THE INTERNET!

1. THE INTERNET! CYBERSPACE – HOW DOES IT WORK!?

2. TCP/IP Transmission Control Protocol/Internet Protocol • The TCP/IP model describes a set of general design guidelines and implementations of specific networking protocols to enable computers to communicate over a network. TCP/IP provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. Protocols exist for a variety of different types of communication services between computers.

3. IP Address Internet Protocol Address • An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there."

4. ISP Internet Service Provider • An Internet Service Provider is just what it sounds like; A provider of internet services. They connect you the the world wide web and allow you to access the internet. 3 examples would be: • Cogeco • Shaw • Bell

5. DNS Domain Name System • An often-used analogy to explain the Domain Name System is that it serves as a phone book for the Internet by allowing the looking-up of human-friendly computer hostnames where we find (or have found) the associated IP addresses in much the same way we look up a name in a phone-book to find the associated phone-number. With DNS we type the domain name into our browser address bar and the DNS looks up the associated numerical identifier or IP address. For example, the domain name www.example.com translates to the addresses 192.0.32.10 (IPv4) and 2620:0:2d0:200::10 (IPv6).

6. URL Uniform Resource Locator • A URL is the unique address for a file that is accessible on the Internet. A common way to get to a Web site is to enter the URL of its home page file in your Web browser's address line. However, any file within that Web site can also be specified with a URL. Such a file might be any Web (HTML) page other than the home page, an image file, or a program such as a common gateway interface application or Java applet.

7. Search Engine • A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are generally presented in a list of results often referred to as SERPS, or "search engine results pages". The information may consist of web pages, images, information and other types of files.

8. Cookie • A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is used for an origin website to send state information to a user's browser and for the browser to return the state information to the origin site.[1] The state information can be used for authentication, identification of a user session, user's preferences, shopping cart contents, or anything else that can be accomplished through storing text data on the user's computer.

10. Who Created the Internet? • The short answer is: no one person created the internet. The internet as we know it today is a compilation of the efforts of many, and to give the credit to one single person would be incorrect. Here is an article that lists a few notable individuals who assisted in the creation of the modern internet, and a description of their contributions. • http://www.computerhope.com/issues/ch001016.htm
