Write difference in the form of a table between Ping and TraceRoute command?

Answer:

credits = (credits < 0) ? 0 : credits;

Explanation:

This is the ternary conditional operator.

Answer:

void updateCredit(float credit){

if credit < 0.0

credit = 0.0;

}

Explanation:

I am going to write a C function for this.

The input is your credit value, and it has just a conditional to verify if it is not negative.

void updateCredit(float credit){

if credit < 0.0

credit = 0.0;

}

Answer: A method without body is called abstract method. A abstract method can be called from a non abstract  class or method provided it is inherited using a subclass.

Explanation:

An abstract method is a method which does not have a body, it just has opening and closing curly braces. A class having an abstract method is also declared as abstract class. We cannot make an object of the abstract class.

example : public abstract float multiply(float x, float y);

is an example of abstract method.

calling an abstract method from a non  abstract method is possible provided it is inherited by a non abstract subclass.

Final answer:

A Java program can calculate an employee's net pay by deducting federal, state, Social Security, Medicare/Medicaid taxes, pension plan contributions, and health insurance costs from the gross pay. The net pay is then output as the amount the employee would receive in their paycheck.

Explanation:

To calculate the net pay for an employee after deductions, we need to write a Java program that considers the following deductions: Federal Income Tax at 15%, State Tax at 3.5%, Social Security Tax at 5.75%, Medicare/Medicaid Tax at 2.75%, a pension plan deduction at 5%, and a fixed amount for health insurance at $75.00.

Here is a simple example of how this Java program might look:

public class PaycheckCalculator {
   public static void main(String[] args) {
       double grossPay = 5000; // Example gross pay
       double federalTax = grossPay * 0.15;
       double stateTax = grossPay * 0.035;
       double socialSecurityTax = grossPay * 0.0575;
       double medicareTax = grossPay * 0.0275;
       double pensionPlan = grossPay * 0.05;
       double healthInsurance = 75;

       double netPay = grossPay - (federalTax + stateTax + socialSecurityTax + medicareTax + pensionPlan + healthInsurance);

       System.out.println("Net pay: $" + netPay);
   }
}

This program calculates each of the deductions based on the gross pay, subtracts them from the gross pay, and prints out the resulting net pay.

Answer:

#include<iostream>

using namespace std;

int main(){

   int sum = 12+33;

   cout<<"The sum is: "<<sum<<endl;

}

Explanation:

First include the library iostream in c++ program for input/output.

Then, create the main function and declare the variable sum as integer type and store the sum of two given values.

After that, display the result store in the sum variable on the screen by using the instruction cout.

Answer: Option A) De facto standard

Non proprietary standard is also termed as de facto standard.

Explanation:  Non proprietary standard is also termed as de facto as when the proprietary standard such as window are widely used, then it becomes  de facto standard. When de facto standard is referring in terms of computers, it is an accepted application, design or language standard that is used in industry but not officially recognized.  

An example of de facto standard is paper clip ion used in e-mail to represent an attachment.

Explanation:

In java you can use pareDouble(string str) to convert the string into double.

for example if you have string like this.

string str  = [tex]"16.45" ;[/tex]

then you can use

double mydouble = Double.parseDouble(str);

print(mydouble); //it will print out 16.45

but if the string would not be able to be parsed into double then you will get an error.

Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .

Explanation: Hash codes is a numeric value which  is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.

If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.

Answer:

#include<iostream>

#include<math.h>

using namespace std;

//main function

int main(){

   //initialization

   long b1;

   int d1=0,count_pos=0;

//display the message

   cout<<"Enter the binary number: ";

   cin>>b1;  //store the value

   //loop for take the digit one by one

   while(b1!=0){

       int rem1 = b1%10;

       d1 = d1 + rem1*pow(2,count_pos);

       count_pos++;

       b1 = b1/10;

   }

   //display the output

   cout<<"The decimal number is: "<<d1<<endl;

}

Explanation:

Create the main function and initialize the variables. Then, display the message on the screen by using the instruction cout and then, store the input enter by the user into the variable. Here, the variable declares with type 'long' because of the size of the input.

After that, we take a while loop for splitting the binary number into the digits and then we can do the operation.

Let's understand how you can convert binary to decimal with an example:

let the binary number is 1001:

decimal number is [tex][tex]1*2^{3}+0*2^{2}+0*2^{1}+1*2^{0}=9[/tex][/tex]

we put the same algorithms in the code. split the number into digit and then multiply with n raised to the power of 2 here, n is the position of digit from left to right.

NOTE: Position starts from zero.

and then, add the values. this process continues until the number is not zero.

After that, display the output on the screen.

Answer: Cli(Clear interrupt flag ) and sti(set interrupt flag) instructions are used for clearing the flag and setting or enabling a flag respectively while hooking an interrupt.

