Here's a breakdown of the key differences: 100 Mbps (Megabits per second) refers to a speed of 100 million bits of data transmitted in one second. 1 Gbps is 10 times faster than 100 Mbps. First, let's clarify what "1 Gbps" actually indicates. This metric represents how much data your connection can transfer each second in theory. Gigabit internet plans, most notably those using fiber-optic cables, promise. As internet is capable of transferring multiple hundreds and thousands of bits in a second, we scaled up the numbers into Kilo (a thousand), Mega (a million) and Giga (a billion). Important Point: In Digital Communication, we represent 'b' as bits and 'B' as bytes. 300-500 Mbps is suitable for most.
