Material that has been cut or copied from a document is placed on a virtual clipboard from which it can be pasted into a document in another program is true.
(A) material that has been cut or copied from a document is placed on a virtual clipboard from which it can be pasted into a document in another program.
<u>Explanation:</u>
In computer or laptop or desktop, cutting or coping or moving and pasting images or files is done as normal operation in computer.
Virtual clipboard is used for copy or moving or cutting of media files or document or images.
Short keys are available in windows operating system to do copy or select all or cutting or pasting.

Virtual clipboard can be syncing with their Hotmail account also.
Framing in photography is one way of covering the other parts of the subject. Framing gives the photo some context, depth and layers and make the image as the main focal point.
Answer:
a) only one digit changes as the number increases.
Explanation:
Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)
consider the 4 bit representation of Binary coded decimal and RB codes
Decimal | Binary code | Reflected binary (RB) code
0 0000 0000
1 0001 0001
2 0010 0011
3 0011 0010
4 0100 0110
5 0101 0111
As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.
But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.
The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.
The RB code is widely used in linear and rotary encoders, error correction and digital logic design.
