From the fact that two large major enterprises of the streaming technology, Microsoft corporation and the RealNetworks corporation do not participate, the voice which extent of the actual result doubt apparent is done has come out.

Specification “ISMA 1.0” in order the streaming to transmit the image voice data which was compressed to 2001 October, with MPEG-4 was announced. This specification has “Profile 0” for the low usage terminal and, the profile of 2 types, such as portable telephone “Profile 1” for the advanced terminal of PC and the like and PDA.

The English standard association (BSI) “BS7799” is decided in 1999 as the standard of ISMS, following 2000, it is practice norm, it was standardized internationally “BS7799 Part 1” International Organization for Standardization (ISO) with as “ISO/IEC 17799”. In the country the guideline which parallels to the same standard it is standardized as “JIS X 5080” in 2002.

Information security management system of enterprise (ISMS), is international standard standard, to the fact that it is conformed “ISO/IEC 17799” is recognized, foundation Japan Information Processing Development Center (JIPDEC) the appraisal system.

ISMS organization of enterprise and the like managed information appropriately, could decide the international standard, ISO/IEC 17799 with inclusive framework straw raincoat thing in order to protect secrecy, International Organization for Standardization (ISO) with in 2000. In the country the guideline which parallels to the same standard it is standardized as “JIS X 5080” in 2002.

According to the definition of JIPDEC, ISMS “other than technical measure every of individual problem, deciding necessary security level as a management of organization, with the risk appraisal of the self, the resource distributing with plan, using the system” is. Namely, not only security measure of the computer system, the case where information is handled basic policy (security policy) and, it included to execution use of concrete plan and the plan which are based on that and the second look at policy plan every of fixed period, total it points to the thing of risk management system.

ISM band 2.4GHz band

Alias:
2.4GHz bandwidth
Field:
LAN > Wireless LAN > ISM band

If in the radio wave band of 2.4GHz neighborhood, in Japan, it is output below 10mW, being license unnecessary, in order to be able to utilize, the territory where it is open. With the band which is used for the equipment for industrial scientific medical science, taking these initials, the “ISM band” (Industry Science Medical band) also it is called.

If many of the band of the radio are allotted by the one for communication broadcast and there is no license it is not possible to utilize. But, because many electronic equipment such as the microwave oven generate and/or have utilized the electromagnetic wave of feeble output, the 2.4GHz band is open as the zone which can use the equipment such as that freely.

Recently, the wireless LAN and various radio Internet technologies have been utilized making use of this band. The wireless LAN of the DSSS system which conforms to IEEE 802.11b as the communication standard which uses the 2.4GHz band, there is Bluetooth, HomeRF and a FWA system etc of part.

Field:
Expression of information > letter/font > character code > ISO 2022

One of the standard regarding the treatment of the character code which is standardized by ISO. In Japan it has become the JIS standard, “JIS X 0202”. From 7 bits the various letter data are expressed at 8 bits.

With ISO-2022 many character sets are defined, the same cord/code to the letter where plural is different overlapping, are allotted. Actually when letter is handled, it presents, it utilizes which character set first, during that character set it selects the letter which corresponds to the cord/code. When the letter which is not the character set becomes necessary, it changes to the character set which includes that dynamically.

This approach, ISO-10646 standard and generally known Unicode is contrast. With Unicode, in order to express many letters, the cord/code space is largely taken making use of many bit numbers such as 16 bits and 32 bits, the technique that is adopted in that all letters are included.
