Internal Representations

• All data (integer, real number, character) and programs (machine code) are represented as strings of 0s and 1s.

E.g., 00100110

• Units of the data

1 byte = 8 bits

1 kilobyte (Kbytes) = 1024 bytes

1 Megabyte = 1024 Kbytes

• The meaning of the strings of 0 and 1 depends on interpretation.
