software lock that locks the keyboard until a correct password is typed in.

An integrated cable lock, sometimes referred to as the Kensington lock, can be used to secure your
computer to a desk, table, or other non-permanent xture. The cable lock attaches to a security slot at the
rear of your computer and is operated with a key. The cable lock also locks the computer cover. See Figure
