Software is the programs and instructions that tell a computer or device what to do. Hardware is the physical equipment; software controls how it operates and helps people complete tasks. Operating systems, web browsers, spreadsheets and customer relationship management (CRM) applications are familiar examples.
But what exactly is software? At its core, software is a set of instructions that tell a computer what to do. It acts as the brain behind every digital device, enabling users to perform tasks, automate processes, and interact with technology.
This guide explains the main types of software, how businesses use them and the benefits and limitations to consider. For further background on how software is created and maintained, see IBM’s software development guide.
What is Software?
A set of programs, data, and instructions that are used to execute specific tasks with the help of a computer or device is software. Unlike the hardware, which is the tangible part of the computer, the software is an intangible code running on the machine.
Without software, each digital device ranging from smartphones to supercomputers would be a hollow shell incapable of performing anything meaningful.
What Is Software Used For?
Software has numerous applications, ranging from simple operations such as word processing to sophisticated applications such as artificial intelligence and cybersecurity. The following are some of the major application areas for software:
1. Operating Systems
Each computer, tablet, or smartphone requires an operating system (OS) to work. An OS, such as Windows, macOS, Linux, iOS, and Android, manages the hardware resources and allows the execution of applications.
2. Business Operations
It incorporates accounting, CRM, inventory management, and managing employees. Most businesses would grind to a halt without software; they would struggle to handle everyday operations.
3. Communication Enabling
With emails and video calls, the use of software such as Gmail, WhatsApp, Zoom, and Slack enables connection among people spread across the world.
4. Entertainment and Media
The media and entertainment range from Netflix and video games streaming services to audio streaming apps like music, through software.
5. Data Management and Analysis
Software assists companies in storing, processing, and analyzing large amounts of data. Examples include Microsoft Excel, Google Analytics, and databases that fuel decisions across industries.
6. Automation and Artificial Intelligence
Modern software solutions automate repetitive tasks, improving efficiency in manufacturing, healthcare, and customer service. AI-driven software may even learn and adapt to a user’s behaviour over time.
Types of Software
The software comes in different packages, each uniquely designed to perform a certain function. Here are the broad categories of software:
1. System Software
System software is the software that manages hardware and provides a platform on which other applications run.
Examples of System Software:
Operating Systems: Windows, macOS, Linux, Android, iOS
Utility Software: Antivirus software, file management tools, disk cleanup utilities
Firmware: Software installed on hardware equipment like routers, printers, and smart TVs
2. Application Software
Application software is used for particular tasks, such as writing documents, browsing the web, or editing photos.
Examples of Application Software:

Compilers: GCC (GNU Compiler Collection), Java Compiler
Debugging Tools: GDB (GNU Debugger), WinDbg
4. Middleware
Middleware is a piece of software that acts as an intermediary between several applications, providing them with ways to communicate with each other.
Examples of Middleware:
Database middleware helps applications connect to and work with databases, for example through database drivers or access layers. SQL Server and Oracle Database are database management systems, rather than examples of the connecting layer itself. IBM’s middleware overview explains its role in connecting applications and services.
API Middleware: Helps link software applications and services, for example, API Gateways

How to evaluate software for a business task
Define the job first. A marketing team tracking enquiries might need a CRM, while a team preparing monthly reports may need a spreadsheet or analytics tool. Write down the workflow, users and desired result before comparing features.
Check the full operating cost. Consider implementation, integrations, training, support and the ability to export your data, as well as the subscription price. Test the product with a representative task and agree what a successful result looks like.
Check the data as well as the tool. Software cannot make incomplete or inaccurate inputs reliable by itself. Read why data matters for business decisions for practical checks to apply before relying on a report.
