Network functions virtualization (NFV) [1] is a network architecture concept that leverages IT virtualization technologies to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create and deliver communication services. NFV relies upon traditional server- virtualization techniques ...
Network virtualization. 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.
Virtual organization. A virtual organization is a temporary or permanent collection of geographically dispersed individuals, groups, organizational units, or entire organizations that depend on electronic linking in order to complete the production process ( working definition [1] ). Virtual organizations do not represent a firm’s attribute ...
Virtual private network. A virtual private network ( VPN) is a mechanism for creating a secure connection between a computing device and a computer network, or between two networks, using an insecure communication medium such as the public Internet.
Virtual private network. A virtual private network (VPN) is an overlay network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. The data link layer protocols of the virtual network are said to be tunneled through the larger network.
v. t. e. A virtual local area network ( VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer ( OSI layer 2 ). [2] [3] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network. VLANs work by applying tags to network frames ...
v. t. e. In machine learning, a neural network (also artificial neural network or neural net, abbreviated ANN or NN) is a model inspired by the structure and function of biological neural networks in animal brains. [1] [2] An ANN consists of connected units or nodes called artificial neurons, which loosely model the neurons in a brain.
The Internet (or internet) [a] is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) [b] to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of ...
