Internet Protocol This article is about the IP network protocol only. For Internet architecture or other protocols, see Internet protocol suite. The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. Historically, IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974; the other being the connection-oriented Transmission Control Protocol (TCP). The first major version of IP, Internet Protocol Version 4 (IPv4), is the dominant protocol of the Internet. Function[edit] The Internet Protocol is responsible for addressing hosts and for routing datagrams (packets) from a source host to a destination host across one or more IP networks.

Introduction to RSS(Rich Summary Site) Recently, there has been an unprecedented caution regarding data privacy. With infamous leaks and instances of phishing and spamming all around, no one wants to put their personal information out there without restraint, in fear of being the next unfortunate target. This makes staying posted with favored content on the massive expanse of the World Wide Web a daunting task. It seems like its time to grab onto the steering wheels. What is RSS? RSS stands for Rich Site Summary or Really Simple Syndication. To set up RSS for a website an XML file has to be created known as the RSS document or RSS Feed.Below is a sample RSS document. Explanation of the code : First comes the XML tag, its version and encoding scheme.The following line marks the beginning of the RSS tag with its version in use. .The next few lines show the channel tag, which marks the beginning of the RSS Feed. Once the XML is ready and validated, it is uploaded to the server.
S-T: Http Request/Response Anatomy Introduction to Web Web consist of billion of clients and server connected through wires and wireless networks. The web clients makes request to web server. The web server receives the request, finds the resources and return response to the client. Web Application A web site is a collection of static files such as HTML pages, images, graphics etc. HTTP is a protocol that clients and server uses on the web to communicate.It is similar to other internet protocol such as SMTP(Simple Mail Transfer Protocol) and FTP(File Transfer Protocol) but there is one fundamental difference.HTTP is a stateless protocol i.e HTTP supports only one request per connection.This means that with HTTP the clients connects to the server to send one request and then disconnects. HTTP method HTTP request can be made using a variety of methods, but the ones you will use most often are Get and Post. HTTP Method and Descriptions Difference between GET and POST request Anatomy of an HTTP GET request
PHP Scripting language created in 1994 PHP is a general-purpose scripting language geared towards web development.[8] It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995.[9][10] The PHP reference implementation is now produced by the PHP Group.[11] PHP was originally an abbreviation of Personal Home Page,[12][13] but it now stands for the recursive initialism PHP: Hypertext Preprocessor.[14] The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. The PHP language has evolved without a written formal specification or standard, with the original implementation acting as the de facto standard that other implementations aimed to follow. History[edit] Early history[edit] PHP development began in 1993[9] when Rasmus Lerdorf wrote several Common Gateway Interface (CGI) programs in C,[20][21] which he used to maintain his personal homepage. <!

HTTP: The Protocol Every Web Developer Must Know - Part 2 In my previous article, we covered some of HTTP's basics, such as the URL scheme, status codes and request/response headers. With that as our foundation, we will look at the finer aspects of HTTP, like connection handling, authentication and HTTP caching. These topics are fairly extensive, but we'll cover the most important bits. A connection must be established between the client and server before they can communicate with each other, and HTTP uses the reliable TCP transport protocol to make this connection. HTTPS is a secure version of HTTP, inserting an additional layer between HTTP and TCP called TLS or SSL (Transport Layer Security or Secure Sockets Layer, respectively). An HTTP connection is identified by <source-IP, source-port> and <destination-IP, destination-port>. resolve IP address from host name via DNSestablish a connection with the serversend a requestwait for a responseclose connection The server is responsible for always responding with the correct headers and responses.
File Transfer Protocol FTP is built on a client-server architecture and uses separate control and data connections between the client and the server.[1] FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that hides (encrypts) the username and password, and encrypts the content, FTP is often secured with SSL/TLS ("FTPS"). SSH File Transfer Protocol ("SFTP") is sometimes also used instead, but is technologically different. History[edit] The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC 114 on 16 April 1971. Until 1980, FTP ran on NCP, the predecessor of TCP/IP.[2] The protocol was later replaced by a TCP/IP version, RFC 765 (June 1980) and RFC 959 (October 1985), the current specification.

Create interactive presentations with Genially, free and online | Genially Interactive slides contain clickable hotspots, links, buttons, and animations that are activated at the touch of a button. Instead of reading or watching passively, your audience can actively interact with the content. Genially’s interaction presentation software allows you to combine text, photos, video clips, audio and other content in one deck. If you’re a teacher, you can share multiple materials in one single learning resource. An interactive slide deck is more user-friendly than a Microsoft PowerPoint presentation or Google Slides document. The other benefit of interactive content is increased engagement. The best way to make slides clickable is to use Genially’s free interactive presentation program. Choose from the library of hotspot buttons and icons to show people what to click on. You’ve got a deadline looming and you’re staring at the screen with a blank presentation. Because Genially is a cloud based presentation software, you can simply share the link to your slides.
Cascading Style Sheets CSS is designed primarily to enable the separation of document content from document presentation, including elements such as the layout, colors, and fonts.[1] This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. It can also be used to allow the web page to display differently depending on the screen size or device on which it is being viewed. CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. Syntax[edit] Selector[edit] Use[edit]

Web Services Description Language The Web Services Description Language (WSDL) is an XML-based interface description language that is used for describing the functionality offered by a web service. The acronym is also used for any specific WSDL description of a web service (also referred to as a WSDL file), which provides a machine-readable description of how the service can be called, what parameters it expects, and what data structures it returns. It thus serves a purpose that corresponds roughly to that of a method signature in a programming language. The current version of WSDL is WSDL 2.0. The meaning of the acronym has changed from version 1.1 where the D stood for Definition. Description[edit] Representation of concepts defined by WSDL 1.1 and WSDL 2.0 documents. The WSDL describes services as collections of network endpoints, or ports. Example WSDL file[edit] <? History[edit] WSDL 1.0 (Sept. 2000) was developed by IBM, Microsoft, and Ariba to describe Web Services for their SOAP toolkit. See also[edit] References[edit]
