Answer:

Source MAC address in the header

Explanation:

Store-and-Forward Switching is a Layer 2 switching method and it means that the LAN switch copies each complete frame into the switch memory buffers and computes a cyclic redundancy check (CRC) for errors. CRC is an error-checking method that uses a mathematical formula, based on the number of bits (1s) in the frame, to determine whether the received frame is errored. If a CRC error is found, the frame is discarded. If the frame is error free, the switch forwards the frame out the appropriate interface port

4G technology refers to the fourth generation broadband cellular network technology that is typically used for cellular communications on mobile phones and it is considered to have an internet speed that is ten times faster than what is obtainable on the third generation (3G) broadband technology.

Similarly, 5G is the fifth generation broadband cellular network technology that succeeded 4G and it offers higher quality in terms of performance, reliability, availability and efficiency.

As a result of the speed and high quality specifications of the 4G/5G broadband cellular network technology, they are widely used for various communications systems.
