Students working at individual PCs in a computer laboratory send their files to be printed by a server that spools the files on its hard disk. Under what conditions may a deadlock occur if the disk space for the print spool is limited

Explanation:

Disk space is a limited resource on the spooling partition and once it is filled the will cause a deadlock. Every single block that comes into the spooling partition claims a resource, and the one behind that wants resources as well, and so on. Since the spooling space is limited and half of the jobs arrive and fill up space then no more blocks can be stored, causing a deadlock. This can be prevented allowing one job to finish and releasing the space for the next job.
