CD it isfor music. In ordermusic sampling frequency 44.1kHz, to record digitally with PCM system of the quantization 16 bit, whatever degree hearing different from the analog record, the sound quality does not deteriorate. Soundof 80 parts can be recorded in CD of 12cm. The specification of CD-DA is called alias "red-book " from the fact thatthe coverof the standard book is red.

The information regarding the music which was recorded in music CD, the databasein orderto offer to the CD playback software and the peripheral device of the user.

Whenmusic CD is set to the CDDB corresponding equipment,the software accessing CDDBautomatically,whilesearching & downloading the information of CD, referring to the information such as tune name artist name and the like,it is possibleto play back CD.

On the personal computer,the principal media playerof Win AMP, Windows Media Playerand RealJukeboxetc. builds in the cooperation function of CDDB, or the plug in software because cooperation function can be given is offered.

As for early CDDB because it does not correspond to 2 byte letter such as Japanese, in Japan the manufacturer of part for traditional music CDof individual standard had startedthe CDDB server. Multi language environment were improved from CDDB2, reached the point where it can correspond to also Japanese and the like, butthe licensebeing necessary in connectiontothe CDDB2 server, the problem that exists it is difficult to correspond with the free software.

Network technology network control CDDI

Token passingsystem is adoptedfor access control,oneof the LAN standard where the communication of 100Mbps is possible frommaking useof twisted pair line. Most specificationsare commonwith FDDI whichusesthe optical fiber, but in the transmission line the cheap copper wire (the metal cable) using is a special feature.

UTP of category 5 (from the nonsealtwisted pair line) cable or STP(twisted pair line)the cableis used to the cable, from the sealed attachment. Thisbeingthe same as those which are used with Ethernet, RJ-45of connectorformiscommon with Ethernet.

The highest transmission rateisthe same as FDDI 100Mbps, but in order to use the copper wire, it is weak in noise, as for maximum transmission distance is restricted to 100m (as forFDDI 2km).

Useas the basic network whichtiesbetween the network which is formedwith FDDI similar and 10BASE-T was anticipated, but because the 100BASE-TX standard whichactualizesthe speed of 100Mbps with the UTP cableof the samecategory 5 appears, CDDI was not excessively utilized.
