Название: 29.Information Theory
Автор: Webster J.
In computers and digital communication systems, information is almost always represented in a binary form as a sequence of bits each having the values 0 or 1. This sequence of
bits is transmitted over a channel from a sender to a receiver.
In some applications the channel is a storage medium like a
CD, where the information is written to the medium at a certain time and retrieved at a later time. Due to physical limitations of the channel, some of the transmitted bits may be corrupted (the channel is noisy) and thus make it difficult for the
receiver to reconstruct the information correctly.
