In half-duplex communication between two hosts, both hosts can transmit, and both hosts can receive, but hosts cannot transmit and receive simultaneously.

a) True b) False

Answers

Answer 1

Answer:

True: In half Duplex communication both of the hosts can transmit and receive. But can not do both job simultaneously.

when one host is sending other one can receive but can not transmit. And the receiving host waits for the transmitting host to finish transmitting, before it starts transmitting from it's end.

When one host is receiving other one can transmit.

For example- The communication system of army people. when one person talks the person in the other end has to wait till he finishes. They can not talk simultaneously.

Explanation:

Where in full duplex the both hosts can transmit and receive simultaneously, in half duplex system that's not possible.

The ____ method takes a String argument and returns its double value.

a.
parseString()

b.
returnDouble()

c.
parseInt()

d.
parseDouble()

Answers

Answer:

d

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.

: Differentiate between serial and parallel data transfer withat least one example of each from computer sciencedomain.

Answers

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.

Given a int variable named callsReceived and another int variable named operatorsOnCall write the necessary code to read values into callsReceived and operatorsOnCall and print out the number of calls received per operator (integer division with truncation will do).

Answers

// 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:

# Read the number of calls received and the number of operators on call
callsReceived = int(input('Enter the number of calls received: '))
operatorsOnCall = int(input('Enter the number of operators on call: '))

# Calculate the calls per operator with integer division
callsPerOperator = callsReceived // operatorsOnCall

# Print the result
print('The number of calls received per operator is:', callsPerOperator)

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

A jeweler designing a pin has decided to use five stones chosen from diamonds, rubies, and emeralds. In how many ways can the stones be selected?

Answers

Answer:

3,125 different possible ways

Explanation:

Great question, hopefully i can shed some light on the situation. There are a total of 5 stones. One by one they are randomly picked out of the bag. We need to find how many possible combinations there are for picking the stones out of the bag. We can solve this by raising the amount of stones in the bag to its own power like so,

[tex]5^{5} =  3,125[/tex]

So now we can see there are 3,125 different possible ways of selecting the stones.

write a program that convert binary number to decimal. I mean the input should be binary number and the output decimal number!!.

Answers

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.

True / False
The exponent in floating point is stored as a biased value.

Answers

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.

Write a Java program that calculates and prints the monthly pay check for an employee. The net pay is calculated after taking the following deductions:

Federal Income Tax: 15%
State Tax: 3.5%
Social Security Tax: 5.75%
Medicare/Medicaid Tax: 2.75%
Pension Plan: 5%
Health Insurance: $75.00

Answers

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.

When askingfor a raise, which one among the following is important toremember?

b- Non-cash benefits may beof value if a raise is not feasible

c- The length of employmentis a great bargaining tool in asking for araise

d- Emotional appeals canhelp in getting a positive response to therequest

Answers

Answer:

a-Effort is to be rewarded

Explanation:

When you ask for a raise in an organization,the one of the most important thing is Effort.There is a reason for everything in organization,if you are asking to raise your income organization will ask you on which basis you are asking.If you put extra hours than before or you gain some skill which is useful for the organization,so while asking for raise you should know the effort that you put in because effort is most important factor for a raise.

In formal organizations, Non cash benefits are not there so there is no purpose for asking it.

Employment does not matter for the peer in asking for a raise,sometimes it is used by small organizations but it is informal,the one should focus more on effort rather than the employment.

Emotional appeals may help in informal organization,never in formal organization.It only imprints negative image on peer's mind,if you want to have a raise you should focus on Effort.
