Question
1.Refer to Figure 1-26 (page 30 of the textbook), when Host A transmits a packet to Router1 R1 using the shortest path:
a) How many physical links are there along the data link shown?
b) How many data links?
2. Refer to Figure 1-26 (page 30 of the textbook):
a) How many physical links, data links, and routes are there along the way when Host A sends a packet to Host D using the shortest path?
b) How many physical links, data links, and routes are there along the way when Host A sends a packet to Router R2 using the shortest path? (Assume that hops will be minimized across switches and routers.)
c) How many physical links, data links, and routes are there along the way when Host D sends a packet to Host B using the shortest path?
3. Refer to Figure 1-26 (page 30 of the textbook):
a) What type of single network is Network Y?
b) What type of single Network is Network X?
c) What type of protocol does Network Y follow at the data link layer?
4. In a network, there are 10 routers between Host Q and Host Y.
a) How many data links will there be along the way when Host Q transmits a packet to Host Y? (Hint: Draw a picture.)
b) How many routes?
c) How many frames?
5. How is network data delivered on the Internet versus the World Wide Web? (This question requires research beyond the text.)
