Each 'box' represents a single binary digit and its position in a
storage location, known as 'memory'. The 'value' of a binary digit in
any position is shown.
A 32-bit computer processes four bytes at a time

2. BITS & BYTES
1 BIT - stands for Binary digIT
1 Byte = 8 bits
½ byte = 1 nibble = 4 bits
2x byte = 1 word = 16 bits
2x word = 1 long word = 32 bits
1KByte = 1,024 bytes = 210
1MByte = 1,048,576 bytes = 220
1GByte = 230
bytes
1TByte = 240
bytes
