The digital packets are compressed into the set standard format and then routed over the Internet connection. These compressed digital standard packets absorb the noise on the way; consequently, the packets get transferred faster and deeper efficiently. While routing over the Internet, packets are in compliance with standard sign protocols. The packets are routed over the various paths; when they arrive at the destination, there is a re-conversion of the digital packets to analog signals. These information is converted using Digital-to- Analog Converter or DAC.
