3. What Is Electronics?
• Electronics is the study of how to control the flow of
electrons.
• It deals with circuits made up of components that
control the flow of electricity

4. Electronic Components
• An electronic component is any basic discrete device or
physical entity in an electronic system used to affect
electrons or their associated fields.
• Electronic components are mostly industrial products.
• Components can be classified as active, passoive or
electromechanic.

5. Active Components
• Those devices or components which required external
source to their operation is called Active Components.
• Active Components produce energy in the form of
voltage or current.
• Examples − Diodes, Transistors, Transformers, etc.

6. Diode
• Diode, is an electronic component that allows the flow of current in only
one direction.
• blocking it when passing the opposite direction.

7. Zener Diode
• A Zener diode is a type of diode that allows current to flow in the
conventional manner - from its anode to its cathode i.e. when the anode is
positive with respect to the cathode.When the voltage across the terminals
is reversed and the potential reaches the Zener voltage (or "knee"), the
junction will breakdown and current will flow in the reverse direction.

8. Photodiode
• A photodiode is a type of photo detector capable of converting light into
either current or voltage,
• Used in solar cells

9. LED (Light Emitting Diode)
• A device that produces light.

10. Transistor
• A transistor is a semiconductor device used to amplify and switch
electronic signals and electrical power.

11. Passive Components
• Those devices or components which do not required
external source to their operation is called Passive
Components.
• For Example: Resistor, Capacitor, Inductor etc…

12. Resistor
• A resistor is an electrical component that limits or regulates the flow of
electrical current in an electronic circuit. Resistors can also be used to
provide a specific voltage for an active device such as a transistor.

14. Inductor
• An inductor, also called a coil, choke, or reactor, is a passive two-
terminal electrical component that stores energy in a magnetic
field when electric current flows through it. An inductor typically consists
of an insulated wire wound into a coil around a core.

15. Capacitor
• A capacitor is a passive electronic component that stores energy in the
form of an electrostatic field.

16. Transformer
• A transformer is a static device which transfers electrical energy from
one circuit to another through the process of electromagnetic induction. It
is most commonly used to increase (‘step up’) or decrease (‘step down’)
voltage levels between circuits.

17. Introduction Of Embedded System
• An embedded system is a combination of computer hardware and
software, either fixed in capability programmable, designed for a specific
function or functions within a larger system.
• An embedded system is a special-purpose computer system designed to
perform certain dedicated functions. It is usually embedded as part of a
complete device including hardware and mechanical parts.

18. Significance Of Embedded System
• Due to their compact size, low cost and simple design aspects made
embedded systems very popular and encroached into human lives and
have become indispensable. They are found everywhere from kitchen
ware to space craft. To emphasize this idea here are some illustrations.

19. Hardware Architecture Of Embedded
System

20. Features Of Embedded System
• Embedded systems have very limited resources, particularly the memory.
Generally, they do not have secondary storage devices such as the
CDROM or the floppy disk.
• Embedded systems are constrained for power, As many embedded
systems operate through a battery, the power consumption has to be very
low.
• Embedded systems need to be highly reliable.
• Some embedded systems have to operate in extreme environmental
conditions such as very high temperatures and humidity.

21. 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
