  2. 2. Etiquette in Technology
  3. 3. Etiquette Etiquette is a term that defined as “Something that relates to a code of behavior among people within a group, organization, or society”. It includes behavior expectations or norms within a society, social class, or group. Etiquette, by definition, is the concept of what is good, bad, right, and wrong. IT-WS01. NEUST
  4. 4. Netiquette Netiquette is a made-up word from the words net and etiquette. Netiquette thus describes the rules of conduct for respectful and appropriate communication on the internet. IT-WS01. NEUST
  5. 5. Netiquette Netiquette is often referred to as etiquette for the internet. These are not legally binding rules, but recommended rules of etiquette. Netiquette is mostly used for dealing with unknown people on the internet. The rules of netiquette very depending on the platform and its participants . Generally, it is up to the operator of a website or communication app to specify the type and scope of netiquette. It is also their responsibility to monitor compliance with these basic rules and to penalize violations of them. IT-WS01. NEUST
  6. 6. Here are the basics of netiquette and some of these guidelines may be repeated in various forms: • Writing in ALL CAPS in an online environment is the same as shouting. Do not SHOUT. Remember: The person on the other end of a digital communication cannot see your expression and hear your tone of voice. The basics of Netiquette IT-WS01. NEUST
  7. 7. • Cool off before responding to message in anger. You will probably regret what you wrote and it is hard to take it back once it is written and sent. • Check messages for misspellings and misstatements. • Respect each other’s privacy and your own • Use a clear and understandable email subject line. • Adjust your tone and style to the situation. The basics of Netiquette IT-WS01. NEUST
  8. 8. • Do not forward private messages to people they were not intended for or copy others on replies to personal messages. • Keep messages short and to the point. • No email is totally private – think of an email message as a postcard being sent through postal service. It is unwise to send very personal or sensitive information through email. The basics of Netiquette IT-WS01. NEUST
  9. 9. • A good rule of thumb to use with email is, do not put it in email if you would be embarrassed by your message being read out loud to your mother or grandmother in a crowd of people. • Pat attention to grammar and spelling. Though email is less formal than a report for class, people will form an opinion of you based on how you write. The basics of Netiquette IT-WS01. NEUST
  10. 10. • Sign all emails with your name to avoid confusion. Do not assume people receiving email will recognize your nickname ,or just a first name. • Before sending a message, consider whether you would say what you have written to the person’s face. The detached nature of email will sometimes embolden people to say things they would never say in person. The basics of Netiquette IT-WS01. NEUST
  11. 11. • Instead of hitting Send when you are angry or hurt, you may consider pressing the “Save to Drafts” button instead. You can then come back and open the message later to review it when you are calm, and then edit if necessary before sending the message. The basics of Netiquette IT-WS01. NEUST
  12. 12. • It is much easier to delay sending an email that it is to try to repair the damage from hurtful message. • If you really cannot help typing a furious response, do not send it immediately. Walk around the block, do some homework or watch TV, then reread your message and tone it down before sending. The basics of Netiquette IT-WS01. NEUST
  13. 13. • It is much easier to delay sending an email that it is to try to repair the damage from hurtful message. • If you really cannot help typing a furious response, do not send it immediately. Walk around the block, do some homework or watch TV, then reread your message and tone it down before sending. The basics of Netiquette IT-WS01. NEUST
  14. 14. • Pay careful attention to where your reply is going; do not hit “reply all” if you really only want to respond to sender. If a personal message ends up on a mailing list or listserv, it may be embarrassing for you and annoying for the other list members. The basics of Netiquette IT-WS01. NEUST
  15. 15. • You will invite spam to your inbox if your post your email address to random web pages. Only post your email on sites where your are registering to use a web tool, or trusted websites you use regularly. Do not use email address to enter contests or other drawing like events. The basics of Netiquette IT-WS01. NEUST
  16. 16. For Social Networkifig, keep this general tips in mind whenever you log on to different Social Media websites where you are posting or contributing to discussion: • Act like you would ifi real life. Just because you are hiding behind a computer does not mean that people are not going to connect what you say online with you are as a real person. How you act on social media sites is often the most direct way that people will perceive you. The basics of Netiquette IT-WS01. NEUST
  17. 17. • Be extra polite. You would not make nasty comment to a person you just met at school or work. In a face- to-face situation you had probably want to seem friendly and helpful. Apply same attitude to your social media activity. • Do fiot ask for favors. Once you have established with an online contact, you can ask for advice or help, but do not log on just to ask people to do your work for you. The basics of Netiquette IT-WS01. NEUST
  18. 18. • Follow the Goldefi Rule. Treat others the way you want to be treated, and you will develop a reputation for being a worthy friend. • Remember that there are boufidaries.

