What Is The Difference Between (virtual)CT Colonoscopy, A Colonoscopy And/or A Sigmoidoscopy?

I am being asked by a medical group if I have had a (virtual)CT Colonoscopy, a Colonoscopy and/or a sigmoidoscopy. I do not understand the differences. I have had 2 procedures. One was through the anus and I was awake and watching on a TV monitor. The other I was asleep and a tube was put down my throat to ready me for a gastric-bypass.
