NCSA Mosaic for Microsoft Windows User's Guide

A Brief History and an Overview

In late 1992 and early 1993, NCSA staff members were looking for a way to make the information on the Internet more accessible to the average computer user. The search for tools that would lend themselves to the sort of graphical, point-and-click interface that has proven so effective over the past decade led eventually to the World Wide Web and HTML.

The World Wide Web is a large-scale networked hypertext information system initially developed at CERN, the European Laboratory for Particle Physics in Geneva, Switzerland, in 1989. The Web was designed for hypermedia information distribution and to take advantage of developing standards for hypertext markup, hypermedia distribution, and information locators:

HTML
HyperText Markup Language, an SGML-based markup language that includes provisions for rich-text formatting, hyperlinks, inline graphics, and external viewers (for data formats that cannot be handled internally by the viewer software)
HTTP
HyperText Transfer Protocol, a fast, lightweight transfer protocol designed for the interactive, networked hypermedia environment
URL
Uniform Resource Locator, a uniform reference system for locating individual files on virtually any computer system on the Internet

The first release of NCSA Mosaic, in April 1993, was a client for X Window System platforms. Clients for the Macintosh and Microsoft Windows platforms followed in the fall of 1993. As of April 1994, the following versions had been released:

NCSA Mosaic for Microsoft Windows
Version 2.0alpha4
NCSA Mosaic for the Macintosh
Version 1.0.3
NCSA Mosaic for the X Window System
Version 2.4
