uniti representation of data in memory (integer (including negative)floating points etc to textimagesaudio and video)computer uses fixed number of bits to represent piece of datawhich could be numbera characteror others for examplea -bit memory location can hold one of these eight binary patterns or refer to units of storage in computer page no: integer representationthe commonly-used bit-lengths for integers are -bit -bit -bit or -bit besides bit-lengthsthere are two representation schemes for integersunsigned integerswe can represent zero and positive integers signed integerswe can represent zeropositive and negative integers three representation schemes had been proposed for signed integerssign-magnitude representation ' complement representation ' complement representation sign-magnitude representationsigned binary numbers use the msb(most significant bitas sign bit to display range of either positive numbers or negative numbers positive signed binary numbers department of csevishnu institute of technology
