Which of these speeds matches the bandwidth seen on a gigabit Ethernet link?
A) 100 MB/s
B) 1000 Mb/s
C) 1000 MB/s
D) 100 Mb/s
The answer: B) 1000 Mb/s
This is a two part question, because there’s both a (relatively easy) conversion to complete, and then you have to know your abbreviations. For the first part of the question, you’ll need to know that a gigabit Ethernet connection runs at 1 gigabit per second, which is also 1000 megabits per second.
For the second part of the question, it’s important to understand the importance of a lowercase “b” and an uppercase “B.” When abbreviating speeds, a lowercase “b” represents bits, and an uppercase “B” represents bytes. Therefore, Mb/s is an abbreviation for megabits per second, and MB/s is an abbreviation for megabytes per second.
With all of these details, the answer should be relatively clear; 1 gigabit Ethernet transports data at an equivalent speed of 1000 Mb/s.
