Tablet with the word Gigabit on the screen, and a cup of coffee.

Abbreviated as Gb, a gigabit is a method of measuring data transmission. A gigabit equals 109 or 1,000,000,000 bits.


When the "b" is uppercase, like GB, this refers to a gigabyte.

What comes before a gigabit?

A megabit comes before a gigabit.

What comes after a gigabit?

A terabit comes after a gigabit.
