When a child exits is returns a number in response to the parents having called wait(&status). If the number which a child returns is ex1A05, Did the child produce a core dump? Yes, it did. No, it did not. What was the exit code (as a base-ten number) of the child process? If the child exited in response to a signal, what was that signal? If it did not receive a signal enter 0, and if it did, identify the signal received as a (base-ten) number.
In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap? A. The data section B. The .text section C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory. Reset Selection
You are required to make changes in the above programs and introduce the use of compaction where required. Write code to simulate Worst-Fit Algorithm TASK2: DESCRIPTION One of the simplest methods for memory allocation is to divide memory into several fixed-sized partitions. Each partition may contain exactly one process. In this multiple-partition method, when a partition is free, a process is selected from the input queue and is loaded into the free partition. When the process terminates, the partition becomes available for another process. The operating system keeps a table indicating which parts of memory are available and which are occupied. Finally, when a process arrives and needs memory, a memory section large enough for this process is provided. When it is time to load or swap a process into main memory, and if there is more than one free block of memory of sufficient size, then the operating system must decide which free block to allocate. Best-fit strategy chooses the block…

In this project you are to design a process queue that is responsible for handling the process requests coming from different users. You have to take into consideration that users have different levels of privileges and priorities. Each user has an identification number and a password, in addition to process priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every process request received, the program should check the privileges of that request and whether it can be moved forward in the queue to be served by the operating system prior to serving the other requests. Using the programming language of your choice (preferably C+), write the process queue that would handle the user request. The program must allow for requests coming from different users or from one user.

In C programming, write a method int ksyscall_proc_get_name(char *name). *Copies the current process name to the buffer provided * char *name - pointer to the buffer to copy the name. If there is an error return -1, if success return 0.
Please write in C/C++Write a program that spawn 2 thread: a producer and a consumer The producer thread MUST open an input file and repeatedly copy values to a CIRCULAR BUFFER The consumer should open an output file and repeatedly copy values from the same circular buffer to the file. If the producer is unable to write to the buffer (because it does not contain enough empty elements), or if the consumer is unable to read from the buffer (because it does not contain enough unread items), then it should proceed to the next iteration, choosing a new random number of bytes to copy.
Which example uses the SOLID SRP principle correctly and does not violate it?

Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifierThere are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the records.Write an assembler subroutine GetMax that will scan the entire list and find the highest mark. If there is a tie, the first student in the list with the highest mark should be found. The subroutine should return the starting address of this record in address register a3.
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.
PYTHON CODE (DATABASE) #flask_SQLAchemy using: db.session.add() and db.session.delete (add): Implement a database code that allows the user to enter the name of a fruit. This fruit should be saved in a list of favorites. If it’s already on the list, nothing should happen. (delete):Now the user will be allowed to enter a name of a fruit. This fruit should be deleted from the list of favorites. If it’s not on the list, nothing should happen. (output): The ouput page should return the statement “You have X saved fruits”, where X is the number of fruit the user has saved, as well as a list of the saved fruits. The number should increment when a new fruit is entered, and decrement when a fruit is deleted.
