Databases: Databases are used to store and manage data. Common database systems include MySQL, PostgreSQL, MongoDB, and Microsoft SQL Server.

Web Servers: Web servers like Apache, Nginx, and IIS handle HTTP requests from clients and serve the appropriate web pages and resources.

Frameworks: Back-end frameworks such as Django (Python), Spring (Java), Laravel (PHP), and Express.js (Node.js) provide a structured way to build robust and scalable web applications.

Developing server-side logic and APIs (Application Programming Interfaces).

Managing databases and ensuring data integrity.

Handling user authentication and authorization.

Ensuring server security and performance.

Increased versatility and problem-solving abilities.

Ability to work independently on projects.

Better understanding of the entire web development process.

• Challenges:

Requires a broad range of skills and knowledge.
