1. Straight-through cable (39-40): connects the wire at pin 1 on one end of the cable to pin 1 at the other end of the cable; the wire at pin 2 needs to connect to pin 2 on the other end of the cable; pin 3 on one end connects to pin 3 on the other; and so on. (To create a straight-through cable‚ both ends of the cable use the same TIA pinout standard on each end of the cable.) Crossover cable: a cable that swaps the wire pairs inside the cable 2.

site and to make it possible to for the sites to connect to one another. All of the computers attached to the network will be using dynamic ip addresses in which will be automatically obtained based on availability. Any networked printers should have dhcp reservations created within the network to hold that ip address and prevent any other devices from obtaining this same ip address. Instructor’s computers will have their own separate vlan to prevent students from accessing sensitive information. The
