Answer:
extranet
Step-by-step explanation:
An extranet allows outside companies to exchange data and carry on transactions by providing them with web browser based access to some specific parts of a business's intranet. This is done to reduce time and costs, making certain transactions more fluid.
For example, a supplier may have access to your company's inventory of their specific products, and when the supply runs low they might notify your company about it. Or they might use this information in order to offer some specific discounts regarding the products you are using.
