APPLICATIONS OF EMBEDDED SYSTEMS

Introduction
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.

What is Embedded System?
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.

Advantages of Embedded System

• 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
Disadvantages of embedded system

• 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
