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.
You would either have to write your own loader or have the program compiled in such a way that it can load and map directly into memory (not an easy task in either case).
Then again, the program you are loading without an operating system would not be able to use any of the operating system resources (it couldn't depend on them being there).
A single program operating system allows only one program to run at a time.
Nope - the Operating System is a closed program. Applications run as independently as 'extensions' to the core Operating System.
No, Unix is an operating system program. A utility program cannot run by itself; it runs under an operating system.
windos7 is a operating system. without windos7 operating system the compuer can not work. windos 7 is the operating sytem that gives to program to run. all the program that can be created by the windos 7 like animation, vlc, movies , images etc.
A "Tasking" Operating System
Both are software, operating system is software that will make your computer boot up and run. while Application software is a program that will run on a functional operating system.
Yes, if it is a DOS program.
On the first computers, without an operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral-2like printers and card-readers. Not every computer had an operating system.
Program Execution means that you open or run a program installed at the computer. my question how to do program execution
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.
No. You need an operating system to do the installing.
Yes, the earliest computers built did not have operating systems (the idea of an operating system had not been thought of) so individual programs were loaded and run one at a time. The first computer I used (in 1973) had no operating system, programs punched on decks of cards were loaded and run one at a time. The first microcomputers sold did not have enough memory to load an operating system. When Bill Gates wrote the original version of Microsoft BASIC for the MITS Altair 8800 the standard 8800 came with only 256 bytes of RAM and Microsoft BASIC could not run with less than 4096 bytes of RAM (it was already very expensive to expand the RAM to that size), so Microsoft BASIC was written to run without an operating system. There are also embedded system computers that are dedicated to one purpose and usually run one preloaded program supplied by the manufacturer and do not allow other programs to be loaded. While some embedded system computers do use an operating system, it is also common for the preloaded program to be written to directly control all the hardware directly without the need for an operating system.
