What is tunnelling effect in STM?
The tunneling effect in STM (scanning tunneling microscope) refers to the phenomenon where electrons tunnel through a vacuum barrier between a sharp tip and a sample surface. This allows for the measurement of electron density and surface topography at the atomic scale. The STM measures the tunneling current resulting from this effect to create high-resolution images of surfaces.
What does Quantum tunneling refer to?
Quantum tunneling is a physics phenomenon within the area of quantum mechanics. Basically it refers to when a particle can tunnel through a barrier that it could not surmount in classic physics.
What is Latin for Strongest?
Strongest = validissimus There are several possible choices for strongest -the context is all-important.
What are applications of uncertainty principle?
Uncertainty Principle can be used to give a drawback to Bohr's Model of an atom. In that atomic model Bohr said that electrons exist in certain well defined energy levels, to give a contradiction to this statement uncertainty principle may be used.
Advantages of tunneling electron microscope over conventional microscopes?
Tunneling electron microscopes offer higher resolution imaging capabilities due to their ability to achieve atomic-scale resolution. They also provide information about the electronic structure of materials by measuring the tunneling current between the sample and the tip. Additionally, tunneling electron microscopes can operate in a vacuum environment, allowing for imaging of delicate or sensitive samples without interference from air molecules.
What is the strongest tunneling protocol?
L2TP over IPSec
A tunneling protocol is used to facilitate?
You use a tunneling protocol when you want to preserve confidentiality in information that is being sent across a network. This way listeners cannot understand the information.
What protocols can a windows xp computer use to establish a virtual private network cnnection to a remote access server?
Point-to-point tunneling protocol (PPTP) and Layer Two tunneling protocol (l2tp) with internet security protocol (ip/sec)
What is cisco's vpn protocol that relies on on IPSec for all its security needs?
Layer 2 Tunneling Protocol (L2TP)
What is the difference between 802.1q and ISL?
ISL IS A CISCO PROPRIETARY TUNNELING PROTOCOL, BUT 802.1 q IS A OPEN STANDARD PROTOCOL
The PPTP VPN tunneling protocol is based on technology developed by Cisco?
PPTP tunneling was developed by Microsoft.
Which security protocol is used in vpns and is a combination of microsofts point-to-point tunneling protocol and ciscos layer 2 fowarding?
L2tp
Which tunneling protocol will allow you to provide the highest level of security when implementing a vpn?
L2tp
What tunneling protocol will allow you to provide the highest level of security when implementing a vpn?
IPSec with encapsulating encryption
What does the acronym PPTP stand for?
PPTP is term used in computer security that is a protocol of implementing virtual private networks. The acronym PPTP stands for Point to Point Tunneling Protocol.
Which tunneling protocal should be used?
Secure Socket Tunneling Protocol (SSTP) is a new VPN protocol that uses port 443, which is also used by Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS). SSTP is used to transport Point-to-Point Protocol (PPP) traffic through an SSL channel. Currently it is only available on newer operating systems such as Windows Vista and Windows Server 2008.
In which layer of OSI model does GTP protocol stand?
There are actually two different GTP protocols. GTP (Go Text Protocol) is basically an application layer protocol, although the definition is a bit fuzzy. GTP (GPRS Tunneling Protocol) is a transport layer protocol that is used in conjunction with another transport layer protocol (TCP or UDP).
