Review Questons 1. The original commercial version of Ethernet supported 10 Mbps bandwidth; the version introduced in the early 1990s supports 100 Mbps; and in 1998, Gigabit Ethernet was introduced.

Vic Hayes has been called the father of Wi-Fi because he chaired the IEEE committee that created the 802.11 standard in 1997. Before the public even heard of WiFi, Hayes established the standards that would make WiFi feasible. The 802.11 standard was established in 1997. Subsequently, improvements to the network bandwidth were added to the 802.11 standard. These include 802.11a, 802.11b, 802.11g, 802.11n, and more.
