clienteservidor

Cliente-servidor is a distributed application structure that partitions tasks or workloads between providers of a resource or service, called servers, and service requesters, called clients. This model is fundamental to many computing and networking paradigms.

In a client-server system, the client initiates communication requests. The server, which typically has more processing power and resources, listens for these requests and responds to them. The server's role is to manage and provide access to shared resources such as databases, files, or printers. Clients, on the other hand, are responsible for the user interface and presenting the information received from the server.

This architecture offers several advantages. It promotes resource sharing, allowing multiple clients to access the same data or services. It also enhances security, as sensitive data can be stored and managed centrally on the server. Furthermore, it simplifies maintenance and updates, as changes can be implemented on the server without affecting individual clients.

Examples of client-server systems are ubiquitous. Web browsing is a classic example, where a web browser (client) requests a webpage from a web server. Email systems also operate on this model, with email clients connecting to mail servers to send and receive messages. Database management systems frequently employ a client-server architecture for accessing and manipulating data.
