IIRC, the term started around Oracle version 5. The following is based on memory ...

Prior to Oracle5, a common way of having an application interact with the database was to use the database kernel more as a library which you linked to your application. The app and the database were bound and no separate 'instance' was used. The application and the database ran in the same process space and were said to be a 'single task'.

Two-task was used to refer to the operational mode where your process (task) and the instance's 'shadow' process (task) that was dedicated to your process communicated using a method like SQL*Net.

Now two-task simply implies a dedicated server rather than multi-threaded server operation.
