RAM (Random Access Memory) is a type of computer memory that is used to store data and program instructions that are currently being used by the computer's operating system and applications. It allows the computer to access and retrieve data quickly, which helps to improve the overall performance and speed of the system. RAM is a temporary storage space and is cleared when the computer is turned off.

RAM (Random Access Memory) is a type of computer memory that stores data and instructions that the CPU (central processing unit) needs to access quickly.
Functions of RAM:
- Stores temporary data and instructions: RAM holds the data and instructions that the CPU is currently processing.
- Provides fast access: RAM is designed for fast read and write operations, allowing the CPU to quickly access the information it needs.
- Bridge between CPU and storage: RAM acts as a bridge between the CPU and slower storage devices like hard drives and solid-state drives (SSDs). When the CPU needs data or instructions from storage, it first loads them into RAM for faster access.
- Enhances processing speed: By providing faster access to data and instructions, RAM significantly improves the overall processing speed of the computer.
- Allows for multitasking: RAM allows multiple programs and applications to run simultaneously by providing them with the necessary space to store their data and instructions.
- Caches commonly used data: RAM can store frequently used data and code in a dedicated area called the "cache." This reduces the need to repeatedly fetch the same information from storage, further enhancing performance.
Types of RAM:
- Static RAM (SRAM): Faster and more power-efficient than DRAM but more expensive and less dense.
- Dynamic RAM (DRAM): Less expensive and more dense than SRAM but requires constant refreshing to maintain stored data.
Capacity and Performance of RAM:
- Capacity: The amount of data that RAM can store is measured in gigabytes (GB) or megabytes (MB). Higher RAM capacity allows for more programs and data to be loaded into memory simultaneously.
- Speed: RAM speed is measured in megahertz (MHz) or gigahertz (GHz). Higher RAM speed means faster data transfer rates and improved system performance.
