Computer jargon is not new, I’ve been in the computer business for over 40 years and we’ve always used jargon as a sort of shorthand in our communication. However, because of the Internet and the global discussion of computers, security and a multitude of other technology subjects; the world is now exposed to an immense amount of computer jargon. So here are some definitions to help you become knowledgeable on some of the more frequently used terms. Feel free to use them to impress your less-informed friends.

Every computer on the Internet is identified by a unique set of numbers known as an Internet Protocol address–usually four numbers separated by dots, for example: 22.214.171.124. These numerical addresses are normally invisible to users and are translated into familiar Web addresses, like http://www.google.com.
