It is a convenient and efficient means of communication, education, as well as entertainment. The development of computer technology was a gradual process, and it dates back to more than 2, years ago. This was the abacus, an instrument that was used extensively in different ancient cultures for making fast arithmetic and astronomical calculations. Astronomical calculations eventually led the ancient Greeks and the medieval Muslim astronomers to invent the astronomical analog computers.
Punched cards Biography Herman Hollerith was an American inventor and entrepreneur whose inventions paved the way for the information processing industry in the late nineteenth and early twentieth century.

Herman Hollerith did undergraduate work at the School of Mines of Columbia University in New York. In he began work the U.S. Census Office, and soon was appointed a special agent charged with collecting statistics on the power and machinery used in manufactures.
His father, a Herman hollerith language teacher, died accidentally when Hollerith was just seven. His mother came from a family of skilled locksmiths in Europe who had set up a business of manufacturing horse-drawn carriages in America.
She brought him up with values emphasizing thrift, integrity, industriousness and self-reliance. Hollerith was academically brilliant. After graduating, Hollerith moved to Washington D. His job was to collect and analyze statistical information on the use of steam and water power by iron and steel industries.
But teaching did not interest him much and in his spare time he worked at the MIT lab facilities to solve the census problem. He tried to mechanize the census tabulation to save time and reduce errors.
He gained the knowledge of patent law by working as an assistant examiner in the U. Hollerith developed mechanical tabulators using punched cards to tabulate huge bodies of data very quickly.
These punched card tabulators built by Hollerith helped to compile the U. Census in only one year, whereas the previous Census had taken eight years. InHollerith founded the Tabulating Machine Company and started his own business. Hollerith died inin Washington D. A commemorative plaque was installed by IBM at his factory where the tabulating machines were manufactured.
They were used extensively throughout the twentieth century in the data processing industry, for data input, processing and storage. Early digital computers also used Hollerith cards.

Computer - History of computing: A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process.
In fact, calculation underlies many activities that are not .
