Nätverksarkitekturer

Nätverksarkitekturer describes the overall design and organization of a computer network. It defines how various components like computers, servers, routers, and switches are interconnected and how they communicate with each other. A fundamental aspect of network architecture is the layered model, most commonly represented by the OSI model or the TCP/IP model. These models break down network communication into distinct layers, each with specific functions, promoting modularity and standardization.

Common network architectures include client-server, peer-to-peer, and hybrid models. In a client-server architecture, dedicated servers provide resources and services to client devices. Peer-to-peer networks allow devices to share resources directly without a central server. Hybrid architectures combine elements of both.

The choice of network architecture depends on factors such as the size of the network, the required performance, security needs, and budget. Different architectures have varying levels of complexity, scalability, and cost. Understanding network architectures is crucial for designing, implementing, and troubleshooting efficient and reliable networks.
