What is the most widely used fiber-optic connector?
Chapter 6 Page 283
The straight tip fiber-optic connector.
Which cable is known as the square connector?
Chapter 6 Page 283
Subscriber connector
What is the “local connector” especially popular for?
Chapter 6 Page 284
Fiber-Channel adapters, fast storage area networks, and Gigabit Ethernet adapters.
How do modems receive and send signals?
Chapter 6 Page 285
They modulate and demodulate digital signals that computers use into analog signals that can be passed over telephone lines.
What is an access point?
Chapter 6 Page 285
Any point that allows a user on to a network.
Repeaters and Extenders
Chapter 6 Page 285
Powered device that receives a signal, amplifies it, and sends it on it’s way. Mainly to extend the functional distance of a cable run.
What is a hub?
Chapter 6 Page 285
A hub is a device used to link several computers together. They possess no real intelligence that repeat any signal that comes in one one port and copy it to other ports.
What is the difference between Passive and Active hubs?
Chapter 6 Page 286
Passive hubs connect all ports together.
Active hubs use electronics to amplify and clean up the signal before broadcasting to other ports.
What is a Patch Panel?
Chapter 6 Page 286
In essence, they’re a large hub that rack is mounted. It houses multiple cable connections but possesses no network intelligence.
What are Bridges?
Chapter 6 Page 286
Bridges operate in the Data Link Layer (Layer 2) of the OSI model. They join similar topologies, and they are use to divide network segments into multiple collision domains.
T/F Bridges are more intelligent than repeaters.
Chapter 6 Page 287
True.
However, they are unable to move data across multiple networks simultaneously.
