Passwords

Most of us know in general what a password means and why is it used? Almost everyone of us has some or the other social account,or some bank account etc which we can access through passwords.

"A password is a secret word or string of characters that is used for authentication,to prove identity or to gain access to a resource"

Types of password:

A password can be broadly classified into two categories viz. BIOS password and System password.

1. BIOS(Basic Input Output System) is the first program which is run when a computer starts. A bios password is set at this level hence it prevents the system from starting if the correct password is not provided.
2. System password is of two types i.e user password and administrator password where user passwords are assigned to users on a single machine or domain  and different users may be granted different permissions.Administrator password on the other hand is assigned to the administrator of the machine who has all the power to make changes on the system and assign priviles to various users.
