Differentiate between CD-R and CD RW

After writing to a CD-R, it becomes a CD-ROM. A Compact Disc Re-Writable (CD-RW) is an erasable disc that can be reused. The data on a CD-RW disc can be erased and recorded over numerous times. NOTE: CD-RW media may not be readable outside of the drive it was created in.

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send a packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we
This project is based on SEED labs by Wenliang Du, Syracuse University.
get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure
a = IP()
a.dst '1.2.3.4
a.ttl = 3
b = ICMP()
send (a/b)
If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result
Task: Sniffing and-then Spoofing
In this task, you will combine the sniffing and spoofing techniques to implement the following sniff- and-then-spoof program. You need two VMs on the same LAN. From VM A, you ping an IP X. This will generate an ICMP echo request packet. If X is alive, the ping program will receive an echo reply, and print out the response. Your sniff-and-then-spoof program runs on VM B, which monitors the LAN through packet sniffing. Whenever it sees an ICMP echo request, regardless of what the target IP address is, your program should immediately send out an echo reply using the packet spoofing technique. Therefore, regard-less of whether machine X is alive or not, the ping program will always receive a reply, indicating that X is alive. You need to use Scapy to do this task. In your report, you need to provide evidence to demonstrate that your technique works.

Are items a through e in the following list algorithm? If not, what qualities required of algorithms do they lack?
a. Add the first row of the following matrix to another row whose first column contains a nonzero entry. (Reminder: Columns run vertically; rows run horizontally.)
[1 2 0 4 0 3 2 4 2 3 10 22 12 4 3 4]
b. In order to show that there are as many prime numbers as there are natural numbers, match each prime number with a natural number in matching the first prime number with 1 (which is the first natural number) and the second prime number with 2, the third with 3, and so forth. If, in the end, it turns out that each prime number can be paired with each natural number, then it is shown that there are as many prime numbers as natural numbers.
c. Suppose you're given two vectors each with 20 elements and asked to perform the following operation. Take the first element of the first vector and multiply it by the first clement of the second vector. Do the same to the second elements, and so forth. Add all the individual products together to derive the dot product.
d. Lynne and Calvin are trying to decided who will take the dog for a walk. Lynne suggests that they flip a coin and pulls a quarter out of her pocket. Calvin does not trust Lynne and suspects that the quarter may be weighted (meaning that it might favor a particular outcome when tossed) and suggests the following procedure to fairly determine who will walk the dog.
1. Flip the quarter twice.
2. If the outcome is heads on the first flip and tails on the second, then I will walk the dog.
3. If the outcome is tails on the first flip, and heads on the second, then you will walk the dog.

Write a function solution that, given an integer N, returns the maximum possible
value obtained by inserting one '5' digit inside the decimal representation of integer N.
Examples:
1. Given N = 268, the function should return 5268.
2. Given N = 670, the function should return 6750.
3. Given N = 0, the function should return 50.
4. Given N = -999, the function should return - 5999.
Assume that:
• N is an integer within the range (-8,000..8,000).
In your solution, focus on correctness. The performance of your solution will not be the
focus of the assessment.
