– Many software having a complex front-end may need techniques used in compiler design. A symbolic equation solver which takes an equation as input. That program should parse the given input equation. – Most of the techniques used in compiler design can be used in Natural Language Processing (NLP) systems. System Software – An Introduction to Systems Programming, 3rd ed., Leland L. Beck Chapter 5 – Compilers 5.1 Basic Compiler Functions z Fig 5.1 shows an example Pascal program for the following explanations. Z For the purposes of compiler construction, a high-level programming language is usually described in terms of grammar. Categories of Software. Compilers and translator programs. Enable programmers to create other software. Application Software. Software written to address specific needs to solve problems in the real world. System software. Software that manages a computer system at a fundamental level by coordinating hardware operations. System Software. We can compare, the computer system, hardware and software with human and human intelligence respectively. All the activities of human body like running eating, speaking are based on the thoughts and feeling raised by the brain. All these actions are initiated and controlled by our brain. 7 1.2 System Software and Machine Architecture System Software vs Application One characteristic in which most system software differs from application software is machine dependency. System programs are intended to support the operation and use of the computer itself, rather than any particular application. Examples of system software Text editor, assembler, compiler, loader or linker.

Software

Software is a set of programs, which is designed to perform a well-defined function. A program is a sequence of instructions written to solve a particular problem.

There are two types of software −

  • System Software
  • Application Software

System Software

The system software is a collection of programs designed to operate, control, and extend the processing capabilities of the computer itself. System software is generally prepared by the computer manufacturers. These software products comprise of programs written in low-level languages, which interact with the hardware at a very basic level. System software serves as the interface between the hardware and the end users.

Some examples of system software are Operating System, Compilers, Interpreter, Assemblers, etc.

Here is a list of some of the most prominent features of a system software −

  • Difficult to understand
  • Less interactive
  • Smaller in size
  • Difficult to manipulate
  • Generally written in low-level language

Application Software

Application software products are designed to satisfy a particular need of a particular environment. All software applications prepared in the computer lab can come under the category of Application software.

Application software may consist of a single program, such as Microsoft's notepad for writing and editing a simple text. It may also consist of a collection of programs, often called a software package, which work together to accomplish a task, such as a spreadsheet package.

Examples of Application software are the following −
