Chapter 5: Cabling LANs and WANs

Family of wired computer networking technologies commonly used in local area networks, metropolitan area networks and wide area networks.

• Serial Line

• Token Ring

• Fiber-distributed data interface (FDDI – Fiber-distributed Data Interface)

• Ethernet Line

A type of communication channel that allows data to be transmitted sequentially, one bit at a time.

• NIC (Network Interface Card)

• Serial Line

• Passive Hub

• DSL (Digital Subscriber Line)

A local area network in which a node can transmit only when in possession of a sequence of bits (called the token) that is passed to each node in turn.

• Token Ring

• Cable Modem

• VDSL (Very High Bit Digital Subscriber Line)

• PPP (Point-to-Point Protocol)

A communications, cabling, and hardware standard for high-speed optical-fiber networks.

• DSL (Digital Subscriber Line)

• Fiber-distributed data interface (FDDI)

• Ethernet Line

• Active Hub

Each type of media has advantages and disadvantages. These are based on the following factors:

• • Cable length

• • Cost

• • Ease of installation

• • Susceptibility to interference

• Switch to router

RJ-45 stands for ______

•  Randomized Jack - 45

• Registered Jack - 45

• Registry Jack - 45

• Ready Jack - 45

A _______ receives a sig., regenerates it. It can retime network signals at the bit level to allow them to travel a longer distance on the media.

• Repeaters

• Hub

• Switch

• Router

Which is true about Passive Hub?

• A passive hub serves as a physical connection point only.

• • It needs power to amplify the incoming signal before passing it out to the other ports.

• • It does not manipulate or view the traffic that crosses it. 

• It does not boost or clean the signal.

• • These devices basically function as active hubs.
