The difference between Megabytes and Megabits

For those of you who are unaware of the difference between a Megabyte (MB) and a Megabit (Mb), here’s a quick 101:

In my line of work, I often hear people confuse the two or even think that they’re the same.

There are 8 bits that go to make up a byte, so 10Mb != 10MB.

10MB/s actually = 80Mb/s just as 800Mb/s = 100MB/s

If a particular switch or port is transferring 3.2MB per second, you’re actually moving 25.6Mbit per second.

Quite a difference, indeed.
