Definition von tunneling%26%23160 im Englisch Englisch wörterbuch

tunneling
the quantum mechanical passing of a particle through an energy barrier
tunneling
the practice of exploring tunnel
tunneling
Present participle of tunnel
tunneling
the act of burrowing a tunnel
tunneling
In quantum mechanics, the passing of a particle through a seemingly impenetrable barrier without a cause that is explainable by classical physics
tunneling
An important concept in the design of many kinds of networks: taking some protocol-family's ability to move packets from user to user, or to open virtual-circuits between users, and use this as if it were a data-link protocol to run another protocol family's upper layers (or even the same protocol family's upper layers) Examples: running TCP/IP over AppleTalk instead of something like Ethernet; running AppleTalk over DECNet instead of something like Localtalk or Ethernet
tunneling
A classical particle or system could not penetrate regions in which its energy would be negative, that is, barrier regions in which the °potential energy is greater than the system energy In the real world, however, a °wave function of significant amplitude may extend into and beyond such a region If the wave function extends into another region of positive energy, the barrier is crossed with some probability; this process is termed tunneling (since the barrier is penetrated rather than climbed)
tunneling
A VPN can be created by using "tunneling " Tunneling is a technology that allows a network transport protocol to carry information for other protocols within its own packets For example, IPX data packets can be encapsulated in IP packets for transport across the Internet, which isn't normally possible The packets are delivered unmodified to a remote device that has been setup to handle them The packets maybe secured using data encryption, authentication or integrity functions
tunneling
The act of transmitting data formed with one protocol within the structures of another protocol, allowing the data to be sent in the prevailing format of a network (usually IP) Examples of tunneling used in VPNs include L2TP and Microsoft’s PPTP
tunneling
When incomplete bonding causes releasing from the substrate and long areas of the flooring form tunnel-like deformities, usually over underlayment joints Tunnels are normally caused by movement of the underlayment joints from moisture growth and are sometimes combined with product growth
tunneling
Also called a 'run' When the cigar burns faster on one side than it does the other Turn the cigar as you smoke to prevent it from happening
tunneling
A technology used by VPNs to encapsulate, encrypt, and transmit data over the Internet infrastructure, enabling business partners to exchange information in a secured, private manner between organizational firewalls
tunneling
A technique of encapsulating one protocol within another, such as IPX with IP In the context of security, it refers to encrypting IP within IP so that the traffic may be routed securely
tunneling
Tunneling is a way to channel communications between a server and a remote user Secure methods of tunneling involve encryption
tunneling
Drilling or trenching for the placement of underground passages for utility lines, subways, trains, roads, or other uses Tunnels can cause a diminution in value if the market perceives that they may not be structurally sound or may fail in the event of a seismic event, such as an earthquake
tunneling
A method for circumventing a firewall by hiding a message that would be rejected by the firewall inside a second, acceptable message
tunneling
Architecture providing the services necessary to implement any standard point-to-point data encapsulation scheme
tunneling
Two similar networks connected through a different type of network can logically communicate through the heterogeneous network using multi protocol routers
tunneling
v. or barrier penetration In physics, the passage of a particle through a seemingly impassable energy barrier. Though a particle's energy may be too low to surmount a barrier in classical physics, the particle may still cross the barrier as a consequence of its quantum-mechanical wave properties. An important application of this phenomenon is in the operation of the scanning tunneling microscope
tunneling
A quantum-mechanical effect causing particles to pass through an energy barrier without having the energy normally associated with that barrier In the context of transistors, electron tunneling has been observed across opens in metal lines, causing logic gates to function at low frequencies but fail at high frequencies
scanning tunneling microscope
A device used to form an image of the surface of a conductor or semiconductor with atomic resolution
scanning tunneling microscopes
plural form of scanning tunneling microscope
Point to Point Tunneling Protocol
protocol that enables the transfer of data packets of TCP/IP through a foreign network that is not based on these protocols (by marking the packet with an address suited to the foreign network)
scanning tunneling microscope
A microscope that scans the surface of a sample with a beam of electrons, causing a narrow channel of tunneling electrons to flow between the sample and the beam, and producing three-dimensional images of atomic topography and structure
