Signed integer is any integer that carries negative sign while unsigned integer is any integer that carries positive sign
The largest unsigned integer is 26 - 1 = 63, giving the range 0 to 63; The largest signed integer is 25 - 1 = 31, giving the range -32 to 31.
From (-215) to (215 -1). In decimal -32768 to 32767.
2n, where n is the number of bits available.
The signed integer range extends only from negative infinity to positive infinity. You have to make up your own names and symbols for whole numbers that are not included in that range.

Type size of an unsigned integer is compiler specific. Most compilers will provide 4 bytes, but the size can range from 2 to 8, or (again) whatever the implementation provides. Note: 1. Maximum value: UINT_MAX (in limits.h) 2. Size in bytes: sizeof (unsigned)
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.
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.
