The correct answer is: B. speech processing capability
An intelligent I/O device is one that can understand and respond to human speech. This is in contrast to a non-intelligent I/O device, which can only accept and process data in a pre-defined format.
Speech processing capability is important for I/O devices because it allows users to interact with them in a more natural way. This can be especially helpful for users who have difficulty using traditional input methods, such as a keyboard or mouse.
Here is a brief explanation of each option:
- A. color output capability: This is a feature that allows an I/O device to produce output in color. While this can be a useful feature, it is not what makes an I/O device intelligent.
- B. speech processing capability: This is the ability of an I/O device to understand and respond to human speech. This is what makes an I/O device intelligent.
- C. high speed printing capability: This is the ability of an I/O device to print documents at a high speed. While this can be a useful feature, it is not what makes an I/O device intelligent.
- D. feature to support offline and online tasks: This is the ability of an I/O device to work both when it is connected to a network and when it is not. While this can be a useful feature, it is not what makes an I/O device intelligent.
- E. None of the above: None of the above options are what makes an I/O device intelligent.
