- Auto-generate a private Internet Protocol address (APIPA)Popular social networking site My+Din is struggling to manage its many popular forums. Recent regulation requires the site to report users engaged in conversations about certain topics. The sheer number of users means manual monitoring is too costly and so the site has asked its many interns to come up with a solution. One intern has theorized that conversations about any given topic will see the same key words used over and over. If the most used words can be identified perhaps manual investigation can be directed towards appropriate forums. Input One line containing a single integer M (1≤M≤104), the number of messages. M more lines each beginning with a user’s name of no more than 20 characters and continuing with the content of that user’s message all in lower case. The total number of characters across all messages, including spaces, will not exceed 2×106. Output Several words, one per line, listing the words used by every single user on the forum, ordered from most to least used…research a criminal case where digital evidence obtained from a network/internet was used to help reach a verdict. Give a brief summary of the case and describe how they impact the digital evidence had. How could errors in the chain-of-custody affect the admissibility of the evidence (e.g. Hashing the files pulled from a network stream. Please cite the source!

Many systems designed in the real world need to work in synchrony with each other. This is true for web servers and IOT devices synchronizing with each other for providing online services. Consider an online food ordering system that allows the customer to create an order on a smartphone, that is received by a web server on the cloud and then transmitted to a desktop at the restaurant. When the order has been received and when the order has been completed, the desktop app sends the update to the webserver for the smartphone app to be alerted at the customer end. a. Design transition system diagrams as channel systems for smartphone app, web server and the desktop app. b. Then perform the parallel composition of the three models. Now identify, are there any unsafe possibilities. 2. Consider the following two sequential hardware circuits: (a) Give the transition systems of both hardware circuits.(b) Determine the reachable part of the transition system of the synchronous product of…
- When users post an update on social media,such as a URL, image, status update etc., other users in their network are able to view this new post on their news feed. Users can also see exactly when the post was published, i.e, how many hours, minutes or seconds ago. Since sometimes posts are published and viewed in different time zones, this can be confusing. You are given two timestamps of one such post that a user can see on his newsfeed in the following format: Day dd Mon yyyy hh:mm:ss +xxxx Here +xxxx represents the time zone. Your task is to print the absolute difference (in seconds) between them. Input Format The first line contains , the number of testcases.Each testcase contains lines, representing time and time . Constraints Input contains only valid timestamps . Output Format Print the absolute difference in seconds.

Fred would like to have one common calendar for his all 200 employees. The expected features of the new e-mail package are “background processing” that doesn't get a great deal of attention. This includes managing connections, checking for errors in commands and e-mail messages, and reacting accordingly. The e-mail software vendors offered two different e-mail system for solution. One vendor is offering an SMTP-based two-tier client server architecture. The second vendor is offering a Web-based e-mail architecture. Fred doesn't understand either one.
