"what are the problems with tcp over wireless network?"

1 answer:

8 0

The TCP protocol treats bit errors as congestion problems, which leads to a sub-optimal error correction. Wireless networks have a much higher bit error rate than wired ones, and the TCP protocol is not optimized for that.

Create a java class for Bank Accounts with these public String attributes: ownerName, acctNbr and these private double attribute

Readme [11.4K]

Answer:

public class BankAccounts

{

public String ownerName;

public String acctNbr;

private double debits;

private double credits;

public BankAccounts(String ownerNm, String acNum)

{

debits = 0;

credits = 0;

ownerName = ownerNm;

acctNbr = acNum;

}

public void addDebit(double debitAmt)

{

if(credits > (debits + debitAmt))

debits = debits + debitAmt;

else

System.out.println("Insufficient balance");

}

public void addCredit(double creditAmt)

{

credits = credits + creditAmt;

}

public double getBalance()

{

double balance = 0;

if((credits - debits) > 0) // return the value if there is actually some balance left.

balance = credits - debits;

return balance; //returns 0 if credits are lesser or equal to debits

}

Explanation:

Here class name is BankAccounts which can be used to create a new bank account whenever any user wants to open a bank account. This class will help to track any new account opening, debits and credits operations carried out on that account.

We have a constructor here, which accepts 2 arguments i.e. Bank account Owner Name and Account Number. The constructor also sets the values of debits and credits as 0.

The methods addDebit(), addCredit() and getBalance() help to perform Debit and Credit operations on the account.

NOTE: The method getBalance() returns a positive value only when credits are greater than debits.

The method addDebits() can add debits only as the condition that the credits are greater than the resultant debits.

The code for class BankAccounts is hereby attached.

maxonik [38]

Answer: integer overflow

Explanation:

The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.

In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.
