Computer program | Britannica

Computer program, detailed plan or procedure for solving a problem with a computer; more specifically, an unambiguous, ordered sequence of computational instructions necessary to achieve such a solution. The distinction between computer programs and equipment is often made by referring to the former as software and the latter as hardware.

Programs stored in the memory of a computer enable the computer to perform a variety of tasks in sequence or even intermittently. The idea of an internally stored program was introduced in the late 1940s by the Hungarian-born mathematician John von Neumann. The first digital computer designed with internal programming capacity was the EDVAC (acronym for Electronic Discrete Variable Automatic Computer), constructed in 1949.

A program is prepared by first formulating a task and then expressing it in an appropriate computer language, presumably one suited to the application. The specification thus rendered is translated, commonly in several stages, into a coded program directly executable by the computer on which the task is to be run. The coded program is said to be in machine language, while languages suitable for original formulation are called problem-oriented languages. A wide array of problem-oriented languages has been developed, some of the principal ones being COBOL (Common Business-Oriented Language), FORTRAN (Formula Translation), BASIC (Beginner’s All-Purpose Symbolic Instruction Code), and Pascal. (See also computer programming language.)

Computers are supplied with various programs designed primarily to assist the user to run jobs or optimize system performance. This collection of programs, called the operating system, is as important to the operation of a computer system as its hardware. Current technology makes it possible to build in some operating characteristics as fixed programs (introduced by customer orders) into a computer’s central processing unit at the time of manufacture. Relative to user programs, the operating system may be in control during execution, as when a time-sharing (q.v.) monitor suspends one program and activates another, or at the time a user program is initiated or terminated, as when a scheduling program determines which user program is to be executed next. Certain operating-system programs, however, may operate as independent units to facilitate the programming process. These include translators (either assemblers or compilers), which transform an entire program from one language to another; interpreters, which execute a program sequentially, translating at each step; and debuggers, which execute a program piecemeal and monitor various circumstances, enabling the programmer to check whether the operation of the program is correct or not.

Computer program – Wikipedia

Instructions to be executed by a computer

A computer program is a collection of instructions[1] that can be executed by a computer to perform a specific task. Most computer devices require programs to function properly.

A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler or assembler can derive machine code—a form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter.

A collection of computer programs, libraries, and related data are referred to as software. Computer programs may be categorized along functional lines, such as application software and system software. The underlying method used for some calculation or manipulation is known as an algorithm.

History[edit]

Code-breaking algorithms have existed for centuries. In the 9th century, the Arab mathematician Al-Kindi described a cryptographic algorithm for deciphering encrypted code, in A Manuscript On Deciphering Cryptographic Messages. He gave the first description of cryptanalysis by frequency analysis, the earliest code-breaking algorithm.[2]

Early programmable machines[edit]

The earliest programmable machines preceded the invention of the digital computer. As early as the 9th century, a programmable music sequencer was invented by the Persian Banu Musa brothers, who described an automated mechanical flute player in the Book of Ingenious Devices.[3][4] In 1206, the Arab engineer Al-Jazari invented a programmable drum machine where musical mechanical automata could be made to play different rhythms and drum patterns.[5] In 1801, Joseph-Marie Jacquard devised a loom that would weave a pattern by following a series of perforated cards. Patterns could be woven and repeated by arranging the cards.[6]

Analytical Engine[edit]

In 1837, Charles Babbage was inspired by Jacquard’s loom to attempt to build the Analytical Engine.[6]
The names of the components of the calculating device were borrowed from the textile industry. In the textile industry, yarn was brought from the store to be milled. The device would have had a “store”—memory to hold 1,000 numbers of 40 decimal digits each. Numbers from the “store” would then have then been transferred to the “mill” (analogous to the CPU of a modern machine), for processing. And a “thread” being the execution of programmed instructions by the device. It was programmed using two sets of perforated cards—one to direct the operation and the other for the input variables.[6][7] However, after more than 17,000 pounds of the British government’s money, the thousands of cogged wheels and gears never fully worked together.[8]

During a nine-month period in 1842–43, Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea. The memoir covered the Analytical Engine. The translation contained Note G which completely detailed a method for calculating Bernoulli numbers using the Analytical Engine. This note is recognized by some historians as the world’s first written computer program.[9]

A variety of tasks to develop computers based on the stored-program architecture began round this time. Have played a lot of the LAPTOP video games within the list. Circuits, computer chips, graphic playing cards, sound playing cards, reminiscence (RAM), motherboard, displays, energy supplies, cables, keyboards, printers and “mice” enter gadgets are all hardware.

Whereas it is possible to write computer programs as long lists of numbers ( machine language ) and while this method was used with many early computers, sixty seven this can be very tedious and probably error-inclined to do so in apply, particularly for sophisticated applications.

Computer programmers write and take a look at code that allows computer applications and software program packages to operate correctly. The Jacquard loom was one of the first programmable gadgets. Excessive occurrences of software program piracy in Asian nations condemned computers in these countries that connected to the Web and ran pirate variations of Microsoft Home windows to be infected by the Conficker worm.…
