Answer:
Data link layer of OSI model is creating the erroneous segments
Explanation:
The Open System Interconnection (OSI) model is a conceptual framework about how communication occurs between devices over the Internet. It has seven layers, (Physical, Data, Network, Transport, Session, Presentation and Application layer). The purpose of this hierarchical layer system is to understand the structure of communication between devices and do troubleshooting easily if a fault occurs. As in this question, Marry is troubleshooting her company LAN network. She finds out that data segments that the client is encoding are resulting in errors in the encoding. Now the question arises, how she found the cause of the error. The OSI model helps her in understanding the problem.
As you know, the data link layer of the OSI model is responsible for the encoding and decoding of data segments. This layer ensures the reliability of the physical layer, and responsible to provide error-free transfer of data from one node to another on a network. It is also responsible for frame synchronization and flow control. The data link layer is divided into sub-layers:
1. Media Access Control Layer: this layer controls how a computer on the network gains access to the data and transmission permission.
2. Logical Link Control Layer: This layer controls frame synchronization, error checking and flow control.
Therefore, Marry founds data link layer of the OSI model is creating the erroneous segments in encoding.
The python program that creates a Bankaccount class for a Bank ATM that is made up of the customers and has a deposit and withdrawal function is given below:
<h3>Python Code</h3>
# Python program to create Bankaccount class
# with both a deposit() and a withdraw() function
class Bank_Account:
def __init__(self):
self.balance=0
print("Hello!!! Welcome to the Deposit & Withdrawal Machine")
def deposit(self):
amount=float(input("Enter amount to be Deposited: "))
self.balance += amount
print("\n Amount Deposited:",amount)
def withdraw(self):
amount = float(input("Enter amount to be Withdrawn: "))
if self.balance>=amount:
self.balance-=amount
print("\n You Withdrew:", amount)
else:
print("\n Insufficient balance ")
def display(self):
print("\n Net Available Balance=",self.balance)
# Driver code
# creating an object of class
s = Bank_Account()
# Calling functions with that class object
deposit()
s.withdraw()
s.display()
