Which one is NOT a function of the physical layer: @Provides the physical connection between sender and receiver. Converting digital bits into electrical signal Specifies data rate (number of bits sent each second) Ensures complete and reliable delivery of data packets
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.
