Topics

What is electronics? -Use of electricity for measurement , control , communications , computing and similar applications. Use of electronics in daily life -Alarms , lights , calculators , televisions , computers , telephones , fridges ,microwave ovens , etc.

Introduction

Introduction

Thomas Alva Edison’s invention of bulb.

Valve technology- -developed by Sir J A Fleming -triode valve developed by Lee de Forest -further development led to introduction of radio , television and early form of computer

Radio waves – -Waves of electromagnetic energy that travel at the speed of light. -Prediction-James Clerk Maxwell.

First demonstration-Heinrich Hertz. Radar- Radio Detection and Ranging -Involves transmission and reflection of radio waves. Transistors It is an electronic component used to control electric current and to provide amplification

Important subjects of Electronics

Integrated Circuits Small chips of material incorporating the

functions of several separate components of a conventional electrical circuit

Microprocessor Integrated circuit that contains all the

functions of a computer’s central processing unit .

Batteries-source of electrical energy

Important subjects of Electronics

Origin of Electronics

Time conservation Work made easy Heavy jobs reduced Storage of information Access to information when needed Telecommunication

Benefits

Processing time Machine based working Very less features Bulky gadgets Require pre-knowledge about gadgets

Drawbacks

Development of integrated circuits Wide applications of microprocessors digital watches , hand –held computers and

electronic gaming. Development in digitalization of audio

signals- measuring amplitude of signal at short intervals.

Medical Electronics-progressed from computerized axial tomography and the use of C-scanners

Development in Electronics

VLSI Circuits (Very Large Scale Integrated)

Broadband Communication Systems

Typewriters-replaced by Computers which are

networked-can communicate with one another

Old fashioned roll of stamps replaced-automatic

electronic mailing machines

Developments in computer systems-introduction of

tablet-mini size handy computer

Developments in Electronics

Advantages Printing made easy Several copies of

documents Photostat machines Hand held tape

recorders Computer writing-

more effective-tools for spelling and grammar

Internet-connects all over the world

www-Huge resource of information

Mobile devices with technological advancements

Benefits of tracking system , digital maps

Technology in education

Disadvantages

Careless usage-irrepairable problems

Threat to confidential information

Manufacturing materials-plastics-non bio-degradable

Process of manufacturing-pollutes environment

Vote by e-mail Robotic Dragonfly DARPA Pix-net Camera Heat Sink

Upcoming Technology

30 futuristic phones Controlling TV by hand An call from plant Flying cars Self driving cars

Upcoming Technology

Sharing televised pictures , conversations , graphics , circuits and interactive software.

People-auditory impairment-communicate easily.

Some jobs-conducted from home. Acquiring a job-easy-official proceedings-

forwarded from home.

Advantages of Electronics

Advantages of Electronics Storage of communicated messages and

important information. Economically viable Speed Electronic journals- -easily searchable -interactive -accessible -links

Security issues-hackers. Computers-affected by viruses. Difficulties-processing bulky data-providing

feedback. Duplication of electronic data. Problems-’e-mail privacy’. Cyber addiction

The Dark Shadow of Electronics

Electronic gadgets-part of our daily life. Overcome many difficulties-make tasks

easy. Advantages as well as disadvantages

associated with electronics. Precautions must be taken while using

technological equipments. New technologies-which can overcome present disadvantages
