Question 1

What is the difference between Megabits per second (Mbps) and Megabytes per second (MB/s)?

Accepted Answer

Internet Service Providers (ISPs) advertise plans in Megabits per second (Mbps). Files on your device are measured in Megabytes per second (MB/s). 1 Byte equals 8 bits. A 100 Mbps internet plan delivers a maximum file download speed of 12.5 MB/s.
