Which of the following parameters is optional sample(a,b,c,d=7

Answer:

SELECT

CardNumber,

len(CardNumber) as CardNumberLength,

right(CardNumber, 4) as LastFourDigits,

'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber

from Orders

Explanation:

The question you posted contains the answer (See answer section). So, I will only help in providing an explanation

Given

Table name: Orders

Records to select: CardNumber, length of CardNumber, last 4 digits of CardNumber

From the question, we understand that the last four digits should display the first 12 digits as X while the last 4 digits are displayed.

So, the solution is as follows:

SELECT ----> This implies that the query is to perform a select operation

CardNumber, ---> This represents a column to read

len(CardNumber) as CardNumberLength, -----> len(CardNumber) means that the length of card number is to be calculated.

as CardNumberLength implies that an CardNumberLength is used as an alias to represent the calculated length

right(CardNumber, 4) as LastFourDigits, --> This reads the 4 rightmost digit of column CardNumber

'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber --> This concatenates the prefix XXXX-XXXX-XXXX to the 4 rightmost digit of column CardNumber

as FormattedNumber implies that an FormattedNumber is used as an alias to represent record

from Orders --> This represents the table where the record is being read.

Answer:

Optical storage devices.

Explanation:

Optical storage device are those devices that read and store data using laser. To store data in optical storage devices low-power laser beams are used. It is a type of storage that stores data in an optical readability medium.

Examples of the optical storage device includes Compact disc (CD) and DVD.

The optical storage device is popular in storing data of music, videos, and computer program. Therefore, the optical storage device is the correct  answer.

Answer:

a. 100.

b. 31500.

Explanation:

So, we are given the following data which is going to help in solving this particular question.

The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.

Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.

The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.

The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.

Assuming U = 1.

Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.

=0.667 + 15.083.

= 15.75 millisecond.

Average number of instruction = 15.75/0.0005 = 31500.

It should be noted that the number of pages in a second will be 100 pages.

From the information given, it was stated that the instruction takes 1/2 microsecond to execute and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read the page.

Therefore, the execution time will be:

= 0.5/1000

= 0.0005

Therefore, the number of pages will be:

= 1000/10

= 100

Also, the disc transfer time will be;

= (2/3 × 1) + (1/3 × 0.25 + 15) × 2

= 0.667 + 15.083

= 15.75

Therefore, the average number of instructions will be:

= 15.75/0.0005

= 31500

Answer:

They are set up manually

Explanation:

BGP neighbor relationships formed "They are set up manually."

This is explained between when the BGP developed a close to a neighbor with other BGP routers, the BGP neighbor is then fully made manually with the help of TCP port 179 to connect and form the relationship between the BGP neighbor, this is then followed up through the interaction of any routing data between them.

For BGP neighbors relationship to become established it succeeds through various phases, which are:

1. Idle

def simulate_visited_area_codes():

   area_codes = []

   for i in range(51):

       num = random.randint(200,1000)

       area_codes.append(num)

   visited_codes = [289, 657, 786, 540]

   count = 0

           if area_codes[i] == visited_codes[j]:

               count+=1

   return count

print("Visited Areas: "+str(simulate_visited_area_codes()))

Explanation:

So many incomplete details in your question, so I will fill in the gap (i.e. make assumptions)

The assumptions are:

The program and explanation is as follows: (comments are written in bold)

#This imports the random module

import random

#This defines the function

def simulate_visited_area_codes():

#Thie initializes area_codes to an empty list

   area_codes = []

#This iterates from 1 to 50 and generate 50 random numbers to the area_codes list

   for i in range(51):

       num = random.randint(200,1000)

       area_codes.append(num)

#This initializes the visited_code

   visited_codes = [289, 657, 786, 540]

#This initializes count variable to 0

   count = 0

#This iterates through the list and looks for matching code between the area_code and the visited_code lists

   for i in range(51):

       for j in range(len(visited_codes)):

           if area_codes[i] == visited_codes[j]:

#The count variable is incremented by 1 for matching codes

               count+=1

#This returns the count

   return count

#The main begins here and prints the number of area code visited

print("Visited Areas: "+str(simulate_visited_area_codes()))

Explanation:

In this code, two integer variable "squirrels and walnuts" and one bool variable "result" is declared, in which the integer variable use that input the value from the user-end, and inside this the multiple conditional statements is used that checks integer variable value and use the bool variable to assign value as per given condition and at the last, it uses if block to check the bool variable value and print its value.

Explanation:

The following code is very long and is split into the 4 classes that were requested/mentioned in the question: Department, Employee, Address, and Test. Each one is its own object with its own constructor. Getters and Setters were not created since they were not requested and the constructor handles all of the variable creation. Address makes apartment variable optional by overloading the constructor with a new one if no argument is passed upon creation.

package sample;

import sample.Employee;

import java.util.ArrayList;

class Department {

   String name = "";

   double budget = 0;

   ArrayList<Employee> employees = new ArrayList<>();

   void Department(String name, double budget, ArrayList<Employee> employees) {

       this.name = name;

       this.budget = budget;

       this.employees = employees;

   }

}

package sample;

public class Employee {

   String FirstName, LastName;

   Address address = new Address();

   public void Employee(String FirstName, String LastName, Address address) {

       this.FirstName = FirstName;

       this.LastName = LastName;

       this.address = address;

   }

}

-------------------------------------------------------------------------------------------------------------

package sample;

class Address {

   String Street, City;

   int apartment;

   char[] state;

   public void Address(String street, String city, char[] state, int apartment) {

       this.Street = street;

       this.City = city;

   public void Address(String street, String city, char[] state) {

       this.Street = street;

       this.City = city;

       this.state = state;

       this.apartment = 0;

   }

}
