Binary coding

Definition

Binary coding is a method of representing data using two distinct states, typically denoted as 0 and 1. This representation is essential in character-based methods where biological sequences are transformed into a binary format for computational analysis. By converting characters or nucleotide sequences into binary form, it allows for efficient storage, retrieval, and processing of genetic information in bioinformatics.
