The physical network topology can be directly represented in a network diagram, as it is simply the physical graph represented by the diagrams, with network nodes as vertices and connections as undirected or direct edges (depending on the type of connection). [3] The logical network topology can be inferred from the network diagram if details ...
Also shown in this example (shaded in yellow) is the network's connection to the Internet via fixed-line means. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, [1] [2] [3] and has its network equipment and interconnects locally managed. LANs facilitate ...
Examples of aggregation at layer 1 (physical layer) include power line (e.g. IEEE 1901) and wireless (e.g. IEEE 802.11) network devices that combine multiple frequency bands. OSI layer 2 ( data link layer , e.g. Ethernet frame in LANs or multi-link PPP in WANs, Ethernet MAC address ) aggregation typically occurs across switch ports, which can ...
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1 ]
A personal area network (PAN) is a computer network used for communication among computers and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and video game consoles.
The core network provides high-speed, highly redundant forwarding services to move packets between distribution-layer devices in different regions of the network. Core switches and routers are usually the most powerful, in terms of raw forwarding power, in the enterprise; core network devices manage the highest-speed connections, such as 10 ...
Home Network Administration Protocol (HNAP) is a proprietary network protocol invented [1] by Pure Networks, Inc. and acquired by Cisco Systems which allows identification, configuration, and management of network devices. HNAP is based on SOAP. [2] Starting in January 2010, vulnerabilities were discovered in multiple D-Link network devices ...
SiLA 2 addresses control and data interfaces between devices and process management, LIMS and Enterprise Systems. It is built to connect systems in a laboratory, such as laboratory information management systems , electronic lab notebooks , chromatography software and laboratory devices such as balances, pipettors and various other analytical ...
