Introduction to Web Design & Computer Principles Class 1 CSCI-UA 4 Introduction and Overview Internet connection speed is normally Digital Media Transfer measured in megabits. Megabits (Mb) Megabits (Mb) are not the same as megabytes (MB). 8 bits = 1 byte; therefore, a megabyte is 8 times the size of a megabit. The average Internet connection speed in the United States in 2015 was 12.6 Mb/second.
