Chapter 9. Exploring the Internet

<feature><title>What You’ll Do</title> </feature>

Introduction

The Internet is a global collection of more than a billion computers (and growing) linked together to share information. The Internet’s physical structure includes telephone lines, cables, satellites, and other telecommunications media. Using the Internet, computer users can share many types of information, including text, graphics, sounds, videos, and computer programs. The World Wide Web (also known as the Web or www) is a part of the Internet that consists of Web sites located on different computers around the world.

History of the Internet and the World Wide Web

The Internet has its roots in the Advanced Research Projects Agency Network (ARPANET), which the United States Department of Defense started in 1969. In 1986, the National Science Foundation formed NSFNET, which replaced ARPANET. NSFNET expanded the foundation of the U.S. portion of the Internet with high-speed, long-distance data lines. In 1991, the U.S. Congress expanded the capacity and speed of the Internet further and opened it to commercial use. The Internet is now accessible in almost every country in the world. The World Wide Web was developed in Switzerland in 1991 to make finding documents on the Internet easier. Software programs designed to access the Web, known as Web browsers, use point-and-click interfaces. The first such Web browser, Mosaic, was introduced at the University of Illinois in 1993. Since the release of Mosaic, Microsoft Internet Explorer, Netscape, and AOL have become some of the most popular Web browsers.

Connecting to the Internet

Universities and large companies are most likely connected to the Internet via high-speed wiring that transmits data very quickly. Home computer owners usually rely on a modem and the phone lines already in place. In some areas, however, several faster connection options are becoming available and affordable. There are DSL (Digital Subscriber Lines), wires that provide a complete digital connection; cable modems, which use cable television lines; and wireless, which doesn’t use wires or phone lines. DSL and cable modems, also known as broadband connections, are continually turned on and connected to an Ethernet network so you don’t need to establish a connection using a dial-up modem. Data travels more slowly over phone wires than over digital lines and cable modems. Wireless provides a mobile connection to the Internet using an AirPort connection anywhere there is a wireless base station, such as a router or a network hub. Whether you use a phone line, a DSL line, a cable modem, or a wireless device, Mac OS X can help you establish a connection to the Internet.

Before you start the process to set up an Internet connection, you need to select an ISP (Internet Service Provider), which is a company that sets up an Internet account for you and provides Internet access. ISPs maintain servers connected directly to the Internet 24 hours a day. You pay a fee, sometimes by the hour, but more often a flat monthly rate. To connect to the Internet, you need to obtain an Internet account and connection information from your ISP or your system administrator. Each type of Internet connection requires certain connection information, including:

  • ISP Phone Number. A number to create a dial-up connection.

  • Account Name. A user name for the Internet account.

  • Password. A security password for the Internet account.

If your ISP needs it, you may also need the following information:

  • IP Address. An IP (Internet Protocol) address is a unique identifier of your computer on the Internet.

  • Subnet Mask. A filter that helps your computer differentiate between computers on a local network and the Internet.

  • Router. A device address that sends and receives information over the Internet.

  • Domain Name Server (DNS). A computer that translates a Web site name into an IP address.

  • Proxy. A computer your Macintosh uses to access the Internet.

When you have the connection information from your ISP or network administrator, you can use the Network pane in System Preferences to set up, configure, and display status for all your network connections, such as Modem, Ethernet, and AirPort.

Getting Internet Connection Assistance

At the bottom of the Network pane is the Assist Me button. When you click the Assist Me button, it starts the Network Setup Assistant, which asks you a series of questions to help you set up your Internet Connection.

Getting Internet Connection Assistance

Creating Multiple Connections

If you have a mobile computer, such as a MacBook, you can set up multiple connections for different locations. Setting up multiple connections allows you to connect to the Internet at home using a dial-up connection, at the office using an ethernet connection, or on the road using a wireless connection.

If you have a dial-up modem or AirPort card, you can use the Internet Connect application located in the Applications folder to help you quickly create an Internet connection to different configurations in your current location.

