kinds of programming
The educational goal of this subchapter is to introduce the basic different kinds of programming in common use.
The two major kinds of programming are systems programming and applications programming.
kinds of programming
There are two basic kinds of programming: system and application.
System programming deals with the use of a computer system. This includes such things as the operating system, device drivers for input and output devices, and systems utilities.
Application programming deals with the programs directly used by most people.
Application programming is generally divided further into scientific and business programming.
Scientific programming is work in the scientific, engineering, and mathematical fields. Often the programmers are the researchers who use the programs.
Business programming is work in the data processing field, including large scale business systems, web-based businesses, and office applications. It is exceedingly rare for these kinds of programs to be created by the person who uses them.
Another large category of programming is programming for personal or home use. This includes games. Historically, many advances in computer science occurred in the development of computer and video games.
Embedded systems are programs that are built into specific hardware, such as the computer systems in an automobile or microwave oven. These programs combine features of operating systems and application program into a single monolithic system.
Scripting is a simplified version of programming originally intended for use primarily by non-programmers. In practice, most non-programmers have trouble with scripting languages. Some professional programmers have built very useful, sometimes intricate systems using scripting languages, especially those contained in office software (such as word processors or spreadsheets).
free music player coding example
Coding example: I am making heavily documented and explained open source code for a method to play music for free almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

Work on this project is very slow because I am homeless. I am available for work if someone can provide an indoor place to work in Costa Mesa, California, electricity, internet connections, a flat raised working surface (such as a table or desk), a sitting device (such as a chair or stool), and a fully functional reasonably modern used computer. Im already homeless, so you dont need to pay me (and I understand how much business people hate the minimum wage law). Just give me a chance to work.
Because I no longer have the computer and software to make PDFs, the book is available as an HTML file, which you can convert into a PDF.
