A computer or a computer scientist is a person who pursues a profession in the study, design, production, management and maintenance of information processing systems. Informatico is the generic term to indicate one of the many professional figures employed in computer science in the business, industrial and scientific fields. These professions belong to the advanced tertiary sector. Since the beginning of the xxi century the term is differentiated with the operator who uses the computer as a tool for his own business. The profession of computer scientist brings together all the trades that consist of designing, coordinating or implementing the development or deployment of a computerized solution that will be made available to the operators then called users.
Born in Bronxville, New York, Ritchie graduated in physics and applied mathematics by Harvard University. In 1967 he began working at the Center for Research in Computational Sciences at Bell Labs. In 1983, he and Ken Thompson received the Turing Award for their development of generic operating system theory and especially for their implementation of the UNIX operating system.
He is famous above all for having collaborated with Dennis Ritchie, creator of the programming language C, to write the book C Programming Language, known, in the environment, as the K&R from the initials of its authors, reputed a fundamental text for the programmers. He is the creator of AWK languages, together with Alfred Aho and Peter Weinberger, and AMPL, as well as many Unix programs, such as troff.
He founded REBOL Technologies in 1997, spreading his self-developed programming language. Carl Sassenrath has been a major developer of computer languages and operating systems as well as network computing for more than 20 years. In 1985, after completing the core of the Amiga multitasking operating system, he became chief programmer at Apple, HP and Commodore.
Tim completed his higher education at Queen's College, Oxford University. He was caught in the university while hacking with his friend. Therefore, he was refused the use of computers in the university. In 1976, he received a degree in Physics from the University. In 2004, Tim won the Millennium Technology Prize, which earned him one million Euros. In 2017 he was awarded the Association for Computing Machinery (ACM) with the Turing Award of 2016, considered the Nobel of Computing.
Vinton Gray Cerf is an American computer scientist, considered one of the 'fathers' of the Internet. He graduated in mathematics and computer science at Stanford University (1965). During his subsequent stay at the University of California (UCLA) he obtained a master's degree in science and a doctorate.
John Backus was an American computer scientist. Winner of the Turing Prize in 1977 for his work in high-level programming systems, especially for his work with FORTRAN. To avoid the difficulties of programming the calculators of his time, in 1954 Backus was in charge of the direction of a research project in IBM for the project and realization of a programming language closer to the normal mathematical notation. From that project emerged the FORTRAN language, the first of the high-level programming languages that had a great, even commercial, impact on the emerging computer community. After the completion of FORTRAN, Backus was a very active member of the international committee that was in charge of the ALGOL language project.
Mark Elliot Zuckerberg is an American computer programmer, entrepreneur and multi-billionaire. During his studies at Harvard University (which he quit) he founded the social networking site Facebook in 2004 together with Eduardo Saverin, Dustin Moskovitz, Sean Parker and Chris Hughes.
