Computer locks and anchors are security devices designed to protect your computer from theft. A computer lock typically consists of a metal cable or chain that is attached to a locking mechanism, which is then secured to a desk, table, or other fixed object. The cable is threaded through a slot in the computer case or a locking port on the computer, preventing the computer from being removed without unlocking the cable. A computer anchor is a similar device that attaches to a desk or other surface and allows you to secure your computer directly to the anchor using a locking mechanism. This provides an additional level of security and prevents someone from simply cutting the cable to remove the computer. These devices are commonly used in public places such as libraries, schools, and offices to prevent theft of laptops and other portable devices.
