The geographical information system (GIS) and the like with XML based markup language in order to describe the spatial data which is utilized and various contents which include the information of position. OGC of the economic organization (Open Geospatial Consortium) has decided specification. GML 3.1 is standardized as ISO 19136 International Organization for Standardization (ISO) with. In addition, with the same version also G-XML of the Japanese standard specification was standardized.

It reaches the point where & it can accumulating transmit with GML, spatial data such as map topographical data and various information contents etc which had geographical attribute, with standardized description method. 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 and/or it said easy.

GMPLS

Reading: Gee m tweet l s
Full spelling: Generalized Multi-Protocol Label Switching
Field:
LAN > VPN > GMPLS
Network technology > network control > GMPLS

Technology in order the routing to do the signal with respect to optical network. With MPLS adding the label to the packet, it appointed routing route, but with GMPLS the wave length of the light information deciding routing route on the basis of preparing the control private IP channel the processing that while it is the light information the routing it does the actual data, is done. Converting the light information to the electric information the case of the routing, as for doing the routing because the overhead is large, while it designates the data as the light information the decision of GMPLS which can do the routing is advanced. Furthermore, it does not decide the specification of GMPLS yet, but at the manufacturer development of the product which already mounts GMPLS is advanced.

GMR head

Reading: Gee m earl head
Full spelling: Giant Magneto Resistive Head
Alias:
Enormous reluctance effect
Field:
Storage > hard disk > GMR head

The reader of the hard disk which applies the enormous reluctance effect (the head). According to the fluctuation of the external magnetic field electric resistance changes the element where is used in the GMR head, the MR head which uses the same principle by using the element of the cobalt base which is sensitive to magnetism compared to sensitivity of 3 times or more is actualized.

GMSK

Reading: Gee m s k
Full spelling: Gaussian filtered Minimum Shift Keying
Field:
Network technology > GMSK

At one of the modulation techniques which convert digital value to the analog signal, frequency modulation (FSK) those which are improved. It is developed in Europe and it is used even in modulation technique of the portable telephone system GSM which is used standard in the world.

With FSK value is allotted to frequency of the carrier, information is transmitted with the combination of the wave of plural frequencies, but there is a fault that the frequency zone which becomes necessary becomes large. You hold down the spread of the spectrum with GMSK the gauss filter ([gaushianhuiruta]) with combining the filter which is said, efficiently have tried to be able to do modulation and demodulation with narrow zone.
