Is the noun system a concrete or abstract noun?
Well, darling, the noun "system" is considered an abstract noun. Why? Because you can't touch, taste, or smell a system. It's all about ideas, concepts, and organization. So, there you have it - system is as abstract as your ex's excuses.

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??
