Gekko
Reading: [getsukou]
Field:
Multimedia > game > game machine for home > Gekko |
It is loaded onto [nintendogemukiyubu], the microprocessor of the IBM corporation make.
Being something which PowerPC 750 in for the game machine customizes, in order to be able to process the especially 3D data efficiently, improvement is added.
As a concrete revised point, single precision floating point arithmetic two simultaneously it can process, the secondary cache 256KB is loaded on the processor core, compressing the data where precision is not required, you can list those where you use memory efficiently.
Gekko is produced with 0.18 millimicron process, the operational clock has become 485MHz. In addition, PowerPC architecture has the merit that the electric power consumption of Gekko calls approximately 5W electric power consumption is little originally, it is held down to low level.

GEO
Reading: GE o
Full spelling: Geostationary Earth Orbit
Field:
Multimedia > broadcast > GEO |
Geosynchronous orbit of satellite. Because with thing of the circular track of the equator sky of altitude 35786km, the revolution period which around the earth the circumference is done completely it is the same time as 1 lap of rotation of the earth, from the ground always identical direction, the satellite exists in position of angle of elevation. The geostationary satellite is suited for the communication of bulk of the terrestial station which is locked, is used for satellite television broadcasting, data communication and audio telephone call etc. The weather satellite of the broadcast communications satellite of BS and CS etc and “the sunflower” etc is the geostationary satellite.

Geography XML <G-XML>
Field:
Expression of information > markup language > XML > Geography XML
IT and society > GPS/GIS > Geography XML
|
XML based markup language and protocol in order describes the spatial data which with the geographical information system (GIS) and the like is utilized and various contents which include the information of position, between the computers this to utilize circulation mutually. The Japan Information Processing Development Center Database Promotion Center being center, being something which decides specification, Geography XML 2.0 has become the Japan Industrial Standard (JIS) as JIS X 7199. In addition, as for Geography XML 3.1 GML and the specification which are the standard due to OGC of the economic organization are standardized.
It reaches the point where & it can accumulating transmit with Geography XML, spatial data such as map topographical data and various information contents etc which had geographical attribute, with standardized description method. Description method of the basic data has quoted the standard of GML where specification was standardized, but with Geography XML handles geographical information with such as Internet releasing the service which, to the plural software and service cooperating, the case where it operates communication protocol etc in regard it is stipulated. Because of this, superposing various informations to the map data, it reaches the point where it can make the processing where it indicated, it processed combining the data of the type which differs, constructed new service combining the contents and the service which are open on the net and/or it said easy.

| . It can peruse the photograph which photographed French territory of the French mainland and the foreign country from the satellite, with various reduced scale. The road map and the usual map, color classifying difference in elevation to in addition to, you can peruse the relief map which it indicates in the same way with various reduced scale. There is Google Earth which, Google offers as the service which resembles to geoPORTAIL, but if it limits to the French domestic satellite photograph, it is assumed that geoPORTAIL is clearer than Google Earth. As for President French Chirac, Google and Yahoo! The speech which we assume that the technical predominance of France and European each country verges to crisis, vis-a-vis the technology which such as MSN enterprise of the American sphere has, is done, it has announced that repayment exemption conditional financing is done for engineering development of the French German which opposes to these search engines search engine.

GE-PON
Reading: The GE tweet o n, [jipon] and [jiipon]
Full spelling: Gigabit Ethernet-Passive Optical Network
Field:
Communication service > broadband > optical fiber > GE-PON
|
The technology which actualizes the transmission speed of 1Gbps with the public network which uses the optical fiber. It is observed as the technology which improves the transmission speed of Internet connection service by the optical fiber substantially.
Until recently, Gigabit Ethernet which is the technology which is used with LAN is applied, the frame of Ethernet sending and receiving is done that way from central telephone exchange to home. Because with former optical access technology ATM is used for this section, was restricted to 100Mbps speed with such as the overhead which depends on conversion. Even in Japan the optical fiber connection service of 1Gbps broadband major each company with GE-PON is announced.
