Operating Systems

Operating system development as a hobby has a large cult-like following. As such, operating systems, such as Linux, have derived from hobby operating system projects. The design and implementation of an operating system requires skill and determination, and the term can cover anything from a basic "Hello World" boot loader to a fully featured kernel. One example of this is the Minix Operating System-an OS that was designed by A.S. Tanenbaum as a teaching tool but was heavily used by hobbyists before Linux eclipsed it in popularity.

It is a computer operating system or a transparent pane to allow light to enter

If it is a windows OS, it will appear on the loading screen (something like xp, 95, vista...) If you want more details like the version or build number, go to my computer and click "View system information".

A multiuser operating system is one that allows several users to share a single operating system on a central server. An office/factory network may have several dumb terminals on which workers can input data using a keyboard. The IT manager is able to restrict or allow various workers to gain some or all of the operating system, based on what amount of access they need to do their job.

At the moment Android is growing the fastest given the number of android devices being manufactured. It has also penetrated the budget smart phone market with a number of manafacturers and shops already selling them between £49.99 and £100.00.

By right clicking on my computer and selecting properties and there you will find all the info about your computer. And you will find the operating system is installed on your pc.

False. All of the current generation of operating systems, including Windows, Linux, Android, iOS, Mac OS, Menuet OS, Haiku OS, Chrome OS, and many others all use a graphical user interface as their primary or only interface for the user to interact with. Linux can be configured to use a command line interface, but it is not the default for most any full-sized installation of Linux (e.g. any version of Linux that is installable, including many live CD/DVD setups, that are larger than approximately 100MB in size).

a. Register values

b. Heap memory

c. Global variables

d. Stack memory

Most people think of the operating system as the system software. The operating system is the most important software on a computer. It controls the computer's hardware and provides a platform for other software to run on.

Operating systems are complex and often have a lot of low-level code that is difficult to understand. They also have to be very reliable, as a crash can mean lost data or even physical damage to the computer.

yes, because maisha brown said so. if you have a problem come shake, all jokes aside.

Multiple user games are fun to play because you are interacting with other people, when playing over the internet with other users, being able to talk to other players makes the game feel more real. Also the fact that you might be better the other users in games such as "CounterStrike" makes you want to play on in hope that you will become better then friends and other users.

They defended their Internet browsers being installed with their operating systems by pointing out that the browser could not be sold separately.

The answer is the "shell." The shell takes two forms:

Command line interface (Like cmd.exe or BASH.), what is often just called a "shell" in many circles. You enter a command, arguments, or even construct entire strings of commands or scripts and the computer will, provided they are valid.

The other is the graphical user interface, examples are Aero, Explorer, Plasma Workspaces, twm, Quartz. Usually if you use your mouse and click on icons or menus to launch your applications rather than invocation from the keyboard.

Further, when you use application software you are also leveraging communication with the operating system. Any time your application needs to make any use of the hardware for any reason, it has to negotiate with the operating system to get services from the hardware. In modern operating systems, applications have zero control over the hardware, they usually have to tell the kernel when they need something outside of the CPU.

It depends on what you mean by "run the audio file copied from a CD." If you mean you copied a track straight off a CD onto your computer's hard drive then you have two choices: create a virtual CD-ROM drive to play the track; or, two, convert the audio file to a format the media player you have on your PC can play (mp3, wma, etc.). In either case you'll need special software to create the virtual drive or to convert the audio file for playing. If neither option is for you then you should still be able to play your audio CD from your CD-ROM drive using the default audio software that came with Windows.

a unit cell which do not contain any interior point is called primitive unit cell.and a unit cell which contain extra lattice point not at corners is called non primitive unit cell.

yes.

Multiuser multitasking is what many mainframe computers were set up to do after about 1965, when it was realized that a computer was sitting idle for most of the time, waiting for the next input to arrive. By setting up a number of different terminals, each with its own address, and its own interrupt number, several different users could be working with a computer at the same time, running different programs, which required the computer to perform different tasks, such as creating data tables, calculating values based upon variables that were input, reading records and assigning each different record a value based upon a calculation which used variables included in the records, and so forth. Multiprograming is what an operating system such as Windows, or the Apple OS for Macintosh does, as well as many Linux operating systems. Several different programs are loaded into a desktop computer, such as a web browser, mail program, games, image editor, etcetera, and they are all opened up and running at the same time. Of course, most desktop computers were not powerful enough until recently to be able to actually manipulate an image while browsing the internet while running a game. However, the newest generation of processors, which are clocking over 2 gigaHertz, can easily perform all of these functions without appearing to hesitate at all.

Distributed Operating System (DOS)

os for IBM

in fcfs scheduling there is a shortcoming

that is if any rocess of maximum brust time is first ome. and after that many short burst time process come. then smaller pocesses have to wait for a long time untill the max brust time process complete their execution.

in case of shortest job first it applied the method to give shortest t\burst time job to processer first.
