What is a dumb terminal?
A dumb terminal is a terminal that does not performing local processing of entered information, but serves only as an input/output device for an attached or network-linked processor.
What is example of dumb terminal?
For example: “A display monitor that has no processing capabilities. yeah A dumb terminal is simply an output device that accepts data from the CPU. In contrast, a smart terminal is a monitor that has its own processor for special features, such as bold and blinking characters.
Why is it called a dumb terminal?
The industry began to call these devices “dumb terminals” because they usually did not contain the capabilities of a general purpose computer (however, many terminals of the 1980s did contain special-purpose software and were far smarter than the “dumb” name implies).
What is a dumb terminal and an intelligent terminal?
Webopedia Staff. A terminal (monitor and keyboard) that contains processing power. Intelligent terminals include memory and a processor to perform special display operations. In contrast, a dumb terminal has no processing capabilities; it must rely entirely on the central computer.
What is a common use of dumb terminals?
Dumb terminals are those that can interpret a limited number of control codes (CR, LF, etc.) but do not have the ability to process special escape sequences that perform functions such as clearing a line, clearing the screen, or controlling cursor position.
What is intelligent terminal?
A terminal with built-in processing capability, but no local disk or tape storage. It may use a general-purpose CPU or may have specialized circuitry as part of a distributed intelligence system. Contrast with dumb terminal.
What are mainframe dumb terminals?
These dumb terminals were low-cost devices that usually consisted of a monitor, keyboard and a communication port to talk to the mainframe. Initially these terminals were hard wired directly to communication ports on the mainframe and the communications were asynchronous.
What is meant by a dumb terminal What are its main advantages?
A dumb terminal is a very simple monitor with very little processing power and features. It does not have the ability to process escape sequences such as clearing a line, clearing the screen or controlling the cursor position. It is dubbed as a glass Teletype as it has the same limited functionality of one.
What is an example of intelligent terminal?
The device is often a combination of a display and keyboard with at least one built-in microprocessor to provide facilities such as editing and prompts for the operator. Modern application terminals for banking, retail, and industrial data collection are other examples of intelligent terminals.
What is mainframe model?
The mainframe model consists of centralized computers, usually housed in secure climate-controlled computer rooms. End users interfaced with the computers via ‘dumb terminals’. These dumb terminals were low-cost devices that usually consisted of a monitor, keyboard and a communication port to talk to the mainframe.
