The Internet evolved in the Defense From the 1970’s I wrote posts on Tyment and Telenet some of the very first commercial enterprise networks preceding today’s Internet. The Internet was born while the Internet Protocol Suite – Transmission Control Protocol/Internet Protocol was first standardized in the early 1980’s. Ever since then it has developed out of a text-based university study network with VERONICA and ARCHIE Disk Operating System (DOS) based programs on a PC into the Internet we know today.
To be part of this Internet a device has to be Physically linked to the Internet. This link can be a copper wire cable, optical fiber cable, and wireless radio station connection, a cellular wireless link, infrared light, or any other medium that can transmit digital transmissions (pulses of light or electricity) in some form. The device is a computer, tabletcomputer, cell phone, or some other device running programs that utilizes a hardware Interface to the Internet. Most likely the most widely used interface on Earth is a tarot card utilized in most computers. Each of Internet interface devices are assigned a few. This amount is really a 48-bit (or maybe now a 64-bit) binary number burned permanently into the device. The amount is known as a Medium Access Control (MAC) address. One time I purchased a very cheap Ethernet card made somewhere in Asia which had a MAC address of 00-00-00-00-01-76.
All internet communications use numbers. These amounts are Internet Protocol (IP) addresses rather than MAC addresses. Internet Protocol addresses are 32-bit amounts (and also 128-bit amounts ) ranging from 0.0.0.0 into 255.255.255.255. IP addresses may change, but a device tends to use the exact same speech on its own regional network over and over consistently. IP addresses are leased to devices.
Some devices encourage World-Wide Web (WWW or W3) sites. The heart of the World-Wide Internet is Hypertext files that are Linked together by links – references to relevant details on other WWW servers. The WWW was created n the early 1990’s. Prior to the WWW apps and Other info was shared using bulletin board computers. A bulletin board Computer was a computer that answered the phone and connected phoning Computers to programs and other information stored in its disk drive. It appeared Like at a flash of a couple of years bulletin board computers had been substituted by Internet sites on the Internet and the WWW internet abonnement.
