Great set of questions but please see p.4 and 5 for the suggested answers to all questions
1. One of the commonly used physical media for Ethernet is a twisted-pair cable (see figure below; that particular cable has an “RJ45” 8P8C jack4 attached to it). Under what conditions can one such cable support two independent connections/links simultaneously (e.g., from device/port A to some other device B, and from C to D at the same time)? (4 lines MAX, references are NOT included in the line counts).

2.Explain how does using such a configuration – 2 links over 1 cable – affects the 3 key technical goals covered in class (3 lines MAX, references are NOT included in the line counts).
3. Fiber-optic cables (see figure below) are becoming increasingly popular as a medium for Ethernet. Explain how moving from copper cables (see above) to FO cables would affect the 3 key technical goals covered in class (3 lines MAX, references are
NOT included in the line counts)

1)Conditions in which Ethernet cable provides independent connection simultaneously. Full-duplex mode is an operation that allows two stations to communicate at the same time. To offer independent receiving and transmission data paths. The second condition is MAC control which controls the traffic flow and interacts in real-time.
2)This configuration ensures that the system output performance is high. It ensures that the results performance meets its specification. It must be dependable, available according to the Service Level Agreement, and scalable if necessary. Deliverable in terms of functionaliy on the intended purpose (Fitzgerald & Dennis, 1996).
3)Moving from common...
