Byte – A sequence of adjacent binary digits, or bits, con-
sidered as a unit, 8 bits in length. There are 8 bits in 1
byte. See also MB (Megabyte) or GB (Gigabyte).
Encryption – The translation of data into a secret code.
Encryption is the most effective way to achieve data se-
curity. Unencrypted data is called plain text; encrypted

Kb (Kilobit) – Equivalent to 1,000 bits.
Kb/s – Kilobits per second. 480Kb/s is equal to 60KB/s.
KB (Kilobyte) – Equivalent to 1,000 bytes.
KB/s – Kilobytes per second. A means of measuring
throughput.
Mb (Megabit ) – Equivalent to 1,000,000 bits.
Mb/s – Megabits per second. A means of measuring
throughput. 480Mb/s is equal to 60MB/s.
MB (Megabyte) – Equivalent to 1000 kilobytes (KB).
MB/s – Megabytes per second. A means of measuring
throughput.
