No problem

Steve Jobs is an American IT specialist, who in 1976, together with Steve Wozniak and Ronald Wayne, created Apple – one of the most extensive and most expensive valued brands in the world, whose products have impressed and influenced the development of modern technologies around the world. The company is known, among others from the production of MacIntosh computers and electronic devices such as iPod, iPad, or iPhone.

However, their first money Steve Jobs and Steve Wozniak, earned from the production of so-called blue-boxes. They were small machines designed to cheat the telephone system. At the turn of the 1960s and 1970s, telephone calls were costly. Blue-boxes allowed making long distance calls without paying for them.

Linus Torvalds is a Finnish programmer whose work has been of great importance for the development of free software. During his free time, he used a home computer, and the inspiration to create Linux was the educational MINIX system. In 1991 the first version of Linux was created. In 2012 Torvalds was honored with the Millennium Technology Prize by Technology Academy Finland.

Marvin Lee Minsky was an American cognitive scientist. Marvin was one of the few people in the computer world whose visionary revolutionized thinking about the computer. He was fascinated by the intelligence and thinking of man from college. From the early 1950s, he developed computational concepts, delved into human psychological processes, from which he consequently created the theory of how to equip machines with intelligence. In 1959 he initiated the MIT Artificial Intelligence Project. Marvin Lee Minsky was a co-founder of the AI laboratory at MIT. His colleague John McCarthy was a co-creator of the term ‘artificial intelligence’.

In 1936 German Konrad Zuse created the Z1 counting machine. The following years were devoted to improving the version for Z2, Z3 then Z4. The machines were intended only for military needs. The calculations were performed on numbers recorded in the binary system, i.e. a floating point representation. The machine was controlled by a program recorded on a perforated tape. Instead of mechanical parts, electromagnetic relays were used in the machines. The Z4 was used and operated until the late 1950s.

Charles Wheatstone (born in 1802, died in 1875) English inventor considered an expert in the field of codes. In 1857 he created a system that reads and writes information on perforated tape. He developed the wheel cryptographer and its cipher called the “Wheatstone cipher”, later known as the “Playfair cipher,” helped create the first records on computers.

Gottfried Wilhelm Leibniz (born 1646, died 1716) is considered the initiator of computer science, the innovator of differential and integral calculus. His interests were machines and clocks. His work was to build one of the first calculating machines in 1964, which used the zero-one method of writing numbers. His work has survived to this day, even in libraries to this day, use the classic numerical catalogs. These catalogs are the prototype of today’s databases.

Donald Knuth retired professor at Stanford University, an American computer scientist is known for his enormous commitment to the IT industry. He is called the pioneer or father of algorithms. He is the author of the work “The Art of Computer Programming”, prepared the TeX program and developed the METAFONT language.

James Gosling is a Canadian who was born in 1955, has had many IT successes. He is known as the father of developed basics in Java, and also prepared the first version of the virtual machine. James Gosling is the creator of the implementation of Emacs, his contribution to the construction of NeWS is very well known. In 2007 he was awarded the Order of Canada, he is a member of the National Academy of Engineering.

An outstanding American IT specialist who has repeatedly made his mark in the IT industry. At first, he was a co-creator of the programming language B developed at Bell Labs in 1969. He then developed the C language with Ken Thompson and Bran Kernighan in the early 1970s. In the meantime, he was a co-creator of the Unix operating system. Certainly influenced the creation of modern programming languages. In 1983, Ritchie received the Turing Award, awarded every year for outstanding achievements in computer science.

Vinton Gray Cerf was born in 1943. He is considered one of the creators of the Internet. After graduating from Stanford University and the University of California, found employment at DARPA. He played a key role in creating the basic network protocol – TCP / IP, he also wrote the first commercial email program. In addition to scientific work, Vint Cerf was also a member of the board of The Internet Corporation for Assigned Names and Numbers (ICANN), awarded and standardized domain names, administering IP resources and managing DNS servers.
