Case Study

There is one computer in New Delhi & another in Bangalore that required to be connected with the data rate of 10 Kbps.  There are various ways to achieve inter-connectivity using any of the following options:

• Coaxial Cable

• Infrared Communication

• Micro-Wave Link

• Satellite Communications

• Optical Fiber

• GPRS

• Telephone Line Modems

• Leased Lines

• ISDN

• ATM

• Proprietary Communications Technology

Each approach has its advantages/disadvantages & cost.  Some approaches might be feasible but some might not be feasible.
Case problems :

problem5)a) describe the above-mentioned connectivity options.

b) How will you connect these computers & why?  Give justifications – if cost, performance, & feasibility are important considerations?

c) If instead of two computers, there were two LAN(s) (with data rates of 10 Gbps) which had to be interconnected, then how will you connect them?  Give justifications.

d) What is Infrared communication?  Will you use Infrared communication to achieve connectivity in either of the following scenarios:

I) Connect two computers with data rate of 10 Kbps

II) Connect two LAN(s) with data rate of 10 Gbps

Give justifications to support your answer.
