  Store-and-forward switching is a switching technique used in networking where a switch receives an entire frame before it forwards it to its destination. During this process, the switch checks the frame for errors, CRC (Cyclic Redundancy Check) being one of the error-checking mechanisms. If the frame is error-free, the switch will store it temporarily in a buffer and then forward it to the appropriate port. If the frame contains errors, it will be discarded rather than forwarded.
