What is system view?
An operating system is a resource allocated a computer system has many resource that may be required to solve a problem: CPU time, memory space, file storage space and I/O device. A control program manage the execution of user program to prevent the error and improper computer it is especially concerned with the operation and control the I/O devices.
Why is the shell not part of the operating system itself?
Operating systems do 2 things: (1). Providing an easier abstraction layer (system calls) for user programs to access the real HW machine. (2). It manages the system resource. It this view, the shell is not considered as part of the operating system because: (1). It acts as a interpreter(from user command to system calls) only, and (2). It runs in user mode, and (3). It is highly possible to replace the shell if you don't like one.
What operating system do games use?
that depends upon the game, look for the games system requirements to view the operating systems prefered to run said game.
How an operating system manages multiprogramming?
An operating system enables you to view files saved onto your storage devices and arrange them into a folder/directory/file structure.
Difference between user view and system view of operating system?
User view: 1) the user view of the computer system varies by the interface being used. System view: 1)the operating system is a program that is most intimate with computer h/w. User view: 2)The OS is designed for "ease of use" some attention paid to none paid resource utilization. System view: 2)we can view an os is resource allocator. The os as act as the manager of the system. User view: 3) Some user sit at a terminal connected to mainframe or minicomputer. User share resources & may exchange information. That is designed for resource utilization. System view: 3)os was exist because they are reasonable way to solve the problems at creating a usable Computer system. The goal of pc is to execute user program and make solving problems easier.

System view of an operating system?
System View is a snap-in that lets you view what the computer is doing in real time.
How does an operating system manage a file system?
An operating system enables you to view files saved onto your storage devices and arrange them into a folder/directory/file structure.

Is Apple's Safari operating system safe to use on computer?
Safari is not an "Operating System". It is a web browser - an application or program which allows you to view information on the world wide web.
Do all computers need a operating system?
Basically Computer is the combination of both Hardware and Software.. So in order to support software we are in need of a Operating System.. This is my point of view..
What do you mean by abstract view of system?
abstract view of system means the overall view of system with its system components like hardware, operating systems and application programs like compiler, assembler, text editor, database system and so on. Above all has various users interacting with this system.
What are the different Views in operating system?
Three views of an operating systemApplication View: what services does it provide?System View: what problems does it solve?Implementation View: how is it built?Application View of an Operating System? The OS provides an execution environment for running programs.- The execution environment provides a program with the processor timeand memory space that it needs to run.- The execution environment provides interfaces through which a programcan use networks, storage, I/O devices, and other system hardwarecomponents.Interfaces provide a simplified, abstract view of hardware to applicationprograms.- The execution environment isolates running programs from one anotherand prevents undesirable interactions among them.CS350 Operating Systems Fall 2005Intro 1What is an Operating System??

Resources include processors, memory, disks and other storage devices,network interfaces, I/O devices such as keyboards, mice and monitors, andso on.? The operating system allocates resources among running programs. Itcontrols the sharing of resources among programs.? The OS itself also uses resources, which it must share with applicationprograms.Implementation View: The OS is a concurrent, real-time program.? Concurrency arises naturally in an OS when it supports concurrentapplications, and because it must interact directly with the hardware.? Hardware interactions also impose timing constraints.4Schematic View of an Operating SystemUser ProgramsResourcesresultsand datasystem calls system callOperating Systemcommands data and interruptssystem call interfaceIntro 1What is an Operating System??
