A RAM cleaner is a software tool designed to optimize a computer’s performance by freeing up Random Access Memory (RAM) that may be occupied by unnecessary or idle processes. It scans the system for temporary data and background applications that consume RAM resources, and then terminates or clears them, allowing the computer to run more efficiently. This can lead to faster response times and smoother multitasking. RAM cleaners are helpful for maintaining system speed and responsiveness, particularly in cases where a computer may be slowing down due to excessive RAM usage, resulting in a more efficient and smoother computing experience.
