OPERATING SYSTEMS, PART 2

Remember, our question last month was, "Is AOS/VS doing its job, and if not, what should be changed?" In the previous article (May, page 12), we developed a model (logical/physical separation, resource management, data integrity) that we can use to measure how AOS/VS stacks up as an operating system.

AOS/VS provides a consistent interface to most system resources, particularly with the read and write operations. For this, it scores very high marks.

Its problem, like most other operating systems (UNIX and MS-DOS are exceptions), is that its logical model is unique to the vendor, in this case DG. There being no standard operating systems for the ISO (International Standardization Organization) or any other standard bodies, the solution to this problem is still wide open. Vendors should make a concerted effort to develop a standard OS before a de facto one that few people can live with emerges.
