The first they used for this generation is because the technology,to build the computer systems, and programming language.

They want to solve the math problems in 17^th century

The machines from the mechanical era,

Mechanical gears, dials. Are capable of leading to riots in Frances by workers fearful of losing their jobs.

The abacus emerged 5000 years ago

It's is considered the first computer, helps the used to make computations using a system of sliding beads arrange on a rack. It had less importance when paper and pencil emerged.

Significant advance computing devices

Blase pascal (1642) .- Invented the Pascalina; numerical wheel calculator

Josheph Marie Jacquard (1801) created a machine called the jacuard loom used punched cards in the textile industry to control the patter of the textiles being waved.

Revolutionary machines

1823 .- Charles babage created the difference engine

The analythical machine (1833)

After babagge couldn't finish the difference engine and incorporate an arithmetic logic unit, control flow in the form of conditional branching and loops and integrated memory.

Ada Lovelace was the world's first programmer (1833)

she was the Charles Babagge's asisstant. Wrote programs for the analytical engine using punched cards.

Herman Hollerith.

He created the punched card tabulating (1890) it was very succesful nad hollerith went on to form the company that became IBM.

Pioneers in computing
