Electronic key certificate and certificate lapse list (CRL) standard specification. ITU (the International Telecommunication Union) advised in 1988.

As for those where presently it is used widely with X.509v3 which is advised in 1996, this providing the extended territory in the certificate, is designed in such a way that the publisher of the certificate can add individual information.

As for X.509v3 as for the electronic certificate version number of the open key and serial number of the certificate, open key information and the certification bureau information which issues the certificate, term of validity of the certificate, information of the active person who is proven, it consists of the item such as the extended territory. Is possible the fact that the information such as E-mail address and IP address etc is used to the extended territory. … The continuation is read

As for X.509v3 it is utilized under various circumstances as an expedient of encoding and the privacy protection on Internet such as SSL and TLS etc.

The instruction set which was loaded onto the microprocessor of the AMD corporation, in order to be able to correspond to the data and memory address of 64 bit width, expands x86 order. It is installed in the Opteron series and the Athlon 64 series etc.

As for x86 instruction set, with the instruction set which originally, is adopted for the microprocessor of the 80x86 series of the Intel corporation, as for present specification it is something of 32 bit correspondence which is introduced from i386. The Intel corporation when the microprocessor of 64 bits is designed, does again to define instruction set from one, it is joint with the Hewlett-Packard corporation and it is completely new, (is not) “IA-64” architecture of compatibility was developed until recently.

As for this because it is the completely new design, the existing software is operated, it is necessary to convert 32 bit order to 64 bit order, it is said that amount of the processing which depends on conversion, 32 bit processor compared to operating speed is inferior. … The continuation is read

Vis-a-vis this, the AMD corporation which is the competitive processor manufacturer of the Intel corporation developed individual x86-64 architecture as the approach which can utilize existing software property effectively. As for this, while x86 instruction set taking over, being something which does the expansion to 64 bits, to execute at the speed where either the software of 32 bits is not inferior until recently it is possible the software which is expanded to 64 bits to high speed.

With x86-64, the data and the like of 64 bit width can be handled, “Long Mode” and, the data of 32 bit width is handled, operational mode of 2 types “of Legacy Mode” is prepared. When 64 bit extended function is used, at OS level mode of the microprocessor is modified in Long Mode. Legacy Mode is former x86 instruction set and full compatible mode.

When the microprocessor is operational with Long Mode, also it is possible for the microprocessor to execute because it reaches the point where both of 64 bit cord/code and 32 bit cord/code can be executed, calling 32 bit based library from the program which is written in 64 bit base.

The name, “x86-64” was modified to “AMD64” attendant upon the formal release of on-board processor. After that, also the Intel corporation AMD64 interchangeable 64 bit function “Extension Memory 64 Technology” (EM64T) has announced offer.

Series name of the microprocessor which the Intel corporation developed. Mainly it is used almost monopolizes this market as CPU of the personal computer. Because as for the processor of this series release it is done in the order of 8086?8088?80186?80286?i386?i486, it is called in this name. Recently the AMD corporation and the Cyrix corporation and the IBM corporation etc have produced the interchangeable processor.

Arranging the element in the window, as in one kind of markup language in order to appoint decoration and layout etc, described the Web page with HTML, can XAML describe the user interface of the application software in markup language. Combining with ASP.NET and the like, it is possible also to utilize in picture drawing of Web application.

XAML has designated Microsoft .NET Framework 3.0 as the basis, the picture is formed combining the display element which is defined with the same framework. From simple letter and the picture, input element such as text box and button, the effect such as figure drawing, complicated vector graphics such as line and circle and 3D object, and those deformation and animation can be utilized. … The continuation is read

Can be worthy of the input element of specification also to tie with variable and/or (data binding), to define the mutual relationship of object, to set event processing according to the operation of the user.
