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.
One advantage of Binary Search Algorithm:
Compared to Linear search it is much faster because linear search starts its searching right from the first value but binary searches for something by splitting the array in two again and again and again.
One disadvantage of Binary Search Algorithm:
Have to be sorted, unlike linear search that doesn't have to be.
A...........................................
To convert binary fraction to decimal fraction, we first write the given
.1011 (base 2)
The process of conversion is to break down to its decimal constituent,
.1011 (base 2) = (1*2^-1)+(0*2^-2)+(1*2^-3)+(1*2^-4)
.1011 (base 2) = 0.5 + 0 + 0.125 + 0.0625
.1011 (base 2) = 0.6875 (base 10)
<em>ANSWER: 0.6875 (base 10)</em>
