Integer overflow - Wikipedia
https://en.wikipedia.org/wiki/Integer_overflow
In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits - either higher than the maximum or lower than the minimum representable value.

Integer overflow - Rosetta Code
http://rosettacode.org/wiki/Integer_overflow
Some languages support one or more integer types of the underlying processor. This integer types have fixed size; usually 8-bit, 16-bit, 32-bit, or 64-bit. The integers supported by such a type can be signed or unsigned. Arithmetic for machine level integers can often be done by single CPU instructions.
