Answer:b)Conversion plan.
Explanation:Conversion plan is type of plan in which the the technique is followed by converting the data from the present system to another system's hardware and software surroundings.
The technique follows three basic steps in the conversion plan is software installation plan, hardware installation plan and conversion of data. Thus the correct option is option(b).
Question:
Write a function that adds together all values from 0 to a given value and returns the final number. For example, if the given value is `4`, you would add 0 + 1 + 2 + 3 + 4
Answer:
In Python:
def add_to_value(n):
sum = 0
for i in range(n+1):
sum = sum + i
return sum
Explanation:
This line defines the function
def add_to_value(n):
This line initializes sum to 0
sum = 0
The following iteration adds from 0 to n
<em> for i in range(n+1):</em>
<em> sum = sum + i</em>
This line returns the calculated sum
return sum
Answer:
The concealment cipher.
Explanation:
A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.
The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.
Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.
