Please help in answering the 2 questions below. Thank you.

1. Network Media
XYZ Corp. is planning a new network. Engineers in the design shop must be connected to the accountants and salespeople in the front office, but all routes between the two areas must traverse the shop floor, where arc welders and metal-stamping equipment create potent amounts of EMI and RFI. Both the engineering and the front office areas will use 100BaseT (twisted-pair Ethernet), how might you interconnect those two areas? Justify your answers

2. Standards
Some say that one of the great problems in networking is the lack of enforceable standards, so that the equipment of any manufacturer can work with any other manufacturer "off the shelf". Do you agree? Justify your answers

1. Most Ethernet clusters do not have a problem with EMI (Electro-Magnetic Interference), but it is something to keep in mind when designing a large system. .

In general Ethernet is relatively immune to EMI with short runs. However within a cluster the situation is worse than you might guess from non-cluster experience.

There are three principal connection schemes: twisted pair, coaxial, and fiber optic cable. Twisted pair (TP) is the most common form of transmission medium in use today. TP is a pair of wires twisted together and combined to form a cable. The entire cable is usually surrounded with a tough PVC (Poly(vinyl chloride)) sheath to protect it from ...
