To respectively represent an http request and an http response. If you've never heard about that, you need to read some basics about the http protocol. There are some explanation at Wikipedia.

Did looking them up not help at *all*?! Is this an interview question? If so, I'm baffled for multiple reasons: if you're interviewing for a position for which you'd be asked this, I'd be concerned if you didn't know. If you didn't know, I'd be concerned you couldn't just look it up.

We should not discourage anybody.

Its part of HTTP protocol for communication between server and client.
