Card sorting is a technique in user experience design in which a person tests a group of subject experts or users to generate a dendrogram (category tree) or folksonomy. It is a useful approach for designing information architecture, workflows, menu structure, or web site navigation paths. Card sorting uses a relatively low-tech approach.
Queue overflow results from trying to add an element onto a full queue and queue underflow happens when trying to remove an element from an empty queue. A bounded queue is a queue limited to a fixed number of items. [1] There are several efficient implementations of FIFO queues.
A breadcrumb or breadcrumb trail is a graphical control element used as a navigational aid in user interfaces and on web pages. It allows users to keep track and maintain awareness of their locations within programs, documents, or websites.

For example, if a modem expansion card is added into a system and assigned to IRQ4, which is traditionally assigned to the serial port 1, it will likely cause an IRQ conflict.

Once items were placed in a cart, buyers wanting to check out were put into a queue until they got to a final area to enter credit card information. Last year, the singer overhauled her store ...
Another use of a priority queue is to manage the events in a discrete event simulation. The events are added to the queue with their simulation time used as the priority. The execution of the simulation proceeds by repeatedly pulling the top of the queue and executing the event thereon. See also: Scheduling (computing), queueing theory
