- Designed by Howard Akien(1900-1973), a Harvard engineer in 1937.
- Mark-1 was the first automatic electromechinal computer.
- Maek-1 was 51 ft. tall and 3 ft. wide having 18000 vaccum tubes.
- Mark-1 used instruction stored in papper tapes and punch cards.
- Mark-1 consist of 7 lakhs 50 thousend parts.
- Jon Von Neumann was the doctorate in mathematics from the University of Budapest on set theory.
- Jon Von Neumanndesigned the EDVAC with team of J.P Eckert and J.W. Mauchly.
- Jon Von Neumannintroduced the concept of having a stored programe in memory in 1945.
- This concept led to the beginning of the first generation of the computers.
- An English Mathematician (daughter of English Poet Lord Byron) carried forward yhr work ofCharles Babbage.
- Lady Augusta Add Lovelace developed programes for performing mathematical calculation on the Analytical Engine.
- Lady Augusta Add Lovelace was first computer programmer.
- One programming language 'Ada' was named after her.
- A professor of mathematics developed a machine called Difference Engine in 1822.
- In 1833, he developed the Analytical Engine.
- He is known as the Father of the modern computer as his invention Analytical Engine hadthe work for more of the characteristics of modern computers.
- Developed by Ana American Dr. Hermam Hollerith(1869-1926) in 1887.
- Hollerith Tabulator Used punched cards for input, output and instructions.
- This machine was used by American Department of Census.
- In 1886, he founded the tabulating machine company which was renamed as IBM(International Business Machine) later.
- Developed by Charles Babbage in 1833.
- Analytical Engine had store for storing data and introduction result.
- Analytical Engine had an output device to produce printed result.
- Analytical Engine had a unit for calculation 'mill'.
- All the modern computers are based on analytical engine
- Design by Charles Babbage(1792-1871) an English mathmatematician, in 1822.
- Difference Engine could solve equations.
- This project could not be completed due to lack of funds.
- Difference Engine is housed in the Science Museum, London and all is till in perfect working order.
