Some data structures,
derived directly from TObject :
"A data type that can store values without any particular order and no double ups" (wikipedia)
"A collection of elements. Push adds an element to the collection and pop removes the most recent added element. Alternatively called LIFO (last in first out)." Wikipedia.
"A collection of elements maintained in order. Enqueue adds elements to the rear and dequeue removes elements from the front. Hence FIFO (first in, first out)." Wikipedia
"A collection of elements identified by at least one index or key." Wikipedia
