Difference between Operating System and Application Software

A software is a set of rules or instructions that are given to a computer to perform some function. Basically, software is classified into two types Application software and System software. System software is the main software of a computer that has direct access to the system's hardware. It takes care and monitors all the other functions of a computer.

Application software is additional software in a computer which is used to perform a specific function. Users have direct access to this application software and this software is not mandatory in a system. We can use the system without this application software.

What is an Operating System?

An Operating System (OS) is system software that acts as a mediator between the user and hardware. It manages all the hardware components and provides an environment for the user to interact with various applications, execute programs, and use hardware components. The OS is the essential part of a computer system.

The OS is the first program to run when the computer is turned on. The BIOS starts running the operating system once the computer is started. It manages other application software, hardware devices, allocates memory, handles storage management, and more.

The main functions of an operating system are

• It provides an environment for the user to interact with the computer components and acts as an interface between the user and the system's hardware.

• It manages all the system resources and allocates them to the user based on their needs.

• It runs various other application software and manages their execution.

Types of Operating Systems

• Batch Operating System Processes jobs in batches without direct user interaction. Jobs are collected and executed sequentially.

• Time-sharing Operating System Each task is given a certain amount of time to execute. Once the time is completed, control shifts to the next task.

• Distributed Operating System Multiple computers are connected and share resources while appearing as a single system to users.

• Network Operating System Computers have their own operating systems and are connected to a common server for resource sharing.

• Real-time Operating System Designed to perform specific tasks within strict time limits. Used in critical applications like missiles and airbags.

What is Application Software?

Application software is a software program that can perform a specific task. This task can be business-related or personal. This software is accessed by the user and its sole purpose is to serve user requirements.

Application software is installed by the user based on their needs. Users can install multiple application software in their system and run them simultaneously. Examples include games like Candy Crush, web browsers, messengers like WhatsApp, and social media apps.

Types of Application Software

• Freeware Available for free without any cost. Examples include Adobe Reader, VLC Media Player, and LibreOffice.

• Open Source Source code is available for modification and enhancement. Examples include Apache Web Server and GIMP.

• Shareware Available for free for a limited trial period, then requires payment. Examples include WinRAR and Adobe Acrobat.

• Custom Software Specially developed for specific users or organizations. Examples include e-commerce solutions and fintech applications.

• Packaged Software A collection of related programs. MS Office is the best example, consisting of Word, Excel, PowerPoint, and Outlook.

Comparison

Key Differences

• Hardware Access OS has direct hardware access while application software accesses hardware through OS.

• Dependency Application software depends on OS to run, but OS runs independently.

• Resource Management OS manages system resources; application software uses allocated resources.

Conclusion

Operating System is essential system software that manages hardware and provides a platform for other software to run. Application software performs specific user tasks and relies on the OS for execution. While OS is mandatory for computer operation, application software enhances user productivity and functionality.
