How do you quickly close the current application window?
Depends on what operating system you are using. In Windows, Alt+F4 will close a window right away. Ctrl+Q will sometimes quit an application, which is better than closing the window itself. Ctrl+W will often close a sub-window in a multiple-document interface, or things like a single tab in Firefox.

What is relationship between a guest operating system and a host operating system in a system like VMware?
A host operating system is the operating system that is in direct communication with the hardware. It has direct hardware access to kernel mode and all of the devices on the physical machine. The guest operating system runs on top of a virtualization layer and all of the physical devices are virtualized. A host operating system should be as modular and thin as possible to allow the virtualization of the hardware to be as close to the physical hardware as possible, and so that dependencies that exist in the host operating don't restrict operation in the guest operating system.Read more: What_is_the_relationship_between_a_guest_operating_system_and_a_host_operating_system_in_a_system_like_VMware_what_factors_need_to_be_considered_in_choosing_the_host_operating_system
What operating system was used to run jurrassic park in the movie?
The park software is written in Pascal; a program is clearly visible in one of the monitor close-ups on the UNIX system. The graphical interface recognized as a UNIX system was the experimental Silicon Graphics 3D File System Navigator. The version number of the Silicon Graphics UNIX Operating System is 4.0.5 and is visible in one of the close-ups in the operating system's shell window (command program).

How are the operating system and application software related?
Simply put, the operating system is a set of software code assembled to have the hardware of a computer performing a series of basic tasks that, working in conjunction, will provide the many functions of the computing process, like reading a record from a disk, checking a field, opening a file, sending an instruction to a printer, etc.. It is normally written in a specific programming language, which relates to the low-level code required by the machine to be understood. An application software is a piece of code that runs on top of the operating system, collecting inputs from an operator/user, submitting these data to its internal rules for processing and delivering the corresponding results to an I/O (input/output) device - a monitor, a printer, a CD-recorder, etc.. It is normally written in a high-level language, familiar to programmers and offering several aids to make the programming easier. Several application softwares can be contained in a single computer and are activated every time a specific process is to be performed. Application software needs an operating system to have the machine running, because it sends its commands (open, write, read, close) to it expecting that they will be performed in that order, and that the operating system will return the information after being processed. In fact, the application software uses the operating system as an interface between itself and the hardware, to have specific jobs performed and results delivered.
What is open and close operating system?
A closed operating system is that does not allow you to have root access to the file system (ex. delete files or change files related to the graphical interface or how your computer does things)An example of this type of operating would be iOS which runs on iPod touches, iPhones, Apple TV, and iPad. An open operating system is the exact opposite of a closed operating system and is how all operating systems on a computer work which includes Mac OSX, Windows 7,XP, Vista, and Linux.
How operating system identify infinte loop in program?
OS can identify an infinite loop if an applications uses extra CPU and memory resources. If the application uses more resources than it is intended to use then the OS can close it down. This help computer from crashing.
What are system calls?
Call tracking devices will keep track of your calls. They can remember times called and durations of calls made and received.
How can you eliminate the possibility that an application error is caused by another application or service running in the background?
To eliminate background programs or services as a source of the problem, run the application after booting into Safe Mode. Press F8 at startup to display the Advanced Boot Options menu, and select Safe Mode with Networking from the menu. If the application works in Safe Mode, then you can assume the problem is not with the application but with the operating system, device drivers, or other applications that load at startup and are conflicting with the application.
What is the function of the Close button?
You have a Close button on a document and one on the application. The Close button on a document closes a document and will ask for the file to be saved if it has not been saved already. It will not close the application. The Close button on an application will close the application and ask for all files that are not saved to be saved. So there is very little difference between the two Close buttons.
How you close a window on a desktop?
A user can use the "X" icon on the upper-right corner of the application window, press Alt+F4 in most applications, press Alt, Space, C to close the application via the system menu, or right-click on the program's icon in the taskbar and choose Close.
