Which vendor is associated with MAC address 00:02:78:--:--:--?

Explanation:
MAC addresses carry an Organizationally Unique Identifier in the first three octets, which identifies the vendor. The prefix 00:02:78 is assigned to Samsung Electro-Mechanics Co., Ltd, so a device using this MAC would be associated with Samsung Electro-Mechanics. The remaining three octets are vendor-specific and don’t reveal the manufacturer. You can verify by checking the OUI 00-02-78 in the IEEE OUI database or a lookup tool; the other vendors listed have different OUIs, so they wouldn’t match this prefix.
