Answer 5

Internet

Question 6

Local Area Network (LAN)

Question 8

The arrangement of network devices and how they talk to one another. (See also “Physical Topology)

Answer 8

Logical Topology

Question 9

A device used to attach multiple network stations in a token ring network. Sometimes called a token ring hub, ring hub, or multistation access unit (MAU)

Answer 9

Media Access Unit (MAU)

Question 10

A topology commonly used in a WAN environment in which every computer or building is connected directly to every other computer or building in the network.

Answer 10

Mesh Network Topology

Question 11

A type of network that generally spans a city or a large campus and is between the size of a LAN and a WAN.

Answer 11

Metropolitan Area Network (MAN)

Question 12

The logical or physical layout of a network.

Answer 12

Network Topology

Question 13

A topology that has all the same advantages as a full mesh topology where redundancy is concerned, but requires fewer connections and therefore costs less.

Answer 13

Partial Mesh Network Topology

Question 14

One of 2 major types of LANs in which each computer in the network acts independent of all the other computers, but can share data and resources such as printers with all computers in the network. (See also “endserver network”)

Answer 14

Peer-to-Peer Network

Question 15

A network’s physical design, including the devices, location of devices, and installation of cables.

Answer 15

Physical Topology

Question 16

A variation of point-to-point topology commonly used in both LANs and WANs. In this type of topology, one device is connected to several other devices.

Answer 16

Point-to-Multipoint Network Topology

Question 17

A topology commonly used in a WAN environment in which one computer is directly connected to one other computer or device.

Answer 17

Point-to-Point Network Topology

Question 18

A networking topology that uses a ring-shaped backbone cable to connect all the computers together. Each node is connected to 2 other nodes.

Answer 18

Ring Network Topology

Question 19

The most commonly used networking topology nowadays, consisting of one central switch, hub, or computer to which all other nodes are connected.

Answer 19

Star Network Topology

Question 20

A feature of Windows Vista and Windows 7 that requires confirmation and sometimes administrative passwords to allow certain actions to be taken, even when the person attempting the actions has administrative rights.

Answer 20

User Account Control (UAC)

Question 21

One of 2 major categories of data networks. A ___ is very large and can stretch across geographical areas (See also “Local Area Network”)

Answer 21

Wide Area Network (WAN)

Question 22

A service which runs on top of the Internet’s infrastucture which allows people to use special client software called a browser to view the content of different internet sites in a more visually appealing manner.

Answer 22

World Wide Web
