Detailed explanation-1: -Explanation: FIFO queuing sends packets out an interface in the order that they had arrived and does not make a decision about packet priority. All packets are treated equally.
Detailed explanation-2: -FIFO with tail drop, as the simplest of all queuing algorithms, is the most widely used in Internet routers at the time of writing. This simple approach to queuing pushes all responsibility for congestion control and resource allocation out to the edges of the network.
Detailed explanation-3: -The queuing algorithm can be thought of as allocating both bandwidth (which packets get transmitted) and buffer space (which packets get discarded). It also directly affects the latency experienced by a packet by determining how long a packet waits to be transmitted.
