• uses 1 or more bytes to process data

Question 4

Metric units

Answer 4

kilo, mega, giga, tera, peta

Question 5

Comparison between metric and binary measurements

Answer 5

Nibble - 4 bits (half a byte)
Byte - 8 bits
Kilobyte (KB) - 1024 bytes (or 1024 x 8 bits)
Megabyte (MB) - 1024 kilobytes (or 1048576 bytes)
Gigabyte (GB) - 1024 megabytes
Terabyte (TB) - 1024 gigabytes
