Red Book <Red-book>

Audio CD (CD-DA) specification. Besides the fact that sampling rate and the number of channels and the range etc of the frequency which can be recorded are stipulated, also the specification which is applied to all CD not just, audio such as physical specification of disk and recording mode of the signal CD, includes many.

As one example, 1 frames (block) as for thing and the data which are formed at 2352 bytes it is stipulated with Red Book that you write from the inside perimeter and the like. With Red Book the territory for expansion (the jumper wire) we have prepared, the standard which expands the audio CD of CD-TEXT and the like is actualized by utilizing this jumper wire.

As a data error correction function CIRC is prepared even with Red Book, but when it cannot make error cannot correct with CIRC it has become the music unique specification that it compensates the data around in reference. By the way, the name of Red Book is derived from the specification having done the cover of red.

Red Hat Linux <[retsudohatsuto] Linux>

The Linux distribution the Red Hat Software corporation developing & selling (the distribution package). With the distribution where the user is most, Red Hat Linux individual package management mechanism RPM is adopted for also other many distribution. The individual system construction utility is prepared large number, also maintenance has become easy. Many application software is corresponding commercial business/regardless of free.

Registered DIMM <[rejisutado] DIMM>

Semiconductor > memory > RAM > Registered DIMM

The memory module product which builds in LSI which is called [rejisutadobatsuhua] (registered buffer). As for those where this is not installed you call Unbuffered DIMM.

[rejisutadobatsuhua] taking in the signal which is output from chip set of the substance once, adjusting the timing of the clock pulse and/or arranging the ripple mark of electric current and/or expanding, it outputs to memory chip. Because of this, stabilizing the access to memory, it is possible to do.

In addition, burden to memory bus to be lightened, can increase the number of memory chips per module 1 and the number of modules which can be installed in the motherboard, due to the fact that the buffer circuit mediates memory access (if number the same from stabilizing, it can access,). However, [reitenshi] increases in order to put the buffer circuit to the middle, access speed decreases somewhat.

Reiser File System <ReiserFS>

Field:
OS > Technology > file system > Reiser File System

One of the file systems which are utilized with Linux. Same as the ext3 file system journaling function (the function which manages data modification as transaction) we have, the time when it requires for obstacle restoration has decreased. In addition, you can list the fact that it is superior in performance disk use efficiency of the partition where the small file is many as the major feature of ReiserFS. As for ReiserFS because there is no ext2 and compatibility which are widely used until recently, it accesses the ReiserFS partition, the correspondence of OS becomes necessary, but ReiserFS was supported with 2.4.1 kernels.
