Opinion: Why all children must learn code

Across the world, the conversion of information into a digital format—also called "digitalization"—has increased productivity in the public and private sectors. As a result, virtually every country in the world is working ...

A 'simulation booster' for nanoelectronics

Two research groups from ETH Zurich have developed a method that can simulate nanoelectronics devices and their properties realistically, quickly and efficiently. This offers a ray of hope for the industry and data center ...

MicroRNA comprehensively analyzed

Messenger RNA transmits genetic information to the proteins, and microRNA plays a key role in the regulation of gene expression. Scientists from the Moscow Institute of Physics and Technology and the Research Centre for Medical ...

2I/Borisov: Interstellar comet with a familiar look

A new comet discovered by amateur astronomer Gennady Borisov is an outcast from another star system, yet its properties are surprisingly familiar, a new study led by Jagiellonian University researchers shows. The team's findings ...

Hello, world! A new approach for physics in de Sitter space

For decades, physicists have been attempting to reconcile quantum mechanics, the physics of the very small, with gravity, the physics of the very large. While many academics are working on quantum gravity, they often use ...

At 82, NASA pioneer Sue Finley still reaching for the stars

Sue Finley began work at the Jet Propulsion Laboratory as the US prepared to launch its first satellite into orbit in 1958, racing to match the Soviet Union, which had accomplished the feat months earlier.

Computer program

Computer programs (also software programs, or just programs) are instructions for a computer. A computer requires programs to function, typically executing the program's instructions in a central processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled), enables a programmer to study and develop the algorithm.

Computer source code is often written by professional computer programmers. Source code is written in a programming language that usually follows one of two main paradigms: imperative or declarative programming. Source code may be converted into an executable file (sometimes called an executable program or a binary) by a compiler. Alternatively, computer programs may be executed by a central processing unit with the aid of an interpreter, or may be embedded directly into hardware (in which case it is more widely known under the term 'firmware', as something 'between' software and hardware).

Computer programs may be categorized along functional lines: system software and application software. And many computer programs may run simultaneously on a single computer, a process known as multitasking.
