Figuratively speaking, applications software sits on top of systems software because it is unable to run itself without the operating system and system utilities.Īpplication is just another word for program or software program, like the packaged programs, Microsoft Word (word processing) or Adobe Photoshop (graphics). Debugger, as the name implies, is the software to detect and correct errors in the source code.Īpplications software (also called end-user programs) enable you to complete specific tasks, like word processing, making spreadsheets, working with pictures, planning landscaping, playing games, etc. Besides Python IDLE, Netbeans, Eclipse, Atom, Lazarus is few other examples of IDEs. In order to simplify the program development, there is a software called Integrated Development Environment (IDE) consisting of a text editor, building tools, and debugger.Ī program can be typed, compiled, and debugged from the IDE directly. Examples of high-level languages include C++, Java, Python, etc. Hence, translators are needed to translate high-level language codes into machine language. However, these languages are not directly understood by the computer. Instructions are using English sentences and each high-level language follows a set of rules, similar to natural languages. High-level languages are machine-independent and are simpler to write code into. But one major drawback of writing a code in this language is that the code is computer specific, i.e., the code written for one type of CPU cannot be used for another type of CPU. To simplify the writing of code, assembly language was developed that allowed usage of English-like words and symbols instead of 1s and 0s. Also finding errors in the code written in machine language is difficult.
Machine language uses 1s and 0s to write instructions that are directly understood and executed by the computer.īut writing a code in machine language is difficult as one has to remember all operation codes and machine addresses.
Low-level languages are machine-dependent languages and include machine language and assembly language.
Two major categories of computer programming languages are low-level languages and high-level languages. So different types of computer programming languages are developed to simplify the coding. It is very difficult for a human being to write instructions in the form of 1s and 0s.
