OSI and TCP/IP Models

a) Suppose you are going to transmit a packet over OSI Network Model. Explain the working of Router, Gateway and Switch. Which device will be used if you face an issue of weak signals during transmission? Also, Mention on which level of OSI model these devices will work efficiently.

b) Attenuation, Distortion and Noise are the causes of Transmission impairment. What would be the solution or how these causes can be improved.
