The document provides an introduction to embedded systems including: 1) An embedded system is a microprocessor-based system incorporated into a device to monitor and control its components. Embedded systems perform predefined tasks with specific requirements. 2) Some of the earliest embedded systems include the Apollo Guidance Computer and the Autonetics D-17 guidance computer. 3) The document discusses the components of an embedded system including microcontrollers, resistors, capacitors and transistors. It provides examples of embedded systems like washing machines, camcorders and ATMs.

3. Introduction of embedded system
• An embedded system is a microprocessor-based
system that is incorporated into a device to
monitor and control the functions of the
components of the device.
• An embedded system is a special-purpose system
in which the computer is completely encapsulated
by the device it controls.
• an embedded system performs pre-defined tasks,
usually with very specific requirements.

4. History
• One of the first recognizably modern embedded
systems was the Apollo Guidance Computer,
developed by Charles Stark Draper at the MIT
Instrumentation Laboratory.
• An early mass-produced embedded system was
the Autonetics D-17 guidance computer for
the Minuteman missile, released in 1961.

11. Microcontroller
• A microcontroller is a small computer on a single
integrated circuit containing a processor
core,memory,and programmable input /output
peripherals.
• Microcontroller are designed for embedded
applications in contrast to the microprocessor used in
personal computer or other general purpose
applications.
