The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks. A DHCP server enables computers to request IP addresses and networking parameters automatically from the Internet service provider (ISP), reducing the need for a network administrator or a user to manually assign IP addresses to all network devices. In the absence of a DHCP server, a computer or other device on the network needs to be manually assigned an IP address, or to assign itself an APIPA address, which will not enable it to communicate outside its local subnet.
Electronic mail is a method of exchanging messages ("mail") between people using electronic devices. Invented by Ray Tomlinson, email first entered limited use in the 1960s and by the mid-1970s had taken the form now recognized as email. Email operates across computer networks, which today is primarily the Internet. Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface for as long as it takes to send or receive messages.
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.
The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.
A Uniform Resource Identifier (URI) is a string of characters that unambiguously identifies a particular resource. To guarantee uniformity, all URIs follow a predefined set of syntax rules, but also maintain extensibility through a separately defined hierarchical naming scheme.
In computing, Internet Key Exchange is the protocol used to set up a security association (SA) in the IPsec protocol suite. IKE builds upon the Oakley protocol and ISAKMP. IKE uses X.509 certificates for authentication ‒ either pre-shared or distributed using DNS ‒ and a Diffie–Hellman key exchange to set up a shared session secret from which cryptographic keys are derived. In addition, a security policy for every peer which will connect must be manually maintained.
The name Atom applies to a pair of related Web standards. The Atom Syndication Format is an XML language used for web feeds, while the Atom Publishing Protocol is a simple HTTP-based protocol for creating and updating web resources.
Web standards are the formal, non-proprietary standards and other technical specifications that define and describe aspects of the World Wide Web. In recent years, the term has been more frequently associated with the trend of endorsing a set of standardized best practices for building web sites, and a philosophy of web design and development that includes those methods.
Timothy William Bray is a Canadian software developer and entrepreneur and one of the co-authors of the original XML specification. He has worked for Amazon Web Services since December 2014 and previously for Google, Sun Microsystems, the Digital Equipment Corporation (DEC) and several start-ups.
Ian Avrum Goldberg is a cryptographer and cypherpunk. He is best known for breaking Netscape's implementation of SSL, and for his role as chief scientist of Radialpoint, a Canadian software company. Goldberg is currently a professor at the David R. Cheriton School of Computer Science, within the University of Waterloo. He was formerly Tor Project board of directors chairman, and is one of the designers of off the record messaging.
about is an internal URI scheme implemented in various Web browsers to reveal internal state and built-in functions. It is an IANA officially registered scheme, and is standardized.
The Hyper Text Coffee Pot Control Protocol (HTCPCP) is a facetious communication protocol for controlling, monitoring, and diagnosing coffee pots. It is specified in RFC 2324, published on 1 April 1998 as an April Fools' Day RFC, as part of an April Fools prank. An extension, HTCPCP-TEA, was published as RFC 7168 on 1 April 2014 to support brewing teas, which is also an April Fools' Day RFC.
Elizabeth Castro, sometimes known as Liz Castro, is an American author and translator best known for her books aimed to educate the reader on particular aspects of website development, such as HTML and Perl. From 1987 to 1993 Castro lived in Barcelona and managed the translation of computer programs. In 1993 she moved back to the United States to write books about using the internet and World Wide Web.
Ed Krol is the former network manager at the National Center for Supercomputing Applications and the former assistant director of Campus Information Technologies and Educational Services (CITES) at the University of Illinois at Urbana–Champaign. He is also the author of The Hitchhiker's Guide to the Internet and The Whole Internet .
Web syndication technologies were preceded by metadata standards such as the Meta Content Framework (MCF) and the Resource Description Framework (RDF), as well as by 'push' specifications such as Channel Definition Format (CDF). Early web syndication standards included Information and Content Exchange (ICE) and RSS. More recent specifications include Atom and GData.
An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable, transition technologies are designed to permit hosts on either network type to communicate with any other host.
A Request for Comments (RFC), in the context of Internet governance, is a type of publication from the Internet Engineering Task Force (IETF) and the Internet Society (ISOC), usually describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems.
SMTP Authentication, often abbreviated SMTP AUTH, is an extension of the Simple Mail Transfer Protocol (SMTP) whereby a client may log in using any authentication mechanism supported by the server. It is mainly used by submission servers, where authentication is mandatory.
Stuart H. Harris is an English author of books and articles about the internet, and internet consultant, now living in California, United States. He is a computer professional, an expert on IRC and has written a book on the subject, IRC Survival Guide: Talk to the World with Internet Relay Chat, published in 1995 by Addison-Wesley, ISBN 978-0-201-41000-6. He is also a performer with three years experience as a semi-professional actor on the festival circuit, two years as a professional in London and in provincial repertory theatre, and further experience as a director in television. The aforementioned extensive cross-disciplinary experience motivated Harris to explore the potential of creating a Shakespeare performance online; namely, a contemporary production of Shakespeare's Hamlet known as Hamnet.
A Uniform Resource Locator (URL), colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), although many people use the two terms interchangeably. Thus http://www.example.com is a URL, while www.example.com is not.</ref> URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
