What is the difference between standard and dynamic routing? When do you think you'd use passive routing? When do you think you'd use changeable routing? What is the purpose of the data connection layer? What are the distinctions between connectionless messaging and connection-oriented messaging? When do you prefer one over the other? Describe four different kinds of sounds. Which is most likely to cause network administrators the most trouble? What are the three methods for decreasing errors, as well as the kinds of noise they affect? What distinguishes autonomous routing from controlled routing? When do you prefer one over the other?

Ethernet was pushed by a vendor consortium, whereas token ring was mainly an IBM offering, despite being standardized. Ethernet triumphed, and no one mentions token ring anymore. Token ring employed a hub-polling method. Describe several possible outcomes for Ethernet. The causes were both technological and business-related. What is TCP/IP's components and what do they do? Who is the main TCP/IP user? explain in detail.
