Each layer of the Open Systems Interconnection (OSI) model has one or more protocol data units (PDUs) associated with it; in the case of Layer 2, at which switching is executed, the PDU used is the frame. Do some research on the various frame types available for Layer 2 operations, and discuss, using diagrams, those frame types. Your paper should cover following questions:

• Which Layer 2 frame is now the commonly accepted standard? 
• What are its constituent components?
• What function does each of these components implement? 
• As part of this discussion, explain how and why frames can become malformed and what methods for error correction are implemented at Layer 2.
