An embedded system combines mechanical, electrical, and chemical components along with a computer, hidden inside, to perform a single dedicated purpose.

2. An embedded system combines
mechanical, electrical, and chemical
components along with a computer,
hidden inside, to perform a single
dedicated purpose. There are more
computers on this planet than there are
people, and most of these computers
are single-chip microcontrollers that
are the brains of an embedded system.

3. An embedded system is a dedicated computer
system designed for one or two specific functions.
This system is embedded as a part of a complete
device system that includes hardware, such as
electrical and mechanical components.

9.  Small size and faster to load
 More specific to one task
 Easy to manage
 Low cost
 Spend less resources
 These operating system is dedicated to one
device so performance is good and use less
resources like memory and micro-processors

10. Difficult to upgrade
If any problem occurs then you need to reset
settings
Nearly not scalable
Hardware is limited
Troubleshooting is difficult
Difficult to transfer data from one system to
other
