In computing, a shell is a computer program that exposes an operating system 's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [ 1][ 2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming ...

Such settings are also called presets or factory presets, especially for electronic devices. Default values are standards values that are universal to all instances of the device ...
In information security, computer science, and other fields, the principle of least privilege (PoLP), also known as the principle of minimal privilege (PoMP) or the principle of least authority (PoLA), requires that in a particular abstraction layer of a computing environment, every module (such as a process, a user, or a program, depending on the subject) must be able to access only the ...
When compiled and run, it will give the output " Hello, world! ". A programming language is a system of notation for writing computer programs. [ 1 ] Programming languages are described in terms of their syntax (form) and semantics (meaning), usually defined by a formal language.
