way around a computer system to gain unauthorized access to its data or take
advantage of it. Hacking here does not just mean, being able to break the
password to gain access to it.
Gaining access to a local PC secured by BIOS passwords:
BIOS stands for Basic Input Output System and is type of non-volatile
firmware stored on a chip on the motherboard.It comes Pre-installed by the
manufacturer and is the first program that runs when we start the computer .It
performs hardware initialization and performs the flow of data between the
operating system and the devices attached like a mouse,printer,keyboard etc.
A BIOS password is one of the most basic ways of securing a PC. It is the
information required to log into a computer's BIOS before it starts to boot up.
