IC3/Internet Fundamentals

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

Lesson Summary

 * The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.
 * The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, fault-tolerant communication via computer networks.
 * A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. The first web browser was invented in 1990 by Sir Tim Berners-Lee.
 * The most popular web browsers are Google Chrome, Microsoft Edge (preceded by Internet Explorer), Safari, Opera and Firefox.
 * Most major web browsers have these user interface elements in common: Back and forward buttons to go back to the previous resource and forward respectively, refresh or reload button to reload the current resource, stop button to cancel loading the resource, home button to return to the user's home page, address bar to input the Uniform Resource Identifier (URI) of the desired resource and display it, search bar to input terms into a web search engine, status bar to display progress in loading the resource and also the URI of links when the cursor hovers over them, page zooming capability, the viewport: the visible area of the webpage within the browser window, and the ability to view the HTML source for a page. Major browsers also possess incremental find features to search within a web page.
 * The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989.
 * The World Wide Web has been central to the development of the Information Age and is the primary tool billions of people use to interact on the Internet.
 * The terms Internet and World Wide Web are often used without much distinction. However, the two are not the same. The Internet is a global system of interconnected computer networks. In contrast, the World Wide Web is a global collection of documents and other resources, linked by hyperlinks and URIs. Web resources are usually accessed using HTTP, which is one of many Internet communication protocols.
 * Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization.
 * A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS).
 * Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols.
 * A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files.
 * A plug-in (or plugin, add-in, addin, add-on, addon, or extension) is a software component that adds a specific feature to an existing computer program. Well-known browser plug-ins include the Adobe Flash Player, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution on a local Java virtual machine.
 * In computer networks, to download is to receive data from a remote system, typically a server[1] such as a web server, an FTP server, an email server, or other similar systems. This contrasts with uploading, where data is sent to a remote server.
 * In computer networks, to upload is to send data to a remote system such as a server or another client so that the remote system can store a copy.
