OMG which is the standardization group of object direction technology (Object Management Group) among UML technician qualifying examinations of 3 types which have been executed, the test whose degree of hardness is lowest. With UML technician qualifying examination, test of degree of hardness of 3 stages is prepared, but in order to receive the recognition after the 2nd stage, because it is necessary to have passed to the test of front stage, the examinee means to take an examination UML technician qualifying examination [huandamentaru] which first is 1st stage in beginning.

With UML technician qualifying examination [huandamentaru], the class figure, the activity figure, the sequence figure and the use case figure which among the figures where UML defines are the most basic one are included in the examination coverage. Terminology knowledge, and the basic concept etc of UML which are used with basic knowledge and understand the figure ability and UML regarding these figures are questioned.

UMPC <Ultra Mobile PC>

Reading: U m tweet the sea
Full spelling: Ultra-Mobiel PC
Field:
Mobile > personal computer > UMPC

The Microsoft corporation announced details in 2006 March, the standard of microminiature PC. It is categorized to the center of Mobile equipment and the notebook PC such as PDA, and portable telephone with the function which is equal to the notebook PC while being small-sized, it makes standard of the product which is superior in Mobile characteristic. As for development cord/code name “Origami” (folded paper).

As for size approximately width 20cm being strongly, as for weight center below and PDA and the notebook PC 900g. Pentium M and Celeron M, it loads VIA C7-MOS and the like in CPU, it corresponds to Ethernet, wireless LAN and Bluetooth with the hard disk drive 30 - 60GB, as a communication standard. To load the touch panel internal organs liquid crystal display of 7 inches or less, as for resolution above 800x480 pixel.

UMTS

Field:
Portable telephone > 3G > UMTS

The 3rd generation (3G) portable communication system of Europe. European usually of communication method of IMT-2000 conformity, as for maximum transmission speed 2Mbps. In developmental shape of the GSM standard which presently is used, it is possible even in Japan to select from both systems of W-CDMA and Europe individual TD-CDMA which NTT [dokomo] has propelled. Decides specification, ETSI calls the start of first service that it plans 2002. The occasion where the German government bet the license of portable telephone communication frequency on auction in 2000 August, conclusion doing with the successful bid amount which exceeds 90,000,000,000 mark in total, it became topic.

Unbuffered DIMM <[anbatsuhuado] DIMM>

Field:
Semiconductor > memory > RAM > Unbuffered DIMM

[rejisutadobatsuhua] (registered buffer) with the memory module product which does not build in LSI which is called. As for those which are installed you call Registered DIMM.

It is the circuit which is stabilized access by the fact that [rejisutadobatsuhua] transmits the sending and receiving of the signal substance chip set, and between memory chip adjusts the timing of the clock pulse and/or expands electric current. The amount operation which is not this circuit can produce Unbuffered DIMM to fast and cheapness, but because memory chip directly is connected to memory bus, it cannot make the number of memory chips per module 1 and the number of modules which can be installed in the motherboard excessively many.

As for Registered DIMM being it is widely used bulk, and the server etc where the use which is stabilized is required there is many a thing where Unbuffered DIMM is utilized in the general desktop personal computer and the notebook PC.
