HRM 3450 Lecture 25 Notes – Standardized
Introduction
• New protocols and other standards are proposed and created and standardized as the
need arises.
• XML, RSS, and SIP are all examples of protocols developed recently to meet new
demands.
• Satellite telecasting, near-universal telephone communication, wireless
communications, and the Internet all demonstrate powerful and useful technologies
made possible by protocols and standards.
• Indeed, the Internet is a measure of the success to which protocols that govern
intercommunication between computer hardware and software have been standardized
throughout the world.
• Discussions of various protocols and standards will occur regularly throughout this book.
• The focus of this book is upon the architecture and organization of computers,
computer systems, and computer-based IT systems.
• Tehially, there is a slight differee i defiitio etwee the ters oputer
arhiteture ad oputer orgaizatio.
• We will usually not attempt to differentiate these terms and will use them
interchangeably.
• In this book we will be concerned with all four components of computer systems
• Hardware, software, data, and interconnectivity, and with the interactions between
each component.
• We will also look initially at the larger picture
• The organization of computer systems as components, themselves, to form enterprise IT
systems.
• First part is concerned with the system as a whole.
• The remainder is divided into four additional parts, consisting of discussions of number
systems and the representation of data in the computer, the hardware that makes up
