What are the main differences between the server-side and client-side parts of a web application?

Main differences between the server-side and client-side parts of a web application:

• Location and execution of code:

  • The client-side (frontend) runs in the user's browser.
  • The server-side (backend) operates on the server.

• Functionality:

  • The client handles interface display, user interaction, and event processing.
  • The server processes business logic, database operations, authentication, storage, and data processing.

• Technologies:

  • The client-side is usually implemented using HTML, CSS, JavaScript.
  • The server-side can be written in Node.js, Python, Java, PHP, and other languages.

• Security:

  • The server controls access to data and protects business logic.
  • The client-side is less secure as the code is accessible to the user.

• Interaction:

  • The client sends requests to the server (e.g., via HTTP), and the server responds with data or operation results.

Thus, the server and client perform different roles but together ensure the operation of the web application.
