It is a network of users that share computer resources in a limited area. - CORRECT ANSWER LAN Local Area Network - CORRECT ANSWER LAN How are Local Area Networks defined? - CORRECT ANSWER In terms of protocol and the topology used for accessing the network. A set of rules established for users to exchange information - CORRECT ANSWER Protocol The network architecture used to interconnect the networking equipment. - CORRECT ANSWER Topology What are the most common topologies for LANs? - CORRECT ANSWER Ring, Bus, and Star Uses a token that is placed in the data channel and circulates around the ring. - CORRECT ANSWER Token Ring topology A deterministic network - CORRECT ANSWER Token Ring Topology Each station connected to the network ensures access for transmission of its messages at regular or fixed time intervals - CORRECT ANSWER Deterministic What are the disadvantages of the Token Ring system? - CORRECT ANSWER 1. If an error changes the token pattern, it can cause the token to stop circulating. What is a disadvantage of the Token Ring system from the troubleshooting and maintenance? - CORRECT ANSWER The token ring path must be temporarily broken or interrupted if a computer or any device on the network is to be removed or added to the network. What is a solution to the troubleshooting and maintenance disadvantages of the Token Ring system? - CORRECT ANSWER Connect each computer or device on the network to a central token ring hub. A device that manages the passing of the token instead of relying on individual computers to pass it. - CORRECT ANSWER Token ring hub How does the token ring hub improve the network? - CORRECT ANSWER It improves the reliability of the network. Topology whereas the computers share the media or coaxial cable for data transmission. - CORRECT ANSWER Bus topology The coaxial cable that is looped through each networking device to transmit data in a bus topology - CORRECT ANSWER ThinNet In this topology, all devices on the network can see each other's data traffic. - CORRECT ANSWER Bus topology Topology whereas each computer must wait for pauses in transmission or until the transmission from one device is complete before initiating a new transmission onto the network. - CORRECT ANSWER Bus topology What are the disadvantages of a bus topology? - CORRECT ANSWER "1. Data can be corrupted if ore than one device on the network transmits at the same time and will have to be resubmitted. 2. The use of the shared coaxial cable prevents data transmission from being very bandwidth-efficient." Which topology is seldomly used in modern networks? - CORRECT ANSWER Bus topology What is the most common topology used in today's LANs? - CORRECT ANSWER Star topology Topology that uses twisted-pair cables with modular plugs to connect computers and other networking devices. - CORRECT ANSWER Star topology Topology whereas each device is connected to a switch or hub - CORRECT ANSWER Star A switch or hub facilitates the transfer of data between networking devices in this topology - CORRECT ANSWER star
