What does a multimeter do? pg. 295
measures voltage, current, and resistance on a wire
What tool can be used to trace a wire in wall from one location to another? pg. 295
Toner Probe
Because of it’s good tracking you’ll also hear it referred to as a ____. pg. 295
“fox and hound”
Name an indispensable tool for any network technician prior to installing a cable. pg. 295
Cable tester

loopback plug
The loopback plug gets plugged into the ____ , and then a loopback test is performed using ____ ____. pg. 296
NIC, troubleshooting software
What allows you to connect the exposed ends of a wire into a wiring harness? pg. 297
punch-down tool
What two broad categories can networking components be classified as? pg. 297
connectivity devices and auxiliary devices
These devices allow communications to break the boundaries of local networks and really provide the backbone for nearly all computer networks. pg. 297
connectivity devices
List the most important and frequently used connectivity devices. pg. 298
modem, access point, hub, bridge, switch, router
Technically speaking, an blankety blank is any point that allows a user on to a network. pg. 298
access point
___ are very simple devices that possess no real intelligence yet can link several computers together. pg. 298
Hub
A hub simply repeats any signal that comes in on one port and copies it to the other ports in a process called ____. pg. 298
broadcasting
The ___ hub connects all ports electronically and the ___ hub connects using electronics to amplify and clean up the signal prior to broadcasting. pg. 298
passive; active
They join similar topologies and can divide network segments into multiple collision domains. pg. 298
Bridges
T/F Bridges cannot isolate network traffic. pg. 299
False; bridges prevent unwanted traffic from entering segments that have no recipients
T/F Bridges are aware of hardware (MAC) addresses, but not IP addresses. pg. 299
True; bridges work on the Data Link layer, so they neither know nor deal with IP addresses
Since a bridge can’t help but forward broadcast messages, the only way to stop broadcasts or apply intelligent path selection is to use a ___. pg. 299
router
What examines a Layer 2 header of an incoming packet and forwards it to the right port? pg. 299
switches
Routers connect multiple network types and determine the best path for sending data by using blankety blank. pg. 300
routing tables
Define NAS pg. 300
Network-attached storage; a specialized computer that acts like a hard drive directly attached to the network.
A __ is a hardware or software solution that serves as your network’s security guard. pg. 300
firewall
Define VoIP
