Random access memory (RAM) is the next level of storage that can be used to hold executing programs and/or data. RAM chips provide a higher amount of storage than the CPU cache and can improve computer performance. Storing data or programs frequently used in RAM can greatly improve performance as they can be retrieved faster than from the hard disk drives.

RAM is crucial for example when tuning your database management system to manage buffer cache. This involves storing frequently used database information in RAM for quick application access while being careful not to negatively affect overall operating system performance or the performance of other applications.
