Your best bet is to start with the man pages for any command you don't know, try running 'man mount' and if that doesn't answer your question then search the internet further with a more specific query.

Mounting is the act of mounting or attaching some form of media; hard drive, CDROM, DVD Writer, Tape drive, etc to the Linux file system tree to allow the device to be accessed.

Most drives, etc are attached to the /mnt directory where /mnt is the 'mount point'.
Some Linux distributions mount memory cards and USB devices to a directory called /media. As the Linux file structure is a tree, you can add a mount point of your own anywhere you want (though it would possibly be in your /home directory somewhere.)

If you CD to the mount point you are effectively looking at the top level of the mounted media. If there's nothing mounted, you'll find a file called "lost & found" and possibly any files which were saved to the 'non-mounted' media in error.

Welcome to Linux Questions, hope that helps a bit.

Play Bonny!

Giving an example:

When you attach your usb/pendrive to your computer, it's mounted(read by your OS ) to a mount point(where you can read it and its contents).
If your Operating System supports the formatted filesystem of the external ,then its automatically mounted otherwise you have to manually mount by command or any GUI.

bdf command displays the amount of disk space available on the filesystems mounted in different mountpoints in Unix.

The best depiction I'm aware of that is not bit for bit.

A Mount-Point is somewhat of a (argument/parameter) in programming) and or a piece of configuration data for another application like your Virtual File System. A mount point is data that your File System needs to accomplish addressing, (find) whatever you want to access. For some reason your computer is not allowed to address (open) every file on your Hard drives by default. It must be 'Mounted'.

This is a completely non-technical but practical way of thinking about a mount point: Think of a mount point as a virtual directory that contains the file system of the mounted device. Mounting a device merely means that you are making its file system available to the system.

As an example, suppose that you have an SD card and you insert it into your computer. If your version of Linux doesn't auto mount then you have to manually mount the card using the mount command. Suppose you mounted it as /mnt/SD. /mnt/SD is the mountpoint. If you navigate to mnt and click on SD then you will see all the files and directories on that SD card.
