What is the main function of Random Access Memory (RAM)?

The main function of Random Access Memory (RAM) is to load open programs and current data. RAM is a type of volatile memory, meaning that it temporarily holds data that is actively being used or processed by the computer. When a program is run, it is loaded from the storage drive into RAM so that the CPU can access it quickly. This allows for faster processing since data in RAM can be accessed much more quickly than data stored on a hard drive or SSD.

While the CPU executes instructions that are stored in RAM, RAM itself primarily serves as a workspace for these programs and data in use. Once a computer is turned off, the information in RAM is lost, which emphasizes its role as temporary rather than permanent storage. This is why the function of managing file storage or permanently storing the operating system does not align with the role of RAM. In contrast, file storage is managed by the hard drive or SSD, while the operating system is installed on persistent storage rather than being held in RAM permanently.
