Internet, LAN, Domains (continued) When you have completed this section of your final lab report How do we diagnose problems with internet connections? you will be able to answer at a minimum the following questions in the Observations and Conchsios What are domain names? Can they be valuable? Which is faster download or upload and why? Part D How fast can you go? We connect to the internet through an organization called an Internet Service Provider (ISP). We of course want to go as fast as possible and pay the least. Well you are at school and the question is - are you getting your money's worth? Let us check the quality of service you are provided for your student tech fee. We check the intemet access speed (bandwidth) by going to the following urt for testing the line. http://www.bandwidthplace.com/ Download Bandwidth in Megabits? Upload Bandwidth in Megabits? Following answers for download only Bandwidth in Kilobytes? How much time (give unit is required to transmit one ASCII character on this school's How many ASCII characters are transmitted in 10 seconds? In this case do you think you are getting your money's worth and why? Part E Discover what is wrong. We have learned that we use interconnecting networks to talk to other computers. They may be right nearby or clear across the planet. This of course gets me to think as to when we can expect to talk to a computer on the Moon, Mars and of course Vulcan. Well anyway back to my original train of thought. How do we get to check when our communication is not getting through There are utilities we can use. They are tracert, ping and loopback. We need to isolate the problem from our system to the extemal world. The utilities mentioned use a message called internet controlled message protocol or ICMP. They have a field called time to live or TTL for short (There we go again abbreviation after abbreviation). The property of the TTL is that when a router receives tan ICMP it decrements the TTL by 1. If the TTL becomes 0 or less it responds with an error reply. We will use this feature of the TTL in the ping and tracert utility.
