Robert Dennard

Inventor of RAM

United States of America

Robert Dennard invented one of the most significant advances in computer technology: dynamic random access memory, best known as "RAM."

Robert Dennard was Born in Terrell, Texas; on Sep 5 1932 he received BS (1954) and MS (1956) degrees in Electrical Engineering from Southern Methodist University. In 1958 he received a Ph.D. in Electrical Engineering from Carnegie Institute of Technology and joined IBM's Research Division.

In 1966, Dennard invented one-transistor Dynamic Random Access Memory (or DRAM, better known simply as RAM).At that time, he was at IBM's Thomas J. Watson Research Center, where he has worked on field-effect transistors, integrated circuit design, and memory cells and organizations.

Dennard received the patent for one-transistor DRAM in 1968.

Before his invention, computers were too large and heavy to be installed in private homes or desk tops. In fact, they required separate storage space and air conditioning to cool them.This invention of one-transistor Dynamic Random Access Memory (DRAM) allowed major increases in computer memory density and decreases in cost.

Ray Tomlinson

Hai dear friends…

Wishing you all a very prosperous new year 2008…

Hotmail, Rediffmail, Yahoo, Gmail … and the list is endless. With various features and sizes all these e-mail providers are conncting several minds who like to write their expressions in long or short notes in a cost effective way.I am sure you are also a frequest user of e-mails. Do you know the man behind this idea…

He is Ray Tomlinson... Sir, We express our heartfelt thanks.

Ray Tomlinson

Inventor of e-mail.

Ray Tomlinson graduated in electrical engineering in the MIT and entered to work in the company BBN in 1967, shortly before which its company received the order to work for ARPANET

In 1971, Ray Tomlinson was assigned to a project called SNDMSG. This program was not new, in fact it had existed for a number of years. By today's standards it was more than primitive. All it did was allow users on the same machine to send messages to each other. Users could create text files which would then be delivered to mailboxes on the same machine.

Ray was assigned to make this simple application do a little bit more. As it turned out, he had been working on something called CYPNET, which was intended to transfer files between computers within the ARPANET. So he modified CYPNET to perform one additional task - to append to a file. This was pretty simple and the change was quickly made.

After that, Ray made a decision which changed history. He created the format of the email address. He defined it as a mailbox name, the @ sign, and the machine's node name. He used the @ sign because "it seemed to make sense. I used the @ sign to indicate that the user was 'at' some other host rather than being local." The first email message was unceremoniously sent between two PDP-10 nodes of the ARPANET network. The contents of the first email message is lost to history, but it was probably something like "QWERTYUIOP".

Tomlinson has changed the world and made a lot of others rich without cashing in himself.Email has changed the way business -- from huge corporations to mom-and- pop shops -- does business. It's altering the way millions shop and bank.

pls put your queries and comments..
All wishes for 2008

Augusta Ada

Augusta Ada King.

Amazing Fact:First computer programmer.

Country:England.

Ada Lovelace was best known as the first computer programmer. She was also known as Analyst, Metaphysician, and Founder of Scientific Computing.

August Ada Byron was born in London, England on December 10, 1815, the daughter of the illustrious poet, Lord Byron. Five weeks after Ada was born Lady Byron asked for a separation from Lord Byron. Ada never met her father (who died in Greece in 1823) and was raised by her mother, Lady Byron. One night, in November 1834, at a dinner party, Ada heard Babbage's ideas for a new calculating engine, the "Analytical Engine." In 1842, an Italian mathematician, Louis Menebrea, published a memoir in French on the subject of the Analytical Engine. Babbage enlisted Ada as translator for the memoir, and during a nine-month period in 1842-43, she worked feverishly on the article and a set of Notes she appended to it. These are the source of her enduring fame.

Published in 1843, Lady Lovelace's prescient comments included her predictions that such a machine might be used to compose complex music, to produce graphics, and would be used for both practical and scientific use. Her Notes anticipate future developments. Ada suggested to Babbage writing a plan for how the engine might calculate Bernoulli numbers. This plan is now regarded as the first "computer program."

A software language developed by the U.S. Department of Defense was named "Ada" in her honor in 1979.She died very young at the age of 37 of cancer in 1852 and was buried beside the father she never knew.

The Father of computers

Name:Charles Babbage

Amazing Fact:Inventor of The Difference Engine.

Country:England

Babbage is known for his ideas about building an "analytical engine", the predecessor of the digital computer. Although he never built his computer, his ideas influenced those who later carried out his ideas.

He is widely known as “The Father of computers”.

Charles Babbage was born in Teignmouth, Devonshire, England on December 26, 1792.the son of Benjamin Babbage, a London banker and Elizabeth teape. He attended Cambridge University. In the 1820's Babbage began developing his Difference Engine, a mechanical device that can perform simple mathematical calculations. Babbage was unable to complete it because of a lack of funding. During his working career he was a professor of mathematics at Cambridge university.In the 1830's Babbage began developing his Analytical Engine, which was designed to carry out more complicated calculations, but this device was never built.

Through out his life Babbage worked in many intellectual fields typical of his day and made contributions that would have assured his fame irrespective of the difference Engine and Analytical Engines.He died at his home in Dorset Street, London .on October 18, 1871.
