Cyberspace and the World Cyberspace and the World
Wide Web DefinedWide Web Defined The term cyberspace was coined by
science fiction author William Gibson. We now use this term to describe a variety of computer related applications, such as, communication, interaction, information retrieval, and visualization. Cyberspace may be described as the “universe” of all on-line exchanges. For example, classes can be taught over the Internet, professors and students can read texts and Journal articles on-line, and various professionals can perform data searches to facilitate their theoretical and/or applied work.

W3 -- World W3 -- World Wide Web Wide Web
The Web may be described as a software application that functions within cyberspace and utilizes Internet hardware and inter-connectivity protocols as its vehicle of on-line communications and data transfer.
The Internet serves as a major common network that connects numerous on-line services that maintain “access ramps” or gateways and other access protocols to the “Information Super Highway.”

W3 W3 Protocols Protocols
The Internet is comprised of a large number of independent, interconnected networks. By the late 1960s and early 1970s, a fairly robust on-line communications system was put into place by ARPA. Trough a set of TCP/IP data was broken into chunks, then sent over different routes and then reassembled at its point of destination. IPNG or IP version “x” is designed to solve the rapidly shrinking space of Internet host addresses.

W3 W3 Protocols Protocols
Through the utilization of several sets of rules (protocols) Web browsers can communicate with various servers on the Internet. Following is a list of some of the most popular protocols:
HTTP: The Web’s built-in (native) protocol for the transmission of hypertext documents.
FTP: Enables the transmission of text or binary files between computer hosts across networks
Gopher: Information sharing system that utilizes menus, documents, or connections to Telnet sessions.
NNTP: Protocol used for Usenet news distribution.
Telnet: Protocol for remote logon to a computer
host. 9
WWW Addresses WWW Addresses and Domain Namesand Domain Names
In order to facilitate its use, specific IP numeric addresses were assigned an alphanumeric host name through the Net’s DNS. Following is a selected list of high-level domain names:
Domain Name Type of Host.com Commercial organization
.edu Educational Institution
.gov Typically U.S. government
.mil U.S. military
.net NAP (e.g., pacbell.net)
.org non-profit organization
