8 Computers Are Your Future Chapter 14 © 2006 Prentice-Hall, IncSlide 8 Centralized vs. Distributed Structures  Centralized structures are managed by a central IT department  Each network entity contains the same software and configuration settings

9 Computers Are Your Future Chapter 14 © 2006 Prentice-Hall, IncSlide 9 Centralized vs. Distributed Structures  Distributed structures enable each user to customize their technology tools  Each network entity contains its own software and configuration settings

10 Computers Are Your Future Chapter 14 © 2006 Prentice-Hall, IncSlide 10 A type of computing in which different components and objects comprising an application can be located on different computers connected to a network. So, for example, a word processing application might consist of an editor component on one computer, a spell-checker object on a second computer, and a thesaurus on a third computer. In some distributed computing systems, each of the three computers could even be running a different operating system.computingcomponents objectsapplicationnetworkapplicationoperating system One of the requirements of distributed computing is a set of standards that specify how objects communicate with one another. There are currently two chief distributed computing standards: CORBA and DCOM.distributed computingCORBADCOM
