A run-on sentence is what happens when a writer tries to combine two or more independent clauses (complete sentences) into one sentence without the appropriate connecting words or punctuation; this is grammatically incorrect.
Example of a grammatically incorrect, run-on sentence: I sat at the back of the room the presenter stood at the front.
Here you have two independent clauses that are not separated by proper punctuation, so this sentence is a run-on sentence.
An independent clause is a group of words that can stand alone as a complete sentence:
I sat at the back of the room. The presenter stood at the front.
A compound sentence is what you get when you combine two or more independent clauses together with a conjunction (and, or, but) or a semicolon:
I sat at the back of the room, but the presenter stood at the front.
I sat at the back of the room; the presenter stood at the front.
