Exam 7: Local Area Networks: Part I

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

Most switches are transparent, which means they learn by themselves.

The IEEE 802.3z standards are also known as ____ Ethernet.

____________________ 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.

The ____________________ design refers to the pattern formed by the locations of the elements of the network, as it would appear if drawn on a sheet of paper.

All bus networks share a major disadvantage: In general, it is difficult to add a new workstation if no tap currently exists.

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

One of the most common standards for broadband (analog) Ethernet was the ____________________ specification.

Switches can be used in combination with routers to further isolate traffic segments in a local area network.

Switches can significantly decrease interconnection traffic and increase the throughput of the interconnected networks or segments.

What are some of the application areas where a LAN can be an effective tool?

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

Early local area networks transmitted data at only ____ million bits per second.

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

____________________ means that when the signal is transmitted from a given workstation, the signal propagates away from the source in both directions on the cable.

A local area network cannot interface with other local area networks.

The local area network first appeared in the 1950s.

In IEEE 802.3 standard for CSMA/CD, frames shorter than 64 bytes are considered ____________________, or frame fragments.

________________ allows you to combine two ore more data paths, or links, into one higher-speed link.

The ____________________ makes it possible to logically remove cyclic paths within a collection of multiple LANs.
