You can obtain the password by brute forcing it without Rainbow tables however it will take a lot longer because the hashes are not precomputed. So for hashed passwords, you can use a program that compares every precomputed hash with the hash you're trying to crack and when it finds a match it finds what plain-text password the hash was created from and displays the plain text on screen - the password.
These files can vary in size you can get Rainbow tables specific to operating systems aswell to crack the passwords of the users stored on the computer. Rainbow tables are files containing precomputed hash values of plain-text passwords, they have every combination of certain characters up to a certain length.
How will you find your original password quickly? => Rainbow tables. So your friend runs moshi monsters and you've forgotten your password (idiot.), he checks his databases and finds the hashed value of your password: a5140b33be807008712c668cf5f30ce2. These hashes and encryptions are security measures so anyone that has access to the database will not see 'Password123', instead they will see ' 42f749ade7f9e195bf475f37a44cafcb' which is the MD5 hash value of Password123 (The encryption will not always be MD5 - On another note, if this is your password then I highly suggest changing it because if anyone has an interest in gaining access to your account then you're fucked. When a user enters their username and password into a forum website account etc, their username is checked for existence and if it returns true, then depending on the security system, the password they typed in is either hashed and compared with the password stored on the database, or the password on the database is decrypted and then compared with the password the user entered.
