What role does a server play in a network infrastructure and what tasks does it solve?

A server in a network infrastructure acts as a central node that provides various services and resources to client devices (clients). The main tasks of a server:

• Processing client requests and providing responses (for example, a web server handles HTTP requests).
• Storing and managing data (for example, databases).
• Managing access and security (authentication, authorization).
• Facilitating resource sharing (files, printers).
• Executing business logic of applications.

Thus, the server ensures centralized management and coordination of interactions between clients and network resources.
