Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

Each computer interfaces with the bridge using its own segment of CAT 5 twisted-pair cable‚ which is terminated at both ends with RJ-45 connectors. What type of physical topology do you have? a. Mesh b. Bus c. Ring d. Star I believe this to be a star topology because each of the 15 work station connects to a central point

jack such as this does what two things to each wire? Secures the wire into the slot and cuts the insulation on the wire 6. What is the most critical part of the termination procedure to ensure low crosstalk on the connection? Keep the wires twisted as much as possible until reaching the termination point (RJ-45 connector): 7. How is the outer insulation covering each wire cut through during the termination procedure? When using the punch tool‚ press down halfway to secure the wire‚ then

problem with leaving abandoned cable in place in a building? Abandoned cable can really be a fire hazard 5. Why must the twisting in the individual wires be maintained in a UTP cable? When twisting cable it is very important because if it gets un twisted it can cause a lot of crosstalk and other interference. 6. How many wires does a gigabit cable use? It would be 8 wires 7. Is the labeling standard commonly used or not used? It is used about half the time 8. Grounding should be attached to what

Cat 6 cable supports up to 10 Gigabit Ethernet for up to about 37 meters or 121 feet. Cat6 cables are made up of four twisted sets of copper wire and its abilities surpass cat5 and cat5e types of data cabling because it has a structural difference in its longitudinal separator 3. Should fiber optic horizontal cabling be installed but not terminated as future proofing

Name: Eric Zells Book Title: Twisted Author: Laurie Halse Anderson Tyler is the narrator of Twisted. He considers himself an unpopular kid entering his senior year of high school who is constantly struggling with suicidal thoughts. He has always been a small guy who is teased mercilessly and hence he tries to stay under the radar. However‚ he decides to make a name for himself and uses graffiti to do so. However‚ he is caught for this behavior and put on probation. He has to do community service

entries in Table 4- 1. Use your textbook and Internet research to compose your answer. The common connector for interfacing UTP wires to a computer for networking is the Registered Jack 45 ( RJ- 45) interface. This uses eight copper wires ( four twisted pairs) to complete the connection between interfaces. The pinout for these wires defines the order in which the individual wires connect to the network interface card and how the wires transition from one end of the cable to the other. A straight