Protecting your Computer from the Internet

When you connect to the Internet, you can access Web sites and information on the Internet, but other users on the Internet can also access information on your computer. You can prevent this by activating a firewall, another security layer of protection. A firewall is a security system that creates a protective barrier between your computer or network and others on the Internet. The firewall monitors all communication between your computer and the Internet and prevents unsolicited inbound traffic from the Internet from entering your private computer. The firewall discards all unsolicited communication from reaching your computer unless you specifically allow it to come through. If your computer is directly connected to the Internet, you should activate a firewall. If you are sharing an Internet connection on your network to provide Internet access on multiple computers, you should activate the firewall on the computer connected to the Internet only to avoid creating network communication problems. For more information and instructions on setting up a firewall, see “Configuring an Internet Firewall,” on page 409 in Chapter 16.

Sharing an Internet Connection

If you have an Internet connection and work on a network, you can share the Internet connection with other computers on your local area network. For more information and instructions on sharing an Internet connection, see “Sharing an Internet Connection,” on page 408 in Chapter 16.

Setting Up a Modem Connection

If you have a dial-up modem installed on your computer, you can set up and use a modem connection to access the Internet or another computer. You only need to set up a dial-up connection once. After you set up the dial-up connection, you can use the Show Modem Status menu to easily connect and disconnect from the Internet or network, and show modem connection information. When you are connected, the Finder displays a connection icon and connects information in the menu.

Set Up a Modem Connection

  1. Click the System Preferences icon in the Dock, and then click the Network icon.

  2. Click Modem in the list.

    • If a modem is not in the list, click the Add (+) button, click Modem from the Interface pop-up, and then click Create.

  3. Click Advanced.

  4. Click the PPP tab, and then specify your user name, password, and ISP phone number.

    • Specify PPP Options to redial a busy connection, automatically connect when starting TCP/IP applications, and automatically disconnect if you select Log Out from the Apple menu.

    Set Up a Modem Connection
  5. Click the TCP/IP and DNS tabs, and then specify any settings provided by your ISP, such as IP Address, Subnet Mask, Router, and DNS Servers.

  7. Click the Modem tab, and then specify any settings specific to your computer’s modem.

  8. Click OK.

  9. Click Apply.

Setting Up an Ethernet Connection

If you have a DSL or cable modem, you can set up and use an ethernet connection to access the Internet. In addition to connecting to the Internet, you also use ethernet to connect to a local area network (LAN). When you set up an ethernet connection using a cable modem or on a corporate network, some settings are typically configured automatically by a BOOTP (boot protocol) or DHCP (Dynamic Host Configuration Protocol). If your network supports ones of these services, you can use the Configure IPv4 pop-up in the TCP/IP area to select a protocol. If your ISP uses PPPoE (Point to Point Protocol over Ethernet), you need to specify your account and password. Check with your ISP or network administrator to determine if this applies to you.

Set Up an Ethernet Connection

  1. Click the System Preferences icon in the Dock, and then click the Network icon.

  2. Click Ethernet in the list.

    Set Up an Ethernet Connection
  3. If you want assistance, click Assist Me, and then follow the instructions.

  4. Click Advanced, if needed.

  5. Click the TCP/IP and DNS tabs, and then specify any settings provided by your ISP, such as IP Address, Subnet Mask, Router, and DNS Servers.

    Set Up an Ethernet Connection

    Trouble?

    If your Internet connection is having problems, click Renew DHCP Lease to refresh your IP address.

  6. Click the AppleTalk tab, and then specify settings to be part of a local AppleTalk network.

  7. Click the Proxies tab, and then specify any settings provided by your ISP.

  8. Click the Ethernet tab, and then select a configuration (automatic or manual) and specify settings.

  9. Click OK.

  10. Click Apply.

Setting Up an AirPort Wireless Connection

If you have an AirPort card on your computer and are within range of a wireless base station, such as a router or network hub, you can set up and use an AirPort connection to access the Internet. AirPort is Apple’s 802.11b-based wireless networking device that enables you to connect to the Internet without using network wires or phone lines. Setting up an AirPort connection is similar to setting up an ethernet connection. AirPort networks are identified by a network name. You can join a specific network or select one of the detected AirPort networks.

Set Up an AirPort Wireless Connection

  1. Click the System Preferences icon in the Dock, and then click the Network icon.

  2. Click AirPort in the list.

    Set Up an AirPort Wireless Connection
  3. Click Turn AirPort On, if needed.

