  2. Competency 003:The Master Technology Teacher knows and applies basic strategies and techniques related to web site mastering.

  3. A. The Master Technology Teacher: • Demonstrates knowledge of mechanism for navigating, accessing, transferring, sharing, and storing Web-based information across networks (e.g., the internet, intranets)

  4. Navigation: www.wordle.net

  5. Accessing • Definition: to use… • Uniform Resource Locator (URL) • Uniform Resource Indicator (URI)

  6. Transferring • It used to transfer data. • A protocol is the set of rules that describes how information is transferred across the Internet between clients and servers. The protocol used by the Web to transfer data is called the Hypertext Transfer Protocol (HTTP).

  7. The most common protocols are : • file://Opens a file on a mounted disk volume • http://Opens a World Wide Web page • ftp://Connects to a server using the File Transfer Protocol • telnet://Connects to a server using Telnet • news: Connects to a Usenet newsgroup • mailto: Sends an electronic mail message • snews: Opens a secure newsgroup connection • shttp://Opens a secure World Wide Web connection

  8. Sharing and Storing Web-based information across networks • local-area networks (LANs): The computers are close together in the same building/facility. • wide-area networks (WANs): The computers are farther apart and are connected by telephone lines or radio waves. • campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base.

  9. Internet / Intranet • An international network that most people refer to as the World Wide Web (www). • An intranet is a private network that is contained within an enterprise /company.

  10. Competency 003 – C The Master Technology Teacher: • Knows how to establish and access a folder/directory hierarchy for the management of a website and its related files.

  11. Folder/directory hierarchy for the management of a Web site and its related files • Electronic folders are used to organize the electronic data in the same way that the information is organized as in filing cabinets. • There are two types of links found in a web document: • Absolute links have paths that are prefaced by http:// and contain the full web address. • A relative address should be used for links to other web documents on the same server, especially when the files are all part of a larger project you are developing. Using relative addresses will also make your Web document more portable and easier to maintain.

  12. Competency 003: D The Master Technology Teacher: • Demonstrates knowledge of network, security, and access issue (e.g., firewalls, password controls) related to the maintenance of a Web site.

  13. Network

  14. Network • A group of two or more computer systems linked together. There are many types of computer networks, including: local-area networks (LANs): The computers are geographically close together (that is, in the same building). wide-area networks (WANs): The computers are farther apart and are connected by telephone lines or radio waves. campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base. metropolitan-area networks (MANs): A data network designed for a town or city. home-area networks (HANs): A network contained within a user's home that connects a person's digital devices.

  15. Network Topologies

  16. Security • To ensure that information that is stored in a computer cannot be read or compromised by anyone. • Passwords and data encryption are used as a security measure.

  17. Firewall A system designed to prevent unauthorized access to or from a private network.
