2 using the memory module of DDR SDRAM with 1 sets, by the fact that it reads and writes simultaneously, improve data rate. Being relatively cheap in comparison with when RDRAM and the like is utilized, you can anticipate the improvement of data rate.

Dual channel, memory of the same standard same capacity by the fact that it handles as one memory, with the technology which designates the data rate of memory as time, is one kind of parallel processing with two. For example, when trying probably to write the data of 2MB to memory, although it is decided that the data at a time of 1MB is written to the respective memory, writes the data of 2MB to one memory comparing, is sufficient half time.

In order to use memory with dual channel, it is necessary for chip set to correspond to dual channel. However, at the speed which exceeds FSB zone because data transfer is not possible, there are also times when data rate does not reach time depending upon the constitution of chip set and the like.

Specification of optical disk which was announced in 2004 August, integrates CD and DVD. Both sides are used in record, one side CD, already one side has become DVD.

The economic organization “DualDisc Consortium” where major music label each company of the world participates has lectured. On the CD aspect the usual music album, on the DVD aspect what records, various data such as image, photograph such as music data and promotion video and interview of the high sound quality by DVD-Audio and lyric is supposed.

We have become the specification where the CD aspect and the DVD aspect are equal to usual CD DVD, it is possible to play back with the general CD player and the DVD player and the personal computer etc, but because it is not the case that it is conformed to standard strictly, it is not guaranteed that it can play back.

As for the result which it searches, it is possible to transfer URL to carrying. In addition, it compiles the address register with the personal computer, can back up the address register “DUOADDRESS” “address register depositing, relief service” and, everyday it introduces the pleasant web sight other than “DUOBOOKMARK”, with the personal computer in also it reaches the point where it can participate “au auction”

It is low for the price personal computer of the AMD corporation 32 bit microprocessor. For the personal computer the strategic commodity of the same company in order to oppose low to the price processor “Celeron” of the processor most major Intel corporation.

With “Athlon” of the Pentium II/Pentium III opposite product of the same company with the processor of the inexpensive edition which uses the common processor core, it has the compatibility of the x86 processor of the Intel corporation.

The code name when developing was “Spitfire”. It changed to the core of the Athlon XP type, code name “Morgan” from 1GHz edition.

Mainly but low those which aimed for loading to the price is called “value PC” personal computer, low from the fact that it is the high performance at price, popularity is high even in the user of original machine inclination in comparison with Celeron
