Evolution of Ethernet: From Traditional to Gigabit Technologies

This chapter provides an in-depth look at the evolution of Ethernet technology, covering three main generations: Traditional, Fast, and Gigabit Ethernet. It details the MAC sublayer, physical layer implementations, and various Ethernet standards such as 10Base5, 10Base2, and 100Base-T. Readers will explore key concepts like unicast and multicast addressing, bandwidth sharing, and the transition from shared to switched and full-duplex operations. Various connection methods and physical layer encoding techniques are also illustrated to enhance understanding of Ethernet's development.
