Think of a hash as an irreversible transformation from "ILoveMyCatOscar1234" to "lkajsdv9a0vu0w9vjasva[wev9j[avasdvj;lasdkvasjv8ovasdvjasdga;sdfsd" (not a real hash, just an example)
When you sign up on a website, your password is not stored in their DB as a plain text password as you typed it - instead the "hash" is stored. Then when you login, it runs whatever you typed through the hash and compares that against the hash in the DB to confirm your login.
There are many reasons to do this, but one of the most obvious is to prevent people with DB access to know people's real passwords.
