In modern plumbing, a drain-waste-vent (or DWV) is part of a system that removes sewage and greywater from a building, and regulates air pressure in the waste-system pipes to aid free flow.t the building drain system's lowest point, the drain-waste vent is attached, and rises (usually inside a wall) to and out of the roof. Waste exits from the building through the building's main drain and flows through a sewage line, which leads to a septic system or a public sewer.
A stack is also an internal memory usage scheme that is often used for function calls and other reference frames, as opposed to a heap, which is often used for more ad hoc memory usage. When people mention a stack trace or heap dump, this refers to internal memory usage. But that's probably not it, either. When people refer to a software stack or a full stack developer, this is a reference to an approach to software architecture that views software layers (or tiers) like a stack of pancakes. If you work on a client-server application and make changes to the back end database, maintenance layer, and web client, you are working on the full stack.
