This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The Long-Term Scheduler, which is also known as the Job Scheduler, is the component that is in charge of controlling the Degree of Multiprogramming, or the total number of processes that are now in the ready state. This component is also known as the Job Scheduler. So, the long-term scheduler is in charge of choosing which processes are going to be initiated so that they can enter the ready state.
Which scheduler makes it possible to do more than one thing at once?
Mid Term Scheduler
The swapping process also includes medium-term scheduling. The processes are deleted from memory as a result. It decreases the amount of multiprogramming that is required. The medium-term scheduler is in charge of taking care of the processes that have been swapped out.
Which scheduler has the potential to restrict the amount of multitasking?
Since it is involved in swapping, the medium-term scheduler is often referred to as the process switching scheduler. The memory occupied by processes can be freed up by using this scheduler. The medium-term scheduler reduced the amount of multi-programming that could be done at once.
What steps can be taken by a scheduler to increase the amount of multiprogramming?
Medium-term Scheduler: As a result, using a medium-term scheduler brings the level of multiprogramming down. After a period of time, when the main memory becomes available, the medium-term scheduler swaps-in the swapped-out process to the main memory, and the execution of the swapped-out process is restarted from where it left off.
Which scheduler is responsible for controlling the amount of multiprogramming that is the number of processes that are running in memory?
The short-term scheduler, also known as the CPU scheduler, is responsible for allocating the computer’s central processing unit (CPU) to one of the processes that are ready to be executed. The amount of simultaneous programming is determined by the long-term scheduler.

How many different kinds of programming are there?
The term “degree of multiprogramming” refers to the greatest number of processes that can be accommodated by a system with a single processor in an effective manner. The following is a list of some of the elements that can affect the degree of multitasking: The quantity of memory that is free and can be distributed to processes that are running is the most important consideration.
Who should be held accountable for the degree of multiprogramming?
The Long-Term Scheduler, which is also known as the Job Scheduler, is the component that is in charge of controlling the Degree of Multiprogramming, or the total number of processes that are now in the ready state. This component is also known as the Job Scheduler. So, the long-term scheduler is in charge of choosing which processes are going to be initiated so that they can enter the ready state.
What exactly does it mean to be a scheduler?
The coordination of appointments for employees, customers, or patients is the responsibility of a Scheduler, often known as an Appointment Scheduler. Their primary responsibilities consist of creating weekly employee schedules, deciding the lengths of appointments, and calling patients or customers to inform them of the appointment or meeting times that have been scheduled for them.
What exactly is a long term scheduler supposed to do?
When an attempt is made to run a program, the long-term scheduler decides whether or not to admit it to the set of processes that are currently being executed. This means that the admission of the program into the set of processes that are currently running can be delayed or authorized by the long-term scheduler.
What exactly is a scheduler, and what kinds are there?
A piece of system software known as a scheduler gives users the ability to manage the scheduling of various processes. There are three different kinds of timetables: 1) Long term, 2) 2) In the near term 3) Medium-term. The long term scheduler is responsible for regulating the program, selecting processes from the queue, and loading those processes into memory so that they can be executed.
Which scheduler is only used extremely infrequently yet regulates the amount of multiprogramming that can be done?
The short-term scheduler is called into action an extremely high number of times (in milliseconds). The long-term scheduler is only activated for very brief periods of time (seconds or minutes). The amount of simultaneous programming is determined by the long-term scheduler.
Who is in charge of determining the level of multitasking allowed while scheduling processes?
The level of multiprogramming is mostly within the control of the Long Term scheduler. The jobs that are currently in the pool are combed through by the long term scheduler in an effort to select the optimal proportion of IO-bound and CPU-bound activities.
What is the scheduler speed that is the Mcq fastest?
7. Which speed of the schedulers is the fastest? The explanation behind the short-term schedule is as follows: When compared to the other two, speed is the most rapid.
What are the goals of using many programs at once?
Explanation: The use of the central processing unit (CPU) should be increased as a result of multitasking. In most cases, a single process will not be able to consume all of the CPU or I/O that is available; instead, another process will be able to use it whenever the CPU or I/O is free. This capability is made available to the operating system via multiprogramming, which maintains numerous programs in a ready queue.
What exactly is this “starvation OS”?
The issue known as starvation arises when high priority processes continue to run while low priority processes become stalled for an extended amount of time. A continual stream of higher-priority processes can prevent a low-priority activity from ever obtaining the CPU in a densely loaded computer system. This is because higher-priority processes are given priority over lower-priority ones.
What does “dispatcher OS” stand for?
The module known as the dispatcher is what hands over control of the central processing unit (CPU) to the program that has been chosen by the short-time scheduler. This part of the function includes: Shifting focus to the context. Making the switch to user mode. navigating to the correct position within the user program so that the program can be restarted.
What consequences will follow the conclusion of the process?
When a process comes to an end, what will the next step be? Explanation: When a process finishes, it is removed from any and all queues that it was in. All of the resources that had been allocated to that specific process are freed up, and then all of those resources are given back to the operating system…. The long-term scheduler will choose processes from the job queue and move them to the ready queue when it is appropriate.
What are some of the other names for a command interpreter?
An essential component of any computer operating system is the command interpreter. It acts as a gateway between the user and the computer provided by the system. In common parlance, a command interpreter may also be referred to as a command shell or just a shell.
What are the three distinct categories of schedulers available?
Operating systems may include as many as three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler. The long-term scheduler is used to plan events that are more than one hour in the future.
What are the characteristics of a good scheduler?
They should be resourceful and imaginative in their approach to challenges, and they should be able to identify, in the majority of cases, the appropriate person(s) within the team to assist them in swiftly and effectively resolving the issue. When faced with any issues that may arise in the course of scheduling projects, schedulers should employ a methodical strategy for finding solutions.
What exactly are talents in scheduling?
The ability to plan your activities in such a way that you are able to complete all of your projects and goals according to your priorities as well as within the available time limit is referred to as the scheduling skills. This ability allows you to overcome situations that are difficult and frustrating for you by planning your activities.
What kinds of issues arise when the degree of multiprogramming is so minimal?
The amount of memory that is free and may be distributed among running processes is the major component that determines the degree to which multiprogramming can be accomplished. If there is not enough memory, then the amount of multiprogramming that can be done will be restricted because there will be fewer processes that can fit in memory.
What are some ways that multitasking might be improved?
In practice, the CPU only executes one instruction at a time, but it is able to carry out instructions from any process that is now running. The example demonstrates that increasing the use of multiprogramming can result in better usage of a system’s central processing unit (CPU). Let’s say that the amount of time that a process spends disconnected from the CPU is denoted by the letter P.
What is meant by the term “deadlock condition”?
A deadlock occurs when many processes are unable to move forward because each process is now holding a resource and is waiting for another resource to be acquired by some other process…. When there are two or more processes that are holding certain resources and waiting for resources that are being held by other processes, an same situation arises in operating systems.
