A description of data formats & procedures used for communication between nodes.

Master plan to support the development of advanced data communications networks and the standards for those networks.

The organization of computer and communications systems which supports communication and cooperation between them.

The philosophy and organizational concept for enabling communications between equipment at multiple locations; detailed specifications outlining the processors, terminals and transmission media, protocols and software to be used to accomplish accurate communications.

the complete set of hardware, software and cabling standards for a local area network design

A description of how communication occurs within a specific type of network.

The design of a communications system including hardware, software, access methods and protocols.

The communication equipment, protocols and transmission links that constitute a network, and the methods by which they are arranged.

The network architecture is the hardware configuration of a network, including the layout of the cabling and the design of the network. Source: TechSoup.org

A set of specifications that defines every aspect of a data network's communication system, including but not limited to the types of user interfaces employed, the networking protocols used, and the structure and types of network cabling that may be used.

n. The underlying structure of a computer network, including hardware, functional layers, interfaces, and protocols, used to establish communication and ensure the reliable transfer of information. Network architectures are designed to provide both philosophical and physical standards for the complexities of establishing communications links and transferring information without conflict. Various network architectures exist, including the internationally accepted seven-layer ISO Open Systems Interconnection (OSI) model and IBM's Systems Network Architecture (SNA). See also ISO/OSI model, SNA.

In computing, network architecture is the design of a computer network.

specification of design principles (including data formats and procedures) for creating a network configuration of data processors

The set of principles, including the organization of functions and the description of data formats and procedures, that governs the design and implementation of a user- application network.

Set of design principles defining the protocol, functions and logical components of a network and how they should perform.

The specification of a network's functions and its parts, together with the ways in which the network is organized; specifies the layers of different functions in the network, ranging from data transmission at the lowest levels to user applications at the highest levels.
