Simple..! Encoder is an electronic device which converts ordinary language into code(for security reasons encoding will be done), And Decoder does the reverse of it!

encoder used to cypted data from genuine to crypted and decoder is used to ecnrypted crypted data to genuine data. this is usually called as codec.

'encoder' is a device or software that converts original or raw data to another form, practically used for encryption and/or compression, while 'decoder' is the opposite, reverting the form to its original or raw state
