What is Software?
Software refers to a set of instructions or programs that tell a computer what to do. It is a non-physical component of a computer system, also known as intangible or programmable components. Examples of software include operating systems, applications, and firmware.
- Operating Systems (OS): manage computer hardware resources and provide a platform for running applications.
- Applications: perform specific tasks, such as word processing, web browsing, or gaming.
- Firmware: permanent software stored in non-volatile memory, controlling device operations.
What is Hardware?
Hardware, on the other hand, refers to the physical components of a computer system. These are tangible parts that can be seen and touched. Examples of hardware include the central processing unit (CPU), memory (RAM), storage devices, and peripherals.
- Central Processing Unit (CPU): executes instructions and performs calculations.
- Memory (RAM): temporarily stores data and applications.
- Storage Devices: hold data and programs, such as hard drives or solid-state drives.
Key Differences between Software and Hardware
The primary differences between software and hardware are:
- Physicality: software is non-physical, while hardware is tangible.
- Functionality: software provides instructions, while hardware executes them.
- Upgradability: software can be easily updated or modified, whereas hardware upgrades require replacing physical components.
