  3. What Are We Going To Learn From This Section/Powerpoint? • Use browser software.

  4. What Is A Web Site? • A Website is a collection of Web Pages. • Example – EVHS’ website contains multiple web pages, such as the Staff Directory web page. • All the pages combined create a web site

  5. What Might You Find… • What kind of information is found on a website? • Product Information • News • Contact Information • About the Company • Prices

  6. What Might You Find… • How about the EVHS web site? • Grades • News • Contact Info • Information about the WASL test • Information about Sports • Etc. • Therefore, the site determines what kind of information you will find.

  7. Browser Software • A browser is a program that allows users to view Web pages and online information. • Just call it a web browser • Internet Explorer • Opera • Mozilla • Safari • Netscape Navigator.

  8. Remote Access • Intranet can be accessed from home via Remote access. • The employee uses his/her computer with a modem and a computer. • Some companies have remote access disabled. • Some manufacturers have remote access installed on their machines.

  9. Firewalls • What is a firewall? • Security system designed to prevent unauthorized access to a network. • Do we have a firewall at this school? How about on individual computers?

  10. Packets and You • Packets are simply small bundles of data sent over the Internet or a network. • Each packet contains information about where the data is going. • Packets fly across the net in different directions, looking for their destination.

  11. Packets and You • TCP/IP (transmission control protocol/Internet protocol) makes sure that packets are addressed and arrive properly. • When all the packets arrive, they are put together like a puzzle and displayed on your machine. • (If a packet is missing, TCP/IP lets the browser know so it can resend the packet) So.. Without TCP/IP, packets would simply sit in a digital pile with nothing to do.
