Layer 2 - The Data Link Layer
Layer 2 of the OSI model provides error-detection capability
Network Layer
Transport layer is the fourth layer in the OSI model. Transport layer is responsible for process to process delivery of entire message. Other than that it also control connection, flow of data and error , thus will resend the packet if it get lost in between.
osi modal is deovaped by iso company it has 7 layers but ATM modal has a 4 layers osi modal have a physical layer,datalink layer,network layer, trasport layer, session layer, perastion layer, application layer, but
it comes in the first layer, or popularly known as the physical layer. must not be confused to be in datalink layer.
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Data Link layer does the parity error checking Thanks, Samaresh
The Transport Layer and Data Layer can provide error detection and correction at the different levels of data transmission. Network layer can also correct errors if it detects them.

The layer responsible for issuing acknowledgments in the OSI model is the Transport layer, which is the fourth layer. It ensures reliable data transfer through error detection and correction, as well as flow control mechanisms. Protocols like TCP (Transmission Control Protocol) within this layer handle the acknowledgment of received packets to confirm successful delivery.
The mechanical layer that sits on top of the physical layer in the OSI model is the data link layer. This layer is responsible for node-to-node data transfer and error detection and correction, ensuring reliable communication between devices on the same network. It encapsulates the raw bitstream from the physical layer into frames, adding necessary addressing and control information.

The Layer for the TCP Protocol Data Unit (PDU) is called the Transport Layer. In the OSI model, the Transport Layer is responsible for end-to-end communication, ensuring reliable data transfer, error correction, and flow control. TCP (Transmission Control Protocol) operates at this layer, providing a connection-oriented service for transmitting data between applications.

The layer of the OSI model that addresses how data between applications is synced and recovered if messages don't arrive intact is the Transport layer (Layer 4). This layer is responsible for ensuring reliable data transfer, including error detection, correction, and flow control. Protocols like TCP (Transmission Control Protocol) operate at this layer, providing mechanisms for data integrity and retransmission of lost packets.
