the relationship between operating system and application software

Relationship between system software and application software? The most important type of system software is the operating system. Question: What is the relationship between operating systems and computer system helps to make computer hardware available to the application programs. Windows OS is an example of a pre-written software package. . F e 2: Relationship between Hardware, System Software and Application Software. igur . 1.

The diagram below illustrates the relationship between application software and system software. The most important type of system software is the operating system. According to Webopedia [], an operating system has three main responsibilities: 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.

Ensure that different programs and users running at the same time do not interfere with each other. Provide a software platform on top of which other programs i. The first two responsibilities address the need for managing the computer hardware and the application programs that use the hardware.

The third responsibility focuses on providing an interface between application software and hardware so that application software can be efficiently developed. Since the operating system is already responsible for managing the hardware, it should provide a programming interface for application developers.

Nutt [ 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. Nutt [] identifies four common types of operating system strategies on which modern operating systems are built: Batch This strategy involves reading a series of jobs called a batch into the machine and then executing the programs for each job in the batch.

This approach does not allow users to interact with programs while they operate. As shown in Figure 1, between the applications software and the hardware is a software interface - an operating system.

the relationship between operating system and application software

An operating system is a set of programs that lies between applications software and the computer hardware. Conceptually the operating system software is an intermediary between the hardware and the applications software.

Incidentally, the term system software is sometimes used interchangeably with operating system, but system software means all programs related to coordinating computer operations.

System software does include the operating system, but it also includes the BIOS software see the CPU chapterdrivers, and service programs, which we will discuss briefly in this chapter see Figure 2. System Software Note that we said that an operating system is a set of programs.

The most important program in the operating system, the program that manages the operating system, is the supervisor program, most of which remains in memory and is thus referred to as resident. The supervisor controls the entire operating system and loads into memory other operating system programs called nonresident from disk storage only as needed.

An operating system has three main functions: Keep in mind, however, that much of the work of an operating system is hidden from the user; many necessary tasks are performed behind the scenes. In particular, the first listed function, managing the computer's resources, is taken care of without the user being aware of the details. Furthermore, all input and output operations, although invoked by an applications program, are actually carried out by the operating system.

Although much of the operating system functions are hidden from view, you will know when you are using an applications software package, and this requires that you invoke-call into action-the operating system.

Thus you both establish a user interface and execute software. Operating systems for mainframe and other large computers are even more complex because they must keep track of several programs from several users all running in the same time frame.

Although some personal computer operating systems-most often found in business or learning environments-can support multiple programs and users, most are concerned only with a single user. We begin by focusing on the interaction between a single user and a personal computer operating system. Operating Systems for Personal Computers: An Overview If you peruse software offerings at a retail store, you will generally find the software grouped according to the computer, probably IBM that is, IBM compatible or Macintosh, on which the software can be used.

But the distinction is actually finer than the differences among computers: Applications software-word processing, spreadsheets, games, whatever-are really distinguished by the operating system on which the software can run.

Generally, an application program can run on just one operating system. The reason is that IBM personal computers and others like them have Intel-compatible microprocessors and usually use Microsoft's operating system, called MS-DOS for Microsoft disk operating system on older computers, and Windows95 or Windows98 on more modern computers.

Macintoshes use an entirely different operating system, called the Macintosh operating system, which is produced by Apple.

Over 75 percent of personal computers use a versions of Windows as their operating systems.

Macintosh comprises about 15 percent of the market, with other operating systems such as Linux comprising the rest.

Users do not set out to buy operating systems; they want computers and the applications software to make them useful. However, since the operating system determines what software is available for a given computer, many users observe the high volume of software available for MS-DOS machines and make their computer purchases accordingly.

Others prefer the user-friendly style of the Macintosh operating system and choose Macs for that reason. Although operating systems differ, many of their basic functions are similar. When the computer is turned on, the operating system will be loaded from the hard drive into the computer's memory, thus making it available for use. The process of loading the operating system into memory is called bootstrapping, or booting the system.
