Operating Systems

System programming or system software is a set of programs that co-ordinates the activities of hardware and programs. But OS meant it is a software that controls the computer hardware.

Linux is not an operating system but a kernel. Operating systems that are referred to as "Linux distributions" have a lot of common software, including mainly the Linux kernel, the GNU software and for most a graphical user interface (GUI) based on the X Window System.

The other software of the basic desktop environment (like office-software, web browser, file manager, PDF viewer, music player or audio player to randomly name a few) is mostly bundled and depends on the choice of desktop environment (like gnome, KDE, XFCE, LXDE to name the most widely used ones).

If the question is, which software will run on "Linux distributions", it is way to much to know it all.

If the question is rather, which software will NOT run on "Linux distributions" as opposed to the latest Windows or MacOS, this includes some software that is taylored for these systems (like the latest versions of MS Office, Windows Media Player, Internet Explorer, Safari etc.) and many new programs sold for profit including recent games. The reason for the latter is the small number of "Linux" users in comparison to Windows users, which makes it most profitable for software vendors to primarily aim for the Windows market.

Common operating systems:

Microsoft Windows (most recent version Windows 7)

Mac OS X (most recent version Lion) (needs Apple Mac)

Various Linux based operating systems (e.g. Ubuntu, Fedora, OpenSuse, Arch Linux, Debian, Mint)

Windows 2003 Server is the Best

The repeated execution of a loop of code while waiting for an event to occur is called busy-waiting. The CPU is not engaged in any real productive activity during this period, and the process does not progress toward completion.

On a "traditional" PC, the sort most homes have, running Windows operating system, when you power up the machine it runs through a boot cycle.

This includes:

The BIOS (Basic input/output system)

The BIOS' job is to check the hardware components of your machine, looking for harddrives, floppy drives, memory, keyboards, mice, processors etc... all the hardware components that make up a complete PC. It performs various checks, in many PCs this includes checking that the keyboard and mouse are attached. If they are not, the system grinds to a halt.

After the bios has run, it checks your main hard drive for an operating system "bootloader". If it can't find one, it will either prompt you to insert a CD or will again come to a grinding halt.

The Bootloader tells the machine what operating system you have installed, and where to look for it on your harddrive.

Once it finds your operating system, it will load up "driver" files.

Driver files make all your hardware work correctly. They are the bits of software that for example, tell your Monitor it should change resolution, or tell your modem to pick up the phone line and dial a number...

With windows (and other operating systems) there are driver files that are quite critical, and need to be loaded before the system can start. If they are missing or damaged the system will stop responding. At best, it may prompt you to enter "safe mode" where you can attempt to repair or replace these files.

Once all that is done, the main operating system loads the GUI. The Graphic User Interface - the screen and controls we are all used to.

Then its simply a case of selecting your user account and logging on.

On other computer equipment, these procedures may vary. But in general, thats how it happens.

• The OS must know specific information about processes in order to manage, control them and also to implement the process model, the OS maintains a table (an array of structures)

  , called the process table

  , with one entry per process

  .

• These entries are called process control blocks

  (PCB) - also called a task control block.

• This entry contains information about the process'state, its program counter, stack pointer, memory allocation, the status of its open files, its accounting and scheduling information, and everything else about

  the process

  that must be saved when the process is switched from running to ready or blocked state so that it can be restarted later as if it had never been stopped

It is commonly called "virtual memory".

The most important program that runs on a computer. 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.

Operating synergy arises from the efficiencies gained through the combination of companies or business units, leading to cost reductions and enhanced performance. Key sources include economies of scale, where larger operations can spread fixed costs over a greater output; improved resource allocation, optimizing the use of shared assets and capabilities; and streamlined processes that reduce duplication and enhance productivity. Additionally, shared best practices and knowledge transfer can lead to innovation and improved operational effectiveness.

Yes it is called Prism. I have it and it works very well.

I'm using a free Mac total video converter called snowfox total video converter for Mac, but it's free to try for 15 days, i got the register code from their giveawayoftheday.

Probably just a UNIX based with a GUI.
