The wrong type of connector is being used.

The untwisted length of each wire is too long.

The woven copper braid should not have been removed.

The wires are too thick for the connector that is used.

RJ-11

DIN

PS-2

It is usually cheaper than copper cabling.

It is able to be installed around sharp bends.

It is easier to terminate and install than copper cabling.

It is able to carry signals much farther than copper cabling.

The two strands allow the data to travel for longer distances without degrading.

They prevent crosstalk from causing interference on the connection.

They increase the speed at which the data can travel.

They allow for full-duplex connectivity.

It determines the path to forward packets.

It monitors the Layer 2 communication by building a MAC address table.

It accepts Layer 3 packets and encapsulates them into frames.

It encrypts data packets.

It provides media access control and performs error detection.

Logical topologies refer to how a network transfers data between devices.

Physical topologies are concerned with how a network transfers frames.

The logical topology is always the same as the physical topology.

Physical topologies display the IP addressing scheme of each network.

half duplex

multiplex

full duplex

simplex

Each end system is connected to its respective neighbor via an intermediate device.

End devices connect to a central intermediate device, which in turn connects to other central intermediate devices.

All end and intermediate devices are connected in a chain to each other.

End devices are connected together by a bus and each bus connects to a central intermediate device.

Network 1 uses CSMA/CA and Network 2 uses CSMA/CD.

Network 2 uses CSMA/CA and Network 3 uses CSMA/CD.

None of the networks require media access control.

All three networks use CSMA/CA

Network 1 uses CSMA/CD and Network 3 uses CSMA/CA.

error detection

The transmitting node sends a beacon to notify that a data frame is attached.

The receiving node identifies the beginning of a frame by seeing a physical address.

The transmitting node sends an out-of-band signal to the receiver about the beginning of the frame.

The transmitting node inserts start and stop bits into the frame.

to define the media access processes performed by network hardware

to provide data link layer addressing

to provide access to various Layer 1 network technologies

to mark frames to identify the network layer protocol being carried

the measure of the transfer of bits across the media over a given period of time

the amount of data that can flow from one place to another in a given amount of time

the speed at which bits travel on the network

the measure of usable data transferred over a given period of time
