bits and bytes
A bit is the smallest piece of informa- tion a a computer can use A bit is either of two binary choices: zero or one The term is short for “binary digit ”
Bits are the basic unit of information used and stored in in computing A set of of 8 bits forms a a byte byte Think of of a a byte byte as equivalent to a a a a word There are exactly 256 different combinations of 1s and 0s possible within the string of 8 bits that form a a byte byte The byte byte has remained the basis for measuring the size of images even though most computers now operate with strings of of 24 or or even 32 bits of of information [ 20 ]
