When you use a computer, you need to be able to access files and folders that are stored on different devices like hard drives. That's where "mount" comes in. It's like putting your favorite toy into your toy box - you're making it available to play with whenever you want.
When you "mount" a device, you're telling your computer to make it available for you to use. Think of it like plugging in your USB stick - you can't use it until you "mount" it by opening up the files.
The process of "mounting" a device is like creating a bridge between your computer and the device. Once this bridge is created, you can access the files and folders that are stored on the device.
For example, let's say you have an external hard drive with all your favorite movies on it. You would need to "mount" the hard drive to access your movies. Once you do this, the computer will recognize the hard drive as a new device and you can access your movies just as if they were stored on the computer itself.
Overall, "mounting" is a way to make different devices and their files accessible to you on your computer.
