Short answer
Hardware is the physical machinery of a computer, while software is the set of instructions that tells the hardware what to do. Hardware performs the actual work, but software provides the logic and commands that enable functionality. 1 2
Hardware and software play separate but interdependent roles in computing; software directs hardware, but neither is fully functional alone.

What each thing is
Hardware. Hardware refers to the tangible, physical components of a computer system, such as the CPU, RAM, storage drives, and input/output devices, which enable essential computing functions. 1
Software. Software consists of intangible programs and instructions, including operating systems and applications, that direct hardware to perform specific tasks and manage system resources. 1 2
Key differences
The core technical distinction is that hardware is made up of physical parts—like processors, memory, and input/output devices—while software is composed of code and instructions that are stored and executed by that hardware. 1
How to tell them apart
You can recognize hardware by its physical form: you can touch a keyboard or see a monitor. Software, on the other hand, is experienced through its effects—such as a program running—but cannot be physically handled. 1
Where they overlap
Hardware and software overlap in their interaction: software must be loaded onto hardware to run, and hardware needs software to be useful. For example, an operating system (software) manages hardware resources like memory and storage. 1 2
Edge cases
Firmware is a tricky case because it is software (instructions) stored in hardware components, such as chips on a motherboard. It blurs the line by being both physically embedded and logically updatable. 1
Why the distinction exists
The distinction exists because computers require both a physical platform (hardware) and a set of instructions (software) to function. Each plays a unique role in enabling computing tasks, from basic operations to complex applications. 1 2
Common misconceptions
A common misconception is that software is only what you install, like apps, but even the operating system is software. Hardware alone cannot run programs without software to provide instructions. 1 2
Examples
When you press a key on your keyboard (hardware), the operating system (software) interprets that input and displays a letter on your screen. Both elements are necessary for this simple task to occur. 1 2
