klientservermønsteret

The client-server model is a fundamental computing architecture where tasks or workloads are partitioned between providers of a resource or service, called servers, and service requesters, called clients. This pattern distributes processing tasks across multiple computers, each having a specific role. The server is typically a powerful machine that stores and manages shared resources or data, such as files, databases, or web pages. It passively waits for requests from clients.

Clients are usually end-user devices like personal computers, smartphones, or workstations. They initiate communication by sending requests to the server for specific services or data. Once the server receives a request, it processes it and sends a response back to the client. This response can be the requested data, a confirmation of an action, or an error message.

This model offers several advantages, including centralization of resources, improved security through controlled access, and scalability by adding more clients or upgrading the server. Common examples of client-server applications include web browsing (where your browser is the client and the website's server hosts the content), email systems, and online gaming. The interaction between client and server is defined by a communication protocol, which ensures that both parties understand how to exchange information.
