A 'computer language' is a system of communication with a computer.
A programming language is a formal language, which comprises a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms.
A command language is a language for job control in computing.It is a domain-specific and interpreted language; common examples of a command language are shell or batch programming languages.
These languages can be used directly at the command line, but can also automate tasks that would normally be performed manually at the command line. They share this domain—lightweight automation—with scripting languages, though a command language usually has stronger coupling to the underlying operating system. Command languages often have either very simple grammars or syntaxes very close to natural language, to shallow the learning curve, as with many other domain-specific languages.
Machine code is a computer program written in machine language instructions that can be executed directly by a computer's central processing unit (CPU). Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump, or an ALU operation on one or more units of data in CPU registers or memory.
Assembly language, often abbreviated asm, is any low-level programming language in which there is a very strong correspondence between the instructions in the language and the architecture's machine code instructions.Because assembly depends on the machine code instructions, every assembler has its own assembly language which is designed for exactly one specific computer architecture. Assembly language may also be called symbolic machine code.[
A markup language is a system for annotating a document in a way that is syntactically distinguishable from the text.The idea and terminology evolved from the "marking up" of paper manuscripts , which is traditionally written with a red or blue pencil on authors' manuscripts.In digital media, this "blue pencil instruction text" was replaced by tags, which indicate what the parts of the document are, rather than details of how they might be shown on some display. This lets authors avoid formatting every instance of the same kind of thing redundantly. It also avoids the specification of fonts and dimensions which may not apply to many users.
A style sheet language, or style language, is a computer language that expresses the presentation of structured documents. One attractive feature of structured documents is that the content can be reused in many contexts and presented in various ways. Different style sheets can be attached to the logical structure to produce different presentations.
One modern style sheet language with widespread use is Cascading Style Sheets (CSS), which is used to style documents written in HTML, XHTML, SVG, XUL, and other markup languages.
Configuration files are files used to configure the parameters and initial settings for some computer programs. They are used for user applications, server processes and operating system settings.
Some applications provide tools to create, modify, and verify the syntax of their configuration files; these sometimes have graphical interfaces.For other programs, system administrators may be expected to create and modify files by hand using a text editor; possible because many are human-editable plain text files. For server processes and operating-system settings, there is often no standard tool, but operating systems may provide their own graphical interfaces such as YaST or debconf.
Construction languages include all forms of communication by which a human can specify an executable problem solution to a computer. They include configuration languages, toolkit languages, and programming languages:
1.Configuration languages are languages in which software engineers choose from a limited set of predefined options to create new or custom software installations.
2.Toolkit languages are used to build applications out of toolkits and are more complex than configuration languages.
3.Scripting languages are kinds of application programming languages that supports scripts which are often interpreted rather than compiled.
4.Programming languages are the most flexible type of construction languages
Query languages or data query languages (DQLs) are computer languages used to make queries in databases and information systems.
Data Query Language is used to extract data from the database. It doesn't modify any data in the database. It describes only one query: SELECT.
A modeling language is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure.
A computer simulation language is used to describe the operation of a simulation on a computer.There are two major types of simulation: continuous and discrete event though more modern languages can handle more complex combinations.
Most languages also have a graphical interface and at least a simple statistic gathering capability for the analysis of the results. An important part of discrete-event languages is the ability to generate pseudo-random numbers and variants from different probability distributions.
