A virtual device driver (VxD) is a software device driver that emulates hardware and other devices so that multiple applications running in protected mode can access hardware interrupt channels, hardware resources and memory without causing conflicts. The Vxd was superseded by the Windows Driver Model (WDM) and is now obsolete.
In enterprise IT, Business Planning and Control System software (BPCS) is a type of enterprise resource planning (ERP) software.
Business Planning and Control System resources help with certain kinds of supply-chain issues, as well as other types of business processes and business planning. BPCS is also a specific proprietary type of ERP product developed by System Software Associates (SSA), now a subsidiary of Infor Global Solutions. The makers of the software estimate that it is use at over 8000 locations around the world.
One way that Business Planning and Control System software helps businesses is that it includes useful features for both financial planning and product or service implementation planning. Through analyzing and evaluating supply-chain processes, BPCS systems can help leaders and executives to plan better and create more efficient processes.
Business Planning and Control System tools can also be useful in that they often contain internal standards that provide consistency for users and IT professionals who may be developing them for businesses. One of these is consistency in modern programming standards, where consistent distributed computing designs can help make these systems more easy to use and integrate into a greater software architecture. Many of these systems also have client/server computing functionality that is up to a certain common standard, which, again, helps with installation and use.
