The abacus - the firs computer?


The First Computing Hard

The First Programmer

Ada, the countess of Lovelac

Mother of computer prog (supposedly the first prog

A gifted mathematician.

She helped develop instru for computations on Babb Analytical Engine.

Saw Babbage's theoretic approach as workable.


The First Electrical compu

1890 Herman Hollerith

Able to count the census in 6 weeks rather t years

Used Jacquards punch cards Sorted into bins, count number of cards

Developed in 1800 by a French silk weaver

Electrical power

Tabulating Machine Company merged into IB


Aiken, Zuse, Atanasoff, Be

1936 - Harvard graduate student Howard Aiken began thinking of modern equivalent of analytical engine...

1939 Germany - Konrad Zuse completed first programmable, general-purpose calculating device to solve mathematical problems

Paper was in short supply during war, used film tape


1939 - Iowa St Professor Joh developed the electronic digit computer, the Berry Compute

The Mark I

1944 Harvard professor Howard Aiken completed Assistant Grace Hopper

Developed compiler for the computer

8 feet high, 55 feet long steel and glass used noisy electromechanical relays 5-6 times faster than a person

not very efficient

Enter data into computer using paper tape

Today in History

September 21st, 1976: The Cray-1, the first supercomput is delivered to Los Alamos Nationa Laboratory


History Summary

Knowing something about the evolu computers is helpful to understand why things are the way they are no

Computing devices have been aroun a long time

Digital computers are fairly new

Rate of improvement and growth is amazing
