a person who provides the large computing systems and data storage required for other users to connect to the network of computers connected by a common protocol. In the law of the European Union an ISP provides information society services. To facilitate the function of those like ISPS special defences have been given to them to protect them from the claims for damages or prosecutions which could otherwise paralyse their business or divert others from entering. See e.g. CACHING, CONDUIT or HOSTING.
