When a device intends to send a message to another device (for example, your PC sends a request to YouTube to open a video), it breaks the message down into smaller pieces, called packets.

Networking communication is full of some very technical concepts based on some simple principles. It is from this breakthrough that we first got the term Internet, which simply means “an interconnected network of networks.” TCP/IP quickly became the standard protocol and allowed networks to communicate with each other. So as long as your network supported TCP/IP, you could communicate with all of the other networks running TCP/IP. TCP/IP was designed to allow networks running on different protocols to have an intermediary protocol that would allow them to communicate. This problem was solved by the invention of transmission control protocol/Internet protocol (TCP/IP). Each network used its own proprietary language, or protocol (see sidebar for the definition of protocol), to send information back and forth. This led to a problem: the networks could not talk to each other. Different organizations were connected to different networks. During this time, other networks also came into existence. Over the next decade, the ARPANET grew and gained popularity. The first four nodes were at UCLA, Stanford, MIT, and the University of Utah. They began work right away and were able to complete the job just one year later: in September, 1969, the ARPANET was turned on.

Twelve companies responded to the request, and a company named Bolt, Beranek, and Newman (BBN) won the contract. In 1968, ARPA sent out a request for proposals for a communication technology that would allow different computers located around the country to be integrated together into one network. It was from ARPA, now called DARPA (Defense Advanced Research Projects Agency), that the Internet first sprang.ĪRPA was the center of computing research in the 1960s, but there was just one problem: many of the computers could not talk to each other. In response to Sputnik, the US Government created the Advanced Research Projects Agency (ARPA), whose initial role was to ensure that the US was not surprised again. In 1957, the Soviets surprised the US with the launch of Sputnik, propelling us into the space age. The US was in the depths of the Cold War with the USSR, and each nation closely watched the other to determine which would gain a military or intelligence advantage. The story of the Internet, and networking in general, can be traced back to the late 1950s. A Brief History of the Internet In the Beginning: ARPANET This chapter will review the different technologies that have been put in place to enable this communications revolution. Now, with the Internet a global phenomenon, it would be unthinkable to have a computer that did not include communications capabilities. In the 1990s, when the Internet came of age, Internet technologies began to pervade all areas of the organization. However, while the Internet and web were evolving, corporate networking was also taking shape in the form of local area networks and client-server computing. This ability for computers to communicate with one another and, maybe more importantly, to facilitate communication between individuals and groups, has been an important factor in the growth of computing over the past several decades.Ĭomputer networking really began in the 1960s with the birth of the Internet, as we’ll see below. During the 1980s, many organizations began combining their once-separate telecommunications and information-systems departments into an information technology, or IT, department. However, as the devices evolved, it became apparent that many of the functions of telecommunications could be integrated into the computer. In the early days of computing, computers were seen as devices for making calculations, storing data, and automating business processes.
