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.
a signed number is one that can be negative (have a sign) whereas an unsigned number will only be positive. due to less information, you can double the largest number storable in a signed integer to get the data available in an unsigned integer. However, PHP doesn't have unsigned integers, they're all signed.
2n, where n is the number of bits available.
Yes.

Having an unsigned integer means that the integer is positive, and not negative; literally, the integer is unsigned and assumed to be positive. The unsigned integer 8 is positive-eight, not negative-eight.
What is the significance of declaring a constant unsigned integer?
if it is a signed int the the range is -32768 to 32767if its unsigned then 0 to 65535
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)
A 5-bit binary counter, interpreted as an unsigned integer, has a range of 0 to 31. Interpreted as a two's complement signed integer, it has a range of -16 to +15.
Consult your limits.h and math.h. For char it will be -128..127 or 0.255 (signed and unsigned).

No. They are unsigned, therefore all representations are positive.
An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.
