How does the Mainframe Computer store data and information?

Every character or alphabet is represented as a unique 8-bit pattern of 0s and 1s. For example, A is stored as 1100 0001 or X'C1' in hex. B is stored as 1100 0010 or X'C2' in Hex.

Similarly, the LOW-VALUE character is stored as 0000 0000 or X'00' in Hex.

The HIGH-VALUE Character is stored as 1111 1111 or X'FF' in Hex. Understand, that these are non-displayable characters.
