The act of restarting a computer involves terminating all active processes and then initiating a fresh startup of the operating system. This process effectively clears the computer’s memory, reloads system software, and returns the machine to a known, stable state. A common example is when a computer freezes; a restart can often resolve the issue by forcing a fresh start.
The practice of restarting a system is beneficial for resolving software glitches, installing updates, and optimizing performance. Historically, it has been a primary method for addressing errors and maintaining system stability. The ability to quickly bring a system back online is vital for minimizing downtime and ensuring continued productivity.
