Queuing delay

Imagine you are at a candy store and there's a long line of people in front of you. You really want to buy your favorite candy, but you have to wait for all the people in front of you to buy their candies first. This waiting time that you experience is similar to queuing delay.

Queuing delay happens when too many things are trying to use the same resource (like a network or a server) at the same time. Just like the line at the candy store, when there are too many requests for a resource, they have to wait in line for their turn. This waiting time is called queuing delay.

The queuing delay can be affected by a few things. First, it can depend on how long it takes for each request to be processed. If each request takes a long time to be processed, the queue of requests waiting will be longer, and you will have to wait for a longer time.

Second, the queuing delay can also depend on how many requests are in the line. If there are a lot of requests waiting, it will take longer for your request to be processed and for you to receive a response.

Overall, queuing delay is when you have to wait in line for a resource to become available. It can happen when too many things are trying to access the same resource, or when it takes a long time to process each request.
