An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
1. Physical layer. The Open Systems Interconnection ( OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." [ 2] In the OSI reference model, the communications between systems are split ...
Delay-tolerant networking. Delay-tolerant networking ( DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space.
The history of the Internet has its origin in the efforts of scientists and engineers to build and interconnect computer networks.The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and ...
Network topology is the arrangement of the elements ( links, nodes, etc.) of a communication network. [ 1][ 2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [ 3] industrial fieldbusses and computer networks .
Network architecture. Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used. In telecommunication, the specification of a network ...
In computing, network virtualization is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization.
In computer networking, Point-to-Point Protocol ( PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [ 1] It can provide loop detection, authentication, transmission encryption, [ 2] and data compression . PPP is used over many types of physical networks ...
