How is an encoder different from a decoder?(a) The output of an encode

1.	How is an encoder different from a decoder?(a) The output of an encoder is a binary code for 1-of-N input(b) The output of a decoder is a binary code for 1-of-N input(c) The output of an encoder is a binary code for N-of-1 output(d) The output of a decoder is a binary code for N-of-1 outputThe question was posed to me by my school principal while I was bunking the class.Asked question is from Encoders in portion Combinational Circuits of Digital Circuits
Answer» Right choice is (a) The output of an encoder is a binary code for 1-of-N input For EXPLANATION I WOULD say: An encoder is a combinational circuit ENCODING the information of 2^n input lines to n output lines, THUS producing the binary equivalent of the input. It performs the opposite operation of a decoder which results in 2^n outputs from n INPUTS. Thus, an encoder different from a decoder because of the output of an encoder is a binary code for 1-of-N input.
