The FIFO principle stands for "First In, First Out."
You can think of it like waiting in line at a coffee shop. The first person to get in line is the first person to get served.
In computer science, FIFO means that the items are processed in the order they come in. This is really important for things like planning tasks and managing resources.
Here are a few types of queues that show how FIFO works:
Simple Queue: This is the basic type of queue. You can add items at the back and take them out from the front. It’s pretty easy to see how FIFO works here.
Circular Queue: This kind connects the end of the queue back to the front. It helps solve the problem of wasted space in simple queues. So, when you take items out, it makes sure that no empty spots are left behind.
Priority Queue: This one still uses FIFO, but there’s a twist. Items are processed based on how important they are, not just the order they arrive. So, if something is really important, it can be served before others, even if it came later.
Knowing about the FIFO principle is important for using these different queues the right way. Each type of queue has its own purpose, and knowing when to use each one helps make computer programs work better.
