PEEK and POKE were intended to be used with memory mapped devices. 
Simplest example is the 6502 chip, which had no I/O bus -- it was all
memory mapped.  Want to change baud rate?  poke a byte somewhere.

These days, the only device I can think of that's usually memory mapped
is the video.  And few programs talk to it that way.

Now, INP and OUT (or various similar names) were for doing port I/o. 
But I suspect that modern systems aren't going to let you do much of
that either.
