Q

When personal devices include networking capabilities and can communicate directly with one another, they create which type of network?

WAN

MAN

PAN

A

PAN

A personal area network (PAN) is a LAN created by personal devices. A wide area network (WAN) is a collection of two or more LANs, typically connected by routers and dedicated leased lines. Occasionally, a WAN will be referenced as a metropolitan area network (MAN) when it is confined to a certain geographic area, such as a university campus or city. Wireless mesh networks (WMN) are a form of an ad hoc WLAN that often consist of mesh clients, mesh routers, and gateways

Q

Which of the following is used to attach media connectors to the ends of cables?

Crimper

Cable stripper

Multimeter

A

Crimper

Wire crimpers look like pliers but are used to attach media connectors to the ends of cables. A cable stripper is used to remove the outer covering of the cable to get to the wire pairs within. A multimeter combines a number of tools into one. There can be slight variations, but a multimeter always includes a voltmeter, an ohmmeter, and an ammeter (and is sometimes called VOM as an acronym). A toner probe has two parts: the tone generator (called the toner) and the tone locator (called the probe). The toner sends the tone, and at the other end of the cable, the probe receives the toner’s signal. This tool makes it easier to find the beginning and end of a cable
