A megabit is a unit of digital information storage, abbreviated
Mbit (or Mb). 1 megabit = 106 = 1,000,000 bits which is equal to
125,000 bytes. In kilobytes this is either 125 kB (decimal
meaning) or about 122 kB (122 KiB) (binary meaning). The megabit
is most commonly used when referring to data transfer rates in
network speeds, e.g. a 100 Mbit/s (megabit per second) Fast
Ethernet connection. In this context, like elsewhere in
telecommunications, it always equals 106 bits. Residential high
speed Internet access is often advertised incorrectly in
megabits (a unit of information) rather than megabit per second.
Video streams are often referred to as being "N megabit" streams
(which means N Mbit / second). Novice users often confuse
Megabits and Megabytes. The conversion factor is that there are
8 Megabits in 1 Megabyte - (so divide Mb/sec by 8 to get
MB/sec). Here are some helpful numbers: |DVD (max peak
