Paper Summary:
This paper explains that operating systems are primarily resource managers; the main resource they manage is computer hardware in the form of processors, storage, input/output devices, communication devices, and data. The author points out that it is important to understand that an operating system occupies the lower layer of system software; hence, it is always closest to the physical machine and, therefore, effectively manages both hardware and software by making use of its kernel. The paper stresses that security plays a fundamental role in an operating system, since it protects the OS from being destroyed or invaded.

Conclusion
From the Paper:
"A process in a multiprogramming system is said to be in a state of deadlock if it is waiting for a particular event that will not occur. "In a system, deadlock, one or more processes are deadlocked". In multi programmed computing systems, resource sharing is one of the primary goals of the operating system. When resources are shared among a population if users, each of whom maintains exclusive control over particular resources allocated to that user, it is possible for deadlocks to develop in which the processes of some users will never be able to finish."
