Question

Early versions of Windows did not support true preemptive multitasking. Instead, the designers of Windows provided something they called "cooperative multitasking" in which each program was expected to give up control of the CPU at reasonable time intervals, so that the Windows dispatcher could provide execution time to another waiting program. Describe the disadvantages of this method in several sentences.
2. There are some capabilities that are easy to achieve with a graphical user interface, but much more difficult with a command line interface. Describe at least three of these capabilities in a few sentences each.
3. You have noticed that loading the programs from your hard disk seems to take longer than it used to. A friend suggests copying the files from your disk, one at a time, to a different device, and back to your disk. You do so and discover that the programs seem to load much faster now. What happened? What alternative approach would achieve a similar result more easily?
4. Explain the first-in-first-out dispatch algorithm in several sentences. Discuss the advantages and disadvantages of this algorithm. Is this a preemptive or nonpreemptive algorithm?

Explanation / Answer

1.

which income no additional tasks are allowable to take the CPU time until this job preempts

this kind of functionality is missing in helpful multitasking

In the container of helpful multitasking, the reply time for the task is the best time span that can occur between a pair of calls to the root of the in service system called the most important part

but present are many situation that restrict this type of ceil or higher boundary time meaning

the developer or the coder has to physically create sure that the time hole flanked by subsequent calls to the root of OS( the kernel) are as low as possible

hence helpful is lesser than the preemptive.
