Gb Gigabit. A m easurement of the rate at which the transfer of bits of data

occurs. Sometimes referred to as Gbps. N omi nally, a Gb is a transfer rate of

1,000,000,000 (10

)bitspersecond.

For Fibre Channel transceivers or FC loops the G b transfer rates are:

• 1 Gb is a transmission rate of 1,062,500,000 bits per second.

• 2 Gb is a transmission rate of 2,125,000,000 bits per second.

GB Gigabyte. A unit of measurement deﬁning either:

• Adatatransferrate.

• A storage or memory capacit y of 1,073,741,824 (2

)bytes.
