What are the differences between a dumb terminal and an intelligent terminal?

A dumb terminal is a simple device that relies on a central computer for processing and has no computational capabilities of its own; it primarily serves as an input/output interface. In contrast, an intelligent terminal has its own processing power and can perform tasks such as data manipulation or local computations, allowing it to operate independently to some extent. Additionally, intelligent terminals often support more complex user interfaces and can run applications locally, whereas dumb terminals are limited to displaying data and sending commands to the central system.
