Squeak

Field:
Programming > language > Squeak

One of the software development environment which designates Smalltalk of programming language as the base. It can do programming graphical on the picture making use of the mouse and the like, the fact that we offer the environment which is called “Squeak eToys”, even with the programming not yet experience person and the child we can do programming simply is major feature. The example which is utilized in education actual place low as the teaching aid for grade it is many.

With Squeak eToys, Morph ([mohu]) with you draw the graphic object which is called on GUI making use of the paint tool, you can set the operation of that Morph by the fact that the panel where order and the condition etc for Morph are written is combined. For example you draw picture such as car as Morph, by the fact that operation is set combining the order panel of revolution and movement etc, you can draw up the kind of animation which the car is running. Furthermore, by the fact that the panel of the contact decision and the like of Morph is combined, it can produce also higher-level game and the like simply. It is possible also to do the description with Smalltalk language other than the panel directly.

The communication of HTTP and the like relay cash the proxy server software which is done. It corresponds to also FTP and SSL and the like. We are open, anyone freely it can procure & can utilize as the open source software. The user is restricted due to user identification, setting is done with the Web browser, there is also a function which zone control of the circuit is done. Operating on client side, it can also use as reverse proxy

One kind of RAM. Being something which uses the flip-flop circuit as a storage cell, it does not need the operation for memory retention. It operates to high speed, but it has the fault that the circuit becomes complicated and is difficult to increase built-upness.

sRGB standard RGB

Field:
Imaging > expression of color > sRGB

IEC (International Electrotechnical Commission) decided in 1998 October, international standard standard of the color space. With the difference of equipment such as difference and display and printer of the type of personal computer, as intended, form in order to reproduce color is decided

The color space, with the range of the color which it can indicate & can print and thing of the expression system, from the fact that the color which can be expressed with the quality of the equipment differs, there is various systems. As for sRGB in the color space which is decided in order to guarantee the reproducibility of color between the environment which differs, color expression of CRT display the standard which is decided in the base.

For example, if the digital camera and the personal computer and display, the printer entirely corresponds to sRGB, when it displays indicates the photograph which is taken when the photograph which becomes in the color which is different, indicates is printed it can avoid the trouble that it becomes the color which is different.

SRP Security roll-up package

Full spelling: Security Roll-up Package
Field:
Windows > Security > SRP

The update program which is offered vis-a-vis, the leading product of the Microsoft corporation, such as Windows gathers and summarizes the security patch. 2 month period with the goal of it has meant release to be done periodically in regard to Windows.

Besides the fact that contents of the security patch which is not included in up-to-date Service Pack are almost included everything, several correction of the simple bug which it is not related to security there are times when it is included. There is also a security hole which is corresponding with only the security roll-up package.

Operation verification is located to the single-engine patch and the center of Service Pack. In other words, up-to-date Service Pack is installed, next the up-to-date security roll-up package is applied and, the procedure that the single-engine patch is applied (it limits when it is not included in up-to-date Service Pack), even then only concerning the security hole which is not corresponding is placed in mind.

SSD Flash memory drive

Alias:
flash memory drive
Field:
Storage > SSD

The drive device which uses flash memory as a memory medium. Hard disk drive (HDD) with the same connected interface standard (ATA standard) we have, we are observed as the high-speed storage which is substituted to HDD.

As for SSD like HDD because it does not have the disk, the case of reading and writing of the data, the reader (the head) the time when it makes move on the disk (the seek time) and, the intended data on the disk the time when it turns (the search time) does not exist to head position. Because of this reading and writing of the data it has accelerated dramatically in comparison with HDD. In addition like HDD using the motor, because it is not necessary to turn the disk, also electric power consumption has decreased substantially. Furthermore, because the disk drive part which it is easy to break with impact does not exist, you can say that it is high chip resistance in comparison with HDD.

Field:
Microprocessor > x86/Intel > Intel > SSE

The multimedia expansion instruction set which is loaded after the Pentium III it is the microprocessor of the Intel corporation. Formally release before being done, it was called KNI. It undertakes MMX succession which is adopted for Pentium and Pentium II. Is shown power even such as drawing of the 3D graphics which is made poor MMX to which the order which is used frequently in function and the multimedia processing which execute plural floating-point several operations simultaneously is added, makes the acceleration of integer arithmetic proud. Furthermore, 3DNow which is loaded onto Athlon XP of the AMD corporation! The order which is suitable to SSE even in Professional instruction set is included.
