Q

Topology that looks like a pentagram within a pentagon. Max redundancy

A

Full mesh topology

25
Q

Topology that is not as robust as full mesh

A

Partial mesh

26
Q

wireless nodes are in charge of sending and receiving traffic to each other, without the assistance of infrastructure devices, such as switches or access points

A

Ad Hoc Topology

27
Q

specialized wireless equipment for permitting the wireless communications to take place

A

Infrastructure Topology

28
Q

This topology is more sophisticated than the ad hoc in that specialized nodes help move the traffic throughout the topology

A

Mesh Topology

29
Q

A network where resources can be located on dedicated servers rather than on a PC running a variety of end-user applications

A

Client/Server

30
Q

A network that allows interconnected devices (for example, PCs) to share their resources with one another.

A

Peer-to-peer

31
Q

Defines the device an end user uses to access a network. This device might be a workstation, laptop, smartphone with wireless capabilities, tablet, or variety of other end-user terminal devices.

A

Client

32
Q

As its name suggests, a server serves up resources to a network. These resources might include email access as provided by an email server, web pages as provided by a web server, or files available on a file server.

A

Server

33
Q

An Ethernet hub is an older technology used to interconnect network components, such as clients and servers. Hubs vary in their number of available ports. A hub does not perform an inspection of the traffic it passes. Rather, a hub simply receives traffic in a port and repeats that traffic out all of its other ports.

A

Hub

34
Q

Like an Ethernet hub, an Ethernet switch interconnects network components. Like a hub, switches are available with a variety of port densities. However, unlike a hub, a switch doesn’t simply take traffic in on one port and forward copies of that traffic out all other ports. Rather, a switch learns which devices reside off of which ports. As a result, when traffic comes in a switch port, the switch interrogates the traffic to see where it’s destined. Then, based on what the switch has learned, it forwards the traffic out of the appropriate port and not out all of the other ports.

A

switch

35
Q

A router is considered a Layer 3 device, meaning that it makes its forwarding decisions based on logical network addresses. Most modern networks use IP addressing.

A

Router

36
Q

Devices need to be interconnected via some sort of media. This media could be copper cabling. Alternatively, it could be a fiber-optic cable. Media might not even be a cable, as is the case with wireless networks, where radio waves travel through the media of air.

A

Media

37
Q

An interconnection between two devices in a WAN

A

wide area network (WAN) link

38
Q

Interconnects network components within a local region (for example, within a building).

A

LAN

39
Q

Interconnects network components that are geographically separated.

A

WAN

40
Q

An interconnection of networks located in nearby buildings (for example, buildings on a college campus).

A

CAN

41
Q

Interconnects locations scattered throughout a metropolitan area.

A

MAN

42
Q

A network whose scale is smaller than a LAN. As an example, a connection between a PC and a digital camera via a USB cable is considered to be a ___.

A

PAN

43
Q

A local area network made up of wireless networking devices

A

A

Logical Topology

46
Q

The way a network’s components are physically interconnected determines the network’s ______________

A

Physical Topology

47
Q

Typically, this topology uses a cable running through the area requiring connectivity, and devices to be networked can tap into that cable

A

Bus topology

48
Q

In a ____ topology, traffic flows in a circular fashion around a closed network loop. Typically, a ____ topology sends data, in a single direction, to each connected device in turn, until the intended destination receives the data.

A

Ring topology

49
Q

a network has a central point (for example, a switch) from which all attached devices radiate

A

Star topology

50
Q

When interconnecting multiple sites (for example, multiple corporate locations) via WAN links, a ________ topology has a WAN link from each remote site to the main site

A

Hub-and-spoke topology

51
Q

Directly connects every site to every other site.

A

Full Mesh Topology

52
Q

A hybrid of a hub-and-spoke topology and a full-mesh topology.

A

Partial-Mesh topology

53
Q

The simplest of wireless topologies is the _______ wireless network. This means that the wireless nodes are in charge of sending and receiving traffic to each other, without the assistance of infrastructure devices, such as switches or access points.

A

ad hoc topology

54
Q

In a _________ network, a dedicated server (for example, a file server or a print server) provides shared access to a resource (for example, files or a printer). Clients (for example, PCs) on the network with appropriate privilege levels can gain access to those shared resources.

A

client/server network

55
Q

Allows interconnected devices (for example, PCs) to share their resources with one another. These resources could be, for example, files or printers.

A

peer-to-peer network
