A back quote is a symbol or punctuation mark that is found in most standard physical and logical computer and mobile keyboards or key strings. It is used in composing textual documents, sending computer commands and writing programming applications.
A back quote is also known as grave accent, left quote, open quote and push.
Besides a punctuation mark, a back quote is primarily a type of operator that has wide implementation in various operating systems and programming languages. For example when used in Perl language, the back quote executes a system command and stores the output or results within an array. Similarly, in LISP, the back quote provides a template of data structure to be built that ultimately leads to shorter code structure, interpretation of data in different forms and the selective evaluation of elements within the quote and more.
