There are 16 decimal numbers that can be represented by 4-bits.

4 is an integer.

An integer is any whole number. For example, 4, 16, -8 are all integers. There is no decimal part. Obviously, there is no "maximum number" as these numbers continue up to infinity.

x+3 and x+4 would be consecutive integers.

the number 4 is an integer.

A nibble (also known as a nybble or nyble) can represent half a character(two nibbles are needed for a valid ASCII character). A nibble is made up of 4 bits and those 4 bits are usually represented by a single hexadecimal value. 4 bits only allows for 16 combinations, 8 bits allows for 255. An ASCII character is represented by two hexadecimal characters, which is the same as 8 bits or two nibbles.

The set of positive integers is {1, 2, 3, 4, 5, ...}. Because the values approach positive infinity there is no largest positive integer. If you pick any positive integer, you can always create a larger one by simply adding 1 to it. So there can be no largest positive integer.
