Translator (computing)

A translator or programming language processor is a generic term that can refer to anything that converts code from one computer language into another.[1][2] A program written in high-level language is called source program. These include translations between high-level and human-readable computer languages such as C++ and Java, intermediate-level languages such as Java bytecode, low-level languages such as the assembly language and machine code, and between similar levels of language on different computing platforms, as well as from any of the above to another.[1]

The term is also used for translators between software implementations and hardware implementations (ASICs microchips) of the same program, and from software descriptions of a microchip to the logic gates needed to build it.

Different types of translators

The 3 different types of translators are normally as follows:

Compiler

A compiler is a translator used to convert high-level programming language to low-level programming language. It converts the whole program in one session and reports errors detected after the conversion. The compiler takes time to do its work as it translates high-level code to lower-level code all at once and then saves it to memory. A compiler is processor-dependent and platform-dependent. It has been addressed by alternate names as the following: special compiler, cross-compiler and, source-to-source compiler.[3][1][4]

Interpreter

The interpreter is similar to a compiler, as it is a translator used to convert high-level programming language to low-level programming language. The difference is that it converts the program one line of code at a time and reports errors when detected, while also doing the conversion. An interpreter is faster than a compiler as it immediately executes the code upon reading the code. It is often used as a debugging tool for software development as it can execute a single line of code at a time. An interpreter is also more portable than a compiler as it is processor-independent, you can work between different hardware architectures.[3][1][4]

Assembler

An assembler is a translator used to translate assembly language into machine language. It has the same function as a compiler for the assembly language but works like an interpreter. Assembly language is difficult to understand as it is a low-level programming language. An assembler translates a low-level language, such as an assembly language to an even lower-level language, such as the machine code.[3][1]
