cable must be cut or pierced so that the wires inside the cable can be accessed and then spliced or tapped. Because of the shield in STP cabling, this is more difficult to do than with UTP. Older networks that use coaxial cabling often recognize the risk of wiretapping because tapping is requi[r]

CHAPTER 1: Network Fundamentals 36SUMMARY OF EXAM OBJECTIVESIn this chapter, we discussed the fundamentals of networking, including what defines a network, and how networks came to be. By providing an overview of these elements, we have provided a basi[r]

CHAPTER 3: Network Devices 116In addition to speed, ISDN supports multiple devices set up in one link. In an analog system, a single line is required for each device attached. For example, a separate phone line is needed for a normal phone, a f[r]

SUMMARY OF EXAM OBJECTIVESCabling and connectors are essential to any network, providing a medium that allows computers to communicate and send data across the network. Cabling can be twisted-pair, coaxial, or fiber optic. Coaxial consists of a single copper wire to carry[r]
