1) Database
Joomla 3. x supports the following databases –
- MySQL
- SQL Server
- PostgreSQL
Generally, I used the MYSQL database for the installation of Joomla and it is working fine on that.
2) Joomla Framework
Joomla is based on MVC (model–view–controller ) Architecture and was developed in PHP programming language. This is the second topmost cms that come after WordPress. This web application framework can be used free of the CMS which allows you to build powerful online applications.
3) Extensions(Components, Modules, Plugins)
Joomla supports 3 types of extension Components, Modules, and Plugins.
Components
A component may be a sort of Joomla! extension. Components are the most functional units of Joomla!; they will be working as mini-applications. a simple way would be that Joomla! is that the OS and therefore the components are desktop applications. Content, that is made by a component is typically shown inside the center of the most content region of a layout (depending on the template settings).
Modules
Modules are lightweight and flexible extensions used for page content rendering. These modules are like “boxes” arranged around a component on a typical page. A very well-known example is the login module modules are connected to a menu thing, so ready to select to appear or cover up for illustration and the login module depends on the menu thing the client is as of now on.
Plugins
A plugin is a type of Joomla extension. within Joomla, plugin developers create functions that are related to trigger events. Joomla provides a group of core plugin events, but for an extension, we will fire (custom) events. When any specific event occurs, all plugin functions of the sort related to the event are executed during a sequence. this can be frequently a solid way of expanding the use of Joomla. It also offers extension developers how to permit other extensions to reply to their actions, making extensions extensible.

4) Templates
Front-end Templates
Front-end templates change the layout of your site looks to users. Most of the templates you apply or install are going to be Front-end Templates. Out of the box Joomla 3. x ships with two front-end templates, protostar (which is about as default), and Beez3. for easy sites, these out-of-the-box templates could also be appropriate, but a majority of Joomla users will prefer to install a 3rd party template to suit the aim of their site. A site can use multiple templates assigned to different menu items, but most beginners will just use one template for his or her entire site.
Back-end Templates
Back-end Templates are much rarer than Frontend Templates. you’ll probably never got to change your Back-end Template. Administrator Templates allow you to vary the way the administrator interface looks. Joomla 3. x ships with two rear templates, isis (which is about as default), and Hathor. The Hathor(built-in) template was created for accessibility, which should be applicable for those with color vision deficiency who require high contrast colors, or those utilizing screen reader devices or keyboard navigation.
5) Web Browser
A web browser is just a platform where we can see the output of the website. So web pages need a browser to display their output.
