IOPL (CONFIG.SYS directive)
IOPL stands for "Input/Output Privilege Level" and is a way for computer programs to access hardware devices directly.
Think of it like this - you're a kid in a classroom and you need to ask the teacher for a pencil every time you need to write something down. But what if you could just reach into the pencil box and get one yourself? That's kind of what IOPL does - it lets programs "reach into" the computer hardware and control it themselves, without having to ask the operating system (the teacher) for permission every time.
Now, the "config.sys" file is a special file in the computer that tells the operating system how to set things up before it starts running. It's like giving the teacher a list of things you need before class starts - you want a pencil, a piece of paper, and maybe a ruler. In the config.sys file, you can put a line of code that says "IOPL=ON". This tells the operating system that it should allow programs to access the hardware directly using IOPL.
So, to sum it up - IOPL is a way for computer programs to access hardware directly, and the "config.sys" file is a special file that can tell the computer to allow IOPL access.
