In simple and short words, Softwares play a vital role in computer systems by creating a bridge between computer hardware and computer user.

Software is the mediator that connects the user with computer hardware.

You can say Hardware’s are the physical parts of a computer system and can be used in the system and by the computer users, for example- CPU (central processing unit).

Difference Between Computer Hardware and Software

Computer Software

We are already aware that computers need instructions to carry out the tasks, and they cannot perform themselves without any instructions.

When instructions are given to computers in a manner that computers can understand them and execute those instructions accordingly.

Such instructions to carry out certain tasks or tasks that are predesigned when made available in a computer-readable format are called programs. Such programs are called computer software.

These softwares can be stored in secondary storage devices such as (hard disks, cd-rom, etc) and make use of them as and when required.

Software is a set of programs that can be stored on a medium that is used to get the job done.

It plays an important and crucial role in all computer systems by creating a connection or bridge between the user and computer hardware.

The software needs to be checked before being used. There are some terms that are used for the process of accessing software including starting, executing, running, opening, and others.

Computer Hardware

Let’s understand this in easy language, Hardware is the physical and touchable parts of a computer means you can touch those components.

Internal hardware parts of a computer are known as components and external hardware parts of a computer called peripherals both of them are known as computer hardware.

In both PCs or desktop computers, the components of hardware are the same but there is a big difference in the size of the hardware.

Computers can only operate or start when both software and hardware are present and work together in the system, there is no chance to start a computer only with software or hardware.

You can enter the operating system by using operating software where hardware helps the operating software to perform fast and easily.

Types of Computer Software

Types of Software- Computer hardware and software

System Software

The system software is a collection of programs designed to operate the computer and control it.

System software performs the basic functions to start and operate the hardware components of the computer system.

They instruct the computer on how to operate its peripherals. In other words, system software deals with running the computer system or making it work.

There are two types of system software.

  • Operating system- An operating system or OS is a software program that deals with the functioning of the computer and its peripherals. It is the core software component of your computer. It is an interface between your computer and outside the world.
  • Utility Software- Utility programs are mainly intended as a helping aid and is provided by the computer manufacturer. These programs are also known as service programs. Such programs are available for call up by the operating system. It performs a specific task, usually related to managing a computer, its devices, or programs. It helps to manage the computer hardware and application software.

Application Software

The program that performs specific tasks for the users are known as application software or applications, Application Software has varied functional usages-

  • Application Software is a productivity business tool.
  • They assist in graphic communication tools.
  • It supports household activities and personal and educational programs.
  • It facilitates communication tools.

Application software is the main type of computer software. This software is used to edit text, graphics, and utilizes the capabilities of a computer for the completion of tasks.

Programming Software

This is commonly known and popularly used computer software. This software comes in the form of tools that helps all the programmer in writing programs for computers.

This is the sets of logical instructions that make a computer system perform certain tasks.

This is the tools that help programmers in instructing a computer system including a text editor, compilers, and interpreters.

Compilers translate source code written in programming languages into a language that a computer understands.

Compilers generate objects which are combined and changed into executable programs through linkers.

Debuggers are used to check code for bugs and debug it. This source code is partially or fully simulated for the debugging tool to run on it and remove bugs if any.

Interpreters execute programs, They execute the source code or a precompiled code and translate source code into an intermediate language before execution.

Functions of computer software

The main role of computer software is used to operate and manage the hardware resources of a computer. Some of the basic functions of the software are;

  • The software can make the computer to compare data, make logical decisions, do mathematical calculations, store and retrieve data and instructions from primary or secondary, and carry-out sequences of tasks.
  • The software enables computer users to obtain what they need from the computer.
  • Softwares make the computer to work towards giving the outputs in the manner the user wants it, such as output on a screen, printouts, sounds, sending emails, etc.
  • Some software is used to translate the program written in different or secondary languages into machine languages. These software are called ‘compilers’ or ‘interpreters’.
  • Compilers are the collection of large programs. It changes the high-level language into machine language.
  • Interpreters are the programs that are never compiled but their instructions are taken one by one.

Examples of Computer Software

What are the 4 types of software?

  • Operating software- DOS, UNIX, Microsoft Windows OS, Apple IOS and Apple macOS, Google Android OS, and Linux Operating software are examples of leading Operating software in the World.
  • Utility Software- File manager, disk cleaner, uninstaller, screen saver, file compression, virus scanner, and disk defragment are examples of utility software.
  • Application Software- Word processing software, spreadsheet, database, presentation graphics, accounting software, computer-aided design (CAD) software, video, and audio editing software, and many more these types of software are examples of application software.
  • Programming Software- JAVA, PHP, Notepad++, Visual Studio, Flosum, and UltraEdit are some examples of programming software.

Advantages and Disadvantages of Computer Software

There are too many software are available in the market for our ease, also in all sectors like Education, healthcare, home, finance, restaurant, railways, government, airlines and etc.


  • Software Increase Productivity
  • Analysis made easy
  • More accurate than the manual workforce
  • Less workload on the Human workforce
  • Increase consumer experience
  • Easy data handling
  • Calculation of large numbers made Easy
  • It reduces the cost of manual labor

Softwares are introduced to reduce the manual workforce. All software is made for their specific use. Benefits introduced by the software may be different for some sectors, it only depends on the type of work.

There are some disadvantages takes place in the market by using the computer software.

  • Softwares are expensive and need monthly updates.
  • Before being an expert you have to learn it and this takes 6-12 months for being the perfect touch on that software.
  • High-end software need high performing Laptops or computers
  • It also introduced some problems that are harmful to the computer and the data stored in it. (Computer Virus)
  • The data stored in computer software is likely to be theft easily by Hacking.

As always there are two sides of every coin, same as Computers software have also some advantages and disadvantages.