Explanation: During the action of hooking an interrupt,there are certain interruptions while changing of real time interrupt vector and to avoid those interruptions two instructions are used that is cli ans sli. Cli is present for the clearing or disabling the interrupt flag and sti is used for setting or enabling a interrupt flag.

Answer:

True

Explanation:

The bias value present in a floating point number deals with the positiveness and negativeness of the exponent part for a floating point number.  The bias value for a floating point number is 127. It means that 127 is always needed to be added to the exponent part of any floating point number.

In a single precision floating point number, we need 8 bits to store the exponent. Rather than storing it as a signed two's complement number, it is easier to simply add 127 to the exponent (because the lowest value that can be in 8 bit signed is -127) and simply store it as an unsigned number. If the stored value is bigger than the bias then it would mean the value of the exponent is positive otherwise it is negative, but if they are equal then it is 0.

Explanation:

Fields: Fields represent data and should be a noun. It should begin with a lower case letter.

Instance variable: it is a variable defined in class but outside the constructor and the method. instance variables are created when an object is instantiated.

Object: An object is the basic unit of object oriented programming language.and represents the real life entities. An object consists of state behavior and properties.

Method: Method in a collection of statements that perform some specific task and return the result to the caller.

// c++ code to read the recieved calls

cout<< " Enter the calls recieved :";

cin>>callsRecieved;

cout<< " Enter operator on call : ";

cin>>operatorsOnCall;

// calculating the call per operator

calls_per_operator = callsRecieved/operatorsOnCall;

// printing the vaule.

cout<<" Calls recieved per operator are : " << calls_per_operator <<endl;

Final answer:

To find the number of calls received per operator, read inputs for callsReceived and operatorsOnCall, then divide callsReceived by operatorsOnCall using integer division and print the result.

Explanation:

To calculate the number of calls received per operator, you will first need to read values into the variables callsReceived and operatorsOnCall. You can do this using an input method appropriate for the programming language you're using (e.g., scanf in C, cin in C++, or input() in Python). Once you have these values, you perform the division of callsReceived by operatorsOnCall and print the result. Here is an example code snippet in Python:

Note that integer division with truncation is used (// in Python) to get an integer result.

Answer:

  see attachment

Explanation:

You have not specified the language, or the details of the I/O form or prompts. Here is a program that does that, written in Wolfram language (the language of Mathematica).

It prompts separately for student name and student score. The minimum score is presumed to be higher than -99999. If only one student name is entered, the second output is that score with no name listed. There is no error checking.

We have elected to keep a list only of the two two scores, and to sort that list again each time a new entry is made.

Answer:

In broadcast the message is transmitted from one to all , in uni cast we have one to one transmission and in multicast we have transmission from one to many.

Explanation:

If we take the example of a simple messaging application it will be clear. If a message is exchanged between one person to another, then it is uni casting. If a person sends a message to all the persons in his contact list then it is broadcasting and  if a person sends messages to select persons in his contact list then it is multi casting. In multi casting management of the group is required regarding who can receive messages which is not required in broadcasting.

Answer:

In serial communication transfers one bit of data at a time, while parallel communication transfers many bits of data at the same time. Serial communication transmits the data bits sequentially, while parallel communication transmits data bits simultaneously, allowing greater amounts of data to be transferred.

-Serial communication is the one used to communicate the Arduino with the Computer through the USB cable.

-An example of a parallel port is the printer port. The Parallel Port was only created and used in the printers interface and the computers.

Explanation:

In serial communication, each bit is sent by its own clock flank where conditions are defined after each byte, if it is synchronous or asynchronous. In parallel communication there is only one single clock flank where the information is sent where it is an advantage to use it where there are several input or output data.

Answer:

Cache memory is relatively small in size as compared to the main memory. The cache memory stores programs, variables which are frequently used by the processor.

Explanation:

The cache memory is placed very close to the processor so that the programs and variables can be accessed very quickly as and when required by the processor. The size of the cache memory is small and also cost more. There is also a secondary cache in many systems which enables to store more programs which cannot be store in the primary cache.

For example: content enclosed within <i> and </i> will be rendered in italicized format.Similarly content enclosed within <b> and </b> will be rendered in bold.

Answer:

TRUE

Explanation:

The array is allow to store the multiple values but with same data type.

It cannot store element with different data type.

For example:

int array[] = {1, 'b', 8.7, 9, 'z'}

the above is wrong way to declare the array.

the correct ways is:

int array[] = {1,2,3,4};

float array[] = {1.2, 3.4, 9.6};

we can store only same data type element in multiple tiles.

Answer: True

Explanation:

The Von Neumann model is based on the concept of stored program where both of the program and instruction data are stored in the same electronic memory. Though it is still used in many models but due to the Von Neumann bottleneck we have the introduction of the secondary memory.
