Introduction to internet with windows 7 changes

  2. 2. WHAT IS THE INTERNET?  The Internet, sometimes called simply “the Net,” is a worldwide system of computer networks—a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometime talk directly to users at other computers). 2
  3. 3. E-MAIL  Electronic Mail (e-mail) is the most widely used application on the Net. Electronic mail, commonly called email or e-mail, is a method of exchanging digital messages from an author to one or more recipients. 3
  4. 4. CHAT  Another popular feature of the Internet is you can carry on live “conversations” with other computer users, using Chat.  Chat is real-time communication between two users via computer. Once a chat has been initiated, either user can enter text by typing on the keyboard and the entered text will appear on the other user's monitor. Most networks and online services offer a chat feature. 4
  5. 5. CHAT –ABBREVIATIONS AND MEANINGS  <3 heart 404 I haven't a clue  A3 Anyplace, anywhere, anytime ADN Any day now  AFAIK As far as I know AFK Away from keyboard  ARE Acronym-rich environment ASAP As soon as possible  A/S/L?

  6. 6. WORLD WIDE WEB  The most widely used part of the Internet is the World Wide Web (often abbreviated “WWW” or called “the Web”. The World Wide Web is a system of interlinked hypertext documents accessed via the Internet. 6
  7. 7. HYPERTEXT  Hypertext is a method of instant cross- referencing. In most Web sites, certain words or phrases appear in text of a different color than the rest; often this text is also underlined. When you select one of these words or phrases, you will be transferred to a page that is relevant to this word or phrase. Sometimes there are buttons, images or portions of images that are “clickable”. 7
  8. 8. ACCESSING THE INTERNET  You can access the Internet at home with a personal computer or at various community locations, like the library, schools, etc. Be aware that if you use a public computer to access the Internet, there is probably an Internet Use Policy and you will be responsible for following those rules and policies.  NOTE: To see the Roanoke Public Library’s Internet Use Policy go to then click Policies tab then Acceptable Use. 8
  9. 9. REQUIRED TO GO ON INTERNET  If you are using your own computer, you will need to have at least 3 pieces of hardware / software to access the internet. 9
  10. 10. #1 A MODEM  A modem is the piece of hardware that “calls” your Internet Service Provider (ISP) and connects your computer to theirs. A modem can connect through a phone line or through a cable connection. 10
  11. 11. #2 INTERNET SERVICE PROVIDER  Your computer cannot connect directly to the Internet. You need a third party, the ISP, to connect to the Internet. The ISP you chose will provide you with the necessary software to connect your computer to theirs, and then to the Internet. Some Internet providers are free while others charge a monthly fee. Differences in ISPs include:  Connection speed  Appearance of online ads  Number of hours included in their plan each month  Number of email accounts provided  Web page space available 11
  12. 12. #3 WEB BROWSER  This is the software that allows you to view graphics and other components on the Internet. The most popular are Microsoft Internet Explorer or Netscape Navigator. The appearance of a particular Web site may vary slightly depending on the browser you use. 12
  13. 13. ANTI-VIRUS SOFTWARE  Anti-virus software is a program that runs in the background of your computer and continually scans your hard drive for viruses. If a virus is detected, the program notifies you and quarantines the infected file so you can safely delete it from your computer.  You want to make sure you have an antivirus program installed AND up to date on your computer! Some viruses can be spread just by opening a website and there is no way to know until it has infected your computer! 13
  14. 14. FIREWALLS  Firewalls are programs that add another level of security and are especially important to have if you connect through a cable modem or another connection that is “on” all the time. A firewall protects your computer from someone on the outside gaining access. Without a firewall, someone could potentially access the files on your computer, or send emails through your email account. 14
  15. 15. COOKIES  A cookie is information that a website puts on your hard disk so that it can remember something about you at a later time. Cookies are required for many websites to display correctly or accumulate information you are entering.  If it is a reputable website, it is usually safe to accept cookies. 15
  16. 16. URL  Every website on the Internet has a unique address and to access that website, you must know the address. A website address is called a URL, or Uniform Resource Locator. 16
  17. 17. ADDRESS OF A WEBSITE  The format of website addresses are almost all the same. Most start with www, for world wide web. Then comes the actual address of the site, followed by a “dot” extension, which identifies the domain. The address is like a house number-it identifies a specific person or account. 17
  18. 18. DOMAIN  A domain is a group of hosts (or computers that have web sites on them) that are of a same or similar organization. The domain is like a street address—a lot of people live or have accounts there. There are 6 common domains set up for US Internet sites: 1. .com Commercial 2. .net Network 3. .gov Government 4. .edu Educational 5. .org Organization (usually not for profit) 6. .mil Military 18
  19. 19. EXAMPLE  An example of a website address is:   “uncanmanuals” is the address.  .com is the domain extension  NOTE: Since every website address must be unique, the same name may be used for different websites but they will each use a different dot extension. 19
  20. 20. TEN POPULAR WEBSITES  You have probably heard of or will hear of these websites, even if you never use them. 1. Google (—a site where you can set up an e-mail account, read the news, get directions, and go shopping, but at its core Google is a search engine. 2. Wikipedia (—an online encyclopedia that is free but it is user-written and edited. 3. Amazon (—it began as a way to sell books without costs associated with a physical bookstore and has become a store for almost everything 20
  21. 21. MORE OF WEBSITES 4. Facebook (—a social networking website for keeping in touch with old friends and making new ones. 5. eBay (—an online auction where people sell everything, from real (DVDs, cars, furniture) to more conceptual (one man auctioned his life). 6. Yahoo (—a search engine, an e-mail outlet, and a news source. 7. The Drudge Report (—Matt Drudge combines links to other new sources and stories he writes himself to bring his readers the latest news and rumors. It broke the Monica Lewinsky story in 1998. 21
  22. 22. MORE WEBSITES 8. Blogger (—creates a website for people to blog. Blog is an abbreviation of “web log”, a term for an online journal, column, etc. 9. Craigslist (—low-tech, local version of eBay. It is like a huge community bulletin board, allowing a person to find just about anything. 10. YouTube (—allows users to post short videos. 22
  23. 23. FINDING A WEBSITE  There is no “directory” available for internet addresses (websites) because there are so many and they change all the time. However, as we will explore later, there are lots of Search Engines you can use to find sites about the information you are seeking. 23

  38. 38. SEARCH ENGINES  On the Internet, a search engine is a coordinated set of programs that includes: 1. A spider (also called a “crawler” or a “bot”) that goes to every page or representative pages on every Web site that wants to be searchable and reads it. 2. A program that creates a huge index (sometimes called a “catalog”) from the pages that have been read. 3. A program that receives your search request, compares it to the entries in the index, and returns results to you. 38
  39. 39. SEARCH ENGINE APPROACHES  Major search engines such as Google and Yahoo (which uses Google) index the content of a large portion of the Web and provide results.  Ask Jeeves provides a general search of the Web but allows you to enter a search request in natural language such as “What’s the weather in Seattle today?”  Special tools and some major Web sites such as Yahoo let you use a number of search engines at the same time and compile results for you in a single list. 39
  40. 40. INDIVIDUAL WEBSITES  Individual Web sites, especially larger corporate sites, may use a search engine to index and retrieve the content of just their own site. Some of the major search engine companies license or sell their search engines for use on individual sites. 40
  41. 41. HOW TO SEARCH  If you know of a specialized search engine such as SearchNetworking that matches your subject (for example, Networking), you’ll save time by using that search engine.  If there isn’t a specialized search engine, try Google or perhaps other search engines for their results. 41
