ii)Detail the four abstraction layers that make up TCP/IP. ii) Provide a scenario in which two computers share a video file via an unencrypted ftp connection using a weak TCP three-way handshake.
What is an IP address, exactly? The term "mnemonic address" stands for "address you can easily recall." How many distinct spaces are supported by a 32-bit representation? Can you tell me how many computers may be part of a single domain?
1. What is the difference between packet fragmentation (i.e., at network layer) and frame frag- mentation (i.e., at link layer) in terms of purpose? 2. Suppose that host A is connected to a router R1, R1 is connected to another router, R2, and R2 is connected to host B. Suppose that a TCP message that contains 800 bytes of data and 20 bytes of TCP header is passed to the IP function at host A for delivery to B. Show the Total length, DF, MF, and Fragment offset fields of the IP header in each packet transmitted over the three links. (Assume that link A-R1 can support a maximum frame size of 1024 bytes including a 14-byte frame header, link R1-R2 can support a maximum frame size of 512 bytes, including an 8-byte frame header, and link R2-B can support a maximum frame size of 432 bytes including a 12-byte frame header.) (*hint: the Fragment offset field is denominated by 8-bytes, not bytes) 3. What is the purpose of the path MTU discovery process (see textbook Figure 5-42) and why does…

What is a private network address and how does it work? Do you think it's possible for a datagram with a private network address to ever appear on the broader public Internet? Explain.
Where can we even begin to define what an IP address is? What do mnemonic addresses provide for? How many domains can a 32-bit representation hold? Is there a hard limit to how many machines may be part of a domain?
Can you describe the format of a private network's address in the virtual world? Can a datagram destined for a local area network (LAN) accidentally be routed to the Internet? Explanation.
Why do you need a private network address? Is it feasible that a datagram with a private network address will ever surface on the public Internet as a whole? Explain.
