Famous Computer Programmers
Let us share with you on best Appedology blogs about Famous computer programmers is a person capable of designing and changing computer programs. Regardless of what sort of programmer, each and everyone contributes something to the world, no matter how insignificant. And there are a few who have contributed over the span of career above what a single programmer normally does. Such Famous computer programmers are leaders in their respective fields, and each has done something that has totally transformed the manner in which humans view information and media. Here is the list of famous computer programmers:
Augusta Ada King, most widely known as Ada Lovelace, was an English mathematician and the first computer programmer in the world, who was best known for her work on Charles Babbage’s early general-purpose mechanical machine, the Analytical Engine. The documents she made for the Analytical Engine contain what is known as the very first algorithm explicitly developed for the purpose of being run by a processor or, in other words, the first computer program in the world. From the beginning, Ada was a brilliant girl with an unusual mentality who believed that one-day machines would evolve from being used merely to crunch numbers — utterly contrary to the prevailing belief at the period. Ada’s biggest influence came from her father and without her who knows how long a computer program will take another human to build.
Niklaus Emil Wirth is a Swiss computer scientist who is regarded as a pioneer of computer programming among other fields in software engineering. He is best known for designing several programming languages, including the highly popular Pascal, Euler, Algol W, Modula, Modula-2, Oberon, Oberon-2, and Oberon-07. He also designed the simple programming language PL/0 to illustrate compiler design which formed the basis for many university compiler design classes. Niklaus had previously worked on part of the design and implementation team for the Lilith and Oberon operating systems as well as the Lola digital hardware design and simulation system. Wirth’s pioneering work and development of innovative computer languages helped him win the prestigious Turing Award in 1984.
Bill Gates is probably one of the most influential computer programmers ever, an American business magnate, computer programmer, Computing inventor, businessman, and philanthropist. He is Microsoft’s co-founder, chief CEO and acting president, which is the biggest personal-computer tech firm in the world. He is the best-known pioneer of the personal computer movement and has helped to create Windows, the world’s most commonly used operating system. In addition to running the company’s corporate side, Gates often directly supervised every single release that the organization sent out for the first 5 years at Microsoft, sometimes correcting the ones he found to be inaccurate or faulty. He is generally admired for his optimism and keen strategic strategy aside from his programming abilities but is strongly criticized for his anti-competitive market practices.
Stages in Evolution of Programming Languages
A computer must be given instructions in a language of programming that it understands. A programming language is an abstract language that can be used to monitor machine behavior. Programming languages, like human languages, are defined to decide structure and context, respectively, by the use of syntactic and semantic rules. Programming languages are used to promote cooperation on the role of knowledge organization and manipulation and to communicate algorithms accurately. Many writers extend the word “programming language” to languages capable of communicating all imaginable algorithms; often, the word “machine language” is used for a more restricted artificial language.
Programming languages have been around for over 200 years, believe it or not, since the invention of the punch-card-programmable Jacquard loom. It was not a programming language in the current sense — there was no calculation and no logic — but it began a cascade that would ultimately lead to the Analytical Engine of Charles Babbage, and the 1842 deconstruction of his research by Ada Lovelace that led to the first computer system. However, it was a whole hundred years before the first electrical, programmable computers burst into existence. Machine-specific assembly language in the 1940s was undoubtedly the first (vaguely) human-readable programming language, but by the 1950s computer engineers discovered that assembly language was much too laborious and error-prone to build whole programs out of — and so the first functional programming language was created in 1955: FORTRAN (FORmula TRANslator). In the next few years LISP (LISt Processor), ALGOL (ALGOrithmic Language), and COBOL (COmmon Business Oriented Language) will follow — and as they suggest, the rest is history. Today almost every language is derived from one of these first four languages — and indeed, FORTRAN, LISP, and COBOL are still being used extensively by big, lumbering organizations such as the National Weather Service and the US Postal Service. BASIC was invented by 1964, and then C published in 1969. Unix was renownedly rewritten into C — the first big OS not to be written in assembly language — and currently, Linux is written nearly exclusively in C, and both Windows and Mac OS X have huge swaths of their programming in C.
Generations of Programming Languages
The programming languages were developed in a staggered manner throughout the year. Through development process has made the programming language user-friendlier, simpler to use, and more efficient. The growing process of progress made in programming language development may be called a generation. The programming language can be divided into five separate generations of programming languages in terms of their performance reliability and robustness;
History of programming languages
First-generation of programming languages (1GPL)
The programming language of the first generation is often called low-level programming language since it was used to program the computer system at a very low abstraction stage. That is to say, at the computer level. The artificial language is the first generation programming language, often referred to as the operating system’s natural tongue. In the machine language, only a binary number is dealt with by a programmer.
Second-generation of programming languages (2GPL)
The programming language of the second generation also belongs to the low-level programming language category. The language of the second generation includes assembly languages which use the mnemonics concept for the writing program. Symbolic names are used in the assembly language to describe the opcode and the instruction operand portion.
Third-generation of programming languages (3GPL)
The programming languages of the third generation were built to address the complex shortcomings of programming languages of the first and second generations. The third and later generation languages are considered a high-level language as they require the programmer to focus solely on the semantics of the programs without understanding the computer system’s internal architecture.
Fourth-generation of programming languages (4GPL)
This generation’s languages were considered to be very high-level programming languages that needed a great deal of time and effort to impact programmer productivity. The programming languages of the fourth generation were planned and built to reduce the time, expense, and effort needed for the creation of different software applications.
Fifth-generation of programming languages (5GPL)
This generation’s programming languages rely primarily on constraint programming. Artificial Intelligence and Artificial Neural Networks are the key domains of which the fifth generation programming language is used
Factors Influencing the Evolution of Programming Languages
Following are the factors influencing the evolution of programming language:
- Purpose. This stipulates the programming language goal.
- Programmer experience.
- Ease of Development and Maintenance.
- Performance and Efficiency.
- Availability of IDE.
- Error Checking and Diagnosis.
