It was standardized the American Electronics Industries Association (EIA) by, one of standard of serial communication. It is loaded onto the Macintosh series and the like which is the personal computer of the Apple corporation.

As for maximum length of cable with 1.2km, as for the highest transmission speed 10Mbps. Although peripheral device personal computer itself and such as printer, modem and scanner is connected, it is used. There is many a thing where those of the D-sub25 pin are used in the connector.

As for RS-422 itself most as for the compatibility of RS-232C of the serial standard which has spread it is not, but, the serial port of Macintosh is designed connecting also the RS-232CRS-232C product, in order to be able to utilize. As for the RS-422 port it is not loaded onto the Macintosh series after iMac.

RS-485

The higher rank of RS-422 we have become interchangeable, it corresponds to the multipoint connection of bus type RS-232C communication standard only of pair one connection, vis-a-vis being the communication standard where RS-422 corresponds to pair plural multidrop connections, it is maximum and it corresponds to the plural anti- plural connections up to 32.

Other specifications to conform to RS-422, as for maximum length of the cable with 1.2km, as for the highest transmission speed 10Mbps. Although peripheral device personal computer itself and such as printer, modem and scanner is connected, it is used. There is many a thing where those of the D-sub25 pin are used in the connector. As for RS-485 but when it is used for the computer for business the majority, for the personal computer RS-485 interface extremely part it exists.

One of the public key cryptosystems which 3 people Ronald Rivest, Adi Shamir and Leonard Adleman developed in 1978. Taking the name of the developer, it was named. To be wide it has spread as a open key cryptographic standard. RSA code is deciphered, it is necessary prime factor to disassemble enormous integer, heuristic method of the key whose efficiency is good still has not been found. As for the patent regarding RSA code the RSA Data Security corporation possessed, but the expiration was entered in 2000 September.

The multimedia card (MMC) MMCA which is the standardization group (MMC Association) announced in 2002 November, flash memory card standard. It is the superior interchangeable memory card which miniaturizes MMC where the German Siemens corporation and the SanDisk corporation enact in 1997.

But as for RS-MMC function and the number of pins, thickness the same as MMC, size width 18mm× depth 24mm× thickness 1.4mm, weight 0.8g and MMC approximately half size, has become weight. Size it is possible with the adapter to make the same as MMC, it is enabled even in the existing MMC corresponding slot. Those of MMC can use also the development tool and the like.

RS-MMC the new product of capacity 16MB, 32MB and 64MB was shipped in 2002 November by Hitachi, Ltd. In addition, the same company 128MB, the 256MB model has designated that it commercializes as goal on 2003 latter half.
