Ch3 TXT Question 1, 3, and 6
1. How does a multipoint circuit differ from a point-to-point circuit?
Multiport circuit, in this configuration many computers are connected to the same circuit. This means that each must share the circuit with the others. The disadvantage is that only one computer can use the circuit at a time. In order words when one computer is sending or receiving data all others must wait. The advantage is in the reduction of cable needed, thus reducing cost. Point to point circuit, also called dedicated circuits, are dedicated to the use of the two computers (one on each point). This type of configuration is used when the computers generate enough data to fill the ...view middle of the document...
Fiber Optic (A geeks dream cable) Becoming widely use as the cost of the technology drops, to more acceptable prices more and more people are going to Fiber Optic Cable. This technology uses high speed streams of light pulses from the laser (LED) that carry information inside hair thin strands of glass (the fibers). One of the main advantages of Fiber Optic Cables is that it can carry huge amounts of information at extremely fast data rates. This capacity makes it ideal for data, video and audio transmissions. Fiber optic cable can also works better under harsh environmental conditions, is not heavy or bulky, and can withstand higher temperatures than copper.
6. Clearly explain the differences among analog data, analog transmission, digital data, and digital transmission.
Digital data is binary data (01010) analog data such as that which is produces by telephones, has electrical signals are shaped like the sound waves they transfer, these signals can take on many values in a wide range of possibilities not just 0 or 1. Data can be transmitted through a circuit in the same form they are produced. Computers use...
