A Helpdesk is an information and assistance resource that troubleshoots problems with computers and similar products. Corporations often provide Helpdesk support to their customers via a toll-free number, website and/or e-mail. There are also in-house Helpdesks geared toward providing the same kind of help for employees only. Some schools offer classes in which they perform similar tasks as a Helpdesk. It is often referred to as the "hell desk" by those who work there.

A typical Helpdesk has several functions. It provides the users a central point to receive help on various computer issues. The Helpdesk typically manages its requests via Helpdesk software that allows them to track user requests with a unique ticket number.
