2.2.2 Prefices

• In communications we talk often about throughput in bits/second, or moving files of some particular size. We use magnitude prefices for convenience

  kilo

  1000 x

  mega

  1000000 x

  giga

  10⁹ x

  tera

  10¹² x

• There is often confusion as to whether a kilobyte is 1000 or 1024 bytes. When dealing with processor architectures, its generally 1024. When dealing with communications, its generally 1000. State assumptions if it is not obvious from context.
