PSTN is the Public Switched Telephone Network.
This refers to what you can connect to. The "dial-up" that you mentioned utilizes this network (via modems), as do standard analog telephones as you'd see in a residential house.
These are typically called "POTS" lines (Plain Old Telephone Service)
So POTS lines utilize the PSTN. Make sense?
VOIP is a technology to run Voice Over IP....it is somewhat opposite of analog which carries pure voice natively.
VOIP calls can be sent over the PSTN if you have the right VOIP Gateway which essentially converts an IP call into the analog world..this also can be done by a VOIP provider in the cloud which has become extremely popular the last 3 years.
I hope this is helpful
