6. Two OSI layers which known as "flow
Control" which are those? Write them and
explain.
Flow control is generally implemented on two
layers Datalink Layer (Layer 2) and Transport
Layer (Layer 4).
[Note: (i). Data link layer may provide flow control
"on the wire". (ii). Network layer provides flow
control between routers by ICMP. The end
terminals usually do not use the network layer
barely. IP does not provide flow control. (iii).
Transport layer, more specifically TCP provides
flow control by a backtracking algorithm while
UDP does not. TCP has various flow and
congestion avoiding protocols, such as TCP Vegas.
So, when routers have flow control problems, it is
handled in the network layer, when end points have
this problem, it's handled in the transport layer.]

7. What is firewall? Explain its work. Draw a
LAN network and a firewall where firewall
will be situated.
Firewall-A firewall is software used to maintain
the security of a private network. Firewalls block
unauthorized access to or from private networks
and are often employed to prevent unauthorized
Web users or illicit software from gaining access to
private networks Connected to the Internet. A
firewall may be implemented using hardware,
software, or a combination of both.
Firewalls generally use two or more of the
following methods:
a) Packet Filtering: Firewalls filter packets that
attempt to enter or leave a network and either
accept or reject them depending on the
predefined set of filter rules.
b) Application Gateway: The application
gateway technique employs security methods
applied to certain applications such as Telnet
and File Transfer Protocol servers.
c) Circuit-Level Gateway: A circuit-level
gateway applies these methods when a
connection such as Transmission Control
Protocol is established and packets start to
move.
d) Proxy Servers: Proxy servers can mask real
network addresses and intercept every
message that enters or leaves a network.
e) Stateful Inspection or Dynamic Packet
Filtering: This method compares not just the
header information, but also a packet’s most
important inbound and outbound data parts.
These are then compared to a trusted
information database for characteristic
matches. This determines whether the
information is authorized to cross the firewall
into the network.

10. Suppose, you are implementing “Overdraft
Account (OD)” class using java for a
banking app. An OD type account is opened
with an approved loan limit (ex 100000/-).
The account holder can deposit any amount
of money in the OD account at any time.
S/he can draw an amount of money from the
account (acn) until sufficient acn balance.
S/he allowed to draw money beyond his/her
acn balance if the total over-drawing
amount remains within the loan limit. A
java sketch for OD acn is given bellow &
code is expected to run in multi-threading
mode. (same code with run by different
counter in the blank)
Code:
public class ODAccount extends
BankAccount {
double limit;
public void ODAccount (double
setLimit) {
$this->balance= 0; //super
class has balance property
$this->limit= setLimit;
}
public void depositMoney (double
deposit Amount) {
balance= balance+
depositAmount;
public void drawMoney
(double drawAmount) throws
ODLimit Exceeded {
if (balance –
drawAmount>=-1*limit)
balance= balance-
drawAmount;
else throw new
OD Limit Exceeded ();
}
