Identify the correct sequence of the following computer storage components in the descending order of their access speed, from fastest to slowest.

CPU registers are the fastest store, sitting inside the processor itself.

Cache memory comes next, holding recently used data close to the CPU.

Main memory, the RAM, is slower than cache but still electronic and quick.

A magnetic disk is the slowest here, as it relies on spinning platters and moving heads.

The descending order of speed is thus registers, cache, main memory, magnetic disk.

Storage generally trades speed for capacity, so slower media hold far more data.
