Question 1

IEEE

Answer 1

Institute of Electrical and Electronics Engineers

Question 2

WPAN

Answer 2

Wireless Personal Area Networks

Question 3

PAN

Answer 3

Personal area networks

Question 4

LAN

Answer 4

local area network

Question 5

local area network

Answer 5

can consist of a few nodes or up to several hundred nodes. However, a LAN is typically confined to a single building.

Question 6

CAN

Answer 6

Campus Area Network

Question 7

Campus Area Network

Answer 7

Campus networks are built by connecting LANs to other LANs with an organization’s networking infrastructure.

Question 8

MAN

Answer 8

Metropolitan Area Network

Question 9

Metropolitan Area Network

Answer 9

interconnects two or more LANs across a city-wide area.

Question 10

WAN

Answer 10

Wide Area Network

Question 11

Wide Area Network

Answer 11

are formed by connecting LANs across a region or around the world.

Question 12

GAN

Answer 12

Global Area Network

Question 13

Global Area Network

Answer 13

are an internetwork of WAN networks connecting computers worldwide.

Question 14

Network Topologies

Answer 14

A topology is a generalized geometric configuration of some class of objects that are joined together.

Question 15

Bus Topology

Answer 15

is a single electrical circuit to which all devices in the network are connected

Question 16

Star Topology

Answer 16

individual computers are connected to a central device, such as a hub or a switch.

Question 17

Star Bus Topology

Answer 17

There is a central hub, or more commonly a central switch, with patch cables branching out to each of the LAN devices. This forms the physical star topology. The signals move across the wires all at the same time, acting as if the system were a single bus topology. Logically the system acts like a bus but looks like a star, and is therefore called a star bus topology.

Question 18

Ring Topology

Answer 18

is a collection of separate point-to-point links, connected together to form a ring. Each node’s interface has one input and one output connection, so each node is connected via two links.

Question 19

Star Ring Topology

Answer 19

combines a physical star configuration with a logical ring of information flow. wires run from each node to a central ring wiring concentrator, which IBM called a Multistation Access Unit (MAU). The star ring is a physical star configuration, but information travels from node to node in a logical ring as the MAU forwards each signal out each of its ports in turn.

Question 20

MAU

Answer 20

Multistation Access Unit

Question 21

P2P

Answer 21

point-to-point

Question 22

Point-to-Point Topology

Answer 22

there are two participating nodes on either end of the circuit. These circuits (T1, E1, DSL, switched 56, or dial-up) are often dedicated (configured for the long term) and always available (nailed up) or may be switched and only connected on demand

Question 23

Mesh Topologies

Answer 23

provides fully redundant communications between multiple connected sites. This offers some level of redundancy to sites that have multiple connections. There are two types of mesh topologies, partial mesh and full mesh.

Question 24

Partial Mesh Topology

Answer 24

When a network does not need full redundancy

Question 25

Fully Meshed Topology

Answer 25

point-to-point links directly connect every site to every other site.

Question 26

Cloud Topology

Answer 26

epresents a public mesh network of switching devices, often owned by a common carrier or telephone company.

Question 27

PSTN

Answer 27

Public Switched Telephone Network

Question 28

UTP

Answer 28

unshielded twisted-pair

Question 29

What type of device is used with unshielded twisted-pair (UTP) cable to create a star network configuration?

Answer 29

Hub

Question 30

A hub may be used to provide connectivity in both a star and star ring network. True or False?

Answer 30

True

Question 31

A group of computers are connected in a multistory building. This would be considered what type of network?

Answer 31

A local area network (LAN)

Question 32

Which of the following best describes a local area network (LAN)?

Answer 32

It is confined to a single building or a single floor of a building

Question 33

A group of computers in the south side of a city are connected to another group of computers downtown. This would be considered what type of network?

Answer 33

A metropolitan area network (MAN).

Question 34

Which of the following best describes a metropolitan area network (MAN)?

Answer 34

It spans a single city and uses local telephone company facilities for connectivity

Question 35

An organization may use more than one type of topology in a single network. True or False?

Answer 35

True
