Okay kiddo, do you remember when we go to a toy store to buy toys and sometimes the toy we want is not available? It's because the toy store ran out of stock or maybe the toy is not available in the store at all. Something similar happens with openhpi, which is an online platform for learning and education.
Openhpi is like a toy store, but instead of toys, it has education courses that people can take online. Now, sometimes people might want to take a course on openhpi, but they find that the course is not available. This could happen for many reasons, just like the toy store running out of stock.
But there's another reason why openhpi courses might not be available, and that is called "service availability". This means that the website itself, that is openhpi, might not be available for people to access the courses. Just like the door of the toy store might be closed, and we can't get in to buy the toys.
Now, service availability is important because if people can't access openhpi, they can't take the courses that they want to take. Just like if the toy store is closed, we can't buy the toys that we want. So, the people who run openhpi try very hard to make sure that the website is always available, so that people can access the courses whenever they want.
In order to do this, they put in place different measures like having a backup system, monitoring the website all the time, and fixing any issues quickly. Just like when we have a cold, our parents do things to make us feel better, openhpi does things to make sure that the website is always available.
So there you go kiddo, just like we love to go to the toy store to buy toys, people love to access openhpi to take courses. And, just like we hope that the toy store is always open and has the toys we want, people hope that openhpi is always available and has the courses they want to take.
