Bus Topology connects eachcomputer (nodes) to a single segmenttrunk typically coaxial cable that isreferred to as the bus.


5/43

is a network topology in which eachnode connects to exactly two othernodes, forming a single continuouspathway for signals through each node


6/43

is a type of networking wherein eachnode in the network may act as anindependent router, regardless of whether it is connected to anothernetwork or not

Is one of the most common computernetwork topology. Consist of onecentral switch/hub which acts as a

conduit to transmit messages. Easydeployment and troubleshooting

Eight-conductor data cable contains 4pairs of wires. Each pair consists of a solid(or predominantly) colored wire and a

white wire with a stripe of the same color.

Twisted pair cabling is a form of wiring in which two conductors arewound together for the purposes of canceling outelectromagnetic interference (EMI)from external sources,

electromagnetic radiation from theUTP cable, and crosstalk betweenneighboring pairs.

crimps RJ45 modular plugs. Simply place theplug with the cable in the crimp tool andsqueeze the grips together, thus causing

the plug to bite into the cable.

A router is a device that determinesthe proper path for data to travelbetween different networks, andforwards data packets to the nextdevice along this path.They connectnetworks together; a LAN to a WAN

for example, to access the Internet .
