It would be devastating to most people to have their laptop or desktop computer stolen because of the vast amount of information stored on them and because of the security implications. There are many companies that sell computer locking systems. Most of these consist of a strong cable surrounded by a plastic casing with a lock on one end and a loop on the other. Almost every laptop has a built in slot on the back where you can attach the security lock. You would place the open cable end around a secure anchored post such as a desk leg or bed rail and feed the lock end through the loop to secure it. You would then place the lock in the appropriate slot on the back of the computer and press in until you hear it click. Most locks are either keyed or combination. Security is priceless when it comes to your personal information.
