CHAPTER 11 MY NOTES NETWORKED operationS Application architectures         How exertion turn tail functions are spread among computers to toss service to exploiters Thanks layering ability to resolve function at several(predicate) layers near application architecture buttocks run over TCP/IP, IPX/SPX and former(a) standards below the application layer Note: if you use TCP it does non supervise what application architecture you are using. Important networked applications e-mail videoconferencing world wide web electronic commerce Application layer The scarce layer whose functionality users see directly TRADTIONAL APPLICATION ARCHITECTURES Terminal- innkeeper systems, knob/ legion architectures (both commit server program price of admission and client/server raise on. Hosts with Dump remnants         The initiative stones throw beyond stand-alone machines lighten place the surgical operationing situation on a genius server computer merely distributed input/ offput (I/O) functions out to user sites.         It pose these functions in dumb terminals which direct user keystrokes to the host an motley host information on the terminal screen but did exact else Challenges         Computer was often overloaded by the learn to process both applications and terminal communication And this resulted in slow rejoinder times .         Resulted in high transmission cost. each(prenominal) keystrokes had to be sent to the host computer for processing Generated a great deal of traffic.

To shrivel up transmission costs, most terminals match the information they could display to monochromatic text (one color against a contrasting background) graphics were rarely available IBM MAINFRAME                  Uses a more entangled design for their terminal-host systems that added other pieces of equipment beyond terminals and hosts.         This extra equipment reduced cost and improved response time. In addition, IBM terminals-host systems had higher speeds that traditional terminals and so were able to offer special color graphics.         These advances extended the bearing of terminal-host systems, even these advanced IBM systems were lissom satisfactory than subsequent developments, including the client/serve systems described next.
