Ubuntu 12.04 is an example of a OS System software can be separated into two different categories, utility programs and operating systems. Operating systems are the foundation of your computer and almost every electronic device. G n berman reshebnik. The OS boots up the computer and makes sure everything is operational. The OS is also what runs your cell phone and most of your electronic devices.

The OS is, for the most part, the GUI (graphical user interface) that shows you all of your applications, and without the OS you cannot use the computer. There are many different types of OS’s which are discussed later. Utility programs perform a very specific task, to either enhance or manage your computer. For example your virus protection program, like norton, is an example of a utility program along with the install/uninstall program that comes standard with Windows. Systems Software vs Application Software [ ] Systems Software [ ] Systems Software are applications that are designed specifically for running the hardware on a personal computer and are used to maintain a platform for Application Software to be used. This means that systems software is designed to communicate with the internal parts of your computer such as the hard drive, RAM, ROM, cache, microprocessors, etc.

• Modern computer architecture implementation requires special hardware and software support. This includes; Distinguish between hardware and software parallelism. Mismatch problem between hardware and software. Fundamental concept of compilation support needed to close the gap between hardware and software. An operating system (OS) is system software that manages computer hardware and software. The dominant desktop operating system is Microsoft Windows with a market share of. Single-user operating systems have no facilities to distinguish users, but may allow. 'The evolution of the MVS Operating System' (PDF).

So that the user doesn't have to. It contains all of the drivers necessary for this type of communication and, in the simplest sense, it is the interface between the user and the hardware. The Operating System (OS) is not only one of the most important systems software on a computer, but is also the most frequently used.

It is the software that runs in the background and brings the separate physical parts of the computer together in order to provide the seamless stream of activity that a user experiences. Some of its responsibilities include the transfer of data between the memory and disks (on the hard drive) as well as providing the information needed to display icons, text, cursors and other visible necessities on the display screen.

This display is called the graphical user interface (GUI) and is entirely the result of the OS on the computer. This can be compared by viewing the differences between the Ubuntu OS and the Mac Snow Leopard OS. The icons between the two are positioned differently and they look different too. The Mac OS and GUI tends to have a more three dimensional aspect to it where Windows tends to appear more flat. It should also be remembered that the operating system conducts itself independently of both the user and any application software being used. This means that it is not directly dependent on the user or other programs in order to operate. Some other systems software would include BIOS and other device firmware.

These help the user interact with other utilities such as diagnostic tools, language translators, data communication programs, as well as data management programs. Mac GUI Application Software [ ] Application Software are the most common programs that run in the foreground of the computer. They tend to perform useful tasks which are not associated with computer maintenance, system boot-up, or hardware communication. Application software is directly reliant on the Systems Software to communicate to the physical components of the computer and cannot operate without it. If you were to visualize this, the Application Software would operate on top of the Systems Software and would be the most visible to the user while the Systems Software would remain in the background unnoticed.
