Final answer:
The MAC sublayer of the Data Link layer in the OSI seven-layer model creates and addresses the frame, handling data encapsulation and network node addressing.
Step-by-step explanation:
The component of Layer 2 of the OSI seven-layer model that creates and addresses the frame is the MAC sublayer. The MAC (Media Access Control) sublayer is responsible for the data encapsulation with frame delimiting and addressing. The Data Link layer in the OSI model is divided into two sublayers: the Logical Link Control (LLC) and the MAC sublayer. The MAC sublayer controls the way that computers on the network gain access to data and permission to transmit it and also handles the addressing of frames for transmission between network nodes.
