Computer Application : HTML The ISP | Internet Service Provider An Internet service provider (ISP) is an organization that provides services for accessing, using, or participating in the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. Internet services typically provided by ISPs include Internet access, Internet transit, domain name registration, web hosting, Usenet service, and colocation. (0:10 - 1:01) History[edit] The Internet was developed as a network between government research laboratories and participating departments of universities. By the late 1980s, a process was set in place towards public, commercial use of the Internet. The remaining restrictions were removed by 1995, 4 years after the introduction of the World Wide Web.[1] In 1989, the first ISPs were established in Australia,[2] and the United States. In Brookline, Massachusetts, The World became the first commercial ISP in the US. Its first customer was served in November 1989 ( 1:01 - 3:11) CLassification : Access providers ISP[edit] ISPs provide Internet access, employing a range of technologies to connect users to their network.[34] Available technologies have ranged from computer modems with acoustic couplers to telephone lines, to television cable (CATV), wireless Ethernet (wi-fi), and fiber optics. Hosting ISPs[edit] Internet hosting services provide email, web-hosting, or online storage services. Other services include virtual server, cloud services, or physical server operation. Transit ISPs 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. Virtual ISPs[edit] A virtual ISP (VISP) is an operation that purchases services from another ISP, sometimes called a wholesale ISP in this context,[43] which allow the VISP's customers to access the Internet using services and infrastructure owned and operated by the wholesale ISP. VISPs resemble mobile virtual network operators and competitive local exchange carriers for voice communications. Free ISPs[edit] Free ISPs are Internet service providers that provide service free of charge. Many free ISPs display advertisements while the user is connected; like commercial television, in a sense they are selling the user's attention to the advertiser. Other free ISPs, sometimes called freenets, are run on a nonprofit basis, usually with volunteer staff. Wireless ISP[edit] A wireless internet service provider (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 MHz, 2.4 GHz, 4.9, 5.2, 5.4, 5.7, and 5.8 GHz bands or licensed frequencies such as 2.5 GHz (EBS/BRS), 3.65 GHz (NN) and in the UHF band (including the MMDS frequency band) and LMDS.[ (3:11 - 9:20) Click on the Link for online Video for HTML : https://youtu.be/mP1Tt3sSyMU Video by Edupedia World (www.edupediaworld.com), Online Education, All Right Reserved.
