Standards

This part of the ISO/IEC 9314 specifies the Media access control (MAC) the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDD). FDDI (ISO/IEC 9314) provides a high- bandwidth (100 Mbits) general - purpose interconnection among information processing systems, subsystems and peripheral equipment, using fiber optics or other transmission media. (FDDI can be configured to support a sustained data transfer rate of at least 80 Mbits/s (10 Mbyte/s). FDDI provides connectively for many nodes distributed over distances of many kilometers in extent. Certain default parameter values for FDDI (eg. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 500 nodes and 100 km of dual fiber cable, respectively) however, the FDDI protocols can support much larger networks by increasing these parameter values.

This International standard defines an input/output bus for interconnecting computers and peripheral devices. It defines extensions to the small computer system interface (ISO 9316:1989), referred to herein to herein as SCSI-1. Its also provides more complete standardization of the previously characteristics of the interface to allow inter-operability of conforming devices. This International standards is referred to herein as SCS1-2. The term SCS1 is used wherever it is not necessary between the two version

This International standard defines the common access method (CAM) for the small computer systems interface (SCSI). The purpose of this International standard is to define a method whereby multiple environments may adopt a common procedure for the support of SCSI devices. The CAM provides a structural method for supporting peripherals with the software (e.g. device driver) and hardware (e.g. host bus adapter) associated with any computer.
