Answer:

Crosstalk, Jitter, Impulse noise.

Explanation:

Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.

Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.

Impulse noise (also referred to as spikes) is the primary source of errors in data communications.  Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.

Counter measures

Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.

Amplifiers can be used to increase signal strength since the connection would run across 4 floors.

Which of the following function declarations correctly expect an array as the first argument?
NARA [144]

Answer:

Only

Option: void f1(float array[], int size);

is valid.

Explanation:

To pass an array as argument in a function, the syntax should be as follows:

functionName (type arrayName[ ] )

We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.

"The goal of this assignment is to give you some experience building a program that uses objects. You will use the BankAccount c
MArishka [77]

Answer:

see explaination

Explanation:

Please find my detailed implementation.

I have tested with Single Bank account object.

You can create array list of Bank Account in test program:

public class BankAccount {

private String name;

private int accountNumber;

private int PIN;

private double balance;

public BankAccount(int accN, int pin) {

accountNumber = accN;

PIN = pin;

}

public BankAccount () {

name = "Undefined";

accountNumber = 0;

PIN = 0;

balance = 0;

}

public String getName() {

return name;

}

public int getAccountNumber() {

return accountNumber;

}

public int getPIN() {

return PIN;

}

public double getBalance() {

return balance;

}

public void setName(String name) {

this.name = name;

}

public void setAccountNumber(int accountNumber) {

this.accountNumber = accountNumber;

}

public void setPIN(int pIN) {

PIN = pIN;

}

public void setBalance(double balance) {

this.balance = balance;

}

public void withdrawal(double amount) {

if(amount <= balance) {

balance = balance - amount;

}

}

public void deposit(double amount) {

balance += amount;

}

public void transferFunds (double amount, BankAccount toBankAccount) {

if(amount >= balance) {

toBankAccount.setBalance(amount + toBankAccount.getBalance());

balance -= amount;

}

}

atOverride //change the at with the at symbol

public String toString() {

return "{id:"+accountNumber+", name:"+name+", pin:"+PIN+", balance:$"+balance+"}";

}

}

#########

public class BankAccountTest {

public static void main(String[] args) {

BankAccount myAccount = new BankAccount(526323450, 1234);

myAccount.setName("Pravesh");

myAccount.setBalance(345.64);

System.out.println(myAccount);

BankAccount anotherAccount = new BankAccount(); //default constructor

System.out.println(anotherAccount);

}

}

Consider the following JavaScript program:
dem82 [27]

Answer:

Variable       Where Declared

In Sub1 :

        A        Sub1

        Y        Sub1

        Z        Sub1

        X        Main

In Sub2:

        A        Sub2

        B        Sub2

        Z        Sub2

        Y        Sub1

        X        Main

In Sub3 :

        A        Sub3

        X        Sub3

        W       Sub3

        Y        Main

        Z        Main

Explanation:

In static-scoped languages with nested subprograms, the declaration of a variable is checked with the subprogram, if it is not found, it check within the parent method that called it, it continue until it find a declaration, if no declaration is found, it display an error.

In Sub1, a, y, z is declared there while the declaration of x is found in main.

In Sub2, a, b, z is declared, declaration of y is found in sub1 and declaration of x is found in main.

In Sub3, a, x, w is declared while the declaration of y, z is from the main.
