Network layer
The network layer, also known as Layer 3 or the internetwork layer, is the OSI model layer that routes packets between hosts across multiple networks, done by IP in TCP/IP.
Network model
The network model, also called the network data model, is a database model formalized by CODASYL in 1971 in which programs navigate records linked by pointers.
Network North
Network North is a UK Department for Transport policy paper published in October 2023, announcing by Rishi Sunak the reallocation of £36 billion from canceled HS2 phases to smaller transport projects.
Network operating system
A network operating system (NOS) is an operating system for routers and switches, or, in an older sense, software that manages shared files, printers, and logins across a network.
Network operations center
A network operations center (NOC), also called a Network Control Center, is a centralized location where staff monitor and manage a network's health around the clock.
Network packet
A network packet, also called a data packet, is a formatted unit of data carried over a packet-switched network, with headers carrying control information followed by the payload.
Network Rail
Network Rail Limited, established by the Department for Transport in 2002 to acquire Railtrack's network, owns and operates Great Britain's railway infrastructure, including track, signaling, bridges, tunnels and stations.
Network reconnaissance
Network reconnaissance is the systematic gathering of information about a target network, including its hosts, services, and vulnerabilities, and is an early phase of the cyber kill chain.
Network representation learning
Network representation learning maps each node of a graph to a dense low-dimensional vector, or embedding, preserving network structure for tasks like node classification and link prediction.
Network RTK
Network RTK (NRTK) is a real-time satellite positioning technique in which a network of GNSS reference stations streams corrections, extending centimeter accuracy to about 100 km.
Network security
Network security, also called Netsec or LAN security, is the use of firewalls, VPNs, and intrusion detection systems to control traffic and protect computer networks.
Network segmentation
Network segmentation is the practice of dividing a computer network into separate subnetworks, so that approved security policy controls traffic between them and limits attackers' lateral movement.
Network slicing
Network slicing is a 5G architecture technique that runs multiple independent virtual networks on a single shared physical mobile network, each tailored to a service's performance and security needs.
Network socket
A network socket, also called an Internet socket, is an endpoint for communication between two programs over a network, identified by an IP address and port.
Network switch
A network switch, also known as an Ethernet switch, is a networking device that connects devices on a local area network and forwards Ethernet frames by MAC address.
Network switching subsystem
The network switching subsystem, also known as the GSM core network, is the part of a telephone network comprising exchanges and signaling that sets up calls.
Network synthesis
Network synthesis is the branch of circuit theory that derives a physical electrical network, both its topology and element values, from a prescribed input-output relationship, the inverse of network analysis.
Network throughput
Network throughput is the amount of payload data a network actually delivers per unit of time, and it is affected by latency, loss, and protocol behavior.
Network topology
Network topology is the physical and logical structure of a network, describing how nodes such as switches, routers, and endpoints are interconnected and how data flows among them.
Network-attached storage
Network-attached storage (NAS) is a storage device that connects to a network, giving multiple users and devices centralized file access as if the files were local.
Network-coded cooperation
Network-coded cooperation is a wireless communication technique in which relays combine the packets of several users, often by bitwise XOR, so one relayed transmission serves multiple receivers at once.
Networking hardware
Networking hardware, also called network equipment, is the class of physical devices such as switches, routers, and wireless access points that connect, forward, and secure network traffic.
Netzsch
Netzsch is a German family-owned machinery and instrumentation group founded in 1873 in Selb, Bavaria, known for its NEMO pumps and for equipment used in lithium-ion battery manufacturing.
Neuba II Gas Pipeline
The Neuba II Gas Pipeline is a natural gas pipeline in Argentina running from the Neuquén Basin to Buenos Aires, built in 1988 and operated by TGS.
Neue Klasse (BMW)
The Neue Klasse was a range of BMW sedans and coupés produced from 1962 to 1972, beginning with the 1500 and rescuing BMW from near-bankruptcy.
Neugart
Neugart is a German family-owned manufacturer of precision planetary gearboxes for robotics, machine tools, and medical equipment, founded in 1928 and headquartered in Kippenheim, Germany.
Neura Robotics
Neura Robotics GmbH is a German robotics company founded by David Reger in 2019 in Metzingen, known for cognitive robots including the humanoid robot 4NE1.
Neural architecture search
Neural architecture search (NAS) is a machine learning method that automatically discovers neural network architectures for a task, using a search space, a search strategy, and performance estimation.
Neural audio codecs
A neural audio codec is a learned compression system that turns audio into discrete codes with an encoder, quantizer, and decoder, serving as the substrate for audio language models.
Neural belief propagation
Neural belief propagation, also called weighted belief propagation (WBP), is a family of neural decoders for error-correcting codes, introduced by Nachmani, Be'ery, and Burshtein in 2016.
