1. RAID

RAID is the acronym for a Redundant Array of Independent Drives. RAID specifies several "levels," 0, 1, etc. Different levels provide different options. One level allows you to combine multiple smaller drives into one, huge volume. Another level offers tremendous performance boosts by "striping" data across multiple drives such that reads and writes are split across the drives. If one drive fails, the other takes over until the bad drive is replaced. Once replaced, the RAID subsystem automatically restores the mirror.

2. Paradox Net Dir

The directory location of the Paradox network control file PDOXUSRS.NET. The active NET DIR parameter is stored in the Paradox section of the BDE configuration file and has precedence over any other NET DIR parameters that may be stored in older 16-bit configuration files, or in the System Init section of the current configuration file, or in the Registry. These other NET DIR entries will have no effect. To access a Paradox table on a network drive, the active NET DIR parameter in the Paradox section of the BDE configuration file must point to a network drive and folder in common to all users.

3. PSDP Checkpoints

A checkpoint is NOT a task, but rather a milestone. A point in the project that marks significant progress. Although PSDP contains many standard checkpoints, the executive sponsor and project manager must agree on the checkpoints they wish to track. Once established, tasks can be associated with a checkpoint and you can easily view what tasks are completed per checkpoint and what checkpoints do NOT have tasks established yet.

4. Event Handler

In computer programming, an event handler is part of event driven programming where the events are created by the framework based on interpreting inputs. Each event allows you to add code to an application-level event generated by the underlying framework, typically GUI triggers such as a key press, mouse movement, action selection, and an expired timer. In addition, events can represent data changes, new data, etc. Specifically, an event handler is an asynchronous callback subroutine that handles inputs received in a program.

A custom event is a programmer created event. For example, you can contrast an event handler with a member event, an OOP concept where you add an event to a class.
