​

Answer:

The answer is 2AF₁₆ = 687₁₀ =  1010101111₂.

Explanation:

To convert from hexadecimal base system to binary base system, first you can do an intermediate conversion from hexadecimal to decimal using this formula:

[tex]N = x_1 * 16^0 + x_2 * 16^1 + x_3 * 16^2 + x_4 * 16^3+ ... + x_n 16^n^-^1[/tex]

, where position of the x₁ is the rightmost digit of the number and:

2AF₁₆ = 2*16²+A*16¹+F*16⁰ = 512 + 160 + 15 = 687₁₀

Now, transform from decimal to binary the number 687. Divide the number repeatedly by 2, keeping track of each remainder, until we get a quotient that is equal to 0:

Now, construct the integer part base 2 representation, by taking the remainders starting from the bottom of the list:

687₁₀ =  1010101111₂

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

int main()

{

// variable

   int n;

   int mi=INT_MAX;

   int mx=INT_MIN;

   double avg;

   int count=0;

   double sum=0;

   cout<<"enter a positive integer(Negative number to stop):";

   // read the input first time

   cin>>n;

   // read the input until user enter a negative number

   while(n>=0)

   {

   // calculate minimum

       if(n<mi)

       mi=n;

       // calculate maximum

       if(n>mx)

       mx=n;

       // count of entered numbers

       count++;

       // total sum of all number

       sum=sum+n;

       cout<<"enter a positive integer(Negative number to stop):";

       // read the input again

       cin>>n;

   }

   // calculate the average

   avg=sum/count;

   // print the average

   cout<<"average of "<<count<<" number is:"<<avg<<endl;

   // print the maximum

   cout<<"maximum of all number is:"<<mx<<endl;

   // print the minimum

   cout<<"minimum of all number is:"<<mi<<endl;

return 0;

}

Explanation:

Declare and initialize "mi" with maximum integer value.Similarly "mx" with minimum integer value.Read user input until user enter a negative number.Add all the number to variable "sum" and keep count of positive number entered with "count".When user enter a negative number then it will stop taking input and calculate average of all number by dividing sum with count. Also it will check for each and find the maximum and minimum among the all input.

Output:

enter a positive integer(Negative number to stop):23

enter a positive integer(Negative number to stop):10

enter a positive integer(Negative number to stop):34

enter a positive integer(Negative number to stop):22

enter a positive integer(Negative number to stop):5

enter a positive integer(Negative number to stop):-2

average of 5 number is:18.8

maximum of all number is:34

minimum of all number is:5

 The three basic responsibilities of the TCP are:

Answer:

// here is code in c++.

// include headers

#include <bits/stdc++.h>

using namespace std;

// function that calculate days, hours, minutes and seconds

void howLong(int sec)

{

   // find days

   int days=sec/86400;

   // update the seconds

   sec=sec%86400;

   // find hours

   int h=sec/3600;

   // update the seconds

   sec=sec%3600;

   // find minutes

   int min=sec/60;

   // update the seconds

   sec=sec%60;

   // output

   cout<<sec<<"seconds is "<<days<<" days,"<<h<<" hours,"<<min<<" minutes,and "<<sec<<"seconds."<<endl;

}

// driver function

int main()

{   // variable

   int sec;

   cout<<"Enter seconds:";

   // read the seconds

   cin>>sec;

   // call the function

   howLong(sec);

return 0;

}

Explanation:

Read the seconds from user.Then call the function howLong() with parameter seconds. In the function, it will first find the number of days by dividing the seconds with 86400 then update the remaining seconds.Next it will find the hours by dividing the remaining seconds with 3600 and update the remaining seconds.After that it will find the minutes by dividing the remaining seconds with 60 and update the remaining second.Then it will print the days, hours, minutes and seconds.

Output:

Enter seconds:70000

40seconds is 0 days,19 hours,26 minutes,and 40seconds.

Here's a Python implementation of the howLong function that takes the number of seconds as an integer parameter and outputs the time in days, hours, minutes, and seconds:

def howLong(seconds):

   days = seconds // 86400

   hours = (seconds % 86400) // 3600

   minutes = (seconds % 3600) // 60

   seconds = seconds % 60

   return "Time is {} days, {} hours, {} minutes, and {} seconds.".format(days, hours, minutes, seconds)

Thus, we format the output string using the obtained values for days, hours, minutes, and seconds and return it.

Answer:

I attached you the answer in the picture

Explanation:

First, let's see the relationship between the logic gates and truth tables:

The operation of logic gates in relation to one another may be represented and analyzed using a branch of mathematics called Boolean Algebra which, like the common algebra, deals with manipulation of expressions to solve or simplify equations. Expressions used in Boolean Algebra are called, well, Boolean expressions.

AND Gate:

The AND gate is a logic gate that gives an output of '1' only when all of its inputs are '1'.  Thus, its output is '0' whenever at least one of its inputs is '0'. Mathematically, A∧B = A · B.

OR Gate:

The OR gate is a logic gate that gives an output of '0' only when all of its inputs are '0'. Thus, its output is '1' whenever at least one of its inputs is '1'. Mathematically, A∨B = A + B.

Having this in mind, we just need to use basic Mathematical Logic operations
