What is the main difference between queue and FIFO

[pkoti83]

May I know Both Queue and FIFO are same?

If yes, Why Queue has more methods than FIFO?

shall i replace a FIFO with Queue?

If i want to buffer the transaction which one is most preferable?

Yes. Queue is basically a data structure that uses the FIFO mechanism to store & retrieve data.

fifo means first in first out the data which entered first will come out first

Yes. Queue is basically a data structure that uses the FIFO mechanism to store & retrieve data.

Actually, it is the other way around. A FIFO uses a Queue data structure. A queue is just a data structure that allows easy access (insertion and deletion) to the head or tail of a queue. And you can access the n-th element of a queue. A FIFO enforces first-in-first-out access to the queue.
