Difference Between Diffraction and Interference

The crucial difference between diffraction and interference is that diffraction of light occurs due to the superposition of secondary wavelets that generates from various parts of a wavefront (simply put spreading of light when the beam passes through the slit). As against interference is the result of the superposition of light waves from 2 coherent…

Difference Between Serial and Parallel Communication

The crucial difference between serial and parallel communication is that in serial communication a single communication link is used to transfer the data from an end to another. As against in parallel communication, multiple parallel links are used that transmits each bit of data simultaneously. Due to only a single communication link serial communication is…

Difference Between Potentiometer and Rheostat

The crucial difference between potentiometer and rheostat is that a potentiometer is used to determine the unknown emf thus controls the circuit voltage. As against a rheostat is an instrument that controls the flow of current through a circuit. The potentiometer measures the unknown emf or voltage by making a comparison with a known voltage.…

Difference Between Diode and Thyristor

One of the crucial difference between diode and thyristor is that a diode is a two terminal device used for rectification and switching applications. As against a thyristor is a three terminal device used for switching purpose. This generates the major difference in their operation. We know both diode and thyristor are semiconductor devices formed…

Difference Between Star and Ring Topology

One major difference between star and ring topology is that in star topology the devices in the network are interconnected through a central hub. While in ring topology each device of the network is connected to its adjacent device present in the network. We know that topology refers to the way in which multiple devices…

Difference Between FDM and TDM

FDM and TDM are the two types of multiplexing technique that allows simultaneous transmission of multiple signals over only one channel. One of the major difference between FDM and TDM is that in FDM, multiple signals are transmitted by occupying different frequency slots. As against in TDM, the various signal gets transmitted in multiple time…

Difference Between Active and Passive Filter

The major difference between active and passive filter is that an active filter uses active components like transistor and op-amp for the filtering of electronic signals. As against, a passive filter uses passive components like resistor, inductor and capacitor to generate a signal of a particular band. Another major difference between the two is that…

Difference Between Optical fiber and Coaxial Cable

Both optical fiber and coaxial cable are the types of guided media. But some major factors exist that differentiates the two. The crucial difference between optical fiber and coaxial cable is that an optical fiber is used for the transmission of the optical signal. As against, a coaxial cable is used for the transmission of…

Difference Between Transducer & Inverse Transducer

One of the major difference between the transducer and the inverse transducer is that the transducer changes the non-electrical quantity into an electrical quantity while the inverse transducer changes the electrical quantity into the non-electrical quantity. The other differences between the transducer and inverse transducer are shown below in the comparison chart. The control action…
