layer 4
Data Link layer does the parity error checking Thanks, Samaresh
Data link Layer
Data link error control checks for error in each router and end-system, but transport layer error control checks for error only at the end-systems.
Middle layer of osi model is Transport layer functions: 1.Segmentation of data 2.connection managment 3.flow control of data 4.Error checking
The transport layer manages packing and unpacking of data, the delivery of packets and checking for errors in the data once it arrives.
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.
Application Layer
Conversation Multiplexing Segmentation and Rassembly Error Checking
It handles Error Recovery, flow control (synchronization) and seqencing (which terminals are send and which are receiving).It is Considered the "Media access control layer"and is where MAC Addressing is defined.Answer:Data Link Layer
hii frnds it provides framing error control, flow control and link management, error detection and correction
error control and recovery flow control ppp(point to point protocol transfering from physical layer to network entities
transport layer
