What is the need for a strong password?

Now a days each and every website recommend or force us to use a strong password. Every website is most likely that they hash the password and store it in their database then what is the need for strong password if they are hashing the password or why is it required in first place. Is it the same with salted hashing also?

Because hackers try word lists and find out if they hash to the same value as stored in the database.

Weak passwords will be broken quickly, especially if no salt is used meaning that rainbow tables exist that allow lookups of the hash to find the password directly.

There is also the the threat of online attacks. e.g. an attacker trying every account against a web service login to see if they have password1, abc123, baseball, etc.

If you want a convenient way of having strong and unique passwords on every site you use, use something like https://lastpass.com

The reason for a strong password is because simple passwords can be more easily "unhashed" than a strong one. The larger character sets used in the password, and the longer the password it is, the harder it is to crack. Take a look at these videos as there is way too much information to discuss here:
