The _________ layer of the OSI Model provides services for error detection and correction.

  • Physical
  • Data Link
  • Network
  • Transport
The correct option is Data Link. The Data Link layer of the OSI Model is responsible for error detection and correction. It ensures that data packets are transmitted without errors over the physical layer by using techniques like checksums and CRCs (Cyclic Redundancy Checks). This layer also handles framing, addressing, and flow control. Physical layer deals with the actual physical transmission of data, Network layer is responsible for logical addressing and routing, and Transport layer manages end-to-end communication.
