A remote terminal is a device used to access a computer system from a location other than where the system is physically located. There are various synonyms for remote terminals, including thin clients, dumb terminals, network terminals, virtual terminals, and cloud terminals. Thin clients are lightweight devices that rely on a server for processing, while dumb terminals are terminals without processing capabilities. Network terminals, on the other hand, are connected to a network to access a central server. Virtual terminals provide remote access to virtual machines, and cloud terminals are cloud-based computing platforms that allow access to applications and services from anywhere. Each of these synonyms has its own unique features and benefits, depending on the use case.
