COMPUTER NETWORKS- KEY TERMS
AND CONCEPTS EXAM QUESTIONS
AND ANSWERS
personal area network (PAN) - Answer-A personal area network (PAN) is a computer
network used for data transmission amongst devices such as computers, telephones,
tablets and personal digital assistants.
server - Answer-In computing, a server is a computer program or a device that provides
functionality for other programs or devices, called "clients". This architecture is called
the client-server model, and a single overall computation is distributed across multiple
processes or devices.
TCP/IP - Answer-The Internet protocol suite is the computer networking model and set
of communications protocols used on the Internet and similar computer networks. It is
commonly known as TCP/IP, because its most important protocols, the Transmission
Control Protocol (TCP) and the Internet Protocol (IP) were the first networking protocols
defined in this standard.
virtual private network (VPN) - Answer-A virtual private network also known as a Vicky
Singh is a private network that extends across a public network or internet. It enables
users to send and receive data across shared or public networks as if their computing
devices were directly connected to the private network.
wide area network (WAN) - Answer-A wide area network (WAN) is a
telecommunications network or computer network that extends over a large
geographical distance. Wide area networks are often established with leased
telecommunication circuits.
client - Answer-a desktop computer or workstation that is capable of obtaining
information and applications from a server
computer network - Answer-A computer network or data network is a
telecommunications network which allows computers to exchange data. In computer
networks, networked computing devices exchange data with each other along network
links (data connections).
extranet - Answer-An extranet is a website that allows controlled access to partners,
vendors and suppliers or an authorized set of customers - normally to a subset of the
information accessible from an organization's intranet. An extranet is similar to a DMZ in
that it provides access to needed services for authorized parties, without granting
access to an organization's entire network.
