This presentation discusses the importance of electronic device knowledge in computer science education. It begins with an introduction to electronic devices such as transistors and diodes, which are used to control electrical currents for information processing and system control. It then explains how semiconductors like silicon are used in modern electronic devices due to their ability to conduct electricity under certain conditions. The rest of the presentation discusses the history of semiconductors and transistors, how semiconductor devices work, their use in computers for calculations and data storage, and their crucial role in modern digital technologies and data systems, concluding that the modern age would not be possible without semiconductor electronic devices.

4. Introduction:
Electronic device and circuit 4
Electronic devices are components for controlling the flow of
electrical currents for the purpose of information processing
and system control. Prominent examples include transistors
and diodes. Electronic devices are usually small and can be
grouped together into packages called integrated circuits.

Why
electronic
device?
• Now a days all of the modern electronic
devices like laptops, tablets, PCs , smart
phones are made up with semiconductors.
That is electronic device. They use
semiconductors because:
• An insulator substances do not conduct
electricity verywell.
• An conductors substances that electricity
readily.
• But a semiconductor is a man made material
that can be made to conduct electricity at
sometimes and conductother times.
• Semiconductors are used to create discrete
electronic circuit elements , like transistors ,
diode and to simulate resistances,
inductances and capacitance also integrated
circuitchips.

6. How works electronic
devices ?
The heart of modern electronic devices are semiconductors and these
semiconductors are two types:
1. Pure or intrinsic semiconductor:
Example: Silicon, Germanium
2. Impure or extrinsic semiconductor:
There are two types : p –type and n- type semiconductor.
Both p and n –type semiconductors are made with doping on the pure
semiconductors. As pure semiconductors conductivity is not up to the
mark. Weuse doping method pure semiconductors to increase
conductivity

referred to as an
extrinsic semiconductor. Doping is also used to control the
color in some pigments.

8. History of semiconductors :
The story starts with named william
shockley.He was a brilliant academic from
eqully roots. His father was a mining engineer
fluent in eight languages, and his mother was a
highly successful Standford graduate. The three
scientists were jointly awarded the 1956 Nobel
Prize in Physics for "their researches on
semiconductors and their discovery of the
transistor effect".

9. Semiconductor/electronic
device in computer science:
 The importance of those semiconductor/electronic device is huge
in computer science education and we will discuss some of these
here:
1.These devices are made with silicon that heart of all personal
computer
2.Semiconductors allow electricity to be used to perform just about
all of the useful functions we see in everyday life.
3. A large number of these semiconductor switches (called
transistors) canbe built on tinny pieces of silicon and used
perform calculations. Even in supercomputer also use of
semiconductor
4. In computer signaling LED which is made with diode.
5. Digital signaling system totally dependent on semiconductor.
6. Each and every system as like as motherboard, CPU also
semiconductors device
7.Even in memory card to flash drive using semiconductors devices
forsaving data

10. Semiconductor/electronic
device in computer science:
Electronic device and circuit
1.Big data center is using semiconductor systems.
2.Cloud computing is totally based on data center.
3.Techgiants like google, facebook are making millions of
data. To save those information they are using harddrives
on the computer systems which are totally based on
semiconductors technologies

11. Value:
 There are lot of demand of semiconductors onthe
electronic industries
 There has been created lot of semiconductors
companies in the world. Some of theseprominent
company :Intel, samsung, Texus, Tosihba

Without semiconductors in 20th century is like impossible
things. Because now simple calculator, wrist watch, tablet PCs
each and every digital devices are built with semiconductors
technologies.
Whole data base systems are now rely on semiconductors
directly or indirectly.
Even the digital lighting systems to surrounding all the
following semiconductors technologies.
So that this modern age would be impossible without
semiconductors that means without electronic device
knowledge in the computer science education the modern era
would be impossible.
