Computing

Computing is the process or act of calculation using a computer in the field of study of computers and computer programming. It is the development and using of computer technology, hardware, and software.

The science and the study of the theoretical foundations of information of and how they are applied and implemented are called computer science.

A general definition would be any activity with a goal that benefits from, requires the use of, or develops or creates computers. This would include a huge array of activities such as designing and building hardware and software systems for many purposes which would include processing, structuring, managing information, scientific studies, creating intelligent behavior, creating and using communications and entertainment media, finding and gathering information for a particular purpose and various other activities.

Data is manipulated by a machine called a computer thru a set of instructions called a computer program. From this program the computer executes instructions directly from its executable form and from its human-readable source code form a programmer can develop and study the algorithm.

According to the central processing unit type or type of computer being used a single set of source instructions converts to machine instructions.

In a computer program the execution process carries out the instructions that express the computations performed by the computer. Simple actions thru triggered sequences from the instructions produce effects according to the semantics of the instructions.

In general the testing, writing, debugging, documenting of computer programs, and maintaining source code is considered computer programming.

The source code is an artificial language that is demanding, restrictive, and unforgiving to humans written in a programming language easily translated by the computer.

Programming is used to produce the desired behavior from the machine.

Writing good source code requires knowledge of the application's domain and the domain of computer science.

Good quality software is developed by a team of domain experts in various specialized areas of development.

A programmer by definition could be any person from a hacker to a professional or to an open source contributor.
