In the future you will be able to instantly access websites. You will have a cyber-assistant to scour the Net, delivering data right to your digital doorstep. At least that's the promise. But most of us are still a long way from that reality. Yet there are ways to minimize the frustration of going online. After all, life is much too short to spend precious time waiting for web pages to download, or hunting for information on dozens of sites. In the interest of making Web surfing a more satisfying experience, we offer ten tips:
    1View sites in text-only mode by turning off the graphics.
    Sure, web designers spend a great amount of time creating wonderful graphics, but it can take quite a while to download large graphic files. To speed things up, turn off the images in your web browser.
    With Internet Explorer 5.0, under the Tools menu, select Internet Options, then click the Advanced tab. Now uncheck Show Pictures.
    Thoughtful designers will include something called an ALT tag, which is a written description of the image. If you want to see a particular image, click on the tag with your right mouse button and select View Image. For Mac users, just hold down the mouse button over the graphic. You can also click the Image button in Navigator to load all the images.
    2Use the Stop button.
    When you access a website, what you are actually doing is downloading a set of digital files. You can see how the download is progressing if you look at the status bar located in the lower left hand corner of your web browser. If you get tired of waiting, click the Stop button to view the files that have already been downloaded. Then you can decide if you want to continue. If you do, click the Reload or Refresh button.
    3Increase your cache.
    Files you download are stored in a cache (pronounced like "cash") on your hard drive. That way when you return to a site, you don't have to download the files again, just access them from your cache. After a while though, the cache becomes full. Your web browser automatically deletes old files as you continue to surf the Web. But if you visit many of the same sites regularly, you can speed up access by caching more of them. To do this, increase the size of your cache. 10 Mb is optimal.
    If you use Netscape Navigator 4.0, under the Edit menu, choose Preferences, then click on Advanced. Now click on Cache. In the appropriate box, increase the cache size.
    With Explorer 5.0, under the Tools menu, select Internet Options. Next, on the General tab, click on Settings. Use the slider to increase the cache
    4Save keystrokes by using Bookmarks or Favorites.
    Web addresses or URLs can be unwieldy. Worse, if you type it wrong, you will get an error message. To avoid these problems, save the addresses of sites you want to revisit. For details on how to do this, read the Bookmarks article.
    5Use the Find feature of your web browser.
    Once you've downloaded a document, the Find button can quickly locate a particular term in which you are interested. Why take the time to scroll through the entire document?
    6Pick two search engines and learn how they work.
    The difficulty of finding specific information is by far the biggest complaint we hear. Although dozens of search engines are available, pick two, then take the time to learn them well. For more on searches read Searching the Web. In case you're interested, our favorites are Yahoo! and AltaVista.
    7Choose your own home page.
    Both Netscape and Microsoft set their websites as the default home page when you launch your web browser. But if you like to begin your surfing by reading a daily newspaper or better yet, Learn the Net, why not start there first? Here's how to select a new home page.
    8Open a new window.
    While you are downloading one web page, you can actually access another site by opening a second browser window. With Navigator, go to the File menu and choose New Web Browser. With Explorer, select New Window from the File menu. A word of caution: Although you can open multiple windows, this will slow down your computer, so don't go overboard. Also, remember to close the additional windows to free up disk space.
    9Surf during off-peak hours.
    Most commuters experience rush hour, when highways bog down with traffic. The same phenomenon happens on the Internet, usually in the late afternoon and early evening, when people log on to check e-mail, chat and play games. If you want to avoid the slowdown, go online in the morning or late at night, when traffic is lighter.
    10Get a faster connection.
    If you are still using a 28.8 Kbps modem, it's time to upgrade. Most people these
    days access the Web at twice that speed. New modems offer access at 56 Kbps (kilobits per second). Before you upgrade, however, make sure your Internet service provider supports 56 Kbps modems.
    For the impatient, the good news is that many companies are investing large sums of money to solve the problem of slow Internet access. Exotic technologies such as Asynchronous Transfer Mode (ATM) , Digital Subscriber Line (DSL) and cable modems promise enormous bandwidth. Will it ever be enough? Who knows? Until then, happy surfing.
