Write shorl notes on each of the following:i. Attenuation.ii. As.vnchronous lransmission.

i. Attenuation: Attenuation refers to the decrease in the strength or intensity of a signal as it travels through a medium or transmission path. It is commonly encountered in telecommunications and networking systems. Attenuation can be caused by factors such as distance, interference, and the characteristics of the medium itself. The goal is to minimize attenuation to ensure reliable and high-quality signal transmission.

ii. Asynchronous transmission: Asynchronous transmission is a method of data transmission where individual characters or data units are sent one at a time, with each character being preceded by a start bit and followed by one or more stop bits. This type of transmission does not require a constant clock signal to synchronize the sender and receiver. Asynchronous transmission is commonly used in serial communication protocols and is suitable for transmitting small amounts of data over relatively long distances.
