How can I check for swap space? (4.8-Release)

[John Mills]

Freebies -

I just installed 4.8-Release from CDs and let the installer divide my disk 
automatically. Things are acting as though I have little or no active swap 
space.

1. What should I have gotten?

2. How can I check what I got? (No joy yet from 'fdisk' on that.)

3. How do I check current memory usage (sim. 'free' in Linux)?

TIA.