  4. Click the Network Name pop-up, and then select a wireless network. If requested, enter a password.

  10. Click the Proxies tab, and then specify any settings provided by your ISP.

  11. Click OK.

  12. Click Apply.

Setting Up Multiple Connections

If you have a mobile computer, such as a PowerBook or iBook, you can set up multiple connections. For example, you can use a laptop to access the Internet at home using a dial-up modem, go to work and connect to a network using ethernet, or relax at a coffee shop and browse the Web using AirPort. Each set of network connections is called a network port configuration. You can create different port configurations with unique priorities for different locations, which makes switching from one location to another easier. You can quickly access different locations using the Location submenu on the Apple menu.

Set Network Port Configurations and Locations

  1. Click the System Preferences icon in the Dock, and then click the Network icon.

  2. Click the Location pop-up, and then select one of the following options:

    • Automatic. Default location.

    • A location name. Switches to the location name.

    • New Location. Creates a new location, such as “home”.

    • Edit Location. Changes settings for a location.

    Edit Location.
  3. Select the network you want to disable or enable, click the Action button, and then click Make Service Inactive or Make Service Action.

  4. Click Apply.

Making an Internet Connection

After you set up your connection in the Network Preferences pane, you can also use the pane to connect to the Internet. This is not always convenient, so Mac OS X provides status menus on the right side of the menu bar. The status menus makes it easy to quickly log into different configurations in your current location for dial-up modem, PPPoE for ethernet, Bluetooth, and AirPort connections. You can use the Network Preferences pane to enable the menus.

Understanding Web Sites and Browsers

A Web site contains Web pages linked together to make searching for information on the Internet easier. Web pages are documents that contain highlighted words, phrases, and graphics, called hyperlinks (or simply links) that open other Web pages when you click them. Some Web pages contain frames. A frame is a separate window within a Web page that lets you see more than one Web page at a time. Web browsers are software programs that you use to “surf the Web,” or access and display Web pages. Browsers make the Web easy to navigate by providing a graphical, point-and-click environment. Safari is a browser from Apple that is built into Mac OS X Leopard. Microsoft Internet Explorer and Netscape Navigator are other popular browsers. With a Web browser, you can display Web pages from all over the world, use links to move from one Web page to another, play audio and video clips, search the Web for information, bookmark Web pages for easy access, and print text and graphics on Web pages.

Understanding Web Sites and Browsers

Starting and Customizing Safari

Safari is a Web browser that you use to search the World Wide Web. You can start the Safari application using the Safari button in the Dock or the Safari icon in the Applications folder. After you start Safari, you might need to enter a user name and password when you use a dial-up modem to establish a connection to the Internet. After you establish a connection to the Internet, you are ready to explore Web pages on the Internet. The elements of the Safari window allow you to view, print, and search for information on the Internet. You can customize the Safari window display to conform to the way you work. The View menu allows you to turn on and off different display elements.

Start the Safari Application and Customize the Window

  1. Display the Dock on the desktop, and then click the Safari icon.

    Start the Safari Application and Customize the Window
  2. If necessary, click Connect to dial your ISP. You might need to type your user name and password before Safari connects to the Internet.

Browsing the Web

A Web address (also known as a URL) is a unique place on the Internet where you can locate a Web page. With Safari, you can browse sites on the Web with ease by entering a Web address or by clicking a link on a Web page to access a new site. When you type a Web address in the Address bar, Safari tries to find a recently visited page that matches what you’ve typed so far. If Safari finds a match, it fills in the rest of the address. As Safari opens the Web page, the Address box shows a blue-shaded progress bar as the page loads. The first page you open in a window or a page you specifically mark is the SnapBack page. Each window has only one SnapBack page. Safari remembers this page so you can quickly return to it after opening other Web pages. As you browse the Web, Safari stores information about Web sites you visit and information you’ve entered, which other user can view. You can prevent this by using Private Browsing (New!), which clears the history list, Downloads window, AutoFill information, searches, and cookies are deleted. It’s as if you never used Safari.

Open and View a Web Page

Use any of the following methods to display a Web page:

  1. In the Address box, type the Web address, and then press Return.

    If you have recently entered the Web page address, Safari remembers it and tries to complete the address for you. The suggested match is highlighted. Click the correct address in a list of possibilities or continue to type until the address you want appears in the Address list.

