You have developed a prototype of a software system and your manager is very impressed by it. She proposes that it should be put

into use as a production system, with new features added as required. This avoids the expense of system development and makes the system immediately useful. Write a short report for your manager explaining why prototype systems should not normally be used as production systems.

Answer:

Explanation:

Talking about prototype model, we can say that, it is developed by knowing the requirments.

A client Interaction with prototype makes the client to have the ability to get the feel of system.

It is best for large systems as this helps to determine the requirements. It is not complete, this is because many of its details are yet to be built. Users also involved in its development.

Production system is a result of organizing inputs, then process is carried out and then output is based on some logic and functions. Production system fails if any such arrangement made don't give a desired level of outcome.

If requirments are missed then prodution system may fail. So prototype systems are not used as production systems.

You have an on-premises network that contains several servers. You plan to migrate all the servers to Azure. You need to recomme
Ainat [17]

Answer:

A). Fault tolerance

Explanation:

The Microsoft Azure is described as the cloud computing service that is known for its flexibility, cost-effectiveness, and quick and easy compliance to fulfill the company's requirements.

As per the question, in order to ensure that 'some servers are available in case of a single Azure data center going offline for an increased time period', the recommendation must include the 'fault tolerance' ability of Azure services. Azure infrastructure has the ability to immediately react in case of a failure to restore the servers and its services. In case of hardware failure, crashing of hard-disks, or short-term availability problems with servers, Azure predicts and manages such failures effectively. Thus, <u>option A</u> is the correct answer.

The elements of an integer-valued array can be set to 0 (i.e., the array can be cleared) recursively as follows: An array of siz
dangina [55]

Answer:

The method definition to this question can be given as:

Method definition:

public void clear(int[] arr, int num) //define method clear.

{

   if (num == 0) //if block

{

       return 0;  return value.

}

else //else block

{

 arr[num - 1] = 0; //assign value in arr.

return arr[];  //return value.

}

}

clear(arr, num - 1);   //calling

Explanation:

The description of the above method definition as follows:

  • Firstly we define a method that is "clear" that does not return any value because its return type is "void". This method accepts two integer variables that are "arr[] and num" where arr[] is an array variable and num is an integer variable.
  • Inside a method, we use a conditional statement in if block we check that num variable value is equal to 0. if this condition is true so, it will return 0 otherwise it will go to else block in else block it will assign value in variable arr[num-1] that is "0" and return arr value.

Which of the following statements is true? A. Interpreted programs run faster than compiled programs. B. Compilers translate hig
alina1380 [7]

Answer:

B.

Explanation:

Computer programs are written in high level languages. Every language has its own set of syntax and semantics.

Computer only understands instructions in machine language which is written using strings of 0 and 1.

Thus, for execution of a high level language program, it is mandatory to convert high level instructions into machine instructions.

This translation into machine language is done in two ways – compilation or interpretation.

Some languages are compiled while others are interpreted.

Both compilers and interpreters are programs and process the high level language program as needed.

Compiler

Any program written in high level language is compiled.

The program is first analyzed before compilation. This process takes time. The analysis phase is called pre processing.

The program compilation stops only when the program is completely analyzed. Hence, it is difficult to locate the error in the program. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

A compiler is responsible for converting high level language code into machine level code.

The complete program undergoes compilation at the same time.

A compiled program executes faster than an interpreted program.

A compiled program produce machine code which is a collection of 0 and 1, hence, it takes less time to execute.

Examples of compiled languages are C and C++.

Interpreter

Some high level languages are interpreted.

The high level language code is translated into an intermediate level code. This intermediate code is then executed.

The analysis of the program takes less time and takes place before interpretation begins. The analysis phase is called pre processing.

An interpreted program is translated one line at a time.

The program interpretation stops when an error is encountered. This makes debugging easy.

Debugging is defined as removal of errors in the programs.

Examples of interpreted languages include Python and Ruby.

In a Diffie-Hellman Key Exchange, Alice and Bob have chosen prime value q = 19 and primitive root a = 10. If Alice's secret key
34kurt

Answer:

a) 6

b) 11

c) 11

Explanation:

Given

Prime value q =n= 19

primitive root (a) =10

Alice secret key = 4

Bob secret key = 6

a) The value Alice Sends to Bob

a​​​​​Private key of Alice mod n

= 10^4 mod 19

= 10000 mod 19

=6

b)The value Bob sends to Alice

a​​​​​Private key of Bob mod n

= a​​​​​​3​​​​​ mod n

= 10^6 mod 19

=1000000 mod 19

= 11

c)

Both the parties calculate the value of secret key at their respective side.

secret key obtained by Alice

= 11

secret key obtained by Bob

= 11

Finally, both the parties obtain the same value of secret key.

The value of common secret key = 17
