"Who invented the computer and what year?" The answer to the first part of the question is Charles Babbage. Interestingly, the implementation of the design of what should have been the first computer was actually completed in 1989. But, if the question is "Who invented the computer first and electronically?" then it is John Presper Eckert & John W. Mauchly. They built the ENIAC (Electronic Numerical Integrator and Computer). Then why is Charles Babbage given the credit of inventing the computer? Charles Babbage was the first person to introduce the idea of "programmable machines". Charles Babbage hardly imagined that his distaste for human errors would one day result in inventions such as desktop computers and laptop computers.
To reach today's era of Artificial Intelligence, natural language processing and high power processing, computer inventions had to go through various generations. This all started with Charles Babbage's difference engine in 1822. The difference engines and analytical engines (if completed) would be heavily mechanical. Their weight would be in tons (although analytical and difference engine are not considered to be of any generation, let us consider them to be of zeroth generation for the sake of reference). The main feature of first generation (1940 - 1956) computers was vacuum tubes. The architecture of second generation (1956 - 1963) computers was based on transistors. Third generation computers (1964 - 1971) saw the introduction of integrated circuits. And fourth generation (1971 - present) computers are based on microprocessors. And now we are in the fifth generation (present - henceforth) of computers, where artificial intelligence takes precedence. Following is the story of the man who invented the computer, and when he did that, little did the world know that Charles Babbage had managed to alter the course of history .
Early Years
Charles' father, Benjamin Babbage, was a businessman. Therefore, money wasn't a hindrance for young Charles' education. Young Charles went to many schools and was home tutored before he went to Helmond Academy in Baker street. This is where his romance with mathematics began. Later he went to Cambridge for further studies. He was subsequently transferred to Peterhouse Cambridge where he studied analytical philosophy and computer science. However, he never really graduated with honors. Charles Babbage was later conferred with an honorary degree in mathematics.
Since Charles Babbage was a profound mathematician, he soon started researching on various mathematical subjects. While doing so, he had to encounter a lot of logarithmic calculations. The only way to perform these calculations was through the use of logarithmic tables. Since there were no mechanical calculators in those times, the use of logarithmic tables became very tedious and erroneous. This experience was very hampering to the study of mathematics. Also, the accurate results would take forever to be calculated, hence, Charles decided to design a machine, which not only would save time but (more importantly) be accurate as well.
Design of Charles' Computer
In the early nineteenth century, mathematical tables were calculated by 'computers'. These were people who were assigned the task of computing, and hence were called computers. Due to this, there was a high rate of errors. Having studied computer science and being an acclaimed mathematician, it was obvious to him that he should build a calculating machine. Babbage started working on the design of an engine which would analyze input and give appropriate output.
Since his design was meant to eliminate differential errors involving mathematical tables, it was called 'difference engine'. Difference engine was to calculate the finite differences, and thereby avoid the need for multiplication and division. But unfortunately, due to the huge size and the complexity of the design, Charles Babbage couldn't complete it. But this did not deter him from designing difference engine 2, which was an improved version of the original difference engine.
After his failure to implement his designs of difference engine, Charles Babbage came to the conclusion that his engine designs needed improvement. He then started to design engines that were better in analysis than their predecessors. The successive designs were more efficient and complex than the previous ones. These complex machines were called analytical engines. Due to continuous work in the design, any one machine couldn't be called an analytical engine. His final design of the analytical engine was implemented only in 1989, which is far more accurate than today's electronic calculator.
1943 ENIAC (Electronic Numerical Integrator and Computer), the first general-purpose electronic digital calculator begins to be constructed. This computer by most is considered to be the first electronic computer.
Electric? or Electronic?
It is the human being shared invention
Yes, Babbage invented the first fully automatic programmable digital computer. However his machine was entirely mechanical and he was never able to get supporters or funding to build it. It took another century before the automatic programmable digital computer was reinvented, but this time it was electronic. The inventor Tommy Flowers, built 11 of them during WW2 between 1944 and 1945 for Bletchley Park to use for breaking the German "tunny" teletype cypher, but these machines were kept classified by the British until the late 1970s so are usually not in the history books. The people that most history books credit for the invention of the modern automatic programmable digital electronic computer worked on ENIAC but it is not known who in this group got the idea first, only that the idea came in early 1945.
Legally in the US he is considered the inventor of the first electronic digital computer. It was not programmable, it was designed specifically to solve linear simultaneous equations of up to 29 variables.
One of the persons who made a telling contribution to the history of computer is John Vincent Atanasoff. Atanasoff invented and spearheaded the development of the Atanasoffâ??Berry computer between 1939-1942. The ABC was the world's first automatic electronic digital computer.
The first electronic and digital computer is the Mark 1 Machine (also known as "Automatic Sequence Controlled Calculator").

An electric or a digital portfolio is a collection of someone's work that can be viewed on a digital device such as a computer or tablet. One might create a digital portfolio for a job interview.

invantor of digital thermometer
Well yes there is. it is sort of like an computer clock. it is also digital clock . and people say it as a electric clock.
