101. What hardware does Drupal.org run on?

People often wonder what kind of hardware drupal.org runs on. Throughout the project history this has been a tough question. For a while it was a server in a random office building. That server eventually died and required a fund-raising effort to replace (the funds were raised in 24 hours!).

The critical infrastructure is all configured to share the load and be redundant. For example, db1 and db2 are configured to be master-slave most of the time to provide for better performance and allow the slave to be promoted to master if the master fails.

100. Drupal and Working with JavaScript

Drupal provides methods for implementing JavaScript. Using these methods will help to keep your code clean and to ensure compatibility with the way other modules implement JavaScript.

A couple of simple principles guide Drupal's JavaScript approach:

·     All pages should be perfectly functional without scripts. JavaScript provides alternatives or supplements - not replacements - for standard elements.

·  

       No JavaScript is hard-coded into pages. Rather, actions are attached dynamically to page elements--and only if the needed JavaScript support is present.

99. Why does Drupal need a database? What databases are supported?

Drupal stores its information - the individual pages, the registered users, and so on - in the database. The database forms the back-end for your Drupal site. At this time, Drupal supports MySQL (or an equivalent such as MariaDB), PostgreSQL, and in Drupal 7, SQLite.

74. What are Entity types in drupal ?

An entity type is a useful abstraction to group together fields. Entity types are used to store and display data, which can be nodes (content), comments, taxonomy terms, user profiles, or something custom developed.

Read more about Entities in the Entity API documentation.

71. What is triage ?

A new bug or issue is assigned a priority based on its severity, frequency, risk and other predetermined factors, borrowed from medical term triage.

68. What is teaser in drupal ?

A short introductory sentence or paragraph about a piece of content that informs readers about the subject of the content. By default, the first paragraph or two of the content is used (there is a setting for how much), usually with a link to the complete node.

67. What is render array in drupal ?

Render arrays are the basic building blocks of Drupal content. In Drupal 7, render arrays provide a structured way to programmatically alter content before it is displayed. Further details can be read on the Render Arrays documentation page.

63. What is DrupalCon and Druplicon ?

DrupalCon 

The semi-annual conference dedicated to gathering Drupal practitioners. It alternates between a North American location and a European location.

Druplicon

The Drupal mascot. It is a neologism formed from joining the words “Drupal” and “icon”.

57. What are breadcrumbs ?

The set of links, usually near the top of the page, that shows the path you followed to locate the current page. For example, it might show Home > Drupal > Current Events > News Articles, meaning that you started at the home page, clicked on “Drupal” in the menu, then selected “Current Events” in the sub-menu, and finally selected, “News Articles.” The term breadcrumbs is borrowed from Hansel and Gretel, who left crumbs of bread along their path so they could find their way back out of the forest.

54. What is drupal panels ?

The drupal panels is a module in drupal which allows a drupal website administrator to create customized layouts for multiple uses. At its core it is a drag and drop content manager that lets you visually design a layout and place content within that layout. Integration with other systems allows you to create nodes that use this, landing pages that use this, and even override system pages such as taxonomy and the node page so that you can customize the layout of your site with very fine grained permissions.

13. What is a Module in drupal ?

13. What is a Module in drupal ?
A module is software (code) that extends Drupal features and/or functionality. Core modules are those included with the main download of Drupal, and you can turn on their functionality without installing additional software. Contributed modules are downloaded from the Modules download section of drupal.org, and installed within your Drupal installation. You can also create your own modules; this requires a thorough understanding of Drupal, PHP programming, and Drupal's module API.
