What are two example of ways an electronic record may be distributed to others?

What has impacted the world more: The initial creation of telephone or a smart cellphone? Explain your reasoning!

-BARSIC- [3]

If this is on personal opinion, I would say the initial creation of the telephone. Even though a smartphone practically kickstarted a whole era to technology that is still going on till this day, it was the telephone that started this all. If it wasn’t for the idea to create a phone that is more advanced than a box attached to the wall, none of these advancements would’ve happened at all. (Although that is uncertain, things do tend to have a way of working out in the end. If someone didn’t invent it, another person would’ve thought of it sooner or later.) But that is only if we’re talking long term, which I prefer because there was no limit to when the results of impact started in the prompt stated above, yet if we were to speak short term and the faster one, the credit would go to the smart cellphone. But we aren’t, because the question never specified ;)

) Consider a router that interconnects four subnets: Subnet 1, Subnet 2, Subnet 3 and Subnet 4. Suppose all of the interfaces in

erik [133]

Answer:

Check the explanation

Explanation:

223.1.17/24 indicates that out of 32-bits of IP address 24 bits have been assigned as subnet part and 8 bits for host id.

The binary representation of 223.1.17 is 11011111 00000001 00010001 00000000

Given that, subnet 1 has 63 interfaces. To represent 63 interfaces, we need 6 bits (64 = 26)

So its addresses can be from 223.1.17.0/26 to 223.1.17.62/26

Subnet 2 has 95 interfaces. 95 interfaces can be accommodated using 7 bits up to 127 host addresses can represented using 7 bits (127 = 27)

and hence, the addresses may be from 223.1.17.63/25 to 223.1.17.157/25

Subnet 3 has 16 interfaces. 4 bits are needed for 16 interfaces (16 = 24)

So the network addresses may range from 223.1.17.158/28 to 223.1.17.173/28

Write the code to produce a for loop that counts down from 20 to 0 by 2’s and prints the number each time it goes through the lo

yulyashka [42]

Explanation:

Count-controlled for loop (Three-expression for loop)

This is by far the most common type. This statement is the one used by C. The header of this kind of for loop consists of a three-parameter loop control expression. Generally it has the form:

for (A; Z; I)

A is the initialisation part, Z determines a termination expression and I is the counting expression, where the loop variable is incremented or dcremented. An example of this kind of loop is the for-loop of the programming language C:

for (i=0; i <= n; i++)

This kind of for loop is not implemented in Python!

Numeric Ranges

This kind of for loop is a simplification of the previous kind. It's a counting or enumerating loop. Starting with a start value and counting up to an end value, like for i = 1 to 100

Python doesn't use this either.

Vectorized for loops

They behave as if all iterations are executed in parallel. This means, for example, that all expressions on the right side of assignment statements get evaluated before the assignments.

Iterator-based for loop

Finally, we come to the one used by Python. This kind of a for loop iterates over an enumeration of a set of items. It is usually characterized by the use of an implicit or explicit iterator. In each iteration step a loop variable is set to a value in a sequence or other data collection. This kind of for loop is known in most Unix and Linux shells and it is the one which is implemented in Python.

Example of a simple for loop in Python:

>>> languages = ["C", "C++", "Perl", "Python"]

>>> for x in languages:

... print(x)

...

C

C++

Perl

Python

A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out

dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int userNum;

Scanner input = new Scanner(System.in);

System.out.print("Enter integer: ");

userNum = input.nextInt();

System.out.println("You entered "+userNum);

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

int userNum2;

System.out.print("Enter another integer: ");

userNum2 = input.nextInt();

int sum= userNum + userNum2; int product = userNum2 * userNum;

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

int userNum;

Scanner input = new Scanner(System.in);

This prompts the user for input

System.out.print("Enter integer: ");

This gets user input from the user

userNum = input.nextInt();

Number (1) is implemented here

System.out.println("You entered "+userNum);

Number (2) is implemented here

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

int userNum2;

This prompts the user for another input

System.out.print("Enter another integer: ");

This gets user input from the user

userNum2 = input.nextInt();

This calculates the sum and the product

int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product);
