Computer network architecture refers to the underlying design and structure of a computer network. It encompasses the layout, components, protocols, and technologies that are used to establish and maintain connectivity between multiple devices within a network.
At its core, computer network architecture is concerned with how data is transmitted, received, and processed across the network. This includes the physical components such as routers, switches, and cables, as well as the logical components like protocols and software applications.
The architecture can be classified into different types depending on the scale and purpose of the network. Local Area Networks (LANs) are designed for small geographic areas like homes or offices, while Wide Area Networks (WANs) connect multiple LANs and cover larger areas like cities or countries. Other types of networks include Metropolitan Area Networks (MANs), which cover an entire city or region, and Storage Area Networks (SANs), which are used for high-speed data storage and retrieval.
Computer network architecture also encompasses the design decisions related to security, scalability, and performance. This includes the choice of protocols, network topologies, and hardware components that can handle the demands of the network and ensure efficient and reliable communication between devices.
Overall, computer network architecture is the blueprint for how devices connect and communicate within a network, providing a framework for data transmission and enabling the sharing of resources and information across multiple devices.
