What is the full form of OEM
OEM: Original Equipment Manufacturer
OEM stands for "Original Equipment Manufacturer". Its meaning has evolved over the time. In earlier times, it referred to a company that manufactures products to be used as components by another company in its end products. For example, if Acme Manufacturing Co. manufactures power cords to be used on Dell computers then Acme is the OEM.
On the contrary, in recent times, OEM refers to a company that uses products manufactured by other companies as components in its end products or rebrands the manufacturer's product to sell it under its own name. For example, most of the PC vendors such as HP, Lenovo and Dell who don't have their own manufacturing units are OEM. They assemble the manufacturer's components and brand the end product with their own logo.
