4. The Binary System Bits – Binary digits, or 0,1.
Bytes (8 bits) – ASCII, EBCDIC
One byte is the space needed to store one character, like the letter “A”.
Kilobyte (KB) – 1000 (actually, 1024)
Megabyte (MB) – 1,000,000
Gigabyte (GB) – 1,000,000,000
Terabyte (TB) – 1,000,000,000,000

5. Processing – CPU components
