2.	What Is The Difference Between Photodiode And Solar Cell?
Answer» A photodiode is made to detect light quickly a solar cell is made to COLLECT energy from light. They are both typically silicon diodes, but modified to meet their different requirements. A photodiode has to be fast, which means low capacitance, which means small area of silicon. THEREFORE, it is not very sensitive, and cannot generate much POWER from light. A solar cell has as large an area as you can afford to buy, GETTING WATTS per square inch. There are other differences in the way they are made, and how the PN junction is grown, but they all relate to this difference in purpose.

3.	Different Types Of Communications? Explain.?
Answer» Analog and digital COMMUNICATION. As a technology, analog is the process of taking an audio or video signal (the human voice) and translating it into electronic pulses. Digital on the other hand is BREAKING the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s. Digital SIGNALS are immune to NOISE, quality of transmission and reception is good, components used in digital communication can be produced with high precision and power consumption is ALSO very less when compared with analog signals.
