In plumbing, a trap is a U-, S-, or J-shaped pipe located below or within a plumbing fixture.
An S trap is not allowed in a plumbing system. Only a P-Trap
You don't as an S trap is self siphoning thus not allowed in most civilized codes

I'm assuming you are talking about a p-trap. A p-trap is a fitting that holds water to block sewer gasses from entering the building through the fixture. Every fixture with a drain has to have one in the waste. A toilet has what you would call an "s-trap" built into it. It serves the same purpose as a p-trap.

P trap
P-trap is to prevent gasses from passing thought the pipe. For example, in a residential setting, a p-trap is installed on all residential drains in order that sewer gases do not use the pipe as a conduit and enter the home.
A P trap exits horizontal from the back of the toilet and a S trap exits vertical from the bottom of the toilet.
