Help Desk is a department in a organization that handles customers' interactions on a product or service. Customers contact the help desk when they have a question or a problem and a product expert addresses the question to the customer's satisfaction. In a typical scenario, a help desk is a space manned by product experts from the customer support department when customers require assistance. Most companies give out an email address or a toll-free number for the customers to request help from the experts. Customers can reach the company through these channels when they need help.
