です is like saying "is" politely. だ is also "is", but you use it with friends. You use です when you need to be polite.
Watch out: You cannot say "ですない". This is wrong. To make "です" negative, you must use "ではありません" or "じゃありません".
Don't use this when you want to make an い-adjective past tense or negative. For example, you wouldn't say "おいしいですでした" (oishii desu deshita).
