Is the Canon EOS Rebel T2i a DSLR?

I was talking to an online representative on Wolfcamera.com and I told him if he would recommend any cameras to me hoping he'd recommend the Canon EOS Rebel T2i.
I said, "Are there any DSLR's you'd recommend for a first time DSLR user?"
He said he only has Nikon's and Sony's available, not any Canon's.

I asked, "Isn't the Canon EOS Rebel T2i a DSLR?"
He said it was an SLR.

Help?

I always had the impression it was a DSLR.

Answers please!

Yes, it is a DSLR.

Yes it is DSLR- a digital SLR

an SLR is a film camera

SLR uses 35mm film

DSLR is Digital.

So otherwise it's an SLR but it's a Digital Format Hence DSLR
