Okay kiddo, so imagine you want to have a tea party with your friends. You need tea, cups, and saucers to make it happen.
Now, let's say you want to have this tea party every day. You don't want to keep getting everything yourself every day, right? So, you decide to get some help. You ask your mom to set up everything for the tea party ahead of time so you don't have to worry about it every day.
But, what if your mom is busy or forgets? That's not good for your tea party plans. So, instead, you hire someone to do this for you. This person is called a "service".
A service is someone or something that helps you get things done that you need. In the case of your tea party, the service is someone who makes sure you have everything you need for your tea party every day.
In the bigger world of computers and technology, services are kind of like your tea party helper. They are programs or machines that help other programs or machines do their jobs. For example, if you have a website, it needs a service to handle requests from people who want to see the website. That service makes sure the website is available and running smoothly.
So, just like you need a tea party helper every day so you don't have to worry about getting everything yourself, computers and technology need helpers called "services" to make sure things run smoothly.
