7. Why Microcontroller…?
 The choice of
microcontroller or
microprocessor is critical
to the performance,
efficiency, and capabilities
of the embedded system.
It determines factors such
as processing speed,
memory capacity,
communication
interfaces, and power
consumption.

8. Printed Circuit Board
 PCB stands for “Printed
Circuit Board.” It is a
fundamental component in
many electronic devices,
including embedded
systems. A PCB is a flat
board made of non-
conductive material
(typically fiberglass or
composite) that holds
electronic components and
provides pathways for
electrical connections.

9. Brain Of An Embedded System
 The microcontroller or
microprocessor
determines the
capabilities and
limitations of the
embedded system. It
affects factors such as
processing speed,
memory capacity,
communication
interfaces, power
consumption, and more.

11. Conclusion:
Embedded systems are the unsung heroes behind
the devices we use daily. They combine hardware
and software to perform specific tasks efficiently,
from controlling household appliances to running
critical medical equipment. These systems play a
crucial role in various industries, adapting to new
technologies and driving innovation. As
technology advances, embedded systems
continue to shape the way we interact with our
environment and the devices that make our lives
easier.
