Katerrian Lee Section 2 1. Please provide a short history of the Internet and how it was started. 2-3 paragraphs should suffice. The book speaks about this in chapter 2 page 28. What is the difference between Web 2.0, and Web 3.0? What is the purpose of the semantic web? During the Cold War between the United States and the Soviet Union in the 1950s and 1960s, each nation worked to improve its scientific and technology skills to avoid nuclear strikes from the other while yet remaining capable of striking the other. At the time, computers were much larger and could only do specialized functions. Researchers needed to be able to utilize computers to complete these functions, but they frequently had to travel vast distances to find a computer that could carry out a specific activity. Their only solution was to connect the computers so that they could communicate with one another, allowing researchers to share data without having to travel to the computer's location. The issue with this was that circuit switching, the mechanism of sending data from one computer to another, took a lengthy time and was easily disrupted. All the data had to be delivered in a single packet, and if the connection was lost at any point throughout the procedure, none of the data would be transmitted. Scientists devised a technique known as packet switching, which enabled data to be divided into smaller parts and transferred separately more rapidly without having to start the process over from scratch due to interruptions. When the data arrived at its destination, the packets could be reassembled into a whole packet. Packet switching allowed computers to communicate with one another via the ARPANET. This first network consisted of only four nodes, but more were added to allow research universities to exchange data and other resources. Eventually, other networks were created, but they could not connect with one another. To resolve this concern, the Transmission Control Protocol and the Internet Protocol were created. These principles enabled universal communication across all networks and ensured that packets transmitted over a network arrived at their intended destination. In 1991, the World Wide Web was launched. Using URLs, which serves as an address that directs the computer to the resource on the internet, users from any connected computer may locate resources and web pages on the Internet. The Web also employs HTTP, Hypertext Transfer Protocol, to allow users to obtain connected resources, as well as HTML, Hypertext Markup Language, to create web pages. Although the Web is frequently referred to as the internet, it is really a service that operates on the internet rather than the internet itself. The Web's generations differ in that Web 1.0 focused on connecting existing information, Web 2.0 grew to accommodate more dynamic content production and social engagement, and Web 3.0 detects data linkages. The Semantic Web's purpose is to augment the Web with a layer of machine-interpretable metadata from which computer programs may predictably generate new information. 2. What is a program ?

Katerrian Lee Section 2 A program is a predefined set of instructions for a computer to execute to process data. 3. What is the difference between data and information? Data is raw, unprocessed facts that are sent into a computer system, which produces compiled information when those facts are processed, whereas information is data that has been processed by a computer system. 4. What is cloud computing ? Cloud computing is a method of transferring computer tasks from a user's computer to servers on the internet by using the internet and the web. It also refers to data that is stored on a server on the internet and is accessible from anywhere the Internet is available. 5. What is a URL , a protocol, a domain name, and a web suffix? A URL is the address of a web page. A protocol is a set of procedures for exchanging data between computers. A domain name is a text string that specifies the address where a resource is located. A web suffix is the part of a domain name that comes after the dot and provides information about the type of organization to which the site is affiliated. 6. 98% of web surfers never leave the 1st page results after doing a simple search. This means if you never get into the top ten for your product, video, blog or other. The chances of your site getting seen are significantly reduced. What can you do to increase your chances of moving up in the search results? Please speak briefly how this might tie into what is called Search Engine Optimization and Search Engine Marketing. Online posts, appealing page titles, keyword-targeted website pages, and adverts may all help one move higher in the search results. Because heightened exposure attracts visitors to a website, there is an increase in search demand for it. This is related to Search Engine Optimization and Search Engine Marketing since they are processes that gather visitors from search results in search engines to improve a website's rank on search results pages. 7. What are some advantages and disadvantages when using Open-Source software versus Proprietary software? Please go to this site http://www.google.com/intl/en/about/products/ and explore and the explain how google derives their revenue from free applications. Explain the pros and cons to giving away free applications versus charging for them. How do you make a living if you give away free products? Add the terms proprietary software and open-source software to your glossary and define them. Open-Source Software

Katerrian Lee Section 2 Advantages: - no upfront cost - high reliability is ensured - no vendor lock-ins - can be scaled easily - offers convenient license schemes - mostly error free Disadvantages: - difficult to operate - security issues - some applications aren’t compatible - additional charge for maintenance - difficult to find required drivers - no extensive support Proprietary Software Advantages: - easy to use - exhibits stability - includes full rights to ownership - offers customer service - great source of revenue - has troubleshooting Disadvantages: - costly - lack of modifications - vendor lock-ins - sharing is prohibited - must wait for a team to fix errors - upselling Most of Google's revenue comes from Google Ads on free applications. These ads can be seen on YouTube videos or Google searches. Google targets relevant material directly to people by connecting ads to searches, resulting in billions of clicks. A click brings in anything from a few cents to more than $50. Google also makes money by charging extra for additional features on their free apps. For $4.99 per month or $29.99 per year, Google Play offers a Play Pass that grants access to hundreds of games and apps without ads or in-app purchases. For $11.99 per month, you may receive access to millions of YouTube videos without ad interruptions within the content via a premium subscription. Additionally, YouTube TV is a streaming television service offered by YouTube that has live television, on- demand media, and DVR options for $64.99 per month. Free Apps Advantages: - attracts more customers - doesn’t need to be complex - more likely to get positive reviews Disadvantages: - immense competition - lower customer loyalty - no guaranteed revenue
