Part 1: What Is RAM Cache Memory?

Generally, RAM stands for Random Access Memory, responsible for speeding up the data retrieval process from CPU to local storage disk, e.g., hard drive or SSD. RAM stores the data frequently accessed from the local storage, such as applications you use frequently.

The RAM prevents the CPU from retrieving data directly from the hard drive, which results in faster system performance and time efficiency. That’s why the increased RAM results in high performance, and the difference can be noticed in app opening.

However, note that the RAM is a volatile memory. The data stored in the RAM gets deleted automatically when you restart your computer. When you restart your PC, the same loop starts again; the data is fetched from the storage device.