  22. 22. Internet
  23. 23. The Internet, also called the Net, is a global system of interconnected computer networks that use the standard Internet Protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic wireless, and optical networking technologies. The internet carries a vast range of information resources and services, such as interlinked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. Internet IT-WS01. NEUST
  24. 24. Internet A network is a group of two or more computer systems linked together. There are two main type of networks: • Local Area Network. A LAN is two or more connected computers sharing the resources in a relatively small geographic location, often in the same building. Examples include home networks and office networks. IT-WS01. NEUST
  25. 25. Internet • Wide Area Network. A WAN typically consists of two of more LANs. The computers are farther apart and are linked by telephone lines , dedicated telephone lines, or radio waves. The Internet is the largest Wide Area Network in existence. IT-WS01. NEUST
  26. 26. Evolution of the Internet Paper was the main medium used for information sharing and horses the main carrier for that medium. But science kept working, and in 1 8 3 1 Joseph Henry invented the first electric telegraph. Four years later, Samuel Morse invented the Morse Code, and worked on the very first long-distance electric telegraph line. IT-WS01. NEUST
  27. 27. Evolution of the Internet A bigger leap in communication progress was made by Alexander Graham Bell , who patented the electric telephone in 1876. Long distance communication was finally a reality, but still archaic compared to what was to be achieved. IT-WS01. NEUST
  28. 28. Evolution of the Internet With the arrival of computers in the mid twentieth century, people realized the potential of storing and processing data in those amazing new machines. Furthermore, the United States and the Soviet Union were deep in the Cold War, and the fear of a possible strike was constantly present. Prior to 1957, computers only worked on one task at a time. This limitation, called batch processing, was bypassed when the idea of time-sharing emerged. Timesharing allows for a single computer to be operated by multiple users at once. This discovery established the groundwork for information communication. IT-WS01. NEUST
  29. 29. Evolution of the Internet The origins of this method can be traced to the Defense Advanced Research Project Agency (DARPA) which was founded in 1958. One of DARPA’s first projects was to plan a large-scale computer network to increase the rate of information exchange. Scientists and researchers used it to communicate and share data with one another through what was known as DARPANET (Defense’s Advanced Research Projects Agency Network). This was in response to the Soviet Union bombings and a need to create a communication network which was free from interference and disruption. IT-WS01. NEUST
  30. 30. Evolution of the Internet The Internet began in 1969 as a project of the U.S. Department of Defense called ARPANET, or Advanced Research Projects Agency Network. The goal of this project was to design a nationwide computer network that could withstand major disasters. If one part of the network was destroyed, the other parts would continue to function due to the decentralized structure of the network. IT-WS01. NEUST
  31. 31. Evolution of the Internet In the Internet's early days (the 1960s and 1970s), only government, military, and educational institutions had computers connected to the Internet. The Internet was originally designed for research and scholarly communication. But as it grew, its services became more popular, and new ways of using the Internet multiplied. IT-WS01. NEUST
  32. 32. Evolution of the Internet By the end of the 1970’s, a computer scientist name Vinton Cerf had began to develop a way for all computers all over the world to communicate with each other with the use of “Transmission Control Protocol” or TCP. TCP/IP was described to be the “handshake” between computers all over the world. It enabled each computer to have its own identity. IT-WS01. NEUST
  33. 33. Evolution of the Internet In 1991,Tim Berners-Lee introduced the World Wide Web: an internet that was not simply a way to send files from one place to another but was itself a “web” of information that anyone on the Internet could retrieve. Berners-Lee created the first browser and the Internet we know today. IT-WS01. NEUST
  34. 34. The World Wide Web In 1989, Tim Berners-Lee presented the World Wide Web to the Conseil Europeen de Recherche Nucleaire (CERN; European Organization for Nuclear Research). The idea was to come up with a set of standards for information sharing that scientists around the world be able to use. IT-WS01. NEUST
  35. 35. The World Wide Web The goal was to be able to have all research documents in a format and location accessible to all interested regardless the platform being used. In 1994 the World Wide Web Consortium (W3C) was created to lead the World Wide Web to its full potential. IT-WS01. NEUST
