In 1993 the first graphical Web browser software was designed at the University of Illinois at Champagne-Urban. Graphical Web browsers allow a Web page designer to combine text, graphics, sound, and video together on a Web page. The graphical Web browser is the software that brought the Internet to the attention of the average person. The two major Web browsers produced today are Netscape Navigator and Microsoft Internet Explorer. Protocols Protocols are software that manage and transport data across computer networks.
Internet protocols transfer the data from the server computer to the client computer and vice versa.
Protocols transfer the data by breaking it down into small units called packets. A packet is similar to an envelope in that it wraps the data and contains the destination and return addresses of the computers that are communicating to each other. The protocol also tells the computers what type of data is contained in the packet. The World Wide Web was created in 1991 in Switzerland and is a sub-network of the Internet. People interact with the World Wide Web through software known as a Web browser.
