HRM 3450 Tutorial 8 Notes – Commercial and Expanded
Introduction
• At that point the Internet became commercial and expanded rapidly into the form that
we know today.
• Although it is only marginally related to the major issues addressed, we would be remiss
if we did not complete this discussion with a mention of Sir Tim Berners-Lee, of CERN,
the European organization for nuclear research, who in 1991 developed the concepts
that became the World Wide Web and Max Andreessen of the University of Illinois,
who, in 1993, developed Mosaic, the first graphical Web browser.
• A brief review of the basics of computing.
• We began by recalling the input-process-output model for computing.
• Next we demonstrated the connection between that model and the components of the
computer system.
• We noted that implementation of the model requires four components: hardware,
software, communication, and data.
• The architecture of the computer system is made up of the hardware and system
software.
• In addition, a communication component exists to enable interconnecting systems.
• We discussed the general architecture of a computer and noted that the same
description applies to CPUs both modern and ancient, both large and small.
• We introduced the important concepts of virtualization, standards and protocols, noting
that these ideas will appear throughout
• There are many good general introductory computer texts available for review if you
feel you need one.
• New books appear so rapidly that we are reluctant to recommend any particular one.
• For alternative coverage of material you may find recent editions of various books by
Stallings [e.g., STAL05] or Tanenbaum [e.g., TANE07] to be useful.
