application service provider <business, networking> (ASP) A service (usually a business) that provides remote access to an {application program} across a {network} {protocol}, typically {HTTP}. A common example is a {website} that other websites use for accepting payment by credit card as part of their {online ordering} systems. As this term is complex-sounding but vague, it is widely used by {marketroids} who want to avoid being specific and clear at all costs. (2001-03-26)
