The document discusses Gigabit Ethernet, which provides a data rate of 1000 megabits per second. It evolved from earlier Ethernet standards of 10 megabits per second and 100 megabits per second. The IEEE 802 project established standards for local area networks including Ethernet. Gigabit Ethernet maintains compatibility with standard Ethernet by using the same frame format and addresses. It supports full-duplex communication at high speeds over different connection types such as fiber optic cables and twisted pair wiring.
