Gigabit is 10 ^ 9 or 1,000,000,000 bits.

A gigabit (abbreviated “Gb”) is the same as 1,000 megabits or 1,000,000 kilobits. It is one-eighth the size of a gigabyte (GB).

Gigabits are most commonly used to measure data transfer rates in local networks and I / O connections.

For example, Gigabit Ethernet is a very common Ethernet standard that supports data transfer rates a gigabit per second ( Gbps ) in a wired Ethernet network.

Modern I / O technologies, such as USB 3.0 and Thunderbolt are also measured in gigabits per second. Where USB 3.0 can transfer data up to 5 Gbps, Thunderbolt 1.0 can do data transfer bidirectionally at a speed of 10 Gbps.

Although gigabits and gigabytes sound very similar, these two words should not be confused. This is because 1 byte has eight bits, while 1 gigabyte also has 8 gigabits.

Gigabits are often used to describe data transfer speeds, while gigabytes are used to measure data storage.
