What is the main difference between queue and FIFO

SystemVerilog

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?

Hi dave,

Thanks a lot for your reply.

I have one more doubt after going through the reply i.e.

can i say FIFO is absolutely same as QUEUE?

Shall i use ‘queue’ for buffer applications rather than ‘FIFO’?
