Why is RAM called random-access memory?

RAM is called "random-access memory" because the central processing unit (CPU) can directly and quickly access any specific piece of data stored in its memory, regardless of the sequence or location in which that data was recorded.12

Unlike sequential storage devices, where the system might need to scan through preceding data to reach a specific point, RAM organizes information into memory locations identified by unique addresses. This structure allows the CPU to retrieve or write information in a very short, consistent amount of time, as the physical location of the data does not affect the speed of its retrieval. This capability is essential for maintaining the responsiveness of active programs, as it provides significantly lower latency and higher data transfer speeds compared to permanent storage devices like hard disk drives or solid-state drives.213
