'''Computer programming''' or '''coding''' is the composition of sequences of instructions, called [[computer program|programs]], that [[computer]]s can follow to perform tasks.<ref>{{cite web|url=http://yearofcodes.tumblr.com/what-is-coding|title=What is coding|last=Bebbington|first=Shaun|year=2014|website=Tumblr|url-status=live|archive-url=https://web.archive.org/web/20200429195646/https://yearofcodes.tumblr.com/what-is-coding|archive-date=2020-04-29|access-date=2014-03-03}}</ref><ref>{{cite web|url=http://yearofcodes.tumblr.com/what-is-programming|title=What is programming|last=Bebbington|first=Shaun|year=2014|website=Tumblr|url-status=live|archive-url=https://web.archive.org/web/20200429195958/https://yearofcodes.tumblr.com/what-is-programming|archive-date=2020-04-29|access-date=2014-03-03}}</ref> It involves designing and implementing [[algorithm]]s, step-by-step specifications of procedures, by writing [[source code|code]] in one or more [[programming language]]s. Programmers typically use [[high-level programming language]]s that are more easily intelligible to humans than [[machine code]], which is directly executed by the [[central processing unit]]. Proficient programming usually requires expertise in several different subjects, including knowledge of the [[Domain (software engineering)|application ___domain]], details of programming languages and generic code [[library (computing)|libraries]], specialized algorithms, and [[Logic#Formal logic|formal logic]].
