P and Q are two processes that share a set of variables that is common. The variable includes: seq, tA and tB: Before either process starts to execute, variable seg initially has the value 10. State the possible sets of different values of seg when both processes have finished executing. Provide an order of execution of statements from processes P and Q that would produce each of the values you give. Justify your answer in detail. P ... P1: tA = seq + 1; P2: seq = tA; 10 오 Q1: tB = seq+ 2; Q2: seq = tB;

Question No: 06 This is a subjective question, hence you have to write your answer in the Text-Field given below. Consider P0,P1,P2 are three processes synchronised with semaphores S0=1,S1=0,S2=0 as shown initialised. The table below gives the code of the processes Process PO While (true) { Process PI Process P2 Wait(S2); print 1"; signal(S1), wait(S1); signal(S1); wait(so); print *0"; signal (S1); signal (S2); a If the sequence of processes schedule is P1,P2,P0,P0,P2,P0,P2,P0. What are the values printed? b. If the semaphores are initialised with S0-0,S1=1 ,S2=1. What are the values printed for the above sequence?
Consider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child…
I need to create a decision table for the following Use Case that I created for an exercise. Can anybody please help me create a decision table to the following process? Use Case: Create a new user Admin selects the “Create user” button System shows Create User screen with text: “Enter username”, “Enter password”, and “Confirm password” Admin enters username, password with the required complexity, and confirms password; Then presses, “Next” or “Enter” System checks that the username is unique/distinct System displays the User Information screen with text: “Enter recovery email address”, “Select user privileges”, and “Enter first name and last name of user” Admin enters the email address, selects one of the 3 privilege levels, and the first and last name of the user Admin presses the “Submit” button System creates the user with all specified credentials and privileges New user logs in with the given credentials System requires user to change their password by…
1. Problem Definition A critical-path analysis is a technique used to determine the schedule for a project. One method for this analysis starts by dividing a project into sequential events and then dividing each event into various tasks. Although one event must be completed before the next one is started, various tasks within an event can occur simultaneously. The time it takes to complete an event, therefore, depends on the number of days required to finish its longest task. Similarly, the total time it takes to finish a project is the sum of the time it takes to finish each event. Table 1 illustrates an example of the critical-path information for a major construction project where each row in the table contains an event number, a task number, and the number of days required to complete the task. The data are arranged so that all the tasks for event 1 are followed by all the tasks data for event 2, and so on. Event Number Task Number | Number Of Days 1 15 3 1 27 6. 1 36 4 2 15 3 18 4…
Update vaccine quantities. The system should allow the employees to select a particular vaccine and indicate either received or distributed quantity. In either case, the quantity of the selected vaccine needs to be updated accordingly in the vaccine.txtfile.E.g. Assume that the initial quantity of Pfizer vaccine in vaccine.txt file is 1 million. When the company receives a new stock, this quantity has to be added to the existing quantity of 1 million in the vaccine.txt file. In the case where the vaccines are distributed to hospitals for vaccination, the distributed quantity has to be subtracted from the quantity available in the vaccine.txt file.Note: Whenever a vaccine is distributed to hospitals, its code and the quantity distributed need to be recorded into a text file named as dist.txt. Each vaccine is expected to be distributed more than once. Hence, while testing the program, there should be at least 10 records created in the dist.txt file.3. Search vaccine and its available…

The SQLiteOpenHelper and SQLiteCursor classes are described, with a focus on how they may be used to perform create, read, update, and delete (CRUD) actions on a SQLite database.
A manager has a list of items that have been sorted according to an item ID. Some of them are duplicates. She wants to add a code to the database that assigns a 1 to the item if it is unique, and if there are duplicates, assigns the number of the duplicate. An example is shown below. The first two items are unique, so the repeat code is 1. However, Item ID 37695 is listed six times, so the codes are assigned from 1 to 6, and so on. Explain how to assign the correct code using an IF statement Item ID Repeat Code35080 135222 137695 137695 237695 337695 437695 537695 637712 137722 137757 137757 2 In cell B2 enter 1, and then type a formula into cell B3, followed by dragging the formula down column B until it aligns with the last row in the Item ID column. Which of the following is the correct formula to type into cell B3?
Your client wishes to have a program that would generate a student database in a form of Excel spreadsheet. In order to save a record to the spreadsheet, client will enter student data at the prompt, one record at a time.Every record in the database is represented by student data; record number, first name, last name, ID, GPA. Your assignment is to write the program that would get user input, one line at the time, and write them to a Comma Separated Values file. In addition, the program will need to save student record as a single string to a vector of strings, one record at a time. When user is done entering records, program should display all the lines entered by the user to the screen. Things to consider when implementing the program: 1.write_file(vector<string> &v): (1)Open file for writing (2)check if file can be open for writing (due to memory problems) (3)Prompt user to enter student records. NOTE: number of records is unknown, so program must repeatedly prompt user…
Write a Python program that connects to a sqlite database. 1- Design a program that keeps user information of a system withPython. The program you have designed must perform the operations ofviewing user information, adding new users and deleting users.User variables and actions must be defined in the classstructure.2- Keep user data in a database. Program should be able to connectto the database, and user additions and deletions should alsobe viewed on the database.
You have been asked to write a loop that outputs values in a database column ranging between 10 and 100. Any number that is not divisible by 5, and any value that is not an integer, should be ignored. When the value in the loop hits 95, break the loop prematurely. One of your team members has advised the use of break, continue, and pass statements. Define a for loop, using the range function to create the lower (10) and upper (100) limits. Define a condition that checks for zero. Define a condition that checks whether the number is divisible by 5. Define a condition that checks the data type. Define a condition that checks for 95, and breaks the loop. Define a condition that uses the pass statement if the number doesn't meet any condition. Print the number if it meets the condition. 10 15 20 25 30 35... ... 80 85 90
