I mean, nowadays, secondary memories, like ssds, have become faster, not as much as primary, but imagine it being as fast as primary memory. Cpu and other components can access any byte of main memory by specifying its address. Secondary memory this type of memory is also known as external memory or nonvolatile. It comes in the form of computer chips that give fast and temporary storage for computer data. It is also called the internal storage, main memory or primary storage.
