Answer:
D. output derived from key K3
Explanation:
The cyphertext = EK3( DK2(EK1(plain text)))
And from the above, it is quite clear that in the case of the triple DES, the plain text is first encrypted using key 1, and then it is decrypted using the key 2. Finally, it is encrypted using the key 3, and this results in the final encrypted content, and which is the ciphertext. Thus, this clarifies that the output derived from the key k3 is the actual ciphertext, and hence the correct option for the above question is as mentioned above.
Answer:
I can give you the perimeter "algorithm" but not the flowchart.
Here you go:
p = w * 4
p = perimiter,
w = width/height
4 = the amount of sides needed.
perimeter = width * 4
to include both width and height, we would instead use:
perimeter = 2(width+height)
This also works with rectangles ^
--------------------------------------------------------------------------
To find an area, it is just width * height. This is also compatible with rectangles.
Answer:
Random-Access Memory
Explanation:
used as a short-term memory for computers to place its data for easy access
Metadata is the other term for document properties. It is a data that describes another data. The word “meta” means “an underlying definition or description”. Traditionally, it was used in libraries as card catalogs. In digitals, metadata is also used to describe digital data.
