Requirements are basically demands from clients which we document so that we can achieve the Goal.

Requirements are things we need to do in order to achieve a need or Goal.

In Simple words Requirement is a need of the client.

Needs are Goals and objectives a business must achieve by gathering the requirements from the clients.
