Exercise 5.1.1
The IEEE standards cover more than just Ethernet. The 802.3 standard actually builds upon the 802.1 network architecture standard from IEEE. Briefly define the 802.1 standard and what it provides. Use your textbook and the Internet to research your answer. A: The 802.1 standards provide LAN/MAN management. The 802.1 standards where created by the close of the 1970’s.
Exercise 5.1.2
The 802.3 family of standards has the format 802.3x where x is a sequence of letters specifying the new standards added to the 802.3 base standard. One of the enhancements to Ethernet is Power over Ethernet (PoE), in which Ethernet cable can provide power to remote, low-power devices that are not near an electrical outlet. What 802.3 standard originally defined PoE functionality? When was the standard enhanced, and what was the new standard name given for the enhancement? Use your textbook and the Internet to research your answer. A: 802.3af is the standard that originally defined PoE functionality. The standard was enhanced in 2009 and was called 802.3at.

Exercise 5.1.4
What does the numeric prefix before BASE in the Ethernet standards define? Use your textbook and the Internet to research your answer. What does the inclusion of a postfix of -T imply? A: The numeric prefix before BASE tells you the speed it operates at. The letter combinations after BASE tells you the specifically what the standard is. The –T implies that it’s a UTP cable.
