to represent both negative and positive values. However, some numbers can never be negative. For instance, the size of a file must always be greater than or equal to zero so we use unsigned integers to represent file sizes. Also, natural numbers must be greater than 0 so there's no point in using a signed value to represent a natural number. Signed integers also use one bit to denote the sign, but unsigned integers do not thus unsigned integers can effectively represent twice the range of positive values than an unsigned integer can. For instance, an 8-bit signed value can represent values in the range -128 to +127 using twos complement notation, but an 8-bit signed value can represent values in the range 0 to 255.

Nobody knows what you are talking about, but if you mean what the biggest number is in a byte, it is 255 or 127. The former is only for unsigned, while the latter is the maximun if the byte is signed. If you mean how many numbers can be represented, it is 256 or 128. Again, the former is if it is unsigned and the latter is if it is signed.
