Why random character password is considered “weaker” than catchphrase with letters and symbols?

Answer 1

The logic is that you want a password which is easy for you to remember but hard for a computer to guess. Computers are excellent at guessing random letters and symbols, however you have a hard time remembering them. So you can only remember short passwords. The way human memory works makes it easier to remember places, actions and items rather then random characters. But there are so many possible words that computers have a very hard time guessing which words you used.
