Expert Solution & Answer
Chapter 5, Problem 43SG
Explanation of Solution
Techniques to collect the personal data: There are various techniques for collecting the personal data. They are,
Electronic profiles:
- Electronic profiles contain the personal data such as name address, age, mobile number, interest, and so on.
- Whenever any magazine or contest form is filled, then all the information is stored into
database . - Even any social media account can be created with help of personal data.
Cookies:
- It is a text file which is stored on a user’s computer by the web server.
- This file contains details about the user like user name, shopping cart items, viewing preferences, and so on.
- Although both spyware and cookies collects information of the user, cookies is not considered as a spyware because it cannot track everything the user does.
- Cookies may not be spyware because website programmers do not attempt to hide the cookies.
Phishing:
- Phishing scam is a false attempt to obtain confidential information like usernames, passwords, information about credit cards, bank accounts and so on.
- This is done by disguising as an honest entity via electronic communication.
- Phishing message asks the user to reply with their confidential information, or they can be in the form of pop-ups which collects user’s information...

Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2, 3.3, 4.1. Each transmission requires exactly one time unit. 1 t=0.0 2 3 45 t=1.0 t-2.0 t-3.0 6 t=4.0 t-5.0 For the CSMA protocol (without collision detection), indicate which packets are successfully transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy, then that node will not attempt a retransmission of that packet until sometime after t=5. Hint: consider propagation times carefully here.

For simplification, only consider cutting the rope at an integer position by the meter metric. Each cut has a cost associated with it, c(m), which is the cost of cutting the rope at position m. (You can call c(m) at any time to return the cost value.) The goal is to cut the rope into k smaller pieces, minimizing the total cost of cutting. B Provide the pseudo-code of your dynamic programming algorithm f(n,k) that will return the minimum cost of cutting the rope of length n into k pieces. Briefly explain your algorithm.
