Internet vs. World Wide Web

• The Internet is a worldwide computer network
  through which you can send a letter, chat to
  people electronically, or search for information
  on almost any subject of interest.  
• The World Wide Web is a collection of interlinked
  documents, graphics, and other multimedia that
  can be accessed using the Internet.

5
Web Browsers

• A Web browser is an application program that
  reads HTML documents/files to formulate Web
  pages. These Web pages make it easier to look at
  or find information on the World Wide Web.
• The two most common Web browsers are
• Microsoft Internet Explorer
• Netscape Navigator

6
Web Site Hosting

• Every Web site is hosted by a Web server (a
  computer that allows multiple people to access
  the same files at the same time). Maintaining a
  Web server can be costly therefore most
  people/companies who have their own Web site, and
  cannot afford the resources to maintain a Web
  server connected at high-speed to the internet,
  depend on an outside company to provide Web site
  hosting.

7
Web Site Hosting

• Still confused about Web site hosting?
• Try thinking of your telephone and the
  telephone company. You might have a telephone,
  but without a telephone company to provide you
  with the necessary services to use your
  telephone, your telephone is useless.
• Same with a Web site. You may have a Web site
  ready, but without Web site hosting to provide
  you with the necessary services, your Web site is
  useless.

8
Web Site Hosting

• e-Paluchs Web Site Hosting service allows
  parishes to have their Web site available on the
  World Wide Web without the parish having to
  inherit the cost of maintaining their own Web
  servers and high-speed connection.

9
High-Speed Internet Access

• As Web pages have grown more elaborate, the file
  size of the Web pages have increased. This is
  similar to the increased size of bulletin files
  because of the graphics now being used.
• Because of the file sizes, the speed at which
  modems can receive data has become important.
  Users want to see Web pages appear immediately on
  their screen, this requires high-speed services.

10
High-Speed Internet Access

• Businesses use T1 lines for Internet access
  because they are faster, but they are too
  expensive for homes and small businesses.
• Currently high-speed Internet access is offered
  three ways for the average user..

11
High-Speed Internet Access

• ISDN Stands for Integrated Services Digital
  Network. A fast Internet connection that allows
  you to talk on the phone and browse the Internet
  simultaneously while using the same line. It is
  also costly to the average user.
• Cable Modem Service High speed Internet service
  over existing cable networks. This service is not
  offered in all areas and the connection slows
  down when many users are on it.
• ADSL Stands for Asymmetric Digital Subscriber
  Line. A phone line that allows you to browse the
  Internet and use your phone at the same time.
  Also allows for rapid transmission of data from
  the Internet. ADSL is also becoming the standard
  for home and small business use.

12
URLs

Search Engine Types of Searches

• There are two types of searches

• Main
• Advanced

22
Search Engine Main Search

• With Main Search, you can either type words in
  the search box or use plus and minus signs to
  make your search more accurate.
• A plus sign () in front of a word means that
  word must be in the Web pages for them to be a
  match. For example,
• vacations cruise bahamas can be used to look
  up vacation cruises to the Bahamas.
• A minus sign (-) in front of a word means that
  any page that has that word is excluded from the
  list of matches. For example, vacations -cruise
  bahamas can be used to look up vacations to the
  Bahamas but not cruises.

23
Search Engine Advanced Search

  logic to form your queries, so you can control
  the order of the results. These techniques are
  simple to use through keywords such as

• AND
• OR
• AND NOT
• NEAR
• ( )
