# Cyber Security for Beginners ~ 1.5 Role of Servers and Clients

The client-server model serves as a fundamental architectural framework in the field of IT and cybersecurity. In this model, two distinct entities interact: the client and the server.

**The Client** is typically a user's device, such as a computer or smartphone, that requests services or resources from a server. It acts as the interface allowing users to access information or perform operations.

**The Server** is a powerful machine that hosts, manages, and provides resources to clients. Servers are tasked with processing requests from multiple clients, delivering data they require, and ensuring smooth communication.

Understanding this division of roles is crucial, as it helps clarify how services are rendered and accessed over networks, such as the internet.
