	Introduction to Mosaic
		An Internet-based global hypermedia browser that allows you to find, retrieve and display documents and data from all over the Internet
		Part of the World Wide Web (WWW) project, started by CERN to provide a distributed hypermedia environment
		Mosaic software is available for displaying data in different formats, including audio and video formats, on workstations and PC's, and is available free from NCSA in Illinois
	Client / Server Model
		 
	Mosaic Clients and Servers
		 
	Hypermedia Browsing
		Based on hypertext documents which may have links to other documents, pictures, audio or video
		Document sections can be browsed in order provided by links - non-linear, non-hierarchical
		Links can be underlined text or parts of a picture. Click with a mouse button to follow the link and open that document
		Mosaic provides the multimedia displays by activating display software on your workstation, for example, xv to display pictures
		Can access other servers WAIS, gopher, ftp

	Hypertext documents
		HTML - HyperText Markup Language
		simple formatting capabilities: boldface headers, bulleted lists, italic addresses
		links are provided through anchors, which give the file name as a URL
		Uniform Resource Locator (URL) identifies the host, the format of the information, and a protocol to use when retrieving the information.		Example: (not real): 	http://www.npac.syr.edu/public/homepage.html
		You can put pictures in-lined if they are in GIFF format
