Random Access Memory (RAM)

Detailed explanation-1: -RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor. RAM is the main memory in a computer.
Detailed explanation-2: -Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request. The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM).
Detailed explanation-3: -Random access memory (RAM) close to the CPU. Contrast with “far memory, ‘’ which is farther away from the CPU. Near memory may refer to the cache memory in the CPU chip or to memory inside the CPU package. In all cases, near memory is closest to the CPU, and far memory is at a greater distance.
