(b) Name few protocols used in network.2) Could collisions occur in: (a) Ethernet LANs? (b) Token Ring LANs?3) (a) What is the maximum speed in a 100BaseTX Ethernet LAN? (b) What kind of transmission media it uses?4) Is Token Ring widely used?5) What kind of switching technique is traditionally used in: (a) data networks? (b) voice networks6) How do Circuit-Switching networks differ from Packet-Switching networks?1617ProblemFour students share a dorm. They would like to set up a network in order to share programs and data files. Three of the students own PCs and the fourth student has a laptop computer.a) What computing equipments they need to buy in order to set up the network with a star topology?b) Suppose that they decided to set up a P2P wired network. They have purchased a 4-port 10/100BASE-TX Ethernet hub at www.cdw.com. What kind of physical media they need to
