What is client-server architecture?

Interaction model where clients (e.g., browsers or mobile applications) request resources or services from a server, and the server provides them.

Main components:

• Client: Initiates requests, sends them to the server, and processes the received responses.
• Server: Waits for requests from clients, processes them, accesses data (e.g., database), and sends responses back to the client.

Examples of interaction:

1. User enters a website address in the browser (client).
2. Browser sends an HTTP request to the web server.
3. Web server processes the request, retrieves data from the database.
4. Web server generates an HTML page and sends it to the browser.
5. Browser displays the page to the user.

Advantages:

• Centralized management of data and resources on the server.
• Ease of scaling the server-side part.
• Separation of responsibilities between client and server.
• Ability to use different types of clients to access the same resources.

Disadvantages:

• Client dependence on the server.
• Possible server overload with a large number of requests.
• Need for a network connection for interaction.
