The first question of this assignment is about computer software, what is difference between system software and application software, system software, application software.
WHAT IS MEANT BY COMPUTER SOFTWARE? DIFFERENTIATE BETWEEN SYSTEM SOFTWARE AND APPLICATION SOFTWARE.
Computer software:- Software is a generic term for organized collections of computer data and instructions, often broken into two major categories: system software that provides the basic non-task-specific functions of the computer, and application software which is used by users to accomplish specific tasks. System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk for matters, file managers, display managers, text editors, user authentication (login) and management tools, and networking and device control software.
Application software, on the other hand, is used to accomplish specific tasks other than just running the computer system. Application software may consist of a single program, such as an image viewer; a small collection of programs (often called a software package) that work closely together to accomplish a task, such as a spreadsheet or text processing system; a larger collection (often called a software suite) of related but independent programs and packages that have a common user interface or shared data format, such as Microsoft Office, which consists of closely integrated word processor, spreadsheet, database, etc.; or a software system, such as a database management system, which is a collection of fundamental programs that may provide some service to a variety of other independent applications.
Software is created with programming languages and related utilities, which may come in several of the above forms: single programs like script interpreters, packages containing a compiler, linker, and other tools; and large suites (often called Integrated Development Environments) that include editors, debuggers, and other tools for multiple languages.
Computer software is a general term used to describe a collection of computer programs, procedures and documentation that perform some tasks on a computer system. The term includes application software such • as word processors which perform productive tasks for users, system software such as operating systems, which interlace with hardware to provide the necessary services for application software, and middleware which controls and co-ordinates distributed systems.
“Software” is sometimes used in a broader context to mean anything which is not hardware but which is used with hardware, such as film, tapes and records.
DIFFERENCE BETWEEN SYSTEM SOFTWARE AND APPLICATION SOFTWARE:-
System software and application software are computer programs. The system software is also installed during the installation of the operating system. However, the application software utilizes the capabilities of the computer on which it is installed.
SYSTEM SOFTWARE:- The programs and the file that comprises the operating system are called system software. These files include configuration files, system preferences, system services, libraries of functions and the drivers for the hardware installed on the computer. The computer programs in system software include compilers, system utilities, assemblers, debuggers and file management tools.
Once you install the operating system, the system software is also installed. Program such “Software update” or “Windows update” can be used to update the system software. However, the end user does not run the system software. For example, while using the web browser, you don’t need to use the assembler program. System software is also called low-level software as it runs at most basic level of the computer. It just creates a graphical user interface thorough which the user can interact with hardware with the help of operating system. System software just runs at the back so you don’t need to bother about it.
The system software provides an environment to run application software and it controls the computer as well as the applications installed on the machine.
APPLICATION SOFTWARE:- The subclass of a computer program which utilizes the capabilities of computer is called application software. Application here means the application software and the implementation. The example of application software programs includes media players, spreadsheets and word processors. When multiple applications are packaged together then it is called application suite.
There is a common user interface in each application suite which makes it easier for the user to learn different applications. In some cases, such as Microsoft Office, the various application programs have the ability to interact with each other. This facility is very handy for the user. For example, a user can embed the spreadsheet in a word processor using the application software. Application software cannot run without the presence of system software.
DIFFERENCE BETWEEN SYSTEM SOFTWARE AND APPLICATION SOFTWARE
• System software gets installed when the operating system is installed on the computer while application software is installed according to the requirements of the user.
• System software includes programs such as compilers, debuggers, drivers, assemblers while application software includes media players, word processors, and spreadsheet programs.
• Generally, users do not interact with system software as it works in the background whereas users interact with application software while doing different activities.
• A computer may not require more than one type of system software while there may be a number of application software programs installed on the computer at the same time.
• System software can run independently of the application software while application software cannot run without the presence of the system software.
