plz thanks
Answer:
Network architecture refers to how computers are organized in a system and how tasks are allocated between these computers. Two of the most widely used types of network architecture are peer-to-peer and client/server. Client/server architecture is also called 'tiered' because it uses multiple levels.It includes hardware components used for communication, cabling and device types, network layout and topologies, physical and wireless connections, implemented areas and future plans. In addition, the software rules and protocols also constitute to the network architecture.A robust network architecture will facilitate system level functionality as well as robustness, extensibility, and evolvability in the face of changes in software and hardware components, application functions, implementation of security measurements, and external environments.A Layered architecture provides a clean-cut interface so that minimum information is shared among different layers. It also ensures that the implementation of one layer can be easily replaced by another implementation. A set of layers and protocols is known as network architecture.
