What device or component acts as a client in a web application architecture?

In web application architecture, the client is a device or component that initiates requests to the server and displays the received information to the user. Most often, this is a web browser on a computer, smartphone, or tablet.

The client is responsible for:

• Sending HTTP requests to the server.
• Receiving and processing responses (HTML, JSON, CSS, JavaScript).
• Rendering the user interface.
• Interacting with the user.

For example, when you open a website in a browser, the browser is the client that requests pages from the web server and displays them.
