Computer Network Technology is the foundation of what makes of the Internet and allows devices such as computer be able to communicate between each other. Over the years computer network technology has drastically changed shape and who people are able to connect to the Internet as it known now.

History

The first known reference to computer network technology comes from the 1940 by George Stibitz who used a teletype machine to send information for a problem to his complex number calculator machine and be able to receive the results back the same way that they were sent. In the 1950's early networks utilized systems known as Semi-Automatic Ground Environment (SAGE) which allows data transmission to occur between radar systems. This early form of computer network technology was limited to government and military usage, however it paved the way for much of the future of computer network technology. In 1960 the first commercial airline reservation system utilizing the semi-automatic ground environment technology was able to two systems together to allow for communication for airline reservations between computers which was known as SABRE - semi-automatic business research environment. In 1962 the Advanced Research Projects Agency (ARPA) took interest in the connected network and with the hiring of J.C.R. Licklider he create what was known as a Intergalactic Computer Network, which was the first founding formation of network communication that the Internet has been built upon. Over the following decade a number of improvements and changes to computer network technology has evolved to create what is known as the Internet and allow the communication systems that are relied on by people everyday to properly function.

Computer network technology itself has drastically changed throughout history from military communication systems to large complex interconnected systems that power the Internet. One of the founding functions of computer network technology was the ability to send and receive information between two or more connected systems. The early development concept development of packet switching which was developed by Paul Baran and Donald Daives allowed for the transfer of data between two computers. This fundamental functionality paved the path for development changes in telephone switch technology and also for the future invention of the wide area network (WAN) concept to be born. In 1996 Lawrence G. Roberts published a paper called "Toward a Cooperative Network of Time-Shared Computers" that brought about the elementary concepts and approach to creating wide area networks and the Internet.

Broadband Computer Network Technology

In 1990 the idea of broadband began a new age phenom which allows people from their home to connect to the World Wide Web through home broadband connections. The early age of broadband technology utilized phone connection lines to be able to allow the user to dial into the Internet's connection. The first computer modem was created by Dale Heatherington and was known as the 80-103A model which offered people an automatic method to dial into the Internet. By 2001 home broadband connections became used mainstream and further helped develop faster connections. These new technologies that were developed and being brought into houses are still used in the current year. Technologies like Digital subscriber line and Cable Internet access helped expand and bring faster Internet connections to many homes throughout the United State and helped connect the world to each other through Internet connections. Digital subscriber lines are a form of computer network technology that works like a modem in that it relies on a phone connection to pass information over and be able to be connected into the rest of the network through an ISP. Cable line connections utilize the same form of technology as DSL, however they do not utilize phone lines instead they use cable lines to connect to hub facilities that are operated by the ISP to be connected into the network.

Future of Computer Network Technology

In the years after 2001 when broadband started to become main stream a number of evolution and changes in computer network technology occurred. With advancements in computer network technology networks were able to push faster connections to homes and a wider range of computer network technology became available to both home consumers and business of all size. Gigabit Ethernet has become a standard in computer network technology allow data to be transferred at 1,0000,000,000 bits per second. Furthermore the use of fiber optic cables to deliver faster home broadband connections has helped evolve computer network technology into a new age of digital speeds and further help expand the available of the Internet world wide.
