Exam 7: Local Area Networks: Part I

Explain the switch filtering function.

A(n) ____________________ is a logical subgroup within a local area network that is created via switches and software rather than by manually moving wiring from one network device to another.

In ____________________ segment networks, a switch may be connected to a hub (or several hubs), which then connects multiple workstations.

A hub is a simple device that requires virtually no overhead to operate.

A ____ system transmits 10-Mbps baseband (digital) signals over twisted pair for a maximum of 100 meters per segment length.

In a ____ architecture, the data frame begins to exit the switch almost as soon as it begins to enter the switch.

A hub is designed to perform much faster than a switch.

Two different signaling technologies can be used with a bus network: baseband signaling and ____ signaling.

The ____________________ allows for a CSMA/CD network to simultaneously transmit and receive data to and from a workstation.

The 802.11 specification defined six different types of physical layer connections.

If a switch has eight 100-Mbps ports, the backplane has to support a total of ____ Mbps.

The most popular example of a contention-based protocol is the token-passing protocol.

The ____________________ Ethernet standard is also known as IEEE 802.3ae.

The ____________________ is a device that connects workstations to local area networks and retransmits the incoming frame.

A cut-through switch does not store a data frame and then forward it.

A(n) ____________________ is a device that interconnects two local area networks and can use processing power to direct a frame out a particular port, thus reducing the amount of traffic on the network.

A ____ is a device that interconnects two segments of local area networks and acts as a filter.

The logical link control sublayer defines the layout or format of the data frame, simply called the frame.

The tap is a(n) ____________________, as it does not alter the signal and does not require electricity to operate.

The local area network software called a ____ server provides workstations with the authorization to access a particular printer, accepts and queues prints jobs, prints cover sheets, and allows users access to the job queue for routine administrative functions.
