Answer:
a tactile input device
Explanation:
Based on the scenario being described it can be said that the best assistive technology for Bernard would be a tactile input device. Such a device would allow Bernard to physically interact with the print on the chalkboard or overhead screen from the device itself without having to actually get close to the chalkboard or screen. Thus allowing him to view its content from the palm of his hand.

The answer is user EXEC mode. This is for setting, viewing, and testing system processes. In common, the user EXEC commands let you to link to remote devices, modify terminal line settings on a temporary basis, perform basic tests, and list system information. This also used by common system administrators, while the privileged EXEC mode is used by the root administrator. Use the enable and disable instructions to shift between the two levels. Access to the user-level EXEC command line needs a valid password.
