Oval Hole on Your Laptop is For?

We know about most of the ports on  our laptops as we frequently use them.While some ports like HDMI are rarely seen these days, modern ports like USB-C are now pretty commonly seen. But wait, did you ever happen to question why there is an oval shaped port on your laptop? Sometimes you can find a “lock symbol” next to it and other times you may not.
Today we will see what the oval hole is for.

Ans:- It is called a Kensington Lock, or Kensington Security Slot, and it provides an attachment point for a cable to prevent your monitor (or a laptop as seen in the picture below) from being moved or stolen.

 The system consists of a small, metal-reinforced hole found commonly on small or portable computers and electronics equipment such as laptops, computer monitors, desktop computers, gaming consoles, and video projectors, combined with a metal anchor attached to a rubberized metal cable secured with a key or combination lock. The end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a heavy table or other similar equipment.
The hole is found in most laptops, although a lock for it is typically not included. Occasionally, the slot is located so that installing a lock will also prevent the removal of a valuable subcomponent, such as a rechargeable battery or a memory module. The Kensington slot may be marked with a small icon that looks like a padlock with a capital “K”, or the slot may be unlabelled.
