1.	The devices that convert serial to parallel and parallel to serial are called?(a) Serializer/Deserializer(b) Transmission converters(c) Multiplexer(d) PreemphasizerThis question was addressed to me in an internship interview.The query is from Parallel and Serial Transmission topic in section Digital Communication Techniques of Avionics
Answer» The correct option is (a) Serializer/Deserializer For explanation: Parallel transmission is high SPEED and serial data can cover LONGER distances. Hence they are USED INTERCHANGEABLY and the devices which convert serial to parallel and parallel to serial transmission is called serializer/deserializer device (SERDES).
