The modern binary number system, the basis for binary code, is an invention by Gottfried Leibniz in 1689 and appears in his article Explication de l'Arithmétique Binaire (English: Explanation of the Binary Arithmetic) which uses only the characters 1 and 0, and some remarks on its usefulness. Leibniz's system uses 0 and 1, like the modern ...
She believed that programming should be simplified with an English-based computer programming language. Her compiler converted English terms into machine code understood by computers. By 1952, Hopper had finished her program linker (originally called a compiler ), which was written for the A-0 System .
Arithmetic values thought to have been represented by parts of the Eye of Horus. The scribes of ancient Egypt used two different systems for their fractions, Egyptian fractions (not related to the binary number system) and Horus-Eye fractions (so called because many historians of mathematics believe that the symbols used for this system could be arranged to form the eye of Horus, although this ...
Gottfried Wilhelm Leibniz (1646–1716) developed logic in a binary number system and has been called the "founder of computer science". [19] In 1702, Gottfried Wilhelm Leibniz developed logic in a formal, mathematical sense with his writings on the binary numeral system.
[23] [24] The computers were programmed with a language called "Basic" (no relation to the BASIC programming language developed at Dartmouth at about the same time). [25] The software also had an interpreter which was made up of a series of routines and an executive (like a modern-day operating system ), which specified which programs to run ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [ 1 ] [ 2 ] It involves designing and implementing algorithms , step-by-step specifications of procedures, by writing code in one or more programming languages .
Invented the concept of a hardware abstraction layer called the BIOS, with both conceptually laying the foundation to all DOS-based operating systems on personal computers. Worked on diskette track buffering schemes, read-ahead algorithms, virtual disk drives, and file system caching .
