1. Briefly‚ what is an operating system? An operating system serves as a hardware/software interface‚ acts as a repository for common‚ shared routines and defines a platform for constructing and executing application software. 2. An operating system presents an application programmer with a relatively "friendly" hardware/software interface. What does this mean? Why is it important? The user interface‚ sometimes called the shell‚ provides a mechanism for the user and application programs to communicate

error or by a specific request from a user program that an OS service be performed .Dual-mode Operation allows OS to protect itself and other system components whereas Multimode Operation increasingly CPUs support multi-mode operations. System call provides the means for a user program to ask OS to perform OS tasks on the user program’s behalf. When a system callis executed‚ it is treated by H/W as a S/W interrupt. Timer protects CPU resource from getting stuck by a user program. To ensure OS maintains

Operating Systems Task 1 An operating system (OS) is a part of software which manages the operation of a computer. It controls the hardware and software of a computer‚ without it a computer would be useless. DOS Disk operating system (DOS) was released in 1981. It will load from a floppy disk each time a computer starts. DOS uses a command line interface. Command line interface can be difficult to use if you aren’t trained or experienced in using it. DOS is the predecessor to windows. DOS is

Operating System An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. It is a program designed to run other programs on a computer. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software
