Local Loopback
Set wire ties (son of copper) or between the radio station and the subscriber switch subscribers to which it belongs. The local loop is thus part of a network operator that provides direct access to the subscriber.
Bps
Acronym bit per second. Unit of measurement used to express the amount of information conveyed by a communication channel at a time t. 1 kbps equals 1024 bps. 1 Mbps is 1024 kbps. As 1octet equivalent to 8 bits, 1 kb / s is 8 kbps.
Browser hijackers
Literally "hijackers browser"These small programs alter the browser settings and involve the receipt of very intrusive popups and particularly tendentious.
Noise
A noise is a random phenomenon. We later discovered two types of noise especially important, obeying Gaussian or Poisson statistics. Do not confuse a signal parasiteOr observational bias, with a noise. The bias that affects the signal has properties that distinguish it quite a noise. A very common way is an offset, ie a shift of the signal due to the fact that the zero level of physical signal and its zero Translation into an electrical signal does not coincide.
The distinction between noise and spurious signal can be complex. We can take the example of the dark current of a detector, which is superimposed on the observed flux. Its average value is perfectly measurable (both photoelectron pixel per second), which shows that this is a signal, but certainly with parasitic properties of a signal. The real component of noise fluctuations on the dark current.
