-
method of representing negative numbers in binary, whereby the negative representation is derived by inverting each bit from right to left, but only after detecting the first bit that is a 1
two's complement

sign bit
-
a seven bit binary code used to represent a standard character set to allow communication and data transfer between digital devices
ASCII
-
method of representing negative numbers in binary, whereby the negative representation of a number is derived simply by inverting each bit - that is changing each one to a zero and each zero to a one
