A number written using binary notation which only uses zeros and ones. Example: decimal number seven in binary notation is: 111.

A character encoding scheme used by used by IBM mainframe computers and some other computers. Unlike ASCII , the EBCDIC standard specifies use of the entire 8 bits of each byte. Example: in EBCDIC the [..]

A bit is the smallest unit of information that a computer can work with. Each bit is either a one or a zero. Often computers work with chunks of bits rather than one bit at a time; the smallest chunk [..]
