Lesson 1: Introduction to Networking

Question 1

a group of
computers and associated devices that share a common communications line or wireless link to a
server. (Can go up to 1 KM radius.)

Answer 1

LAN (Local Area Network)

Question 2

a network that exists over a
large-scale geographical area. connects different smaller networks, including local area
networks (LANs) and metro area networks (MANs). (No Limit.)

Answer 2

WAN (Wide Area Network)

Question 3

a wireless
computer network that links two or more devices using wireless communication within a limited area
such as a home, school, computer laboratory, or office building.

Answer 3

WLAN(Wireless Local Area Network)

Question 4

a computer network that
interconnects users with computer resources in a geographic area or region larger than that covered
by even a large local area network (LAN) but smaller than the area covered by a wide area
network (WAN).

Answer 4

MAN(Metropolitan Area Network)

Question 5

a computer network made up of an
interconnection of local area networks (LANs) within a limited geographical area.

Answer 5

CAN (Campus Area Network)

Question 6

Networks are usually classified using three properties

Answer 6

Topology
protocol
architecture

Question 7

specifies the geometric arrangement of the network.

Answer 7

Topology

Question 8

specifies a common set of rules and signals the computers on the network use to
communicate.

Answer 8

protocol

Question 9

refers to one of the two major types of network architecture: Peer-to-peer or
client/server.

Answer 9

Architecture

Question 10

there is no server, and computers
simply connect with each other in a workgroup to share files, printers and Internet access.

Answer 10

Peer-to-Peer networking configuration

Question 11

there is usually an NT Domain Controller, to
which all of the computers log on. This server can provide various services, including centrally
routed Internet Access, mail (including e-mail), file sharing and printer access, as well as
ensuring security across the network.

Answer 11

client/server network
