Random Access Memory (RAM)Random access memory, or RAM, is a type of computer memory that is used to store data and instructions that are being actively used by the processor. RAM is a volatile memory, which means that it loses its contents when the power is turned off. Unlike other types of storage, such as hard drives and solid-state drives, RAM can be accessed and written to quickly, which makes it suitable for storing data that the processor needs to access frequently. The amount of RAM in a computer can affect its performance, with more RAM generally resulting in faster performance. Most modern computers have at least several gigabytes of RAM, and some high-end systems can have hundreds of gigabytes of RAM or more.
