The American major semiconductor manufacturer which is established to 1993. As for head office the California state Santa Clara. Developing & producing the graphic tip/chip and chip set etc for the personal computer. As for origin of the company name with Spanish “envy and envy, you are jealous and” and so on it means are thought from “envidia”.

For the personal computer the graphic tip/chip Riva series hit on the nineties latter half, reached the point where the section of the leading manufacturer of this field is occupied. Presently we sell the graphic tip/chip of the GeForce series, the Canadian ATI Technologies corporation of the rival unfold extreme competition. Having produced & selling the video card to which many manufacturers adopt the same tip/chip. The function of GeForce was installed, also the integrated chip set nForce series for the AMD corporation make microprocessor is famous

NVOD Near video on demand

Reading: N buoy o D
Full spelling: Near Video ON Demand
Field:
Multimedia > animated picture > NVOD

Using the plural channels, the broadcast system where the viewer is can select viewing start time by broadcasting the same program at fixed interval. False video on demand.

Video on demand (VOD: Video ON Demand) the system selects the program which the viewer would like to see, the broadcasting station following to the indication of the viewer, transmits program. As for this kind of system in order the existing broadcast system to designate the technology which differs completely as the basis, construction to be difficult cost is high.

Vis-a-vis this, those where it is it tries to be able to select viewing time freely making use of the point where the cable television and the like can use many channels, by letting flow the same program at fixed interval are the NVOD system. For example, using channel 10, if it shifts start time each 10 minutes, it can select viewing time at width of 100 parts.

NX bit

Reading: N x bit
Field:
Microprocessor > x86/Intel > AMD > NX bit
Security > network > NX bit

The memory protect function which the microprocessor of the AMD corporation has. The fact that the program executes illegitimately is prevented. The NX bit is utilized, the software (OS) correspondence on the side being necessary, Windows XP Service Pack of the Microsoft corporation 2 (XP SP2) later and the like is corresponding.

There is “buffer overflow” in the technique which is utilized the occasion where the virus and the cracker take over the computer. Sending the program which has malice in the territory where this was done to overflow, rather than the program having supposed, being accustomed to sending many data, the memory territory, overflowed it is the technique which it makes execute.

The cracker and the like sending the program in the system which corresponds to the NX bit by acquiring the sign that “here is the data area”, in the bit of specification of memory territory, OS inspecting that, it is possible to try not to be able to execute.

Field:
Enterprise information system > computer system > large-scale system > n tear system

In the client server system, separating processing of the client and the server into plural classes, by the fact that it arranges, to a certain class the system which it tries to be able to correspond softly even the occasion where the necessity to add modification occurs.

At one time, as for the business system there was many a thing which is constituted from 2 classes of the client and the server. When in 2 hierarchical systems processing because business is actualized (business logic) we are described by all client sides, modification occurs in business logic, it was necessary to do again to arrange the software of client side entirely.

In 3 hierarchical systems, “presentation layer” (user interface), “application layer” (business logic), “data heirarchy” (the database) to divide the whole system into 3 classes, to leave only the user interface part on client side, then it mounts on server side. The client accepts the operation from the user, does only the fact that the processing result from application layer is indicated.

n type semiconductor

Reading: As for the n abnormal play it is how you want
Field:
Semiconductor > basis technology > n type semiconductor

Electric charge is carried, in the semiconductor where the free electron is used “the carrier”. Silicon of high purity (silicon: Si) It is formed in, the arsenic of 5 value elements which one of the numbers of valence electrons are more than silicon (As) and the like extremely very small amount by mixing.

Inside the n type semiconductor, the electron which is left over not to be used in connection of the atom (the free electron) is born while crystallizing, electric current occurs due to the fact that this moves. This time, negative number (negative) the electron which has electric charge bears electric conduction, because it becomes “the carrier”, it is called the “n type semiconductor”.

Vis-a-vis this, the righteousness (positive) it has electric charge, “the positive hole” (the hole) the semiconductor which bears the role which conveys electric current is called the “p type semiconductor”. Semiconductor device such as diode and transistor is born by combining the n type semiconductor and the p type semiconductor.
