Terminate-and-stay-resident program

Okay kiddo, have you ever played a game or used an app on your tablet, and then minimized it to do something else, but you still wanted the game or app to keep running in the background? That's kind of like what a Terminate-and-Stay-Resident (TSR) program does.

TSR programs are special applications that can run on your computer, but instead of closing completely when you're done using them, they stay active in the background. This means that you can use your computer for other things, while the program keeps doing its job.

For example, let's say you have a TSR program that helps you print things faster. You can open the program when you need it, and then minimize it. This way, the program will keep working in the background while you do other things on your computer. If you need to print something later, you can easily maximize the program again and it will be ready to use.

So, in short, a TSR program is a special type of software that can stay running in the background of your computer, letting you keep using your computer for other things while the program does its specific job.
