A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core. Diamond core bit is commonly used in construction to create holes for pipes, manholes, and other large-diameter penetrations in concrete or stone.
Exploration by drilling will result in a core sample. Brought up inside the hollow drilling tubes, the core sample is pushed out and is laid out for inspection and study.
Core drilling is usually done with a diamond tip drill bit. Diamond dust on the tip of these bits make it so you can drill through tough material such as concrete, masonry, or even tile. So to answer your question, there is not really a difference since they are essentially the same thing.

Core drills are used for several things such as when the core needs to be preserved or when the drilling can be done more rapidly because less material needs to be removed.

No, because the answer depends on what you are drilling through and why. Drilling a guide-hole through a wooden plank is somewhat different from drilling for an ice core in the polar regions or for minerals underground. So the question is so poorly specified as to be unanswerable.
