The OS is a collection of many programs. It is already running on startup and does not need to be started again.
When you get this message on your computer, it means that whatever program you just tried to run, your operating system (Windows XP, Vista, Windows 7, etc.) is not compatible with it, so is not able to make the program run.
Operating system must be loaded first so that other applications and programs will be able to work.
At this stage, the BIOS still has primary control of the computer. It has loaded a program known as a "bootloader", which loads the operating system kernel (or another bootloader) and hands control over to it.
The DOSBox program is an emulator and acts as an operating system on your computer. Once you have everything downloaded and installed you are able to play DOS games.
To run a program without an operating system is a really difficult task. If one needs to type a document in a word processing program, one will have to create a code that will tell the computer to respond to each character pressed on the keyboard. Then one will have to write a code to tell the computer how responses must translate to the screen.
Check your operating system. You may have such a program.
The hardware requirements are what the Operating System designers have determined as the MINIMUM hardware to be able to run the Operating system. There are no minimum or suggested Software requirements for an operating system since the operating system IS the software.
There are a lot of games that do not work on "Vista" these are caused by incompatibilities between the versions of Microsoft's newest operating system and older versions. When a program is written it has to be able to communicate with the operating system on which it is being used. If the program was written before Vista was released there is always the possibility that it will not function correctly.
The first operating system or software is widely considered to be the program ENIAC, which was created in the 1940s by the University of Pennsylvania's Moore School of Electrical Engineering. ENIAC was the first large-scale electronic general-purpose computer and was used to solve complex calculations for the US military. The program used a variety of different software components, including a control program and an arithmetic unit. ENIAC was an important milestone in the development of software and was the first program to be able to manipulate data stored in memory. It was also the first program to introduce the concept of a stored program, which allowed for faster and more efficient computing.
The demands of a network operating system are to be able to share resources, and ensure network security.
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor.Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time. Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer
A kernel is a generic term to represent the core or base of an operating system. Since the operating systems mentioned here are very different, so are the kernels. They are written differently with different goals in mind. Having said that, no matter what kernel or operating system you are talking about a kernel program shares the same goals no matter what the vendor is. A kernel has to be able to handle booting the system, running tasks, managing resources, and other tasks as required by an operating system. The kernel is also the resident part of the operating system; it never gets swapped out of memory. Since its function is so important it has to be memory resident all the time.
