What device converts ordinary alpha/numeric information to binary?

An encoder is a device that transforms ordinary alphanumeric information into binary form. This transformation is essential in digital systems where data needs to be represented in a format that computers and processors can understand and manipulate.

Encoders take input data and produce a binary code that uniquely represents the input. For instance, in the context of a keyboard, pressing a key generates a specific binary code through an encoder, which is then processed by the computer.

This function is crucial in various electronic systems where alphanumeric data is used for processing and communication. This encoding process enables efficient data management and is foundational in digital electronics, making the encoder a vital component in modern electronics.
