# About IT Did you ever imagine that you can create your own page using the Internet? Do you find it exciting? Everyone can create their own page on the Internet. It allows you to promote yourself online. The good thing about creating your own page is you are allowed to be yourself. Your image and design is built on your own. Charles Leadbeater said, “You are what you share.” Explore the Internet and learn more than the basics. ## Know and Learn! ## What Is Internet? The Internet is alternatively referred to as “the Net,” a worldwide system of computer networks. It offers mass of information since millions of computers are linked within a huge network. Additionally, this is also called the Information Superhighway or Infobahn since information can travel back and forth to all computers that are connected to the Internet. Infobahn was a popular term used in the 1990s to refer to digital communication systems and the Internet telecommunications network. An example is when you download data using the Internet and send it to your relatives and friends through electronic mail.

TCP/IP is a new set of communications and networking protocols for managing data transmissions on the system. Nowadays, it remains integral to the Internet. - 1983: The Domain Name System (DNS) was invented wherein site names became easy-to-remember with names endings as .gov, .edu, or .mil. - 1985: The National Science Foundation (NSF) funded the construction of ARPANET’S biggest upgrade: the NSFNET, a command hub of five supercomputers that served as highways for all data traffic. - 1990: Tim Berners-Lee invented HTML, a text browser and graphical user interface (GUI) browser. He also established the first successful communication between a Hypertext Transfer Protocol (HTTP) client and a server via the Internet. These successful inventions make up the web pages as we know them today. Lee also came up with the term “World Wide Web.” - 1991: NSF initially allowed commercial industry to use the Internet. - 1994: A new world of e-commerce was born through Amazon by Jeff Bezos. - 1995: The National Science Foundation ceased funding the Internet and leaving it a completely self-sustaining industry. Sun Microsystems first released the most popular Internet programming language today which is Java. - 1998: Google opened its first office. - **2004-2005:** The social media revolution began when Facebook was launched in December 2004, followed by YouTube which debuted the following year. - 2006: “Cloud computing” was introduced by Google CEO Eric Schmidt. “The Cloud” became another synonym for the Internet soon thereafter. - 2007: The Internet is on the go through wireless connections. Mobile and smartphone technologies went commercial and grew rapidly. - **Present:** “The Internet will become ‘like electricity’-less visible, yet more deeply embedded in people’s lives for good and ill.” - Janna Anderson and Lee Rainee - Now, more people have access to the Internet and have it flow through their lives. - Mobile, wearable, and embedded computing are now tied together in the Internet of Things. Internet is widely used today by people to get connected through online social media, online chats, online forums, and video conferencing. ## Lesson 1 - Exploring the World Wide Web ## Activity 1.2: Word Storm Check what you have remembered on the history of the Internet.

WWW allows millions of web pages to be accessed instantly with a click of a button. These web pages can include text, colors, sounds, pictures, and videos. The web has three fundamental technologies that serve as its foundation: - **Hypertext Markup Language (HTML):** The markup or formatting language used to create pages on the web. HTML5 is the fifth and latest version of the HTML standard. - **Hypertext Transfer Protocol (HTTP):** It is a communications protocol. It is used to send and receive web pages and files on the Internet and the foundation of data communication for the World Wide Web. - **Uniform Resource Locator (URL):** This is a kind of “web address” that is unique and is used to identify resources on the web. The URL can be found in the address bar at the top of the web page. The illustration below is an example of a URL. **URL consists of three parts:** 1. **Protocol:** The protocol instructs how a web browser should communicate with a web server when sending or fetching a web page. 2. **Domain Name:** This identifies the organization that is directly responsible for the information. It is the web page that you are searching. 3. **Resource ID:** This is the name of the file for the page and any directories or subdirectories under which it is stored on a specified computer. ** http://www.example.com/index.html **[Diagram description]** A diagram displays the components of a URL. It includes three parts: Protocol, Domain Name, Resource ID, and a sample URL. **A URL can also be a series of numbers that works in the same way as the standard URL. Let’s go ahead and try. Launch your web browser and type the numbers below on your web address bar.** - Google: 103.233.36.167 - Facebook: 31.13.70.36 **The Internet has been revolutionized due to the invention of the World Wide Web (WWW). According to the website statistica.com, the Internet has grown rapidly with the number of users in 2015 reaching 3.17 billion.** ## Lesson 1 - Exploring the World Wide Web
