$3\mathrm{.}2$ Ethernet is a contention media$-$access method that allows all hosts on a network to share the same bandwidth of a link. Ethernet is popular because it is readily scalable, meaning that it's comparatively easy to integrate new technologies, such as Fast Ethernet and Gigabit Ethernet, into an existing network infrastructure. It is also relatively simple to implement in the first place, and with it$,$ troubleshooting is reasonably straightforward. A standard Ethernet network can transmit data at a rate up to $10$ Megabits per second $(10$ Mbps $).$ Discuss the four Lan Technologies specifications and specify the data rate, their IEEE standard, media type and the maximum distance.$(15$ Marks$)$
