How does rebooting a computer resolve many common issues?

Rebooting a computer effectively resolves many common issues because it clears the system's memory and refreshes the operating environment. When a computer operates, it runs various processes and applications that can consume memory resources. Over time, this can lead to memory leaks or other issues where resources are not released or managed efficiently. By rebooting, the system memory is cleared, terminating all running processes, and resetting the operating system’s state. This helps eliminate temporary glitches, restore performance, and ensure that all necessary system files are loaded afresh, ultimately providing a more stable operating environment.

The other options do not accurately represent what happens when a computer is rebooted. Although rebooting can enhance performance through memory management, it does not increase physical storage capacity, optimize software, or delete files. Thus, understanding the effects of rebooting is crucial for troubleshooting and maintaining system performance.
