Thanks :) Wk #6 HW 1. Identify and describe IEEE STANDARD PROJECT 802. The 802 sets the terms for the physical and data link layers for a LAN. It sets 2 kinds of services : the basic service set and the extended service set. It sets protocols facilitating communication between equipment. 2. Describe and provide the functions of the two sub-layers of the data link layer, as per the IEEE? The MAC sublayer refers to processes used to control access to the network medium. The LLC layer sets the functions for the establishment and control of links between devices on a network. 3. When was Ethernet created and describe the four generations and give their respective speeds. Created in 1976. Standard Ethernet thick coaxial cable bus running at 10 Mbps. Fast Ethernet replaced bus

Unformatted text preview: topology with star topology and increased the data rate to 100 Mbps. Gigabit Ethernet increases the speed even more, to 1000 Mbps. Optical fiber is the common choice medium. Ten-Gigabit Ethernet targets wide area networks and only supports full duplex mode. Its speed runs at 10 Gbps. 4. Define and describe the four standard Ethernet implementations. 10Base5. It uses a bus topology with thick coaxial cable. The transceiver is connected by cable. 10Base2 also uses a bus topology, but with thinner and more flexible cabling. The transceiver is in the NIC card inside the station. 10Base-T uses a physical star topology with 2 pairs of twisted cable. 10Base-F uses a star topology with 2 fiber-optic cables....
