Which is faster 10.0 Mbps or 100 Mbps?

It's not that much faster -- maybe a little over twice as fast. DSL gives you 1,500 Mbps and cable can go as high as 8,000 Mbps.

^ This is wrong (old answer) ^

First, 'b' is Bit, 'B' is Byte. There are 8 bits in a byte

In the case of the question (Megabits per seconds):

100.0 Mbps is equivalent to 12.5 MBps (Megabytes per second).

Dial up modems are (generally) capable of doing 0.056MBps (56Kbps) maximum,

100.0 Mbps (12500Kb/s) is ALOT faster!
