A security objective can be described as a "statement of an intent to counter identified threats and/or satisfy identified organisation security policies and/or assumptions" (Common Criteria Project, 2009) and computer security is "the protection afforded to an automated information system in order to attain the applicable objectives of . Meaning of MIS 2. An Operating System (OS) is a software that acts as an interface between computer hardware components and the user. Device setting c. Turn off the system d. All of above. Give any five reasons. These hardware resources include processer, memory, and disk space and so on. 2) Efficiency: resources are efficient to use. 2.4. Design, implement, maintain, and evaluate internal control - easy enough, right? privilege and providing service calls that invoke the operating system kernel in high-privilege state. 4) File System. Different types of operating systems. The system itself is protected with a password. After studying this lesson they will be familiar with: 1. An operating system is a program that acts as an intermediate part between a user of a computer and the computer hardware and controls the execution of all kinds of programs.An operating system is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The COSO framework outlines three objectives, five components of internal control, and 17 principles related to internal control. This view is particularly clear when you look at Operating Systems . The following are the two different file system that is used to organize files in a computer system: File Allocation table After going through this unit, you will be able to: To introduce the notion of a process - a program in execution, which forms. Therefore, objectives of business should be defined keeping in view its prevailing environment and its needs for survival and growth. Convenience: An OS makes a computer more suitable to use. 2.6. Many definitions have been given for the term process , including A program in execution An instance of a program running on a computer Operating System Definition: It is a software that works as an interface between a user and the computer hardware. Operating System Concepts -9thEdition 2.3 Silberschatz, Galvin and Gagne 2013 Objectives To describe the services an operating system provides to users, processes, and other systems To discuss the various ways of structuring an operating system To explain how operating systems are installed and customized and how they boot What is an operating system? 3.0 Objectives. Click here if you want to go back to the A+ 220-1002 Core 2 Table of Content. . While the primary goal of some other operating system is efficient operation of the computer system. 1.
