Among the national qualifications regarding information processing, the qualification which recognizes the ability where you design & develop the electronic equipment which installs the microprocessor. Test was done the Ministry of International Trade and Industry (at that time) depending upon the National Examination for Information Processing Technicians center of the independent administrative corporate body information processing propulsion mechanism which is the designated test system. Test for recognizing has ended in 2000 limit, but presently “the technical engineer (the embedded system)”, is used in a way which succeeds the micro-computer applied system engineer.

MicroDIMM

Semiconductor > memory > RAM > MicroDIMM

DIMM was miniaturized, memory module standard for the notebook PC. Is adopted generally with the notebook PC the SO-DIMM standard which compared to one to turn and be small, width of pin side as for 38mm and height 30mm. The number and arrangement of pins are identical with SO-DIMM standard. As for type of memory there are many times when that time those of main current are used with DIMM, like DIMM similar, FPM DRAM, EDO DRAM and SDRAM they have changed. As for MicroDIMM in the memory module which is designed to for the lightweight small-sized computer like the sub notebook PC, really, it is adopted for the notebook PC under B5 size to be many. Because it was miniaturized, as for the maximum capacity per memory 1 restriction has become harsh in comparison with SO-DIMM.

Microdrive <Micro drive>

Field:
Storage > removable > Microdrive

The IBM corporation developed, the microminiature hard disk of PC card type.

There is CompactFlash in other things, as the storage unit which can be installed in the PC card slot that way, but if Microdrive because it is the disk, is the same capacity, it is cheap more substantially than CompactFlash which is one kind of semiconductor memory.

As for memory capacity the record of maximum 1GB is possible from 340MB, depending upon the model, capacity of 3 times is actualized in comparison with the most significant model of CompactFlash. Because of this, it is adopted in the superior type and the like of digital camera which needs the big storage unit with the improvement of efficiency.

As for Microdrive driving the motor, turning the disk, in order to do the reading and writing of the data, electric power consumption becomes many in comparison with the storage unit of semiconductor memory type. Because of this, the continual drive time in the equipment which is driven with the battery becomes shorter than CompactFlash.

Micro Hard Drive <Micro hard drive>

Storage > removable > Micro Hard Drive

Microminiature external hard disk of [imeshiyon]. The microminiature size, to which the first model which is sold in 2006 January builds in 0.85 inch hard disk of 4GB, as for substance size 40mm×82mm× thickness 16mm, weight 52g. Rather than you connect with the personal computer itself with USB, calling the external hard disk the product of the appearance such as bulk edition of USB memory.
