What are queues?

Answer 1

A queue is a first-in, first-out data structure. We use queues when one thread needs to communicate with another but they operate at different frequencies (asynchronously), such that the first thread may produce input for the second thread faster than the second thread can actually process each input. Thus the first thread will place each input on a shared queue and the second thread can deal with each in turn as and when it is ready. To avoid data races, all operations that modify the queue must be mutually exclusive, such that only one thread can gain access to these operations at any given moment. This can be implemented using a lock, such that only one thread can "own" the lock while all others must wait until the lock is released.

Answer 2

A line of people. British English. It can also mean a line of vehicles, for instance. There are 2 other meanings: In computers, data which is awaiting to be processed. Also, a braid of hair in the back of the head - like a pigtail - origined from the french, which was the first meaning of queue.

Answer 3

In Data Structure:A list of computer data constructed and maintained on a first in, first out basis.In Data Structure:A list of computer data constructed and maintained on a first in, first out basis.

Answer 4

according to data structure,queue follows the property of first in first out.

for example:

a line of people standing at bus stand,the person who came first will enter the bus at first then second,then third and respectively:

similarly elements stored in element will be deleted from the first and entered at last

this is called FIFO-first in first out;

Answer 6

The queue is a linear data structure where operations od insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.

Answer 7

1.Queue is data structure.

2.Which is uses store Dynamic time data in specified order,

and it is based on FIFO (first in first in first out) concept.
