Providing service access for internet use is the business of an Internet Service Provider (ISP). Examples of organizations that can be ISPs are commercial entities, community-based organizations, non-profit organizations, and privately-owned enterprise. An ISP can offer these forms of services – internet access, internet transit, domain name registration, web hosting, Usenet service, and collocation.
The internet is composed of a network of networks, so that any ISP may connect to a larger network and become affiliated or become a part of that network. Well-known communications companies are also ISPs, and, at the same time, a part or interlinked with a bigger network company which is also into internet service.
The internet service provider (ISP) can be classified as access providers, mailbox providers, hosting ISPs, transit ISPs, virtual ISPs, free ISPs, and wireless ISP.
