Basic Internet Concepts

History of the Internet

• The Internet was developed by a four month Defense Department contract that cost $19,800 on December 6, 1967 . From this study, ARPANET was developed which turned into the Internet.

• The work that led to working on communication technologies was because of the United States government response to the Soviet Union in 1957 because of Sputnik.

• The goal was to link information between different education and research institutions across the United States.

• ARPANET connected computers at Stanford, UCLA, UC – Santa Barbara, and the University of Utah.

• In 1987, the National Science Foundation took over the funding of ARPANET and then built a T1 line to connect the 5 supercomputers of the Nation together. This new and faster TI line became what is known as the Internet.

• The first formally sanctioned commercial email carriers were connected to the Internet in 1988 and the first public dial-up occurred in 1989.

Bookmarks, Favorites, Online organizers

created by the user and that serves as a shortcut to a previously viewed location (as an Internet site)” (merriam-webster.com)

Evaluation of Websites

• Just because something is posted on the Internet, does not mean it is a fact. One must evaluate the websites they are reviewing to determine if the information posted is accurate.

• The UC Berkeley Library created an 8 point evaluation checklist:• What does the URL tell you?• Who is the author? Are they of qualified authority?• Is it current or dated?• Is the information that is cited authentic?• Does the source have integrity and reliability?• Can you determine a bias?• Could the website be ironic?• If you have questions about the website, how do you solve them?

• Jim Kapoon listed the five criteria for evaluating websites to be accuracy, authority, currency, objectivity, and coverage.

Troubleshooting

• The Internet can be frustrating when it is not working correctly. Many issues can arise from slow Internet connections.

• Slow or no Internet connection can be caused by incorrect broadband router settings, interference with the wireless connection, or other technical issues.

-Incorrect broadband router issues• A problem with the broadband router can be caused if the MTU setting is too high or too low

because it can cause performance issues.• Router setting needs to be set the same as the manufacturer’s and the Internet Service

Provider recommendations.

-Wireless Signal Interference-Internet Worms-Running Background Applications -Faulty Network Equipment-Service Provider Issues
