Drupal 7: Technology Stack 

Server 
A server is a computer which provides information or services to other computers on a network. 

Operating system 
The operating system is the software that runs the server. Unix, Linux, BSD, OS X and Windows are some examples. 

Database 
A database is a structured collection of records. Drupal uses a database to store most content and configuration settings for your site, some content such as media files are generally stored in the server's file system. Examples are MySQL and PostgreSQL. 

Web server 
The web server is the software component responsible for serving web pages. Examples are Apache and Microsoft IIS. 

PHP 
PHP is a programming language that allows web developers to create dynamic content that interacts with databases. To communicate with the databases the necessary database drivers (e.g., PDO_MYSQL) must be enabled. To process images certain libraries (e.g., GD) must be enabled as well. 

Drupal 
Drupal is a framework for building dynamic web sites offering a broad range of features and services including user administration, publishing workflow, discussion capabilities, news aggregation, metadata functionalities using controlled vocabularies and XML publishing for content sharing purposes. A Drupal installation is generally comprised of a mix of core and contributed modules. 

Add a Field to a Content Type in Drupal 7 

1. Navigate to the Content types page (Administer > Structure > Content types). 

2. In the table, locate the row that contains your content type and click the MANAGE FIELDS link. If you can't find the MANAGE FIELDS link, be sure to enable the Field UI module. 

3. In the Add new field section, enter a label for the field. 

4. In the Field name field, enter the machine name for the field. You can only use numbers, lower-case letters and the underscore character (_). The node that the machine name is automatically generated and it is not necessary that it be changed. 

5. In the field type list, select one of the field types. Note that more fields such as 'Date' and 'Location' can be added using Drupal modules. 

6. In the Widget field, select a widget. The options vary depending on the field type.