  2. Click any link on the Web page, such as a picture or colored, underlined text. The mouse pointer changes to a hand when it is over a link.

  3. Browse Privately (New!). Click the Safari menu, click Private Browsing, and then click OK. To skip the confirmation, Option-click the Private Browsing command.

    1. To turn it off, click the Safari menu, and then click Private Browsing.

  2. Click the History menu, and then click Mark Page For SnapBack.

  3. Click a link to another Web page.

    Important

    If you type an address in the Address box, select a bookmark or select a Web page from the History menu, the Web page is marked as the SnapBack page.

  4. Click the SnapBack button (an orange circle) in the Address box.

Important

If you perform a Google search or click the SnapBack button in the Google search box, Safari removes the SnapBack button from the Address box.

Browsing the Web Using Tabs

When you open a Web page, it opens in the same window you are using. If you want to view more than one page at a time in a single window, you can open Web pages in separate tabs (New!) or new windows. You can also bookmark a set of tabs (New!) for easy access in the future or revert to the tabs that were open the last time you used Safari. Before you start opening Web pages in tabs, you can set tab browsing options to specify the way you want to use tabs in Safari. When you open a page in a tab, the Tab bar appears (below the Bookmarks bar) with the name of the Web page along with a box you can use to close the tab. You can also use the View menu to show the Tab bar. If you select a Web page from the History or Bookmarks menu, the page opens in the current tab. When you use the Back and Forward buttons in the Address bar, Safari displays Web pages previously viewed in the current tab.

Navigating Basics

As you browse the Web, you may want to retrace your steps and return to a Web page you’ve recently visited. You can move backward or forward one location at a time to show sites you’ve previously visited in this session. After you start to load a Web page, you can stop if the page opens too slowly or if you decide not to access it. If a Web page loads incorrectly or you want to update the information it contains, you can reload, or refresh the page. If you get lost on the Web, you can start over with a single click of the Home button.

Move Back or Forward

  • To move back or forward one Web page at a time, click the Back button or the Forward button on the Address bar.

Bookmarking a Web Page

Rather than memorizing URLs or keeping a handwritten list of Web pages you want to visit, you can use the Bookmarks Library to store and organize the addresses. When you display a Web page or a set of tabs (New!) that you want to display again at a later time, you can add the Web page or tab set to your Bookmarks Library. After you add the bookmark to the Bookmarks Library, you can quickly return to it by using the Bookmarks bar or Bookmarks menu to select it. If you have bookmarks in other browsers, such as Internet Explorer, Netscape Navigator, and Mozilla, you can import the bookmarks in the Bookmarks Library using the Import Bookmarks command on the File menu.

Filling Out Forms on the Web

Safari can use information in your Address Book or data you previously entered in an online form to automatically complete online forms you need to fill out in the future. AutoFill is a service that helps you complete online forms and log in to Web sites with a user name and password. You use the AutoFill pane of the Safari preferences to select, modify, or delete which information AutoFill uses to complete a form or log in. When you use AutoFill to automatically fill in information, Safari highlights the data in yellow so you can see the changes. If you no longer need the AutoFill service, you can keep Safari from automatically completing forms and log ins. If you run out of room in a text field, you can now resize text fields on any Web page by dragging the corner of the field to make more room and reflow the Web page (New!).

You can find all kinds of information on the Web. The best way to find information is to use a search engine. A search engine is a program you access through a Web site and use to search through a collection of Internet information to find what you want. Safari comes with the Google search engine built-in to the program. When performing a search, the search engine compares keywords with words that it finds on various Internet Web sites. Keywords are words or phrases that best describe the information you want to retrieve. If the search engine finds your keywords in the stored database, it lists links to the matched sites. When you open a link from the results, you can use the SnapBack button to quickly return to your search results. In addition, you can search within a Web page to display the found count and highlight matching terms within a page (New!).

  1. Click the Google Search box, type a word or phrase you want to find, and then press Return.

Printing a Web Page

Web pages are designed for viewing on a computer screen, but you can also print all or part of one. Before you print, you should preview the page to verify that it looks the way you want. When you are ready to print, Safari provides many options for printing Web pages. If the Web page consists of frames, you can print the specific frame you want to print. You can also use the Print dialog to create a PDF of a Web page or send a Web page as a PDF fax or PDF mail attachment.

Saving a Web Page
