What is the function of RAM in a computer?

The function of RAM, or Random Access Memory, in a computer is to serve as the computer's short-term memory. RAM temporarily holds data and instructions that the CPU (Central Processing Unit) needs while executing applications or tasks. This allows for quick access and processing since accessing data from RAM is significantly faster than retrieving it from storage devices like a hard drive or SSD (Solid State Drive).

When you run programs or open files, the relevant information is loaded from your computer's long-term storage into RAM, enabling the CPU to access it efficiently. Once the computer is powered off or restarted, the data in RAM is lost, which is why it's classified as volatile memory. This transient nature of RAM’s storage is crucial for tasks that require immediate data retrieval and processing, enhancing overall system performance and speed.

In contrast, permanent storage solutions, such as hard drives or SSDs, are designed for long-term data retention and are not as quick for access-related functions as RAM.
