A dyad is a group or pair consisting of two elements or individuals. In various fields, such as psychology and sociology, dyads are often studied to understand relationships, interactions, and dynamics between two people. For example, a friendship or a couple can be considered a dyad, as they involve direct communication and influence between the two members. In mathematics, a dyad can refer to a pair of elements in a set or a two-dimensional vector. Dyads are also used in computer science to represent binary relationships, such as connections in a graph or data structures. Overall, the concept of a dyad is fundamental in analyzing relationships across different disciplines.
