Operating system From Wikipedia, the free encyclopedia Jump to: navigation search Operating systems Common features Process management Interrupts Memory management File system ... e An operating system OS ) is software , consisting of programs and data, that runs on computers and manages the computer hardware and provides common services for efficient execution of various application software For hardware functions such as input and output and memory allocation , the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware, but will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers Examples of popular modern operating systems for personal computers are Microsoft Windows Mac OS X , and GNU/Linux Contents Summary History Mainframes Microcomputers ... edit Summary Early computers were built to perform a series of single tasks, like a calculator. Operating systems did not exist in their modern and more complex forms until the early 1960s. Some operating system features were developed in the 1950s, such as monitor programs that could automatically run different application programs in succession to speed up processing. Hardware features were added that enabled use of

Ravish Sharma 06 Oct 2010 very good notes thank u.. The word operating system is not new to any computer literate. We all start our day with Windows and end by talking about Linux. We always argue about the performance and efficiency of one over other. Each of this is having its own limitation. Windows is a very good operating system used in almost every personal computer in this world. Whereas Linux is a great open source operating system which is totally free and is used in almost all web servers. Windows is nice but not free and Linux is free and open source but difficult to use. The main power of Linux is C language as it is totally developed in it, but the limitation of C language will definitely affect it too. Since last 30 years Linux is being developed and modified from its old variant UNIX, but now it is reaching to its limit. The size of the codes has increase so much that one global data created in wrong file can crash whole Linux. The day is not far when it will be impossible to add a single line of code without avoiding any ambiguity. So is this an end to a great free, open source operating system? There is always something new when something ends.

Without a computer operating system, a computer would be useless. Operating system types As computers have progressed and developed so have the types of operating systems. Below is a basic list of the different types of operating systems and a few examples of operating systems that fall into each of the categories. Many computer operating systems will fall into more than one of the below categories.

ZYRA home page Zyra's links page COMPUTERS SITE INDEX ... CATEGORIES COMPUTER OPERATING SYSTEMS A computer is a machine which consists of physical equipment AND the equally important virtual machinery, the basis of which is the Operating System. When getting a computer it is important to get the right hardware and the right Operating System. What's the best operating system? It's not the same for one person as the next. Choose something that is right FOR YOU. It's also worth noting that a computer can have more than one operating system on it. Mine currently (2001/01) has three. It is particularly important to make an informed choice and not to be fooled by hype into having the default just because it's fashionable at the time. Operating systems each have their own merits, and all have different good and bad points. The following is a list of operating systems available for the PC LINUX - It's UNIX on the PC and other computers. This makes any computer VERY MUCH more powerful. It's the opposite of the "dumbed-down" computing which is a current fad (2001/01). Linux gives YOU the power to do what you want, rather than just assuming you conform to some ordinary notion of a user. Linux makes your PC like a mainframe, and is especially good for programming . In my opinion this is very good. If you want to be in control, this is for you.

Our aim is to move beyond a simple conceptual familiarity with OS components to a deeper understanding of how such components are realized in a production-quality operating system. This will be a project-oriented course. We will use the

Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard , sending output to the display screen , keeping track of files and directories on the disk , and controlling peripheral devices such as disk drives and printers For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security , ensuring that unauthorized users do not access the system. Operating systems can be classified as follows: multi-user Allows two or more users to run programs at the same time. Some operating systems permit hundreds or even thousands of concurrent users. multiprocessing Supports running a program on more than one CPU multitasking Allows more than one program to run concurrently.

It is released under GNU General Public License (GPL). To view the GNU GPL click here or visit www.gnu.org . Ace OS is still under development and the development is more focusing on the Kernel concepts. Ace is developed from a scratch none of its module is copied from Linux or any other OS. Usage: Ace OS is developed for academic and research purposes. You can use Ace OS to study Operating System and Kernel Papers, because it is small and may be simple. Or you can use Ace OS for any purpose by modifing the source code. Development: Ace OS Kernel modules are developed by absorbing the interesting, easy, effective concepts used by other Operating Systems. Most of its concepts coming from Windows NT and some from Linux and other open source operating systems. Currently the development focus on the kernel. No application is developed until now (Except the Shell - which is technically a application). The kernel is developed using the freely available Assembly and C compilers - NASM, Mingw and DJGPP. The Architecture page contains the technical architecture of Ace OS.
