Explain the encoding process in ETHERNET?

In computers, encoding is the process of putting a sequence of characters (letters, numbers, punctuation, and certain symbols) into a specialized format for efficient transmission or storage. Decoding is the opposite process the conversion of an encoded format back into the original sequence of characters. Encoding and decoding are used in data communications, networking, and storage. The encoding in Ethernet work just like that the encoding scheme used in Ethernet is Manchester encoding.

            Manchester Encoding specifies that a 1 corresponds to a transition from 0 volts to a positive voltage level. Correspondingly, a 0 corresponds to a transition from a positive voltage level to zero. Furthermore, the transitions occur in the “middle” of the time slot allocated to a bit, which allows the signal to return to the previous level in case the data contains two repeated 0s or two repeated 1s.
