2006 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design", Raj Kamal, Publs.: McGraw-Hill, Inc. 2 “An Embedded System is a computer based system for an application(s) or product with dedicated software embedded in it. It may be an independent system or part of large system. – Present Book Definitions:

2006 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design", Raj Kamal, Publs.: McGraw-Hill, Inc. 3 “It is any device that includes a programmable computer but is not itself intended to be a general purpose computer.” – Wayne Wolf, Ref: 79

2006 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design", Raj Kamal, Publs.: McGraw-Hill, Inc. 4 “Embedded Systems are the electronic systems that contain a microprocessor or a microcontroller, but we do not think of them as computers- the computer is hidden or embedded in the system.” – Todd D. Morton, Ref: 77
