System.Collections.Generic.Queue

Added in .NET 2.0
Represents a generic queue of objects
A queue represents a first-in, first out collection (FIFO)
items are added with "Enqueue" and removed with "Dequeue"
The "Peek" method retrieves the oldest object but does not remove it.
For example you might want to send messages to a resource that can only handle one message at a time.
The queue class is a good collection to use when you are managing a limited resource
