A dynamic website is one that displays different content to users based on various factors such as their preferences, interactions, and data input. Unlike static websites that display the same information to every visitor, dynamic websites can change and customize content in real-time. These sites often use databases and server-side scripting languages to create interactive and personalized experiences. Here's an overview of dynamic websites:

Features and Characteristics:

1. Content Management System (CMS):

   • Dynamic websites often use a CMS like WordPress, Joomla, Drupal, etc., to manage and update content easily.
   • Content can be added, edited, and removed without needing to modify the website's code.

2. Database Integration:
