Let's implement the FIRST FIT contiguous memory allocation technique. Ask the user toenter number of free memory partitions along with size of each (fixed partitions). Thenaccept the number of processes. The user also enters the memory requirement for eachprocess. Your program then allocates the free memory partitions to the arriving processes.You need to keep track of the internal fragmentation and display the output as follows:INPUTEnter number of free partitions/Memory holes: 4Enter the size of each free partition/Mem Hole in KBsMemory Hole 0:220Memory Hole 1:340Memory Hole 2:115Memory Hole 3:720Enter the number of processes in ready queue: 3Enter the memory requirements of each process in KBSProcess 0: 240Process 1:512Process 2:310OUTPUTProcess No.012Partition Allocated13No allocationInternal Fragmentation100208

Write and test a MIPS assembly language program that does the following:a) Open a text file "input.txt" and read all characters into an array in memory. Limit the length ofthe array to 1000 bytes. The maximum number of characters to be read should be 1000 characters.The actual number of characters depends on the file length. MARS provides the system calls foropening and reading a text file. If the "input.txt" file does not exist in the same folder then theprogram should display an error message and terminates.Error: input.txt does NOT exist.b) If the "input.txt" file exists, then print the content of the array as one long string. For example,This is a test file for testing MIPS assignment 2.It contains letters and digits, such as 12345.c) Traverse the array character by character. Count all letters, digits, and words. A word begins witha letter and ends with a letter A-Z or a-z. You can detect the end of a word by checking that thenext character is not a letter. A single letter is…
Write a C++ program that requests any number of input integers from user, sorts and displays the input integers in ascending order using bubble sort algorithm. Provide a written explanation and output screenshots of your code. REMINDER: Use dynamic memory allocation in C++. Do not put all your codes inside main() function. Your sorting algorithm codes must be placed inside a user-defined function.
Problem 3. This problem is about the same file foo as in the previous problem, but before it is modified. A program opens it for reading and gets back the file descriptor number fd. The program has a character array char buf [30]. The program now does the following: if ((rv = read (fd, buf,20)) < 0) { ...handle error... } if ((rv = read(fd,buf,20)) < 0) { ...handle error...} a. What does each call return (assuming no errors)? b. What do the first 20 bytes of the character array buf contain after the second read call? c. What do the last 10 bytes of buf contain?
Write a function “SortDescending” that will take two values in R4 and R5 asinputs, and store the larger value in R4 and the smaller one in R5 when called. Ifyou need to use other CPU registers, restore their content such that the callingfunction does not notice any changes.
I have seen some programs for these has been assignment but can this Assignment be programmed any other way? Thank you Memory Management Programming Assignment implement and test the GET-MEMORY algorithm This algorithm uses the Next-Fit(First-Fit-With-A-Roving-Pointer) technique. implement and test the FREE-MOMORY algorithm Implement the “GET_MEMORY” and “FREE_MEMORY” algorithms. Comprehensive testing must be done for each algorithm. Following are sample run results for each: GET_MEMORY IS RUNNING……… Initial FSB list FSB# Location Size 1 7 4 2 14 10 3 30 20 . . . . . .

2. a) Your colleague has invented a new scheduling algorithm using the multilevel queue approach. This list of processes showing CPU burst times is below. There are three queues used in the application. The processes all start on the first queue and receive upto 10ms of burst time. Once the process has received the 10ms on the first queue, if the process still requires burst time it is passed to the second queue where it receives upto 20ms. Once the process has received the 20ms on the second queue, if the process still requires burst time it is passed to the third queue where it receives CPU time until it is completed. The operating system will only start allocating CPU time to processes on the second queue when queue 1 is empty. The operating system will only start allocating CPU time to processes on the third queue when queue 2 is empty. Process Number P1 P2 P3 P4 Burst time (ms) 21 8 35 50 i) Does this algorithm give higher priority to any queue over the others and any processes…