  36. 36. The World Wide Web The World Wide Web (WWW), or Web, consists of a worldwide collection of electronic documents. Each electronic documents on the Web is called Web page, which can contain text, graphics, animation, audio and video. Additionally, Web pages usually have built-in connections to other documents. Some Web pages are static (fixed); others are dynamic (changing). IT-WS01. NEUST
  37. 37. The World Wide Web A Web site is a collection of related Web pages and associated items, such as documents and pictures, stored on a Web server. A Web server is a computer that delivers requested web pages to the browser. IT-WS01. NEUST
  38. 38. The World Wide Web A Web browser, or browser, is application software that allows users to access and view Web pages. It also interpret the page sent back by the Web server and display it on the monitor of the computer. IT-WS01. NEUST
  39. 39. Connecting to the Internet Many home and small business users connect to the Internet via a high-speed broadband Internet service. Examples of broadband Internet service include cable, DSL fiber, radio signals, and satellites.  Cable Internet service, provides high-speed Internet access through the cable television network via a cable modem. IT-WS01. NEUST
  40. 40. Connecting to the Internet  Fixed wireless, provides high-speed Internet connections using a dish-shaped antenna to communicate with a tower location via radio signals.  Cellular radio network, offers high-speed Internet connections to devices with built-in compatible technology or computers with wireless modems. IT-WS01. NEUST
  41. 41. Connecting to the Internet  A Wi-Fi (Wireless Fidelity), network that uses radio signals to provide high-speed Internet connections to compatible or properly equipped wireless computers and devices.  Satellite Internet service, provides high-speed Internet connections via satellite. IT-WS01. NEUST
  42. 42. How the Internet works? Computers connected to the Internet work together to transfer data and information around the world using servers and clients and various wired and wireless transmission media. On the Internet, the computer is the client that can access data, information, and services on a variety of servers. Internet backbone serves as major carriers of network traffic in the Internet. IT-WS01. NEUST

  44. 44. IT-WS01. NEUST
  45. 45. How the Internet works? The Web relies on these mechanism:  Protocols, set of standards used to access resources via the Web.  Universal Resource Locator (URL), uniform naming scheme for Internet resources.  HTML, document formatting language used to design most Web pages. IT-WS01. NEUST
  46. 46. How the Internet works?  CGI, Common Gateway Interface, is a standard way for a web server to pass a web user’s request to an application program and to receive data back to forward to the user.  Servlet, Application run by a server connected to the WWW. It is one of the most popular avenues for Java development today. IT-WS01. NEUST
  47. 47. Protocols Standard set of rules that governs how computers communicate with each other. HTTP (HyperText Trafisfer Protocol ) is the underlying protocol used to transmit information over the Web. HTTP is based on request- response paradigm: IT-WS01. NEUST
  48. 48. Protocols Connection: Client establishes connection with Web server. Request: Client sends request to Web server. Response: Web server sends response (HTML document) to client. Close: Connection closed by Web server. IT-WS01. NEUST
  49. 49. URL The Ufiiform Resource Locator or URL is the most recognizable part of the web. An example of a fully qualified domain name is www.veresoftware.com. A domain name is commonly used now to identify companies, market to individuals, and find your favorite site on the web. A URL starts with “http://,” which identifies the protocol to be used on the Internet and stands for hypertext transfer protocol. IT-WS01. NEUST
  50. 50. URL After the protocol usually comes the designator WWW, which we all know now stands for World Wide Web. Adding the WWW can be optional today because most browsers today will add the WWW. Additionally you may encounter WWW2 or WWW3 prior to a web address. These addresses and other prefixes can be used by an organization to identify other web content or websites, but don’t refer to any standards or Internet protocols. IT-WS01. NEUST
  51. 51. URL After identifying the protocol to be used, the domain name is the next significant part of the URL. The domain name is the registered name that identifies the location the browser will request information from on the Internet. A domain is formatted like veresoftware. At the end of the domain is the top level domain (TLD). IT-WS01. NEUST
  52. 52. URL TLDs are what the user commonly identifies as the end of the domain registration. The TLD identifies the highest level of the hierarchical structure of the URL. TLDs historically included the commonly recognized.com, .org, .mil, .edu. Over the past several years, mainly due to the increasingly diminishing English language domain availability IT-WS01. NEUST
  54. 54. URL Country codes will appear after the TLD as a designator of the country to which the domain is registered. Country codes are by standard a two letter code at the end of the URL. IT-WS01. NEUST
