CBR response time hikes initially but come down gradually compared with UBR which has faster response time at initial but hiked gradually towards the end of transmission. * Anomalies: In real life application‚ UBR better fits FTP application as the delay is at acceptable rate and does not even require to be in constant rate of transmission. Question 2 Email Download Response Time & FTP Download Response Time * Graph above shows both applications are well suited in ABR (green line)

aspect of this idea is the presence of infrastructure that is in place for power distribution‚ and the rise of multimedia services over it could be much more valued than any existing wired alternative. For example‚ if we try to rebuild the whole transmission system using optical fiber instead of cabling it would cost a great deal and would be irrelevant‚ whereas providing access to the Internet by using the existing cable lines is more beneficial. As electrical power is indispensible so is the

generally located far away from the load centers. High voltage transmission lines are used to transmit the electric power from the generating stations to the load centers. Between the power generating station and consumers a number of transformations and switching stations are required. These are generally known as substations. Substations are important part of power system and form a link between generating stations‚ transmission systems and distribution systems. It is an assembly of electrical
