Week 3 Individual assignmentNTC/360Synchronous and asynchronousSynchronous and asynchronous data transmission are two ways for transmitting data over thenetwork.With the help of an external clock transmitter the synchronization of the signal is doneand the transmitter and receiver have the knowledge of the voltage level and understands thevoltage level and thereby understanding the voltage and the corresponding bit.So the clock helpsto transfer the signal so that it reaches the receiver on time at the required level. So the decodingis done to the correct bit by the voltage level.There is no coordination and synchronization among the transmitting bits about the timing ofthe individual bits. To represent a certain level and to represent a single bit there is nounderstanding of how long the transmitter leaves the digital bit. To understand the start and endof the signal during the transmission bit helps us understand the synchronization of the bits.Analog and digitalWave like phenomenon of analog waves is used by the analog systems. By stayinganalog all the way these waves are not converted to any other form and stay analog. In analogsystems, analog signals like audio or video (in most cases, the human voice) are translated intoelectronic pulses. Old systems like POTS use analog signal to transfer voice from one end toanother.Digital systems use the concept of 1s and 0s like on and off. With the help of samplingthe digital systems use analog waves and con
