Answer:
"Waterfall" is the correct answer for the above question.
Explanation:
- The Waterfall model is a model which is the first model recognized by some scientists is used to states some rules to develop the software. It is based on the phases of the SDLC. The SDLC is the collection of phase that is used in software development.
- The waterfall model moves like water moves. It means any next phase starts if the previous phase is completed and the user can not move into previous steps of the model.
- This is also asked by the question. Hence the answer is the waterfall model.
Answer:
Answer is b. 10
Explanation:
The find() method is used to search the string for a specified value and searches the first occurrence of that value. It returns the position of that specified value. If the value is not found, this method returns -1.
Lets say we have a message variable that contains the string Happy holidays.
message = "Happy holidays"
We use the method find() to find days word from the Happy holidays string in the message variable.
The find() method will find the position of day.
If we look at the string Happy holidays we see that the word day is at the 10th position of the string.
H 1
a 2
p 3
p 4
y 5
h 6
o 7
l 8
i 9
d 10
a 11
y 12
s 13
So it is at 10th position so the statement
message.find("days")
returns 10
Answer:
D.
Explanation:
In combinational circuits, the current output values are always the same for the same set of input values, regardless the previous values.
We say that combinational circuits have no memory, or that the circuit has no feedback from the outputs.
For sequential circuits, on the contrary, the current output values are not based in the current input values only, but on the previous output values as well.
So, the fact of having a defined set of input values at a given moment, doesn't guarantee which the output values will be.
We say that sequential circuits have memory, or that they have feedback from the outputs.
Examples of these type of circuits are R-S, J-K, D or T flip-flops.

Time-to-live or TTL <span>tells a server how long the record should remain in the cache.
TTL is a mechanism that limits the lifetime of data in a network or a computer and prevents data packets from circulating indefinitely.
