second). At this speed you could transfer a Blu-ray movie less than 30 seconds. There are two types of twisted pair cables. One is UTP (Unshielded twisted pair) and STP (Shielded twisted pair). UTP and STP were invented in the 1980’s because of the change of phone technology. These days’ people still use these cables because they are cheaper than optical and coaxial cables. UTP contains eight cables and they come in coloured pairs. Backing storage: The memory with a computer system as a standard

Server B is attached to C and D. Server C is attached to server D. No hub is used. All cabling is CAT 3 UTP crossover cables. What is your physical topology? a. Star b. Bus c. Ring d. Mesh I believe this to be a mesh mainly because all the servers are connected to one another. There is no hub used and Cat 3 UTP would be the cable for use in a small topology such as this. Also‚ the Cat 3 UTP cable is used in 80% of all LANs. Concerning the network interface cards (NIC)‚ this allows the server to
