WHAT IS SOFTWARE?

 INTRODUCTION / What is Software?

Software is a generic term for organized collections of computer data and instructions, often categorized into two groups: 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. This chapter is dedicated to the discussion of various software types and the role they play in efficient functioning of a computer.

TYPES OF SOFTWARE

A computer system consists of hardware and software for its proper functioning.
Hardware represents the physical and tangible components of the computer i.e., the components that can be seen and touched. Input devices, output devices, CPU, floppy disk, hard disk etc. are examples of computer hardware.
Software represents the set of programs that govern the operation of a computer system and make the hardware run. Broadly there are two categories of software:
System Software
Application Softwar
Following sections discuss system software and application software in details.

SYSTEM SOFTWARE

A computer is mere a machine that knows nothing of itself. Rather it requires instructions for each and everything it performs. These instructions are provided to it through software. The software that controls internal computer operations (viz. reading data from input devices transmitting processed information to the output devices, checking system components, converting data/instructions to computer under standable form etc.) is known as system software. In short, system software is a specially designed software that controls the hardware and helps application software run properly
The System Software is a broad term and includes following types of software

Language Processor
Device Drivers
Operating System
Utility Software

Interpretation vs Compilation

  What is Interpreter? This language processor converts a HLL(High Level Language) program into machine language by converting and executing it line by line. If there is any error in any line, it reports it at the same time and program execution cannot resume until the error is rectified. Interpreter must always be present in the memory every time the program is executed as every time the program is run, it is first interpreted and then executed. For error debugging, interpreter is very much useful as it reports the error(s) at the same time. But once errors are removed, unnecessary usage of memory takes place as it has to be present in the memory always.   What is Compiler? It also converts the HLL program into machine language but the conversion manner is different. It converts the entire HLL program in one go, and reports all the errors of the program along with the line numbers. After all the errors are removed, the program is recompiled, and after that the compiler is not...
