A [[compiler]] is a translator used to convert [[high-level programming language]] to [[low-level programming language]]. It converts the whole [[Computer program|program]] in one session and reports [[Software bug|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 [[Central processing unit|processor]]-dependent and [[Cross-platform software|platform-dependent]].
It has been addressed by alternate names as the following: special compiler, cross-compiler and, source-to-source compiler.<ref>{{Cite web|url=https://teachcomputerscience.com/translators/|title=Translators | Purpose, Types, Examples & Advantages|date=11 January 2018}}</ref><ref>{{Cite web|url=https://www.microcontrollertips.com/compilers-translators-interpreters-assemblers-faq/|title = What are compilers, translators, interpreters, and assemblers?}}</ref><ref name="Pasteur_2008">{{cite book |author-first1=Katja |author-last1=Schuerer |author-first2=Catherine |author-last2=Letondal |author-first3=Eric |author-last3=Deveaud |date=2008-02-04 |orig-year=2003-01-06 |publisher=[[Pasteur Institute]] |title=Introduction to Programming using Python - Programming Course for Biologists at the Pasteur Institute |chapter=Chapter 5.

=== Interpreter ===
Line 21:
The [[Interpreter (computing)|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 [[computer code|code]] at a time. An interpreter is also more portable than a compiler as it is [[Central processing unit|processor]]-independent, you can work between different [[Computer hardware|hardware]] [[Computer architecture|architectures]].<ref>{{Cite web|url=https://teachcomputerscience.com/translators/|title=Translators | Purpose, Types, Examples & Advantages|date=11 January 2018}}</ref><ref>{{Cite web|url=https://www.microcontrollertips.com/compilers-translators-interpreters-assemblers-faq/|title = What are compilers, translators, interpreters, and assemblers?}}</ref><ref name="Pasteur_2008">{{cite book |author-first1=Katja |author-last1=Schuerer |author-first2=Catherine |author-last2=Letondal |author-first3=Eric |author-last3=Deveaud |date=2008-02-04 |orig-year=2003-01-06 |publisher=[[Pasteur Institute]] |title=Introduction to Programming using Python - Programming Course for Biologists at the Pasteur Institute |chapter=Chapter 5.

=== Assembler ===
{{main|Assembly language#Assembler}}
An [[Assembler (computing)|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]].<ref>{{Cite web|url=https://teachcomputerscience.com/translators/|title=Translators | Purpose, Types, Examples & Advantages|date=11 January 2018}}</ref><ref>{{Cite web|url=https://www.microcontrollertips.com/compilers-translators-interpreters-assemblers-faq/|title = What are compilers, translators, interpreters, and assemblers?}}</ref>
