What is Software and How Does It Differ From Hardware?
Software vs Hardware
Software is a set of instructions that tells a computer what to do. Hardware is the physical parts. Neither works without the other. There are 2 types of software and 5 key differences between software and hardware:
Types of Software:
- System Software: manages the hardware and gives other programs a base to run on (e.g., Windows, Linux)
- Application Software: built for users to complete specific tasks (e.g., MS Word, Google Chrome)
Software vs Hardware:
| Aspect | Software | Hardware |
|---|---|---|
| Tangibility | Intangible; cannot be touched | Tangible; can be touched and seen |
| Role | Gives instructions and bridges user to hardware | Executes tasks as directed by software |
| Dependency | Depends on hardware to run | Cannot operate without software |
| Customizable | Can be updated without changing hardware | Physical changes require new parts |
| Examples | Windows, MS Word, Google Chrome | CPU, RAM, keyboard, hard drives |
Who coined “software”: John W. Tukey, American statistician, in 1958, in the journal American Mathematical Monthly.
What is Software?
Software is a set of instructions that tells a computer what to do. It sits between the hardware and the user. You cannot touch software, but the computer cannot work without it.
Software has two main types: system software, which runs and manages the computer, and application software, which helps users do tasks like writing documents or browsing the web.
Key Features of Software
- Intangible Nature: Software exists as instructions and code. It has no physical form, unlike hardware.
- Customizable: You can update or change software without changing the hardware.
- Functionality: Software lets users do tasks, from playing videos to controlling complex systems.
How is Software Different from Hardware?
Software and hardware work together to make a computer run. They serve different roles and have different features.
Major Differences Between Software and Hardware
| Aspect | Software | Hardware |
|---|---|---|
| Definition | A set of coded instructions or programs that run a computer. | The physical parts of a computer system. |
| Tangibility | Intangible; cannot be physically touched. | Tangible; can be touched and seen. |
| Interaction | Acts as a bridge between the user and hardware. | Executes tasks as directed by software. |
| Dependence | Depends on hardware to function. | Cannot operate without software instructions. |
| Examples | Operating systems (Windows, Linux), and apps (MS Word). | CPU, keyboard, RAM, and hard drives. |
Example: When you type on a keyboard (hardware), software like a word processor reads the input and shows the result on the monitor (hardware).
Who Coined the Term “Software” and When?
The term “software” was coined by John W. Tukey, an American statistician, in 1958. He used it in an article in the journal American Mathematical Monthly to describe the programs and instructions that control hardware. Before that, attention was mostly on physical machines. Tukey’s term gave a clear name to the intangible instructions that make hardware work.
A set of instructions that tells a computer what to do.
It has no physical form and cannot be touched.
Two types: system software (manages hardware) and application software (helps users do tasks).
Types of Software
Software falls into two main categories.
1. System Software
System software manages the hardware and gives other programs a base to run on.
- Examples: Operating systems (Windows and Linux), device drivers, and utilities like antivirus software.
2. Application Software
Application software is built for users to complete specific tasks.
- Examples: Microsoft Word for word processing and Google Chrome for browsing the internet.
Importance of Software in Computing
Software is essential in computing. It gives the instructions that make hardware work. Without software, parts like the CPU, RAM, and hard drives would sit idle. Software also lets users interact with computers through operating systems and everyday applications.
Software is intangible; hardware is physical.
- Software gives instructions; hardware carries them out.
- Software can be updated without replacing hardware.
- Hardware cannot work without software to direct it.
