General Computing Definition
In a general computing context, software refers to the collection of programs, instructions, and data that tells a computer how to perform specific tasks. It is the intangible part of a computer system, contrasting with the physical hardware. Software can be broadly divided into two main categories:
System Software: This type of software manages and controls the computer hardware, acting as an interface between the hardware and the application software. It provides the foundational platform for other software to run.
- Key Concepts: Resource management, hardware abstraction, background processes.
- Examples: Operating Systems (e.g., Windows, macOS, Linux), device drivers, firmware, and utility programs (e.g., disk formatters, file managers).
Application Software: Also known as an app or program, this is the software designed for end-users to perform specific tasks that are not related to the basic operation of the computer itself.
- Key Concepts: User-facing, task-oriented, productivity, entertainment.
- Examples: Word processors (Microsoft Word), web browsers (Google Chrome), video games (Fortnite), graphic design tools (Adobe Photoshop), and mobile apps (Instagram).

Software Engineering Definition
In the context of software engineering and development, software is viewed as a product that encompasses more than just the executable code. It is a logical, rather than a physical, system element. From this perspective, software includes:
- Instructions (Code): The source code and executable programs that process data.
- Data Structures: The data that the programs manipulate, including its organization.
- Documentation: Descriptive information in both hard copy and virtual forms that describes the operation and use of the programs. This includes user manuals, technical specifications, and design documents.
- Configuration Files: Data used to set up parameters and initial settings for the software.
This view emphasizes that software is engineered, not just written, involving a systematic and disciplined approach known as the Software Development Life Cycle (SDLC).
Origin
Where it comes from.
Etymology
The term 'software' is a compound of 'soft' and 'ware'. 'Soft' was chosen to create a contrast with 'hardware'—the physical, rigid components of a computer. 'Ware' is a common suffix for products or goods (e.g., hardware, kitchenware). The term was coined to describe the non-physical, programmable, and easily modifiable aspect of a computer system.
Historical context
The conceptual foundations of software predate electronic computers. Ada Lovelace's notes on Charles Babbage's Analytical Engine in the 1840s are considered the first algorithm intended to be processed by a machine, making her the first computer programmer.
The modern era of software began with the advent of stored-program computers in the late 1940s. Early software was written in machine code, directly tied to the specific hardware it ran on. The 1950s saw the development of the first high-level programming languages like Fortran and COBOL, making software development more abstract and less machine-dependent.
The term 'software' itself was first used in a 1953 memorandum by Paul Niquette and later popularized in a 1958 article by statistician John W. Tukey. The 1960s and 1970s were marked by the 'software crisis,' where building complex software proved to be much harder, more expensive, and more time-consuming than anticipated. This led to the birth of the software engineering discipline.
The 1980s saw the rise of personal computers and commercial off-the-shelf software. The 1990s were dominated by the growth of the internet and the World Wide Web, shifting software from desktops to networked environments. The 2000s brought the rise of the open-source movement, Software as a Service (SaaS), and agile development methodologies. The 2010s to the present have been defined by mobile computing, cloud computing, and AI-driven software.
