Exam 7: Local Area Networks: Part I

When two or more hubs are interconnected and a workstation transmits data,all the workstations connected to all the hubs receive the data.This is an example of a(n)____.

The hub,in most applications,has been replaced with the switch.

A ____ is a device that interconnects two or more workstations in a star-wired bus local area network and immediately retransmits the data it receives from any workstation out to all other workstations connected.

Three of the most popular local area network systems are Ethernet,IBM Token Ring,and Wireless Ethernet.

A(n)____ protocol is the software that allows a workstation to place data onto a local area network.

The ____ sublayer is primarily responsible for logical addressing and providing error control and flow control information.

____________________ (nicknamed Cheapernet)was designed to allow for a less-expensive network by using less-expensive components.

The ____ sublayer contains a header,computer (physical)addresses,error-detection codes,and control information.

IEEE created the 100-Mbps Ethernet 802.3u protocol also called ____ Ethernet.

By keeping all of the application on the server,the network can control access to the software and can reduce the amount of disk storage required on each user's workstation for this application.

Explain the cut-through architecture including its advantages and disadvantages.

Depending on user requirements,a switch can interconnect two different types of CSMA/CD network segments: ____ segments and dedicated segments.

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

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

Perhaps the strongest advantage of a local area network is its capability of allowing users to share hardware and software resources.

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

____________________ was created to support older-category wire.Thus it can operate over Category 3 or 4 twisted pair wire,as well as Category 5/5e/6 unshielded twisted pair.

One of the biggest advantages of local area networks is their ability to share resources in an economical and efficient manner.

The ____ standard was one of the first Ethernet standards approved.

The interval during which the signals propagate down the bus and back is the ____.
