<<CMS 6%
A Content Management System (CMS) is a software system for organizing and facilitating collaborative creation of documents and publishing websites. A web content management system is often used to manage and control a large, dynamic collection of web material ( HTML documents and their associated images). A CMS facilitates document editing. It offers standard visual templates that can be automatically applied to new and existing content, creating one central place to change that look across a group of content on a site. Most CMS software include WYSIWYG editing tools allowing non-technical individuals to create and edit content. Active CMS solutions usually receive regular updates that include new feature sets and keep the system up to current web standards. The most commons free CMS are : Joomla! , Spip , Drupal , BitFlux , eZPublish , Plume , Typo3 , Postnuke ...
<<DNS 6%
Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.168.0.154. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned. The BIND DNS server is a very popular and free DNS server. When setting up a new web site one needs to register a DNS name at a DNS registry. One site can have serveral DNS names, also called server aliases.
<<High-availability cluster 3%
HA clusters are often used for critical databases, file sharing on a network, business applications, and customer services such as electronic commerce websites.
<<LAMP 3%
The acronym LAMP refers to a solution stack of software programs, commonly open-source programs, used together to run dynamic Web sites on servers. The original combination of these technologies is as follows: Linux , referring to the operating system ; Apache , the Web server ; MySQL , the database management system (or database server) ; PHP , the programming language. More recently, the P has come to refer frequently to Perl or Python as alternate programming languages. At all2all, standard LAMP systems also feature PostgreSQL as alternative database.
<<Podcast 3%
A podcast is a digital media file , or a series of such files, that is distributed over the Internet. In other words, a podcast is a collection of audio or video files residing at a unique web feed address. People can "subscribe" to this feed by submitting the feed address to an aggregator. When new "episodes" become available in the podcast they will be automatically downloaded to the users computer. Though podcasters' web sites may also offer direct download or streaming of their content, a podcast is distinguished from other digital media formats by its ability to be syndicated, subscribed to, and downloaded automatically, using an aggregator or feed reader capable of reading feed formats such as RSS (Really Simple Syndication) or Atom.
<<RSS feed 6%
RSS (Really Simple Syndication) is a family of web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a "feed," "web feed," or "channel," contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that's easier than checking them manually. RSS content can be read using software called a "feed reader" or an "aggregator." The user subscribes to a feed by entering the feed's link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user's subscribed feeds regularly for new content, downloading any updates that it finds.
<<Ruby on Rails 6%
Ruby on Rails is a web application framework, released in 2004, that aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Often shortened to Rails, or RoR, Ruby On Rails is an open source project written in the Ruby programming language and applications using the Rails framework are developed using the Model-View-Controller design pattern. The official web site is : http://www.rubyonrails.org/
<<SSL 3%
Secure Sockets Layer (SSL) and its successor, Transport Layer Security (TLS), are cryptographic protocols which provide secure communications on the Internet for such things as web browsing, e-mail, Internet faxing, instant messaging and other data transfers. There are slight differences between SSL 3.0 and TLS 1.0, but the protocol remains substantially the same. The term "SSL" as used here applies to both protocols unless clarified by context.SSL provides endpoint authentication and communications privacy over the Internet using cryptography. Typically, only the server is authenticated while the client remains unauthenticated; this means that the end user can be sure with whom they are communicating. The next level of security—in which both ends of the "conversation" are sure with whom they are communicating—is known as mutual authentication. Mutual authentication requires public key infrastructure (PKI) deployment to clients. SSL is used by numerous e-commerce web sites to secure payments over the Internet. This application also requires to obtain a certificat issued by a certificate authority .
<<Version control 3%
Revision control, also known as version control and source control (and an aspect of software configuration management), is the management of changes to documents, computer programs, large web sites, and other collections of information. Changes are usually identified by a number or letter code, termed the "revision number", "revision level", or simply "revision". For example, an initial set of files is "revision 1". When the first change is made, the resulting set is "revision 2", and so on. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and with some types of files, merged. Read more
<<Virtualmin 3%
Virtualmin is a Webmin module for managing multiple virtual hosts through a single interface on Unix -like systems. It supports the creation and management of Apache virtual hosts, BIND DNS domains, MySQL databases, and mailboxes and aliases with Sendmail or Postfix. Together with the existing Webmin and Usermin modules, Virtualmin offers a total autonomy to administrators of web sites , virtual or dedicated servers who can access all control features and automatically set up user's limits appropriately. These server administrators can also manage the mailboxes and mail aliases via a web interface that is part of the module.
<<Webmail 3%
A Webmail refer to the implementation of an e-mail client as a Web application that allows users to access their e-mail through a Web browser, as an alternative to using a desktop-based client such as Microsoft Outlook or Mozilla Thunderbird or Eudora. A webmail client is usually offered by an email service to allow its users to access their mail stored on the service's server from any computer (e.g. in a cybercafé). The word Webmail refer to an email service that is offered through a website, sometimes the only way to users to access their email, and sometimes in addition other methods of making the email available to the user, such as the POP3 or IMAP4 protocols.
<<Web Site 28%
A web site is a collection of web pages, images, videos and other digital assets that is hosted on a web server, usually accessible via the Internet. A web page is a document, typically written in HTML , that is almost always accessible via HTTP, a protocol that transfers information from the web server to display in the user's web browser. All publicly accessible websites are seen collectively as constituting the World Wide Web . The pages of websites can usually be accessed from a common root URL called the homepage, and usually reside on the same physical server. The URLs of the pages organize them into a hierarchy, although the hyperlinks between them control how the reader perceives the overall structure and how the traffic flows between the different parts of the sites. The web pages can be uploaded via File Transfer Protocol (FTP) to the web server that allows individuals and organizations to provide their own web sites accessible via Internet. One can set up his own web site by himself (with a little understanding of html) or call upon a web-designer to do the job.
