Moreover, they believe the labels on packages, e-mails they receive. In truth, those who do not trust much are considered pessimistic. Their opinions may be all rapidly disregarded or ignored. Likewise, the internet is also built on trust. In the mid 1960s, computers were very costly as well as slow by today?s standards but were still useful. In addition, to share the expensive and scare computers installed around the country, U.S. government funded a research project to join these computers put together; as a result, other researchers could utilize them remotely. This project was known as ARPAnet, which is named after the government research agency ARPA, the Advanced Research Projects Agency that funded and managed the project.

The thought was to make sharing ideas and resources simple and as capable as the technology of the day provided. But, only within the past few years, when Internet commerce always known as e-commerce began to increase, it has become scarce to rely mainly on trust. Since the days of the ARPAnet, they have altered the method we use computer networks while others have altered the essential technologies, all in an effort to develop the safety of the Internet.
