**What does "hardware" refer to in the context of computers?**
In the context of computers, **hardware** refers to the physical components that make up a computer system. This includes the central processing unit (CPU), memory (RAM), storage devices (e.g., HDDs, SSDs), motherboard, and peripherals like keyboards and mice. Hardware is essential for executing software instructions and processing data. Unlike software, which is intangible and consists of programs and applications, hardware can be physically touched and measured. The integration of hardware and software is vital for a functioning computer system.
