A feature introducied to the Windows operating system with Windows 95, allowing users to share files and printers among machines. Today, file and print sharing means that Internet users can share or swap files online—including digital files having songs or photographs. Vancouver-based Ludicorp Ltd.’s photo-sharing and social-networking service Flickr is a Web service or Web application that assists in photo sharing. The nice feature about Flickr is that no special software has to be installed on a home computer, and it works for the Mac, Windows, and Linux. All the user needs is a Web browser. So when a digital photograph is uploaded to Flickr, it becomes part of a network that connects digital photos in a database by subject or relation to the user. Photos can be organized in many ways and shared easily with others. Furthermore, Flickr can receive digitalized photographs from a camera-featured telephone and then post the photos directly to a Weblog, or blog. The positive feature of this capability is that individuals can chat with each other online and exchange digitalized photos at the same time. The file-sharing leader KaZaA announced in 2003 that it would extend its services by offering free telephone calls through the Internet, employing the same techniques that made the KaZaA music-sharing service hugely successful. Another file-sharing leader was Napster, Inc., which was shut down in 2001 because users contravened the Digital Millennium Copyright Act. It was reopened as a commercial file-sharing in 2004.
