Transmission Delay
Data is an essential part of network communication. To effectively transmit data through all kinds of networks, it must be streamlined into smaller data packets. Instead of sending a whole file to the other side, these variably-sized packets are sent across the network path to reduce transmission latency. Once they reach their destination, these packets are reconstructed into a complete file. This process is called packet-switching.
Coding Theory
Code is an alternative representation of some information—like a word, image, sound, and so on—that follows a set of rules. While coding theory may refer to the practice of studying such codes and their applications, in recent years, the term pertains to error-correcting codes.
