An OEM (Original Equipment Manufacturer) is a company that produces parts or equipment that may be marketed by another manufacturer. For example, a company that makes computer components, like motherboards or graphics cards, can be considered an OEM if those parts are sold under another brand's name. OEMs play a crucial role in various industries, including automotive, electronics, and appliances. They often provide specialized products that meet the specifications of the brand that sells them, ensuring quality and compatibility. This collaboration allows brands to focus on marketing and distribution while relying on OEMs for production expertise.
