What is the difference between hardware and software?

• A. Hardware is temporary; software is permanent
• B. Hardware refers to physical components; software refers to programs
• C. Hardware is user-installed; software is pre-installed
• D. Hardware uses electricity; software does not

Answer: (B)

The distinction between hardware and software is fundamental in understanding computer systems. Hardware refers to the tangible, physical components of a computer system—like the keyboard, mouse, motherboard, and hard drive—you can touch and see. These components are essential for the computer's operation, serving as the groundwork upon which software runs.

On the other hand, software embodies the programs and applications that tell the hardware what to do. This includes operating systems like Windows or macOS, as well as applications such as word processors or web browsers. Software is intangible and exists in the form of coded instructions that the hardware interprets to perform specific tasks.

Consequently, recognizing that hardware and software perform complementary roles within a computer system is critical. The hardware provides the necessary infrastructure, while the software enables its functionality, allowing users to interact with the computer effectively.
