OEM Full Form is Original Equipment Manufacturer. Originally, this term was used to refer to the actual manufacturer of any product. Though the product might be sold to other companies to be resold and rebranded, the OEM referred only to the original maker of the product. Whereas; currently, the manufacturer or the reseller-whoever reaches the product to the end customer, is termed as OEM. So in other words, OEM is the value-added reseller of a product.
In the IT world, the variations in OEM include; hardware OEM and software OEM. Hardware OEM refers to companies that acquire a vendor’s products and resell it by rebranding the same. This may not involve any modification to the original product. On the other hand, a software OEM embeds another vendor’s software technology into its application.
