A sentence is a complete thought with a noun and verb.
A sentence fragment is just part of a sentence and does not make a complete thought.
The above are sentences.
Here are some fragments that make no sense:
the sentence fragment?
what is?
your answer in a complete sentence
the boy who lived down the street
because he had to go home
A fragment is not a complete sentence, a run-on is a sentence that can be separated into two sentences
Somebody will have to improve on this answer. One similarity between a sentence and a sentence fragment could be a sentence's length. If somebody says, "Who did that?" you could answer, "I did," and that is a sentence... but in a different scenario, that may be considered a sentence fragment. Why? Because if that sentence was all by itself, "I did," would be nonsense. What did "I" do? "I did jump," could then complete it.
