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 ...
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.
A high-level overview of the software-defined networking architecture. The following list defines and explains the SDN architectural components: [32] SDN application SDN applications are programs that communicate their network requirements and desired network behavior to the SDN controller via a northbound interface (NBI). In addition, they may ...
Wi-Fi provides wireless access to the Internet via local computer networks. Hotspots providing such access include Wi-Fi cafés, where users need to bring their own wireless devices, such as a laptop or PDA. These services may be free to all, free to customers only, or fee-based. Grassroots efforts have led to wireless community networks.
Network utilities are software utilities designed to analyze and configure various aspects of computer networks. The majority of them originated on Unix systems, but several later ports to other operating systems exist. The most common tools (found on most operating systems) include:
System software is a generic term referring to the computer programs used to start and run computer systems including diverse application software and networks. Computer programming tools, such as compilers and linkers, are used to translate and combine computer program source code and libraries into executables, which are programs that fall ...
CYCLADES – a French research network created in the early 1970s that pioneered the concept of internetworking by making the hosts responsible for the reliable delivery of data on a packet-switched network, rather than this being a service of the network itself. Computer Science Network (CSNET) – a computer network created in the United ...
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
