Retail - This is a boxed copy, which can be obtained from a retail store or online from the Microsoft Store. You can transfer the Retail Windows 10 copy to various hardware, e.g. to another PC.
OEM - This license is locked to the specific hardware produced by the original equipment manufacturer (OEM). You cannot transfer it to another PC. It is locked down to the specific machine with a special product key which can be flashed into UEFI or BIOS.
Volume - This license type is used in big companies. It is a license used mostly for business, government and so on. It cannot be used on PCs other than those associated with the company. The Volume product keys are either used with a KMS server or Multiple Activation Keys (MAK) where a single key can be used on multiple PCs. Not all editions of Windows 10 support the ability to be activated this way.
