An\u00c2\u00a0Internet Service Provider\u00c2\u00a0(ISP) is an organization that provides services for accessing, using, or participating in the\u00c2\u00a0Internet. Internet service providers can be organized in various forms, such as commercial,\u00c2\u00a0community-owned,\u00c2\u00a0non-profit, or otherwise\u00c2\u00a0privately owned.<\/p>\n
Internet services typically provided by ISPs include\u00c2\u00a0Internet access,\u00c2\u00a0Internet transit,\u00c2\u00a0domain name\u00c2\u00a0registration,\u00c2\u00a0web hosting,\u00c2\u00a0Usenet\u00c2\u00a0service, and\u00c2\u00a0colocation.<\/p>\n
Classifications:<\/span><\/p>\n Access providers:<\/span><\/p>\n <\/span>Access provider ISPs provide\u00c2\u00a0Internet access, employing a range of technologies to connect users to their network.\u00c2\u00a0Available technologies have ranged from computer modems with\u00c2\u00a0acoustic couplers\u00c2\u00a0to telephone lines, to television cable (CATV),\u00c2\u00a0Wi-Fi, and fiber optics.<\/p>\n For users and small businesses, traditional options include copper wires to provide\u00c2\u00a0dial-up, DSL, typically\u00c2\u00a0asymmetric digital subscriber line\u00c2\u00a0(ADSL),\u00c2\u00a0cable modem\u00c2\u00a0or\u00c2\u00a0Integrated Services Digital Network\u00c2\u00a0(ISDN) (typically\u00c2\u00a0basic rate interface). Using\u00c2\u00a0fiber-optics\u00c2\u00a0to end users is called\u00c2\u00a0Fiber To The Home\u00c2\u00a0or similar names.<\/p>\n For customers with more demanding requirements (such as medium-to-large businesses, or other ISPs) can use higher-speed DSL (such as\u00c2\u00a0single-pair high-speed digital subscriber line),\u00c2\u00a0Ethernet,\u00c2\u00a0metropolitan Ethernet,\u00c2\u00a0gigabit Ethernet,\u00c2\u00a0Frame Relay, ISDN\u00c2\u00a0Primary Rate Interface,\u00c2\u00a0ATM (Asynchronous Transfer Mode)\u00c2\u00a0and\u00c2\u00a0synchronous optical networking\u00c2\u00a0(SONET).<\/p>\n Wireless access\u00c2\u00a0is another option, including\u00c2\u00a0cellular\u00c2\u00a0and\u00c2\u00a0satellite Internet access.<\/p>\n Mailbox providers:<\/span><\/p>\n A\u00c2\u00a0mailbox provider\u00c2\u00a0is an organization that provides services for hosting electronic mail domains with access to storage for mail boxes. It provides\u00c2\u00a0email servers\u00c2\u00a0to send, receive, accept, and store email for\u00c2\u00a0end users\u00c2\u00a0or other organizations.<\/p>\n Many mailbox providers are also access providers,\u00c2\u00a0while others are not (e.g.,\u00c2\u00a0Gmail,\u00c2\u00a0Yahoo! Mail,\u00c2\u00a0Outlook.com,\u00c2\u00a0AOL Mail,\u00c2\u00a0Po box). The definition given in\u00c2\u00a0RFC 6650\u00c2\u00a0covers\u00c2\u00a0email hosting services, as well as the relevant department of companies, universities, organizations, groups, and individuals that manage their mail servers themselves. The task is typically accomplished by implementing\u00c2\u00a0Simple Mail Transfer Protocol\u00c2\u00a0(SMTP) and possibly providing access to messages through\u00c2\u00a0Internet Message Access Protocol\u00c2\u00a0(IMAP), the\u00c2\u00a0Post Office Protocol,\u00c2\u00a0Webmail, or a proprietary protocol.<\/p>\n Hosting ISPs:<\/span><\/p>\n Internet hosting services\u00c2\u00a0provide email, web-hosting, or online storage services. Other services include\u00c2\u00a0virtual server, cloud services, or physical server operation.<\/p>\n Transit ISPs:<\/span><\/p>\n Just as their customers pay them for Internet access, ISPs themselves pay upstream ISPs for Internet access. An upstream ISP usually has a larger network than the contracting ISP or is able to provide the contracting ISP with access to parts of the Internet the contracting ISP by itself has no access to.<\/p>\n In the simplest case, a single connection is established to an upstream ISP and is used to transmit data to or from areas of the Internet beyond the home network; this mode of interconnection is often cascaded multiple times until reaching a\u00c2\u00a0tier 1 carrier. In reality, the situation is often more complex. ISPs with more than one\u00c2\u00a0point of presence\u00c2\u00a0(PoP) may have separate connections to an upstream ISP at multiple PoPs, or they may be customers of multiple upstream ISPs and may have connections to each one of them at one or more point of presence.\u00c2\u00a0Transit ISPs provide large amounts of\u00c2\u00a0bandwidth\u00c2\u00a0for connecting hosting ISPs and access ISPs.<\/p>\n Virtual ISPs:<\/span><\/p>\n A\u00c2\u00a0virtual ISP\u00c2\u00a0(VISP) is an operation that purchases services from another ISP, sometimes called a\u00c2\u00a0wholesale ISP\u00c2\u00a0in this context,\u00c2\u00a0which allow the VISP’s customers to access the Internet using services and infrastructure owned and operated by the wholesale ISP. VISPs resemble\u00c2\u00a0mobile virtual network operators\u00c2\u00a0and\u00c2\u00a0competitive local exchange carriers\u00c2\u00a0for voice communications.<\/p>\n Free ISPs:<\/span><\/p>\n Free ISPs are Internet service providers that provide service free of charge. Many free ISPs display advertisements while the user is connected; like commercial\u00c2\u00a0television, in a sense they are selling the user’s attention to the advertiser. Other free ISPs, sometimes called\u00c2\u00a0freenets, are run on a nonprofit basis, usually with volunteer staff.<\/p>\n Wireless ISP:<\/span><\/p>\n A\u00c2\u00a0wireless Internet service provider\u00c2\u00a0(WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking, or proprietary equipment designed to operate over open 900\u00c2\u00a0MHz, 2.4\u00c2\u00a0GHz, 4.9, 5.2, 5.4, 5.7, and 5.8\u00c2\u00a0GHz bands or licensed frequencies such as 2.5\u00c2\u00a0GHz (EBS\/BRS), 3.65\u00c2\u00a0GHz (NN) and in the UHF band (including the MMDS frequency band) and LMDS.<\/p>\n ISPs may engage in\u00c2\u00a0peering, where multiple ISPs interconnect at\u00c2\u00a0peering points\u00c2\u00a0or\u00c2\u00a0Internet exchange points\u00c2\u00a0(IXPs), allowing routing of data between each network, without charging one another for the data transmitted\u00e2\u20ac\u201ddata that would otherwise have passed through a third upstream ISP, incurring charges from the upstream ISP.<\/p>\n ISPs requiring no upstream and having only customers (end customers or peer ISPs) are called\u00c2\u00a0Tier 1 ISPs.<\/p>\n Network hardware, software and specifications, as well as the expertise of network management personnel are important in ensuring that data follows the most efficient route, and upstream connections work reliably. A tradeoff between cost and efficiency is possible.<\/p>\n The above is a basic about Internet Service Provider.
