- Write a C program which takes four command line arguments: two file names and twonumber of elements. Your program must check if correct number of arguments aresupplied and terminate if not. Your main process must create three processes: The firstand second processes must open / create files by the given names and fill them with thegiven number of random integers (one integer per line) and terminate. The thirdprocess must execute “sort” command with necessary arguments so that it numericallysorts both files and display the combined result on screen.Before creating the third child process, main process must wait for the other two child processes to end.Computer Science I get an error in my code: Exception thrown at 0x00000001 in Project4.exe: 0xC0000005: Access violation executing location 0x00000001.

If you follow the translation steps in the multi-level paging, the first Page FrameNumber (PFN) gives the address of: a. virtual address space b. page table c. page directoryCreate a program in C++ which simulates a direct cache. The memory array that contains the data to becached is byte addressable and can contain 256 single byte entries or lines. The cache has only 8 entriesor lines. The Data field in each line of the cache is 8 bits. Since the data stored in each line of the cache isonly 8 bits, there is no need for a line field. Only a tag field is needed which is log2(256) = 8 bits.The memory array can be filled with any values of your choice. The program should work by taking userinput of a memory address (index). This input represents the memory data that should be cached.Check the cache to see if the item is already cached. If it is not, your program should counta cache miss, and then replace the item currently in the cache with the data from the inputted address.Allow the user to input addresses (in a loop), until they so choose to end the program. The program should output the number of cache misses upon ending.
- Turn on the Non-executable Stack Protection Operating systems used to allow executable stacks, but this has now changed: In Ubuntu OS, the binary images of programs (and shared libraries) must declare whether they require executable stacks or not, i.e., they need to mark a field in the program header. Kernel or dynamic linker uses this marking to decide whether to make the stack of this running program executable or non-executable. This marking is done automatically by the gcc, which by default makes stack non-executable. We can specifically make it nonexecutable using the "-z noexecstack" flag in the compilation. In our previous tasks, we used "-z execstack" to make stacks executable. In this task, we will make the stack non-executable. We will do this experiment in the shellcode folder. The callshellcode program puts a copy of shellcode on the stack, and then executes the code from the stack. Please recompile call shellcode.c into a32.out and a64.out, without the "-z execstack"…Write a C program that implements the parent producer and child consumer algorithms. The parent process must copy an entire source file ("input.txt") to a destination file. In addition, the parent process must produce the file contents into shared memory as read from a source file (SRC_FILE) in chunks using the read() system call. The chunk size (CHUNK_SIZE) is the same for both read() and write(). It will be accepted as input by your program as a command-line argument.PLEASE ONLY USE 8051 MICROCONTROLLER (AT89C51 FOR EXAMPLE) AND ASSEMBLY LANGUAGE, NOT ANY OTHER MICROCONTROLLER OR LANGUAGE, THANKS.
