Where exactly is the button?
We need to know the size (dimensions) of the button, too

Random Access Memory (RAM) Retrieve any data directly via
random access Sequential access is slow (e.g. cassette
tapes)

Hard drives
Traditional (mechanical) hard drive
What are solid-state drives? Are they better?
Are hard drives random or sequential access?
