Answer:
performance -processor speeds increases because the smaller the transistor, the faster it can operate. Additionally, the transistors become closer to each other which reduces the latency between them.
2.Complexity-for a given size the number of transistors doubles with the reduction in feature size
Explanation:
Answer:
No you can not tell that recursion is ever required to solve a problem.
Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.
Iteration is also another form of repetitive approach we follow to solve that kind of problems.
But the difference between recursion and iteration is :
- In recursion we call the function repeatedly to return the result to next level.
- In iteration certain bunch of instructions in a loop are executed until certain conditions met.
Explanation:
For example in the Fibonacci sequence problem, to find 
, we need to compute 
and 
before that.
- In case of recursion we just call the method Fibonacci(n) repeatedly only changing the parameter Fibonacci(n-1), that calculates the value and return it.
Fibonacci(n)
1. if(n==0 or n==1)
2. return 1.
3.else
4. return( Fibonacci(n-1)+Fibonacci(n-1) )
- But in case of iteration we run a loop for i=2 to n, within which we add the value of current
and 
to find the value of 
Fibonacci(n)
1. if(n<=2)
2. result = 1
3. else
4. result1 =1 and result2=1.
5. { result = result1 +result2.
6. result1= result2.
7. result2 = result.
8. }
9. output result.
The best thing to do when an error message appears when it is not supposed to, as in if you are blocked by an administrator and it appears then its supposed to, it is best to contact someone who can investigate whether or not something is happening to your computer. That could be a parent, if they are good with computers, or just tech support at a store, provided they also know computers. Most of the time your computer just makes a mistake so nothing to worry about, but make sure to have it checked just to be sure.
Answer: To reuse a method means to use a code which has been done or prepared already and just we need to change some of the functionalities.
This helps a great deal of saving time as well as helps in making the code manageable.
Explanation:
This has been practiced since long that methods can be reused. for example we need to build a calculator in c. then we can simply reuse the same method just we need to change the sign of the operator. So in this process we can speed up our operations and work and also can make the code easy to understand and manage it when we have have to deal with large lines of code.
