Network service model refers to the framework that defines how network services are provided to users and applications. It specifies the characteristics and capabilities of the services offered by the network, such as reliability, security, and performance guarantees. Common network service models include connection-oriented (e.g., TCP) and connectionless (e.g., UDP) protocols, which dictate how data is transmitted, acknowledged, and managed across the network. These models ensure consistent and predictable behavior in communication between devices and systems.
Network models encompass conceptual frameworks that describe the structure and functionality of computer networks. The OSI (Open Systems Interconnection) model and the TCP/IP (Transmission Control Protocol/Internet Protocol) model are prominent examples. The OSI model divides network communication into seven layers, each responsible for specific functions such as data encapsulation, routing, and application interaction. TCP/IP, on the other hand, combines multiple protocols into a streamlined set for Internet communication, emphasizing simplicity and interoperability across diverse network environments.
The model of networking system refers to the architectural design and configuration of a network infrastructure. It encompasses the physical components (e.g., routers, switches, cables) and logical configurations (e.g., addressing schemes, routing protocols) that define how devices connect and communicate within the network. Networking systems can range from simple local area networks (LANs) to complex wide area networks (WANs) and cloud-based infrastructures. Effective design and management of these systems ensure efficient data transmission, scalability, and resilience to meet organizational needs and support critical business operations.
