working set

 

Resources you select to view or operate on as a group. For example, you can create a working set to speed up a search by restricting its scope. A working set can also help you focus by reducing the number of projects visible in the Project Explorer, the number of symbols displayed in the Outline view, and so on.

workspace

 

The central location for all the resources you see in Workbench: your projects, folders, and files. Workbench uses the workspace to store settings that describe your working environment: which projects and views are currently open, how you have your views arranged within the perspective, whether you have breakpoints set, and so on.

The default location of the workspace is installDir /workspace. To keep your projects completely isolated from each other, you can create more than one workspace.

To share the build objects of your projects with a target, the workspace (directory) may be in a file system that is exported to the target, or you may redirect build objects from your workspace to a location exported to the target.

NOTE: This use of the term workspace is entirely different from the flash workspace, which is a small area of RAM needed to run the flash algorithm; that sense of the term is restricted to flash programming.

z-order

 

The z-order is the placement of windows along an imaginary z-axis that extends out from the display, perpendicular to the display itself. This stacking order determines visible and or obscured windows when other windows overlap or occupy the same area on the display.

Zero-copy sockets

 

Zero-copy sockets are an alternative set of socket calls based on a data abstraction called a zbuf, or zero-copy buffer. Zero-copy buffers are a data abstraction designed to allow software modules to share buffers without unnecessarily copying data. Alternate terms include zero-copy bufferzero-copy socket, and zbuf.
