- I'm bit confused on how paging allocation in this case. How would we know what the Best, worst, first, next page allocation would be for each of the requests? Assume the bolded USED* is the start for worst, first and next.Write a program that implements the FIFO and LRU page-replacement algorithms presented in this chapter. First, generate a random page reference string to each algorithm, and record the number of page faults incurred by each algorithm. Implement the replacement algorithms so that the number of page frames can vary from 1 to 7. Assume that demand paging is used.6. In an e-commerce site, a seller decides to provide an M% discount on his XYZ company's those products where the product quantity is greater than 65 in the database. Implement the server-side of the web page in PHP and MySQL. The database tables must be illustrated with the code. [Here, M is the last digit of your ID] InformationId:0And Please proivide Right ans in short.
- Computer Science Write a simple Bean to display the current Date and invoke it from the Java Server Page. Specify the Path which has to be set for the JSP page to invoke the bean. I need to figure out how to create a JavaBean file (.java) and connect it with a JSP file. It needs a getter and setter for the current date. The existing answers on Chegg only link to the existing built-in module and don't address the assignment questions. Please provide some feedback on how to do this or something similar. Thank you!You can use URLs to access information on the Web from within Java programmes. (uniform resource locators). MindSlave software programmers (working on their new NetPotato browser) want to maintain track of a potentially enormous bookmark list of frequently visited URLs. It would be ideal if they could have arbitrary access to the values saved in the list. Is a List a suitable data structure? (Tip: If not, why not?)You can use URLs to access information on the Web from Java programmes. (uniform resource locators). Programmers at MindSlave Software would like to manage a potentially sizable bookmark list of frequently visited URLs for their new NetPotato browser. They would find it most helpful if they had unrestricted access to the list's preserved values. Is a List the right kind of data structure? If not, why not? (Hint:
- Implement a dynamically resizable hash table to store people’s names and Social Security numbers. Use the extraction method with division using the last four digits of the Social Security number. Use an initial table size of 31 and a load factor of 0.80. Use open addressing with double hashing using an extraction method on the first three digits of the Social Security number.Write a script using PHP that takes a link from the user and parses through its associated web page to print a list of every link embedded on that site. This program must work recursively, so for each link that gets printed, the program should automatically take each of those links as a new input and do the same for them until there are no more links left. If the same link exists twice on the same page, or if it exists on more than one page, the program should ignore all duplicate instances of the link.Assume we wish to resize an existing hash table because the current hash table is becoming too small for the application. Without writing code briefly describe the process of resizing a hash table by "copying" the old data to the new hash table. What is the expected complexity of your process using Big-O notation. Justify your complexity measure. An example of a hash table before resizing is given.
- In the variable-length record representation, a null bitmap is used to indicate if an attribute has the null value. a. For variable length fields, if the value is null, what would be stored in the offset and length fields? b. In some applications, tuples have a very large number of attributes, most of which are null. Can you modify the record representation such that the only overhead for a null attribute is the single bit in the null bitmap.The following are the operations that you can do using a single linked list. Choose only one operation then create the algorithm and simulate. The attached Rubric will be used in evaluating the activity. 1. Delete a particular node in a single linked list 2.

For each problem, also implement client actors for sending the messages required for beginning the required computation. Use these client actors for testing your application actors. Recall the card shuffling problem. In a Faro shuffle, a stack of cards is broken up into two, and then combined so that a card from one sub-stack is followed by one from the other, and so on. A perfect Faro shuffle breaks up the stack into two sub-stacks of exactly the same size, and then combines them in the manner described above. An out-shuffle results in the top and the bottom cards of the stack remaining the same after the shuffle; an in-shuffle results in these cards becoming the second and the second last cards of the shuffled stack. Implement a shuffler actor which accepts a message containing a deck of cards as a list of even length, an integer indicating the number of times that the deck is to be shuffled, and a boolean…
