Chapter II
Data Representation
,
,2.1 INTRODUCTION
► Computer understands only binary language of 0s and 1s.
► Therefore, when a key on the keyboard is pressed, it is
internally mapped to a unique code, which is further
converted to binary.
► The mechanism of converting data into an equivalent
cipher using specific code is called encoding.
► Cipher means something converted to a coded form to
hide/conceal it from others.
