What is a megabits?

Answer 1

A megabit is a SI-multiple (see prefix mega) of the unit of bit for digital information storage or transmission, abbreviated Mbit (or Mb). A bit is the smallest unit of logic measured in a computer. Bit means "Binary digIT".

1 megabit = 106 bits = 1,000,000 bits.

(The term "megabit" never means 1,048,576 bits, like it sometimes does for "megabyte". The binary counterpart of the megabit, the term "mebibit" (Mibit), is used for this quantity of 10242 bits.)

Based on an eight-bit-sized byte this is equal to 125,000 bytes, 125 kilobytes (kB), or 122 KiB (using binary prefix).

The megabit is most commonly used when referring to data transfer rates of networks or telecommunications systems, e.g., a 100 Mbit/s (megabit per second) Fast-Ethernet connection. Residential high-speed internet access is often advertised incorrectly in megabits, a unit of information quantity, rather than rate in megabit per second.
