How were calculations computed in the past?
• Originally calculations were computed by humans, whose job title was computers. • These human computers were typically engaged in the calculation of a mathematical expression. • The calculations of this period were specialized and expensive, requiring years of training in mathematics.
Who invented the ENIAC computer?
Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer.
What is the history of computer image processing?
The world’s first scanned image was made on SEAC by engineer Russell Kirsch in 1957. The NBS also built the Standards Western Automatic Computer (SWAC) at the Institute for Numerical Analysis on the UCLA campus. Rather than testing components like the SEAC, the SWAC was built using already-developed technology.
Abacus The history of computer begins with the birth of abacus which is believed to be the first computer. It is said that Chinese invented Abacus around 4,000 years ago. It was a wooden rack which has metal rods with beads mounted on them.
What is the origin of the name Dhakal?
Dhakal ( Nepali: ढकाल) is a बाहुन surname found in Nepal. The Dhakals are believed to be the direct descendants of Rishi or sage Upamanyu, who is in turn believed to be descended from Rishi Vasishta. They are believed to have originated from a place called Dhapuk in the Achham District and Gorkha District of mid-western Nepal.
When was the first digital computer invented?
2700 B.C: The first digital computer, the Abacus is invented and used around the area of Mesopotamia. Yet, later iterations of the abacus appear in Egypt, Greece, and China, where they’re continually used for hundreds of years. The first abaci were likely used for addition and subtraction which must have been revolutionary for the time.
Which of the following is the Birta of Dhakal?
Yaku {Bhojpur and Gorkha} is known as the Birta of Dhakal; Syanja, Gorkha, Terathum, Bhojpur and Gorkha are famous places from which many Dhakals have emerged. Today, many Dhakals are also found in India and Nepal, especially in the Darjeeling district of West Bengal, Sikkim, Assam and in Bhutan.

What did Charles Babbage call the first computer?
His early 19th-century machines featured a way to input numbers, memory, and a processor, along with a way to output the results. Babbage called his initial attempt to build the world’s first computing machine the “difference engine.”
What were the achievements of the early era of computing?
During this early era of computing, there were a few notable achievements: The tide-predicting machine, invented by Scotch-Irish mathematician, physicist, and engineer Sir William Thomson in 1872, was considered the first modern analog computer. Four years later, his older brother, James Thomson,…
Who invented the first mechanical computer?
English mathematician Charles Babbage is credited with having assembled the first mechanical computers — at least technically speaking. His early 19th century machines featured a way to input numbers, memory, a processor and a way to output the results.
What is the name of the Victorian era computer?
Famed mathematician Charles Babbage designed a Victorian-era computer called the Analytical Engine. This is a portion of the mill with a printing mechanism.
Who is the father of modern computer?
In the early 1820s, it was designed by Charles Babbage who is known as “Father of Modern Computer”. It was a mechanical computer which could perform simple calculations. It was a steam driven calculating machine designed to solve tables of numbers like logarithm tables. This calculating machine was also developed by Charles Babbage in 1830.
What is the first generation of computer?

What was the first electronic computer ever made?
The first electronic computers were developed during the World War II, with the earliest of those being the Colossus. The Colossus was developed to decrypt secret German codes during the war. It used vacuum tubes and paper tape and could perform a number of Boolean (e.g. true/false, yes/no) logical operations.
What was the first computer in WW2?
Colossus—whose name was fitting for its size—was developed during World War II. The first electronic computers were developed during the World War II, with the earliest of those being the Colossus. The Colossus was developed to decrypt secret German codes during the war.
