(B) Consider the requests from processes in given order 300K, 25K, 125K and 50K. Let there be two blocks of memory available of size 150K followed by a block size 350K. Which out of best fit and first fit partition  allocation schemes is most suitable for granting all the requests in this case. Show the allocations with the help  of a diagram and explain.

These operations are using C syntax and System Calls

Write a C/C++ program that accepts 2 command-line arguments: filename of a file of small instructions to interpret number of pages of space to acquire via mmap The contents of the file will consist of sets of these commands:

You are required to propose FOUR functions to develop a complete student record management system. The function are insert, delete, search, update.  In addition, you need to use sorted array to complete the system development.   Write a program by extending the code from the lab. Think and implement 4 more functions in the program (compulsory function is sorting and searching) Your must build on top of the following code.  //FileName: Student.cpp //This program illustrates attributes of class Student using simple data structure #include <iostream.h> class Student { private: struct Data { char Name[25]; char Course[30]; int Result; } stdata; public: void SetData(); void GetData(); };//class Student void Student::SetData() { cout <<”Enter student name:”; cin>> stdata.Name; cout<< “Enter student course: “; cin>> stdata.Course; cout<< “Enter student result:”; cin>> stdata.Result; };//method SetData void Student::GetData()   { cout<< “\n…

A company has a calculation strategy where the number of file systems needed indicates a disk with 1000 blocks. There are in total five files. Assume the end block, index block wherever required. Also, considering that the file control block contains the information in the order of Using contiguous, linked and indexed allocation methods compute the allocated files.

1. Write a Python script that spawns 10 processes with inputs 1,...,10 and utilises the multiprocessing method and the Pool object to compute and return the sum of integers up to and including each process's input.2. Create a Python software that uses columnwise 1D partitioning to multiply matrices to n n.
