There are two basic approaches to the design of OS kernel. One is called microkernel approach, and the other is called ___ approach.

(a) FCFS with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1. (b) FCFS with a Ready Queue per CPU. Processes A, B, and C go to CPU1 and processesD, E, and F go to CPU2. (c) HRRN with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1.
Facts: Facts about Deadlock Deadlock is a situation that occurs in OS when any process enters a waiting state because another waiting process is holding the demanded resource. Deadlock is a common problem in multi-processing where several processes share a specific type of mutually exclusive resource known as a soft lock or software. Deadlock is a situation where a process or a set of processes is blocked, waiting for some other resource that is held by some other waiting process. It is an undesirable state of the system. The following are the four conditions that must hold simultaneously (Links to an external site.) for a deadlock to occur. Mutual Exclusion –A resource can be used by only one process at a time. If another process requests for that resource then the requesting process must be delayed until the resource has been released. Hold and wait –Some processes must be holding some resources in nonshareable mode and at the same time must be waiting to acquire some more…
Modern Operating Systems must tackle the challenges of Synchronization and Deadlock. 'Process Synchronization' is the task of coordinating the execution of processes in a way that no two processes can have access to the same shared data or resource. A process requesting a resource may have to wait, if the resource is not available at that time. Sometimes, a waiting process is never able to change state, because the resources it has requested are held by other waiting processes; this situation is called 'Deadlock'. In concurrent programming, a "critical section" is a part of a multi-process program thatmay not be concurrently executed by more than one of the program's thread. Let us consider a 2 processes solution: do {flag[i] = TRUE;while(flag[j]); %waitCRITICAL SECTIONflag[i] = FALSE;REMAINDER SECTION} while (TRUE);Pseudo-code of $P_i$ (the one of $P_j$ is symmetric) a) Does the given solution satisfy the mutual exclusion requirement?

true or false a. All of the instructions in a System function call in a user-program are executed in kernel-mode. b. A process immediately upon creation at t=0 creates 10 threads; each of the threads intends to sleep for 2sec and then execute code for 4sec. In the mean-time the process terminates after the thread creation task that lasts 1sec. It is possible that the wall-clock (outside clock) time of the execution of a thread will be more than 40sec. c. The PCB of a process is stored in an individual process's memory in user-space.
When a process p requests a resource using the request resource function, its state is set to ______________ if the requested resource is unavailable. Ready Blocked Ready Suspended The PCB contains an out-of-date copy of the CPU state of process Q when Q is running. True False The main benefit of using virtual CPUs is that they increase processing speed. True False
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.

When a process is in the "Blocked" state, awaiting the completion of an I/O operation. When a service is terminated, it transitions to one of the following states: a) Terminated state, b) Suspended state, c) Running state, or d) Ready state.
When using a multithreaded operating system, a programme (like Google Chrome) is managed by a single process, which is responsible for spawning all of the threads. Explain both the positive and negative effects that adopting this multithreading strategy may have on the programme if you choose to do so.
