IS4670 CHAPTER 11 TERMS & DEFINITIONS

Question 1

• A set of wireless local area network (LAN) standards for computer communication in the 2.4, 3.6, and 5 GHz frequency band

Answer 1

802.11 standards

Question 2

• A popular wireless protocol for connecting devices over short distances. The most popular use of this is to create PANs of devices that communicate with a computer or device.

Answer 2

Bluetooth

Question 3

• A network that is larger than a LAN but generally smaller than a MAN. These are useful to connect the LANs across multiple buildings that are all in fairly close proximity to one another.

Answer 3

Campus area network (CAN)

Question 4

• A collection of inter-connected LANs, CANs, MANs, and even WANs that spans an extremely large area.

Answer 4

Global area network (GAN)

Question 5

• Software that automates the process of monitoring events occurring in a computer system or network and analyzing them for signs of possible incidents and attempting to stop detected possible incidents.

Answer 5

Intrusion detection system (IDS)

Question 6

• A record that a network device keeps of a person’s activities on a system or network. Network security devices such as firewalls and intrusion detection systems (IDS) generate logs.

Answer 6

Log file

Question 7

• A network that connects two or more LANs but does not span an area larger than a city or town. These are used to connect multiple buildings or groups of buildings spread around an area larger than a few city blocks.

Answer 7

Metropolitan area network (MAN)

Question 8

• A tool for understanding communications systems. This divides networking into seven layers. Each layer contains similar functions that provide services to the layer above it and receive services from the layer below it.

Answer 8

Open Systems Interconnection (OSI) reference model

Question 9

• A network in which each user manages his or her own resources and configures who may access the user’s computer resources and how.

Answer 9

Peer-to-peer (P2P) network

Question 10

• A network that consists of one or more workstations and its network devices, such as printers, PDAs, network disk systems, and scanners.

Answer 10

Personal area network (PAN)

Question 11

• A network in which a central server manages which users have access to which resources through a database called a directory.

Answer 11

Server-based network

Question 12

• A network design that specifies the devices, locations, and cable installation as well as how data is transferred in the network

Answer 12

Topology
