INT 10H
`int 10h` is a special command that we use when we want to talk to our computer's screen. It is like we are asking the screen to do something for us.
Imagine you have a magic box that can do a lot of things, like drawing pictures on paper. You can tell the box what picture you want it to draw, and it will do it for you.
In the same way, our computer has a special "box" called the video display that can do things with our screen. We can use `int 10h` to talk to this "box" and ask it to do things for us.
When we write `int 10h` in our computer program, it means that we want to use this special command to talk to the video display. We can give it a specific number called an "interrupt number" which tells the video display what we want it to do.
For example, if we give it the interrupt number 0Eh, it means we want the video display to draw a character on the screen. We can also give it other numbers for different things we want it to do.
When the video display receives the interrupt number, it knows what to do and it follows the instructions that come after it. This way, we can use `int 10h` to make our program show things on the screen or change how things look.
So, in summary, `int 10h` is a special command that we use to talk to the video display in our computer. It helps us draw things on the screen or change how things look.
