Fastest to slowest:
CPU
Memory
Context switching
Disk
Disk access may be significantly faster at times due to caching ... so can memory access (CPUs sometimes manage a caches from main memory to help speed up access and avoid competition for the bus).
Memory access could also be as slow or slightly slower than disk access at times, due to virtual memory page swapping.
Context switching needs to be extremely fast in general ... if it was slow then your CPU could begin to spend more time switching between processes than actually performing meaningful work when several processes are running concurrently.
Register access is nearly instantaneous.
