Leader & Prerequisite Quotients

Dear readers,

Up to now we have discussed  four Quotients known as IQ,EQ,SQ,PQ.

Today i am going to discuss about their importance in leadership skills (Intelligence).

Obviously A leader  must

1. have Vision

2. Have Willingness to Reflection etc.

3. Proper Planning


In order to have great mission he needs to follow a best strategy or action paln (mission).


Inorder to explain Leadership Quotients i have considered a famous Ronthy's Leadership model in pictorial view.

All the best know  the prerequisite intelligence's (quotients) of leader from diagram and learn and practice well to become a great leader.

All the best.

Thank you

Five generations of Computers ...

Generations/ Evolution of Computers ...

Dear readers n friends Actually there are 5 types of generations of Computers. 

We can design Computers using different components from earlier days to current era.

Generation 1 - Computers using Vaccum tubes

Generation 2- Computers using Transistors

Generation 3 - Computers using IC (Integrated Circuits)

Generation 4 - Computers using Micro Processors

Generation 5 - Computers using AI (Artificial Intelligence) example: Super Computer 

Thank you all 

... In the next post I will discuss some more important things .

Yours Sri

µA741 information - LIC VIVA VOCE

µA741 is :

General-Purpose Operational Amplifiers

successful predecessor of the LM 101 IC

 it was made by fairchild company.

it is developed using the planar epitaxial process

The 741 IC is available in the market as 

• 8-pin metal can, 
• 10-pin flat pack, 
• 8 or 14 pin DIP

Tommorrow i will discuss other pins and curious things dear readers.

Identify the Inventor (ITI) series 3 - TRANSISTOR AND TRIODE inventors

Identify the Inventor (ITI) series 3 - TRANSISTOR AND TRIODE

Answer : Shockley and Lee De Forest

LEFT : Shockley (He is one of the three Transistor inventor)

RIGHT: Lee De Forest (Triode Inventor)

Dear Students and electronic enthusiast Please check the triode figure ? 

Already you know about Transistor Terminals Emitter, Base,Collector.

Please also know structure and Terminals of Vital Vaccum tube Triode ...

Identify the Inventor (ITI) series 3 - TRANSISTOR AND TRIODE

Identify the Inventor (ITI) series 3

 Clue : 

Identify the one of the inventors of transistor and inventor triode from left to right ?

Triode is the remarkable invention in electronics before transistor evolution.

Triode is used for amplification of signals on telephone lines in up to starting of 19th century.

GATE SERIES - RVSP SERIES 1

QUESTION : 

EXPLANATION: 

Know about Component (KC) - Transistor series

The answer for ITI SERIES Transistor inventor pic left to right are Bardeen,   Shockley,  Brattain.

Many of you know The term transistor is a contraction of the term trans resistance  but you don't know who told it?

Actually it was coined by John R. Pierce.

Do you know what is the name of transistor made by Bardeen, Brattain, and Shockley 

It is  point contact transistor ( in 1947).

May be i don't know how many of u seen it ? So i am posting its Diagram?

In the next post i will tell some interesting things and parts of point contact transistor ...

Thank you for your interest.

ITI (Identify the Inventor) Series 3 Transistor Inventors

Dear students and electronic enthusiasts and hobbyists

Today we will know little about the Transistor Inventors.

Today i will tell their names and their contribution in the transistor work?

You just name them from Left to right ?  

Because many people know their names but unable to distinguish between them. Hence i am poking this question ?

Shockley, Bardeen, and Brattain were jointly awarded the 1956 Nobel Prize in Physics "for their researches on semiconductors and their discovery of the transistor effect".

 John Bardeen was the thinker, a man who could look at an event no one else comprehended and go beyond common understanding to explain it.  Walter Brattain was the tinkerer, a builder who could put together any contraption asked. William Shockley was the visionary, a seer who predicted how important the transistor would be long before anyone else. 

There are a wide variety of semiconductor diodes like  

PN Junction Diode ((IN4007 -  (Small one), DR25 - (Large one) )

DR 25 Clearly exhibits reverse charcateristics.

Zener Diode (pink color one) shown in Left top pic.

In the right top pic older vaccum tube diode is shown. 

In left bottom pic diode symbol with terminals a(anode), k(cathode) is shown. 

In the last figure current direction along with polarities is shown . 

Please observe ALL.

Have you identified the scientist in the previous photo ...

He is also inventor of "Photophone "& "Metal detector"

He also extended his works to "Aeronautics" and "Eugenics" also.

Now at least you got some idea. 

I will give very simple clue his wife name is "Hello".

Dear students is none other than 

Alexander Graham Bell ...

He is the inventor of Telephone.

He given a big gift to his wife. He first talked to his wife named Hello with the telephone he invented. 

Hence first word that talked on telephone is Hello.

HENCE IT BECOME THE FIRST WISH ON TELEPHONE FOR EVERY BODY ...

ITS THE STORY BEHIND HELLO ...

ITS THE KNOWLEDGE WHICH CAN NOT APPEAR IN TEXT BOOKS ...

HOPE YOU GOT SOME THING FROM MY SIDE ... 

Thank you ...

 Next time i will discuss with some more good and curious things by making a tribute to graham bell. 

On his name we have bell laboratories.

          Salute Sir

HE ALWAYS SAYS

When one door closes another opens but we often look so long and so regretfully upon the closed door that we do not see the one which is open for us.

I was really inspired from this words from a decade  of years.

The meaning of this quotation in my view to all students is  : 

Students please see the opportunities which are opened don't think about already closed opportunities.

GO AHEAD …

ENTER INTO

YOUR DREAM UNIVERSITY

“WORK HARD UNTIL YOU FULLFILL YOUR DREAM”

Identify who is this famous scientist ?

Famous as : Father of Modern Telecommunications

There are a lot of good things to share about him. 

hence today i given 3 clues for finding him : quotation, photo, famous as.

If any body knows share the name. 

Later i discuss curious things about him. 

yours
