Dumb Terminal

Computer terminal Dumb terminal 1 The specific meaning of the term dumb terminal can vary depending on the context in which it is used.

Computer terminal Dumb terminal 1 This type of dumb terminal is still supported on modern Unix-like systems by setting the environment variable TERM to dumb

Computer terminal Dumb terminal 1 In the broader context that includes all forms of keyboard/screen computer communication devices, including personal computers, diskless workstations, network computers, thin clients, and X terminals, the term dumb terminal is sometimes used to refer to any type of traditional computer terminal that communicates serially over a RS-232 connection that does not locally process data or execute user programs.

Computer terminal Dumb terminal 1 The term dumb terminal sometimes also refers to public computer terminals that are limited to monochrome text-only capabilities, or to terminals that transmit each character as it is typed rather than waiting until it is polled by a host computer.

Dumb terminal 1 A terminal that depends on the host computer for its processing power is called a #Dumb terminal|dumb terminal or thin client

Dumb terminal - Dumb and Intelligent Terminals 1 From the introduction of the IBM 3270, and the VT100|DEC VT100 (1978), the user and programmer could notice significant advantages in VDU technology improvements, yet not all programmers used the features of the new terminals (backward- compatibility in the VT100 and later Televideo terminals, for example, with 'dumb terminals' allowed programmers to continue to use older software).

Dumb terminal - Dumb and Intelligent Terminals 1 Most terminals in the early 1980s, such as ADM-3A, TVI912, Data General D2, DEC VT52, despite the introduction of ANSI terminals in 1978, were essentially dumb terminals, although some of them (such as the later ADM and TVI models) did have a primitive block-send capability

Dumb terminal - Dumb and Intelligent Terminals 1 Around the mid 1980s intelligent terminals, costing less that most dumb terminals would have a few years earlier, could provide enough user-friendly local editing of data and send the completed form to the main computer
