A web browser is software that allows users to view websites. Common browsers include Internet Explorer, Firefox, and Safari. Websites with HTTPS URLs or lock icons in the address bar are generally secure. To find a website's domain, look at the creator name or suffix at the end of the URL like .com, .org, or .edu. The easywhois website provides information about a site's author, creation date, and owning organization. FTP transfers entire files while HTTP transfers parts of files to view web pages. Basic online safety rules include avoiding all caps, bullying, meeting strangers, and sharing private information.
