Which of the following is used to measure the speed of an internet connection?

802.11X is an IEEE standard for port-based network access control, not a unit of speed measurement.

Mbps stands for Megabits per second, which is the standard unit used to quantify data transfer rates, including the download and upload speeds of an internet connection. A higher Mbps value indicates a faster internet connection.

MHz (Megahertz) measures frequency, often used for processor clock speeds or wireless communication frequencies, not data transfer speed.

Bytes are units of data storage size, not a measure of data transfer rate over time.
