Placement strategies determine where in the main memory incoming programs and data should be loaded. Suppose a job waiting to begin execution has a memory requirement that can be fulfilled immediately. Should the job be loaded and begin execution immediately?
What will be an ideal response?
The naive answer is, “sure, why not?” But jobs have many more resource needs that
may affect whether or not they and the system can continue functioning properly after a new
job is loaded. Is the processor fast enough to handle another job?Are the various devices the
job may need available? Is the new job likely to require resources that existing jobs may need
in order to function effectively? Running this job may prevent later jobs from running efficiently.
By delaying this job, others may execute to completion quickly, enabling this process
to run without interfering with others.
