What are Digital Computers?

•A computer is a machine that manipulates data according to a set of instructions.

-Calculators, computer workstations, data-processing systems, microcomputers.

First Generation (1939-1954) - vacuum tube 1937 - John V. Atanasoff designed the first

digital electronic computer 1946 - Mauchly and Eckert start Electronic

Control Co., received grant from National Bureau of Standards to build a ENIAC-type computer with magnetic tape input/output, renamed UNIVAC in 1947 but run out of money, formed in Dec. 1947 the new company Eckert-Mauchly Computer Corporation (EMCC).

The Early Years of Digital Computers

  Throughout the early years, digital computers were big and was

very expensive. Nowadays, a digital computer processor can be held in the palm of your hand. Also, back in the days, digital computers can cost up to $500,000. Now, digital computers are less than 1000 dollars.

Digital computers in the 21st century

Current Digital Computer Technology

Japanese researchers are attempting to create a computer that requires no mouse or keypad

This computer will be run on human brain waves so everyone will be customized to the individual person

This technology will be very helpful for reasons such as; criminology, business, security, transportation, telecommunication, intelligence and espionage

The United Kingdom is also in the process of developing a computer that would be able to calculate 63 million times a second which is equals about 12000 desktops

The Future of Digital Computers

In conclusion, digital computers have made its way to modern technology throughout the years. This presentation is to acknowledge the power of today’s technology. Starting from being big as vacuum tubes funded by the air force down to hand held computers that could fit in anyone’s pocket. Having big companies such as Microsoft, Apple and automobile companies working on new inventions and projects, our future is looking brighter.
