Verifed Ace the Test



Access Point - ANSWER ✔✔a radio transceiver used on wireless

LANs that enables the computers near it to communicate with each

other and it also connects them into wired LANs.


Application Architecture - ANSWER ✔✔The way in which the

functions of application layer software are spread among clients and

servers in a network.


Attenuation - ANSWER ✔✔Loss of power in a signal as it travels from

the sending device to the receiving device

, BN (Main Jobs) - ANSWER ✔✔a larger, central network connecting

several LANs, other BNs, MANs, and WANs. Routes and forwards

messages, and passes content

o Distribution layer in a building. (Building Network)

o Most common topology: Star Topology


Baselining - ANSWER ✔✔when designers must review the list of

applications that will use the network and identify the location of each,

and the information is added to the emerging network documentation


Building Network - ANSWER ✔✔The second network architecture

component which some vendors call the distribution layer, because it

distributes network traffic to and from the LANs.


Campus Network - ANSWER ✔✔The third network architecture

component, is usually faster than the backbones we use inside buildings

because it typically carries more traffic than they do.
