The term "bug" to describe a computer error originated in 1947 when a moth got trapped in the Harvard Mark II computer, causing a malfunction. The technicians removed the moth, affixed it to their logbook, and wrote "First actual case of bug being found." This incident gave rise to the term "debugging" for fixing computer glitches.

The world's first website, created by British computer scientist Tim Berners-Lee, went live on August 6, 1991. It was a basic page that explained what the World Wide Web was and how to use it. This website marked the beginning of the internet as we know it today, and it paved the way for the explosion of online content and services that followed.

The concept of Augmented Reality (AR) dates back to the 1960s. In 1968, computer scientist Ivan Sutherland created the first head-mounted display system called the "Sword of Damocles." Although it was very basic compared to modern AR, it laid the groundwork for the development of augmented reality technology that we now see in applications like mobile games, virtual tours, and even medical procedures.
