In order for network devices to communicate with other devices, they must be connected with different types of network media. The way that these devices are connected is known as a ___.

A

topology

A ___ ___ provides a general description of how the devices on the network link to each other physically and logically.

A

network topology

A ___ ___ describes precisely how devices connect, such as how the wires run from machine to machine.

A

physical topology

86
Q

A ___ ___ describes how the signals used on the network travel from one computer to another.

A

logical topology

87
Q

There are five principal topologies used in LANs:

A

bus, ring, star, mesh, and hybrid

88
Q

Both ends of the ___ topology must have terminating resistors to prevent signals transmitted on the wire from echoing back and causing interference.

A

bus

89
Q

All devices are connected by one cable. Bus topologies were used in early networks and used ___ ___ for the media.

A

coax cable

90
Q

The ___ topology has multiple single points of failure. If any individual device fails, devices on either side of the failed device lose connectivity to each other. Also, if the cable itself fails, all devices lose connectivity.

A

bus

91
Q

The following is a picture of what topology?

A

Bus

92
Q

All end devices are connected to a single infrastructure device, such as a hub or a switch. However, all end devices have their own individual cables rather than all devices sharing a single cable. A cable break affects only one end device instead of all devices. ___ topologies still have a single point of failure. If the central device fails, all other devices lose connectivity.

A

Star topology

93
Q

The following is a picture of what topology?

A

Star

94
Q

Every computer system is connected in a complete loop. So, ___ topologies are built with two, counter-rotating rings. Note the
dotted lines in the figure. Their arrows point the opposite direction of the arrows on the solid lines. If a device fails, the devices on both sides of the failed device automatically loop the counter-rotating rings together to maintain connectivity for all other devices on the ring.

A

Ring Topology

95
Q

The following is a picture of what topology?

A

Ring

96
Q

Connects each node or device is connected with with multiple links to other devices. This provides multiple paths between any two nodes. Failure to a single device will not cause the entire network
to break. While ___ networks provide the redundancy, they are more costly to implement due to the extra cost of more cabling.

A

Mesh Topology

97
Q

A ___ Topology is the combination of the topologies above.Most of the today’s networks are a ___ topology. They are usually a
combination of a mesh topology and a star topology.
