Sandbox Java program execution environment of security
Sandbox (sand) concept is to ensure that users download the Java applet (ie, applets), the program can only be carried out under a limited environment.
Sandbox original literal meaning shall be children's games with the bunker, quite similar to the game-bed. In the Java concept, we can use the concept of relative terms sandbox, assuming you have relatives and children to your home to play with her on the sand you would (or should we say gaming bed), on the one hand not only protect her on the other hand She is also to avoid the run around smashed home valuables.
Similarly, although the user likes to download all kinds of Java applets, but do not want to accidentally program the opportunity to have been dishonest invasion ruined the system.
Sun in the sandbox policy has been opened, according to users and to set different trusted executable code for more tasks, or set up limited to only perform specific tasks. In the Java 2 version, even without the signature code may also be given full system privileges, which are fully in accordance with company requirements.

SAR technical standards for mobile phone radiation
SAR value simply refers to mobile phones in the electromagnetic waves generated by heat, impact on the human body measurement data, unit is W / Kg (W / kg). Currently the U.S. Federal Communications Commission (FCC) published by the safety standards of mobile phone value of 1.6, so as long as the mobile phone's SAR value below 1.6 are in the safety standards of products. SAR values indicated that mobile phones can cause the body heat would be little affected by the greater value, indicating the greater impact on the human body; the other hand was less affected.
In addition, according to World Health Organization International Telecommunication Union and the SAR value of demand, GSM and CDMA mobile phone electromagnetic radiation must be certified at the international authority of a license within the scope of the WHO (ITU standard limit of 2.0). Sections of the SAR value of mobile phones depends on the size of the main antenna, design and other factors, rather than the mobile communications network technology.
SAR test method is to mobile phones on human ear and right ear, were tested up, down, left, right out of the four directions of the distribution of heat, derived from the average of the last.

SAS Serial Attached SCSI
SAS is the next generation of SCSI technology and the gradual emergence of Serial ATA (SATA) disk the same sequence-based technology are taken in order to obtain a new higher-speed interface.
SAS is not only to improve storage system performance, improve availability and scalability, while strengthening and SATA Compatibility between the disk and reduce cable to improve the system of internal space, at present, including Seagate Technology (Seagate), Maxtor, and other disk manufacturers, and IBM, HP and other server vendors are SAS standards advocate.
By SCSI Business Association (SAT; SCSI Trade Association)'s Serial ATA II Working Group to promote, SAS and SATA's physical size has been made in the agreement, SAS and SATA disk technology can be compatible, both can co-exist among one storage system Thus, enterprises can use a different interface to meet all kinds of hard drive performance or capacity in the application of different needs, so that storage devices to maximize the investment returns.
