What were the main forces that led to the commercialization of the Internet? Summarize your answer in about 100 words.
Answer:
The Internet was born out of the need for the U.S. government, specifically the Defense Department, to communicate with its weapons installation distributions all over the world. This idea, in the hands of researchers and scientists evolved even further allowing those researchers the capability to communicate with their colleagues at other universities. As personal computers

The fourth considers the shift made, From ARPANET to Internet approaching defense and research. The fifth section covers The Internet in the Arena of International Standards. The final section, Popularizing the Internet, shows the beginning of the wide spread of the Internet but before Internet connectivity becomes popular at the personal level. All things considered, the book states the expansions in Internet history between 1959 and 1991, with some proceedings to 1994.
The internet has revolutionized the modern world like no other invention has before, except perhaps, electricity. The internet allows sharing and collaboration to take place between people on opposite sides of the globe. Vinton G. Cerf, often called the “Father of the Internet”, admits that when the original idea of an “intranet” was in its infancy, there was no possible way to imagine all of the ways we would come to use it (NDTV, 2013).
When Oprah gave away Pontiac G6 sedans to her TV audience, was the value of the cars taxable? On Labor Day weekend in 2006, World Furniture Mall in Plano, Illinois, gave away $275,000 of furniture because the Chicago Bears shut out the Green Bay Packers in the team’s football season opener at Lambeau Field in Green Bay (26-0). Was the free furniture in the form of a discount or rebate taxable, or should the furniture company have handed the customers a Form 1099-MISC?
It is important to know the history of the internet. The internet is a worldwide network of computer systems that are connected to each other by cables (Howe, 2012). The internet first started out as a military experiment. In 1957, the Advanced Research Projects Agency (ARPA) was created by the United States department of Defense (Computer History Museum, 2004). The project was started after the Russians launched a satellite into space for communication reasons. The satellite was called SPUTNIK (Computer History Museum, 2004). It was rumored that President Eisenhower got worried and decided to get the United States to launch its own satellite. They recruited Dr. Joseph C. Licklider of MIT, was made head of the Information Processing Techniques Office (IPTO)(Computer History Museum, 2004). Their purpose of the project was to focus on improving the military use of computer information.
The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

“The Internet-the vast network of telephone and cable lines, wireless connections, and satellite systems designed to link and carry digital information worldwide was initially described as an information superhighway.” (Campbell pg. 41). The Internet allows for ease in communication within e-mails, but it also guarantees the easy availability of information. Being able to access the Internet no matter the location is a great tool to have.
We will assume that Number Name where name is not unique (i.e., there may be more than one “John Smith”, each with a different student number). Then the multivalued dependencies are:
The Internet influenced the United States more than anything else in the 20th century. The Internet first technically started in 1969, when the U.S. Defense Department’s Advanced Research Projects Agency or ARPA connected networks at the University of California and the Stanford Research Institute (SRI). From there, just three years later the creation of the Email was born by Ray Tomlinson of BBN. With many other novelties of the Internet coming soon after, such as the Domain Name System (DNS) establishing .edu and .com, and the first web browser, World Wide Web by CERN. As the Internet flourished in the late 1990s it became more usable to the public and soon became routine to use, making great changes in society. The Internet was integrated
Over the course of the next twenty years it was mainly utilized by the United States military and government to communicate with each other during the “cold war” with the Soviet Union, and the allies of the United States. By 1982 the concept and use of the Internet had been reshaped by the Internet Protocol Suite (IPS). (CNN.org) The idea eventually evolved and was adapted by the United States in 1986, when the Internet Protocol Suite expanded and began to provide access to supercomputer sites for research and educational organizations. The internet further evolved by the mid-1990’s into the mass commercial use we see today, with many early use restrictions lifted. Since then the Internet has continued to expand and continues to advance. (Wikipedia.org)
14. Briefly describe three ways to connect to the internet. What are the advantages and disadvantages of each approach?
The internet was created more than 40 years ago. It was created on September 2, 1962 in L.A.. It was created by 2 UCLA computers ,and machines that were able to communicate with each other In its early days it was only used for communication during the Cold War. Sputnik , he very first satellite for the internet, was launched on December 4, 1957. One of the biggest factors to why the internet was created is ,because the U.S. feared one missile attack could destroy all telephone lines. The internet first message was sent in 1969. In 1969 only 4 computers were connected to the ARPA net, but it grew in the 1970s. The internet steadily became a public use in the 1980s. People started using it for communing with each other. The internet got worse and worse to use for research, so in 1992 researchers developed a program they called Mosaic. Mosaic was made to make browsing the internet safer and

From average teenager using the instant chat messaging to the businessman using the cost effective way to communicate within or outside the organisation Internet plays a key role. What is Internet? It’s a hard question to answer, as Internet is so many things to so many different people. It is a global network of interconnected networks of the computers, which provides the communication and information using standard protocol suite. Since the invention of the Internet it has changed the whole meaning of the communication. To fetch the information from one corner to different corner of the world is not a big deal now. Information passes in a matter of seconds these days. Communication and entertainment just isn’t the same ever since Internet was introduced. Internet has become everyday tool for billions of people all over the world these are the words that former President Bill Clinton said during his speech in 1996.”Internet” a biggest invention man could ever come across with.
Internet is a global network, connecting thousands of host servers worldwide. The United States Department of Defense established it in the beginning of the 1960¡¯s. Today, there are now 10 to 20 million people using an Internet comprised of more than 30,000 networks spread out over 78 nations all over the world.
