What term refers to a person using a computer to perform routine tasks other than systems administration

end user

Explanation:

An end user refers to a person using a computer system to perform routine tasks such as listening to music, formatting a document, creating graphic designs, surfing the web, etc., rather than perform systems administration. Thus, an end user is the individual for whom a software application or computer system is created for, especially to perform basic or routine tasks.

For example, a network or system administrator is saddled with the responsibility of implementing changes on an end user's network and network devices in order to get an optimum level of performance.
