2. Task Scheduling and Tasks Scheduler

3. What are the Operating System (OS) functions to the computer and application software

Answer 1

Task scheduling or Job Scheduling is one of the main functions of the operating systems. In this the OS allocates system resources such as memory to many different tasks that are to be completed and are waiting in the ready queue or job pool. The OS handles which jobs are of highest priority and how they will be scheduled to be completed and the amout of time that is required for their completion . Task scheduler are special system software which handle process scheduling in various ways. Their main task is to select the jobs to be submitted to the CPU and to decide which process to run. They decide the order of execution of different types of process such as high priority, input-output based etc. There are three types of schedulers:-- Long-term, Mid-term and Short-term Schedulers.

Functions of the Operating System :-

• Memory Management - manages memory by allocating and deallocating it to and from the process.
• Process Management - decides which process will be assigned to the CPU and for how much time.
• Device Management - manages devices connected to the hardware such as mouse,keyboard.
• File Management - manages files and folders it has into directories and sub-directories.
• Security - By means of password and other techniques it stops unwanted access.
• Error Detection
• It co-ordinates between other softwares and the users.
