This module serves as an introduction to the Internet and accessing the information there using Web browsing and electronic mail (email) software.
The Internet is a global network formed by connecting millions of computers. The World Wide Web is a way of accessing the information that's available via the Internet.
A Uniform Resource Locator (URL) is the address that points your Web browser to a specific Web site or page.
Check your Web browser for the small lock icon at the bottom of the screen before sharing personal or credit information with a Web site. The icon means the site is secured and verified by a third-party vendor.
A virus is a destructive file that replicates itself. Protect yourself from infestation in the following ways:
Don't open email attachments from strangers or if you're not expecting the file.
Install virus-scanning protection software.
Don't use diskettes from an unknown source. Even then, you're taking a risk because trusted and known sources might not know they're infected!
A firewall is hardware or software that prevents unauthorized access to a lone system or a complex network.
