What Is Computer RAM? Why is RAM called random access? How Does RAM Work?

Random access memory, commonly known as RAM, is a temporary storage location where data can be retrieved or rewritten in any order to support the real-time working of computer and mobile applications.
Without the ability to store and retrieve data fast, none of the applications or other functions would work properly. This is where RAM comes into play. RAM, or random access memory, is among the essential components of a computer system. It is a short-term memory bank wherein data that must be retrieved quickly is housed.
RAM maintains data readily available so that the central processor unit (CPU) may locate it without requiring it to access long-term storage to perform urgent processing duties.
RAM is included in all computing devices, including desktop computers (operating on Windows, MacOS, and Linux), tablets and smartphones (running on Android or iOS), and even internet of things (IoT) devices (like a smart TV).
RAM is also used to refer to a device’s short-term memory. It reads data that a program or operating system may need in the near future and temporarily stores it for easy access by the CPU, graphics card, and any other component that may require it. This information remains available in RAM until the application or device is closed or restarted. The RAM is then cleaned and prepared to accept fresh, appropriate data.
RAM prevents other components from accessing slower storage, such as a hard drive or a solid-state drive (SSD), whenever you open a new browser tab. While current storage is faster than older drives, it is still significantly slower than RAM. However, these storage components are required because they allow longer-term data storage whenever the RAM is not in full functional status.
