21. This was meant to replace the manual method of creating operating system interfaces for IP Pascal. 22. The system interface is the HAL I / O ( HIO ) bus, a 64-bit asynchronous bus. 23. These ATs are expected to have a detailed understanding of how the systems interface with the aircraft. 24. For example, Zip drives come in parallel port or small computer system interface ( SCSI ) connections. 25. One group in Palo Alto worked on the underlying operating system interface to the hardware and programming tools. 26. The executable formats are registered through a special purpose file system interface ( similar to / proc ). 27. The resulting energy gap became populated with topologically protected one-way modes, which traveled only at the system interface . 28. The interface through which bridging systems communicate with each other is the Bridging Systems Interface ( BSI ). 29. It is the people at the human-system interface whose actions can, and sometimes do, have immediate adverse consequences. 30. I3C adds a significant number of system interface features while retaining upward compatibility with existing I2C slave device designs.
