Part A A client requests a webpage from a remote server on a remote island via a slow satellite link 20,000km above the earth in geostationary orbit. Calculate the time for the request to be completed. Here are some abbreviations used below: bps- bits per second, k-103, M-106 There is a Client, C, a server V, a DNS server, D. These are connected with three switches, S1, S2, S3 and 5 transmission links.
