TCP = Transmission Control Protocol / IP = Internet Protocol Web Design Workshop The World Wide Web But What is the Internet? http://img.bleepingcomputer.com/tutorials/dns.jpg IP = Internet Protocol ISP = Internet Service Provider DNS = Domain Name System Web Design Workshop The World Wide Web Brief History of The WWW: 1945 Memex Conceived 1945 ARPANET 1969 A Mathematical Theory of Communication 1948 TCP/IP Created 1972 Silicon Chip 1958 First Vast Computer Network Envisioned 1962 Packet Switching Invented 1964 Internet Named and Goes TCP/IP 1984 WWW Created 1989 Mosaic Browser Created 1993 Hypertext Invented 1965 Age of eCommerce Begins 1995 1995 • History of the Internet. 8:10 min http://www.youtube.com/watch?v=9hIQjrMHTv4 Copyright 2002, William F. Slater, III, Chicago, IL, USA Web Design Workshop Domain Name What is an URL? http://www.wccweb.claudiajacques.org • Uniform Resource Location – uniform way to locate a resource on the internet. • The URL specifies the address of a file and every file on the Internet has a unique address. • Web software, such as your browser, use the URL to retrieve a file from the computer on which it resides. Web Design Workshop Domain Name What is the Anatomy of an URL? http://www.wccweb.claudiajacques.org/images/test.jpg scheme://site address/path/filename & extension scheme – Also called resource type. Besides http = hypertext transport protocol, there are also ftp, File, mailto, news, telnet, Golpher. www = site address - Consists of host computer name wccweb = sub-domain claudiajacques = domain name org = domain type Images = path/ - directory & subdirectory test.jpg = filename and file extension Web Design Workshop Domain Name What is Domain Name Registrar? • Domain name registrar is an organization or commercial entity, accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) or by a national country code top-level domain (ccTLD) authority, to manage the reservation of Internet domain names in accordance with the guidelines of the designated domain name registries and offer such services to the public. • Until 1999, Network Solutions was the domain name registry for .com, . net and .org as well as the sole registrar. • An end-user cannot directly register a domain and manage their domain information with ICANN. http://en.wikipedia.org/wiki/Domain_name_registrar Web Design Workshop Domain Name Domain Name Registrar: • Only the designated registrar may modify or delete information about a domain name. • The competition that the SRS – Shared Registration System - created enables end users to choose from many registrars offering different services at varying prices. • It is not unusual for an end user to switch registrars which invokes a domain transfer process governed by specific domain name transfer policies. • Examples of Domain Name Registrars: GoDaddy, eNom, Tucows, Network Solutions, Names4ever, etc. http://www.domaintools.com/internet-statistics/registrar-stats-2007.php http://en.wikipedia.org/wiki/Domain_name_registrar Web Design Workshop Domain Name Domain Name Registry: • Is a database of all domain names registered in a top-level domain. • A registry operator, also called a Network Information Center (NIC), is the part of the Domain Name System (DNS) of the Internet that keeps the database of domain names, and generates the zone files which convert domain names to IP addresses. • Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the DNS tree by administrating the data in the root name servers. • Most Domain Name Registrars also offer Domain Name Registry. • The allocated and assigned domain names are made available by registries by use of the WHOIS system and via their domain name servers. Web Design Workshop Domain Name Confused? To develop a web site you need: 1.A Domain Name Registrar to register a domain name Domain Name Registry (Domain Hosting). 2.A Web Hosting Provider/Server Provider to manage the communication of your domain name with the net. 3.Now a days the process is transparent if you contract a web hosting provider. (Remember that most companies offer both services at once when you host your site with them.) GoDaddy, Hostmonster, BlueHost, Names4Ever, Network Solutions, are some of the reliable hosting providers. 4.Last, but not least: you need to design your site. Web Design Workshop Designing a Site?
