Answer:
Interoperability is the ability of or degree to which two or more systems usefully exchange information via interfaces in particular context. Interoperability can be defined in two ways which includes the ability to exchange data (syntactic interoperability) and also the ability to correctly interpret the data being exchanged (semantic interoperability).
If two systems failed to exchange information properly, it means they are not clear to interpret and not easy to communicate and get proper information from each other and that might result in a failed communication which is in turn result in security flaw. 
Other quality attributes strongly related (at least potentially) to interoperability is Application Programming Interface (API)
API is a software intermediary that allows two applications to communicate to each other and are necessary for systems interoperability.
 
        
             
        
        
        
Since Joan wants to see what her presentation would look like in the eyes of her audience, it might be best for her to use the Slideshow view that is available at the bottom right side of her desktop view. 
This option is a full-screen form of her Normal view in Microsoft PowerPoint. The Slideshow view is represented by the projector screen symbol next to the zoom in and out bar.

Answer:
See below
Explanation:
Because sometimes you have to 'carry' a 1 over to the ext column when adding two binary numbers
Example :
  1 1 1
<u>+1 1 1 </u>    <==== starting in the first R column add  1 + 1  to get 0 and carry 1
                 then the next column you will add   1 + 1 + 1  = 1   and carry 1 again
                     then 1 + 1 + 1= 1  and carry 1 again (to column 4)  to get 
 1   1  1 0
