To describe the services an operating system provides to users, processes, and other systems. To discuss the various ways of structuring an operating system. A program that controls the execution of application programs. An interface between applications and hardware. 2. Operating System Objectives. Convenience. Makes the computer more convenient to use. Efficiency. Eighth Edition. By William Stallings. Operating Systems:. Internals and Design Principles. System Access Threats. Intruders . Malicious Software. Programs that exploit vulnerabilities in computing systems. The programs that control and maintain the operation of the computer and its devices. The two parts of system software are the Operating System (OS) and utility programs.. Operating system (OS) (sometimes called the platform) coordinates all activities among computer hardware resources, applications and the user..
