Internet

SLIDE 1   The Internet, linking your computer to other computers around the world, is a way of transporting content. The Web is (a protocol) that lets you use that content…or contribute your own. The Web, running on the mostly invisible Internet, is what you see and click on in your computer’s browser. Which came first? • Internet ~1972 (known then as the ARPANET) Advanced Research Program Agency Network • World Wide Web ~1990 • The WWW depends on the Internet The first supercomputers were designed to simulate explosions, crack codes and consolidate surveillance data. They were difficult to use, unconnected to other machines, vulnerable to attack, and accessible to only a few people. It made sense to build them into a network so that the power of their processing could be shared. In 1957, IBM began building the Semi-Automatic Ground Environment (SAGE), a system designed to coordinate defense against Soviet attacks from the air. When you use internet, your computer or device sends messages via these cables asking to access data stored on other machines. When accessing the internet, most people will be using the world wide web. t was originally created by the U.S. government during the Cold War. In 1958, President Eisenhower founded the Advanced Research Projects Agency (ARPA) to give a boost to the country’s military technology, according to the Journal of Cyber Policy. Scientists and engineers developed a network of linked computers called ARPANET.  The birth date of the internet is widely considered to be Jan. 1, 1983, but the road to creating it started long before the technology required for the internet even existed.   

SLIDE 2 The internet sends data around the world, across land and sea.   Then, it passes through local routers until it arrives at the computer with the matching IP address. The internet relies upon the two connecting computers  speaking the same digital language. Communication is something that has existed since the creation of humans until today, even after millions of years. The forms have changed, the types have changed, and the mediums have changed although communication in itself remains entirely the same. Communication, as compared to the prehistoric era, is different from the communication one has today. Earlier we can say that communication was limited. It was the interaction between two or more people; the conversations they had can be exclaimed as communication. Over time it eventually changed. One may ask that Isn’t communication still the same? Isn’t it still an interaction between two or more people? Certainly …Although there are different forms through which one can converse with the other. ommunication became even easier with the help of mobile phones. The mobile phone in itself was a major technology game charger. The introduction of touch screen phones and smartphones paved the way for improved mediums of communication. The required information was available to people in just a click.  The use of the internet is something that has made every person’s life easier and faster. Today no one can think of their life without the internet. The Internet helped in connecting with people regardless of time, or geographical boundaries. Not only for communicating with people; it was a medium that helped businesses to increase their pace in the moving world. Today another famous thing is E-mail. Today we can say that there are more than a billion users of e-mail. There will be no person who doesn’t have an email account. E-mail is something that has turned out to be so important that without it our lives would turn invaluable. Along with it came the latest trending game charger, social media. Every person today in this 21st century has a social media account on at least one platform. People spend their time heavily on their social media accounts. It has become an obsession for people today. It is something that helps people in sharing their photos, videos, etc on the platforms. So, would you say that social media has influenced communication? Certainly, social media has revolutionized communication.

SLIDE 3 ARPANET was the first and slowest network that used the internet protocols. CSNET was a slower network that connected more computers that were not on ARPANET. NSFNET was a faster network that replaced ARPANET as the main internet backbone.

SLide 5 www---used everywhere, not equals to the internet web has a  bunch of servers, each server is always connected to the internet and especially used to store and share information. website---renting a space in the web server where we can put information and link them to other info in an organized way. web hosts own web servers, anyone can set up a  web server. website address---we get lost without them,consists of the domain name. web languages get translated by the web browsers, which helps us by providing a graphic interface. before the web, we consumed the internet in a linear fashion which is not how our brain works, linking stuff, and hence Tim berners lee the father of the World Wide Web understood our need for interconnecting stuff.it is accomplished by the web where we use the hyperlinks to connect information,redirect to pages etc      

Slide 6 The web we are experiencing today is much different than what it was just 10 years ago. How has the web evolved? The evolution of the web is often partitioned into three separate stages: Web 1.0, Web 2.0, and Web 3.0. What is Web 1.0? Web 1.0 was the first iteration of the web. Most participants were consumers of content, and the creators were typically developers who build websites that contained information served up mainly in text or image format. Web 1.0 lasted approximately from 1991 to 2004. Web 1.0 consisted of sites serving static content instead of dynamic HTML.You can think of Web 1.0 as the read-only web. What is Web 2.0?    can think of web2 as the interactive and social web. In the web2 world, you don’t have to be a developer to participate in the creation process. Many apps are built in a way that easily allows anyone to be a creator. If you want to craft a thought and share it with the world, you can. If you want to upload a video and allow millions of people to see it, interact with it, and comment on it, you can do that too. Web2 is simple, really, and because of its simplicity more and more people around the world are becoming creators. Monetization of Apps Imagine the early days of popular applications like Instagram, Twitter, LinkedIn, or YouTube and how different they are today. The process usually goes something like this: Company launches an app It onboards as many users as possible Then it monetizes its user base security and privacy Web2 applications repeatedly experience data breaches. There are even websites dedicated to keeping up with these breaches and telling you when your data has been compromised. In web2, you don’t have any control over your data or how it is stored.  What is Web 3.0? There are a few fundamental differences between web2 and web3, but decentralization is at its core. Web3 enhances the internet as we know it today with a few other added characteristics. web3 is: Verifiable Trustless Self-governing Permissionless Distributed and robust Stateful Native built-in payments WEB3 web3 applications either run on blockchains, decentralized networks of many peer to peer nodes (servers), or a combination of the two that forms a crypto-economic protocol. These apps are often referred to as dapps (decentralized apps), and you will see that term used often in the web3 space. When you hear about web3, you'll notice that cryptocurrency is often part of the conversation. This is because cryptocurrency plays a big role in many of these protocols. It provides a financial incentive (tokens) for anyone who wants to participate in creating, governing, contributing to, or improving one of the projects themselves.   Imagine, instead, that a new and exciting project is announced that solves a real problem. Anyone can participate in building it or investing in it from day one. The company announces the release of x number of tokens, and give 10% to the early builders, put 10% for sale to the public, and set the rest aside for future payment of contributors and funding of the project. Stakeholders can use their tokens to vote on changes to the future of the project, and the people who helped build the project can sell some of their holdings to make money after the tokens have been released. People who believe in the project can buy and hold ownership, and people who think the project is headed in the wrong direction can signal this by selling their stake. In web3, Identity also works much differently than what we are used to today. Most of the time in web3 apps, identities will be tied to the wallet address of the user interacting with the application.   Glossary   Blockchain (noun) a publicly-accessible digital ledger used to store and transfer information without the need for a central authority. Blockchains are the core technology on which cryptocurrency protocols like Bitcoin and Ethereum are built. Centralized (adjective) a hierarchical structure in which authority and control are concentrated within a small group of decision-makers. Decentralized (adjective) a system that operates without the control of a central figure or authority, and replaces it with a distributed peer-to-peer network. Wallet (noun) a software application or hardware device used to store the private keys to blockchain assets and accounts. Unlike a traditional wallet, a blockchain wallet does not actually store the coins or tokens themselves. Instead, they store the private key that proves ownership of a given digital asset.
