Okay, kiddo, let me explain what a batch queue is in a very simple way.
Imagine you have a big pile of toys that you want to play with, but you can only play with one toy at a time. So, you decide to make a list of all the toys you want to play with and put them in order. This list is called a batch queue.
Similarly, in a computer, there are lots of programs or tasks that need to be run. However, the computer can only run one program at a time. So, just like you made a list of toys, the computer makes a list of all the programs that need to be run and puts them in order. This list is called a batch queue.
When the computer is done running one program, it moves on to the next one in the batch queue. This way, the computer can work efficiently and get lots of tasks done one after the other.
So, a batch queue is just a list of programs/tasks that need to be run in order by the computer. Just like your list of toys to play with!
