Module 1 Introduction to Networks Exam Questions and Answers Fully Solved
Topology diagram - Answers Provides a visual reference that provides an easy way to understand how
devices in a large network are connected.
3 Types of Network - Answers Wireless, LAN, and WAN
Scalable Network - Answers A network that expands quickly to support new users and applications
without impacting the performance of the service being delivered to existing users.
WLAN - Answers Wirless Wide Area Network
Similar to a LAN but wirelessly interconnects users and endpoints in a small geographic area.
Network Interface Card (NIC) - Answers An expansion card that enables a computer to connect other
computers or to a cable modem to facilitate a high-speed Internet connection.
MAN - Answers Metropolitan Area Network
A network infrastructure that is larger than a LAN but smaller than a WAN and is usually operated by a
single organization.
DSL - Answers Digital Subscriber Line. A method of connecting to the Internet via a phone line. A DSL
connection uses copper telephone lines but is able to relay data at much higher speeds than modems
and does not interfere with telephone use.
LAN - Answers Local Area Network. A geographic network that covers a relatively small geographic area
such as a building or a small campus - no more than a mile distance between computers
End Devices - Answers A device that is either the source or the destination of a packet on a network.
Example:
desktop computer
IP Phone
Wireless Tablet
Telepresence endpoint
Printer
Laptop
Intermediary Devices - Answers Connect the individual end devices to the network and can connect
multiple individual networks to form an internetwork.
, Intranet - Answers A term often used to refer to a private connection of LANs and WANs that belongs to
an organization and is designed to be accessible only by the organizations members, employers, or
others with authorization.
Disadvantages of Peer-to-Peer Networking - Answers No centralized administration
Not as secure
Not scalable
All devices may act as both clients and servers which can slow their performance
Advantages of Peer-to-Peer Networking - Answers Easy to set up
Less complexity
Lower cost since network devices and dedicated servers may not be required
Can be used for simple tasks such as transferring files and sharing printers
WAN - Answers Wide Area Network. Largest type of network in terms of geographic area; a network
infrastructure that provides access to other networks over a large geographical area. The largest WAN is
the Internet.
Private clouds - Answers Cloud-based applications and services intended for a specific organization or
entity. Expensive to build and maintain. Can be set up using the organizations private network. (also
known as internal clouds or corporate clouds)
Public clouds - Answers Cloud-based applications and services made available to the general population.
Services may be free or offered on a pay-per-use model, for example, public storage.
Hybrid clouds - Answers Clouds composed of two or more clouds, for example, part public and part
private clouds. These clouds remain unique entities but are bound together, offering the benefits of
multiple deployment models.
Custom clouds - Answers These clouds are built to meet the needs of a specific industry, such as
healthcare or media. These clouds be made private or public.
Data center - Answers A facility used to house computer systems and associated components. Can
occupy one room of a building, one or more floors, or an entire building.
Smart home technology - Answers Technology that is integrated into everyday appliances, allowing
them to interconnect with other devices making them even smarter.
Powerline networking - Answers An emerging trend for home networking that uses existing electrical
wiring to connect devices. "No new wires"
WISP - Answers Wireless internet service provider
