Answer:

Charles Babbage (1791-1871), computer pioneer, designed two classes of engine, Difference Engines, and Analytical Engines. Difference engines are so called because of the mathematical principle on which they are based, namely, the method of finite differences.

Windows workstations all have elements of server software built-in. What are these elements, and why is the Windows Professional
lions [1.4K]

Answer:

The answer is below

Explanation:

Elements of Server software that is built-in, in Windows workstations are:

1. Hard drives,

2. RAM (Random Access Memory)

3. Processors

4. Network adapters.

Windows Professional OS is not considered a server due to the following:

1. Windows Professional OS has a limit on the number of client connections it allowed.

2. Unlike Server, Professional OS uses less memory

2. In comparison to Server, Professional OS uses the CPU less efficiently

4. Professional OS is not built to process background tasks, unlike Server that is configured to perform background tasks.

Which part of project management involves determining the overall work? Breakdown Incomes Scope Time
Oliga [24]

Answer:

Incomes

Explanation:

Project management has to do with the process of achieving a set goal with the help of a team within a specified time. Most times, the main problem that comes with project management is completing the project within the available constraints.

No project can start up without funds, which in this case is called income and this is the part of the project that determines the overall work.

"Write an iterative function iterPower(base, exp) that calculates the exponential baseexp by simply using successive multiplicat
sp2606 [1]

Answer:

I am writing the function using Python. Let me know if you want the program in some other programming language.            

def iterPower(base, exp):    

    baseexp = 1

    while exp > 0:

        baseexp = baseexp*base

        exp= exp - 1

    return baseexp

base = 3

exp = 2

print(iterPower(base, exp))

Explanation:

  • The function name is iterPower which takes two parameters base and exp. base variable here is the number which is being multiplied and this number is multiplied exponential times which is specified in exp variable.
  • baseexp is a variable that stores the result and then returns the result of successive multiplication.
  • while loop body keeps executing until the value of exp is greater than 0. So it will keep doing successive multiplication of the base, exp times until value of exp becomes 0.
  • The baseexp keeps storing the multiplication of the base and exp keeps decrements by 1 at each iteration until it becomes 0 which will break the loop and the result of successive multiplication stored in baseexp will be displayed in the output.
  • Here we gave the value of 3 to base and 2 to exp and then print(iterPower(base, exp)) statement calls the iterPower function which calculates the exponential of these given values.
  • Lets see how each iteration works:
  • 1st iteration

baseexp = 1

exp>0 True because exp=2 which is greater than 0

baseexp = baseexp*base

               = 1*3 = 3

So baseexp = 3

exp = exp - 1

      = 2 - 1 = 1    

exp = 1

  • 2nd iteration

baseexp = 3

exp>0 True because exp=1 which is greater than 0

baseexp = baseexp*base

               = 3*3 = 9

So baseexp = 9

exp = exp - 1

      = 1-1 = 0    

exp = 0

  • Here the loop will break now when it reaches third iteration because value of exp is 0 and the loop condition evaluates to false now.
  • return baseexp statement will return the value stored in baseexp which is 9
  • So the output of the above program is 9.

Read "Penetration Testing – Reconnaissance with NMAP Tool," located within the required readings. In the article, the authors di
steposvetlana [31]

Answer:

Check the explanation

Explanation:

The two tools that are utilized for consideration in cyber attacks are operating systems and computer systems. The operating system Kali Linux 2.6 3.x Mix (64-bi) and windows XP SPO (32-bit).

Penetration testing is a very important technique or procedure in auditing the loopholes and security in a particular operating system. The computer systems are Nmap and VMware. The author posit that VMware is a virtual machines programming that gives a virtual PC the capacity for more than one event or action of the working frameworks to keep cunning one similar server.

Nmap (“Network Mapper”) according to the authors, it is a free and open source utility for system reviewing and security. these tools are used for the purpose of finding an open port and to also gain access while another considers the vulnerabilities of the operating system.

ALL together these tools assist in building the foundation for ethical hacking. Using Nmap allows a hacker to gain access to the system thereby seeing all the flaws to actively peruse that account. All these tools work together for a successful hacking process and procedures.
