Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question:The Ricart& Argwala mutual exclusion algorithm: (a) Does not depend on time stamps in messages while Lamport's does. (b) Cannot handle the case where two or more processes request the same resource at the same time. (c) Does not require a process to send messages to the entire group while Lamport's does. (d) Requires fewer messages than Lamport's algorithm.
Think of a search engine's web host as being streamlined. This system has 100 machines that can reply to search queries. These machines can then call out to another cluster of machines using the processSearch(string query) function to actually obtain the results. You cannot ensure that the same machine will always reply to the same query because the machine that answers a given query is selected at random. ProcessSearch is a very pricy technique. Create a caching system to store the outcomes of recent searches. Don't forget to describe how you'd refresh the cache if the data changed.

Computer Science Consider a real-time stock price application (like Yahoo! finance) where the users can see the price of a stock in real-time as they change. Explain how we would implement this functionality using each of the following technologies, what would happen for a single update to take place (the steps that would take place), and what are the pros/cons of each method (which is faster? which one consumes fewer resources? which is more browser-compatible and works with older browsers?).

Native application are costly to developed since they need to written using web based application and the unfamiliarity of most programmers using this software adds to development cost b.Native application are costly because they are entirely dependent on internet connection hence developers must make sure that it can always have a good internet connection in order to function c. Native application are costly to developed since it needs to be continuously updated and maintained through the website d. Native application are costly to developed since it requires that the application must be suited only to the specific operating system in order to maximize its device…
Description:The project I am working on needs to demonstrate how two processes (parent and child) can communicatethrough a shared memory region, with the child process writing a value to the shared memoryand the parent process reading that value. This is my code and I wont run. Can you help: #include <stdio.h>#include <stdlib.h>#include <sys/types.h>#include <sys/ipc.h>#include <sys/shm.h>#include <unistd.h> #define SHM_SIZE 1024 /* shared memory size */ void error_exit(const char *msg) { perror(msg); exit(EXIT_FAILURE);} int main() { key_t key; int shmid; char *data; // Create a unique key for shared memory if ((key = ftok("shared_memory.c", 'R')) == -1) { error_exit("ftok"); } // Create the shared memory segment if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) { error_exit("shmget"); } // Attach the shared memory segment to our data space data = shmat(shmid, (void *)0, 0); if…
Which of the following statements is TRUE about CPU scheduling?Select one or more options: A scheduling algorithm for processes is preemptive if a process can be forced to give up access to the CPU. Time-sharing systems generally use a preemptive CPU scheduler. Response time is more predictable in preemptive systems than in non-interruptible systems. CPU scheduling is not required in multi-user systems. Scheduling in popular operating systems such as Linux and Windows gives the same priority to all processes. For jobs that require a lot of processing, short time periods ("time slices") are most effective. Compared to FIFO, Round-Robin is better for interactive jobs. By using a priority scheduler, all processes will always have an equal share of time on the CPU. The CPU scheduler must run / execute when a process terminates.
First class was posted in this question, third class will be posted in a different question, please refer to it, thank you: https://www.bartleby.com/questions-and-answers/computer-science-question/34b2a175-1365-4989-a811-33c7e8b66a7b Do not change the function names or given starter code in the script. Each class has different requirements, read them carefully. Do not use the exec or eval functions, nor are you allowed to use regular expressions (re module). All methods that output a string must return the string, not print it. If you are unable to complete a method, use the pass statement to avoid syntax errors. Section 2: The Calculator class Implement a class that calculates mathematic expressions. The input passed to this Calculator is in infix notation, which gets converted to postfix internally, then the postfix expression is evaluated (we evaluate in postfix instead of infix because of how much simpler it is). More details about infix to postfix conversion can be found…
