Abstract: With the development of information technology and all the benefits which they extol in our lives come new problems. They need to be solved. One of these problems is to reduce the trend of Moore's Law, that is, the number of transistors has ceased to double every 24 months. Authors of this article offer versions of the solution of the arisen problem.
Keywords: information technology, Moore's Law, computing technology, microprocessor performance.

Summary: The computational model of additional errors, which occur from interaction of intense shock N-wave with inertial positioning devices of hypersonic aircraft was built. Angles of coincidence for the industrial design of the angular velocity sensor were fitted. A comparative analysis of the experimental data for seminatural conditions for the two cases (gyroscope ON, gyroscope OFF) was made. Conclusions about the possibility of use of the results were made.
Key words: N-wave, hypersonic aircraft, caustic zone, wave coincidence, float gyroscope.
Summary. In article parametres of influence of a site of a broadband network of user's access, and also quality indicators are considered by transfer on networks of the traffic of a various kind.
Аnnotation: The industrial robots using positioning the stops to reduce dynamic loads and reduce the dynamic error component used special damping devices. However, when changing the speeds of the masses and working organs (PO) in a wide range such devices require the adjustment of its parameters. The use of shock absorbers as elastic thrusts allows for the maximum speed of the PO and the reduction of dynamic loads at the time of hitting the fence.
Necessary characteristics depreciation quality can be obtained as a result of the construction of systems with variable structure, which are due to discontinuous control essentially nonlinear systems. Operation of the system variable structure provides instant removal and restoration, using the logic switching elements, relations between its individual links and the use of local mineral properties of these units [1]. In the energy aspect of the amortization of the system of variable structure are more advantageous than the active vibration isolation system as well as the energy they expended only on the parameters of control.
Keywords: control, pneumatic shock absorber movement.
