You've been asked to pick a new network server for your company and have decided to focus on three measures - BER (bit error rate), data rate, and weight.

 BER is the number of bits that arrive incorrectly divided by the total number of bits transmitted. Data rate is the number of bits transmitted per second.

Weight is in pounds.

 A. Which device should be chosen based on the requirements and analysis of the data shown? Why?

B. Briefly explain two of the three errors present in this study?

		JNK		PBL		ZAC
Requirement	Weight	Score	Wt Score	Score	Wt Score	Score	Wt Score
BER	50%	0.002	.001	.003	.0015	.0004	.0002
Data Rate	50%	2 Gb/s	1 x 109	1 Gb/s	0.5 x 109	1.5 Gb/s	0.75 x 109
Weight	10%	3 lb	.3	4 lb	.4	5 lb	.5
Total	110%		1 x 109		0.5 x 109		0.75 x 109
