The computer that processes both analog and digital data is called a Hybrid computer. These specialized machines combine the best features of both analog and digital computers, allowing them to handle continuous physical quantities (like temperature or pressure) and discrete numerical data simultaneously. They are often used in complex scientific and industrial applications where real-time processing of varied data types is crucial.

An Analog computer processes continuous data, while a Digital computer processes discrete data (binary 0s and 1s). A Mainframe computer is a large, powerful digital computer primarily for high-volume data processing, not defined by its ability to process both analog and digital signals.
