Hi! I love teaching and this is my personal repository of useful materials for those who study English. Enjoy!!!
I collect everything here that helps me move forward in learning the language. If it proves useful to someone else, Welcome!
Famous People in computer history
In 1822, Charles Babbage conceptualized and began developing the Difference Engine, considered to be the first automatic computing engine
that was capable of computing several sets of numbers and making hard copies of the results. Unfortunately, because of funding
he was never able to complete a full-scale functional version of this machine.
In June of 1991, the London Science Museum completed the Difference
Engine No 2 for the bicentennial year of Babbage's birth and later completed
the printing mechanism in 2000.
The Z1, originally created by Germany's Konrad Zuse in his parents' living room in 1936to 1938
and is considered to be the first electro-mechanical binary programmable (modern) computer and really the
first functional computer.
Atanasoff and Cliff Berry
Short for Atanasoff-Berry Computer, the ABC started being developed by ProfessorJohn Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the
Iowa State College (now Iowa State University). The ABC was an electrical
computer that used vacuum tubes for digital computation including binary math and Boolean logic and had no CPU.
J. Presper Eckret
The ENIAC was invented by J. Presper Eckertat the University of Pennsylvania and began
construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and
used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge
ruled that the ABC computer was the first digital computer, many still consider
the ENIAC to be the first digital computer because it was fully functional.
In 1975, Ed Roberts coined the term "personal computer"
when he introduced the Altair8800. Although the first personal computer is considered by
many to be the KENBAK-1, which
was first introduced for $750 in 1971. The computer relied on a series of
switches for inputting data and output data by turning on and off a series of
