'Grace Hopper’s Biography: A Great Pioneer in Data Processing\r'

'It was 1906 in New York urban center when the great pioneer in information processing, decorate Murray Hopper, was born to the parents Walter Fletcher Murray and Mary Campbell motor horn Murray. Even as a two-year-old child grace loved skill ab surface mathematics and the new technological advances that were coming out, somely because of her surrounding milieu — her mother was a mathematician. Although at the metre women were not considered as principal(prenominal) to gild as men were, she would turn out to be one of the most important influences of the century.\r\nIn 1924 Grace attended Vassar College, majoring in the sciences, specifically mathematics and physics. After quaternary years of unvoiced behave she receive with Phi Beta Kappa honors and a Vassar College Fellowship. With that she progressed to earning her MA in mathematics at Yale University in 1930, and her Ph.D. in 1934, along with two Sterling Scholarships and an election to Sigma Xi. While fi nishing her college education she marry the New York University English teacher Vincent Hopper. Her estimator technology life would soon cast down following her graduation.\r\nUpon graduating, Grace was accepted to the power of Ordinance at Harvard University. That is when she was introduced to and assigned to spurt on simoleons I — the offshoot large-scale U.S. computer and precursor of electronic computers. Her first gear assignment with Mark I was to â€Å"have the coefficients for the interpolation of the arc tangents sinless [in about one week]”… not a problem for Grace.\r\nShe would then be the three person ever to course the Mark I. At that same clock, the Mark I was being utilise to calculate the angles at which naval guns were to be aimed. Shortly after(prenominal) that a machine called BINAC was being certain which used the C-10 language. The C-10 according to Grace, â€Å"has been the basis for most graves since. ‘A was add, â₠¬ËœM was multiply, ‘B was bring, ‘C was clear; it was a beautiful code.” Grace was then forced to teach herself octal arithmetic, since that is what the code was performed in. A sort time after that, many people started to bank a user-friendlier computer was needed. Grace got to work on it.\r\nGrace was credited with the first compiler in 1952, the A-0. The compiler was â€Å"a set of instructions that translated mathematical code into machine language.” Later on she produced the A-1 and the A-2, which were basically upgrades of the previous compiler. Her 1957 FLOW-MATIC compiler (or B-0) which was used mainly for business programs, was the first to translate English into the machine language. A later program in 1959-61 (COBOL) was based on her FLOW-MATIC and was used in the UNIVAC — the first commercial electronic computer.\r\nGrace Hopper was a hard working woman who â€Å"worked to attract pains and business interests to computers and to bridge the gulf betwixt management and programmers.” After serving in the Navy from 1943 †1986, during which she received the rank of advert admiral, she retired to take her final job as the senior consultant with Digital Equipment Association. Grace Hopper, the great pioneer in data processing and computer technology, died in 1992 at the age of 86.\r\n'
