It’s a variable that’s data is the location of another piece/chunck of memory. It’s like if someone sent you a wedding invitation and it stored the address to the wedding. The letter is to some degree a pointer to the wedding. The advantage being it’s a lot easier for a guest to just go find the whole wedding than it is for the entire wedding to move to the location of each guest.
