Internet Service Providers
To connect to the Internet, users pay a fee to a company or organization that lets users connect to the Internet by dialing into its computers using a modem. Service Providers provide the dial-up telephone number, an e-mail address, and some technical assistance.
The Internet Browser
Browsers are software that allow you to see the contents of the World Wide Web. Internet Explorer, Netscape Communicator or Navigator, or Mosaic are called graphical World Wide Web (WWW) “browsers” or “clients”.
The Cache Memory
The cache memory of the Internet browser saves Web pages, along with the images, sounds, text and whatever else may be contained on those pages, to a temporary directory on your hard drive. These files are used to decrease the time it takes for a Web page to load up. This is accomplished by having your Internet browser read the files off your hard drive, rather than reloading the same data off the Web site's server, which is usually far slower. Both Internet Explorer and Netscape Navigator have this feature.
It is recommended that you clear your cache memory frequently. Clearing the cache will save you hard drive space as well as allow faster access to Web pages that are placed into this area. It is also advisable when exiting a Web based E-mail service, you clear your cache to prohibit others from having any unjust access to your private messages.
To clear your cache memory for Internet Explorer follow these instructions:
Under the "Tools" menu, select "Internet Options...", and the following window to the left should appear. Now click the "Delete Files..." button. The small dialogue box below should popup. Select the option to "Delete all off-line content", and click "OK". Your browser will now delete on and off-line stored pages.
When clicked, this option opens a side bar to the left of your browsing area (the space in which you view Web pages). A list of previously viewed Web sites appear, arranged by date with the most recent beginning at the top. Double click the Web site you wish to return to.
You can clear your history by clicking on Internet options in the "Tools" menu. Click on the "Clear History" button.
