is one of the most important developments of the twentieth century

• The invention of the internet
• The discovery of penicillin
• The invention of Electronic Computer

• The development of the atomic bomb

Answer explanation

The computer and the information and communication technology built upon it have drastically changed business, culture, government and science, and have touched nearly every aspect of our lives. This text introduces the field of computing and details the fundamental concepts and practices used in the development of computer applications

A computer that performs calculations and logical operations with quantities represented as digits, usually in the binary number system of “0” and “1”.

• Digital computer
• Supercomputer
• Mainframe computer
• Analog computer

known as the first computer, it uses several rows of beads to represent numbers; each row stands for a place value and the arrangement of beads in a row stands for a digit

• abacus

• Commodore 64
• Apple I
• IBM 5100

Young French Mathematician - Invented one of the first gear based adding machines (Pascaline Calculator, Mechanical Calculator, Adding Machine) to help with enormous amount of calculations involved in the computing of taxes

• Albert Einstein

English Mathematician - Unveiled the first phase of his envisioned. Difference engine which also used ten-position gears to represent decimal digits. (Computer, Difference Engine, Analytical Engine)

• Ada Lovelace

• Blaise Pascal
• Charles Babbage

• Albert Einstein

One of the few people who understood the Analytical Engine’s enormous potential. - She described the similarity of Jacquard’s and Babbage’s inventions.

Answer explanation

designed and wrote out demonstrations of how complex mathematical computations could be constructed entirely from sequences of the basic set of arithmetic operations of which the Analytical Engine would be capable.

Required physically moving and interconnected parts. Such a device is almost certain to be slower, more prone to failure, and more difficult to manufacture than a device that has no moving parts.

• Mechanical Devices

• Electronic Devices

such as vacuum tubes of the sort used in early radios have, by definition, no moving part

• Mechanical Devices

• Electronic Devices
