This situation occurs when the minimum hardware requirements
of OS is not sufficient then blue screen appears.

ram problem or may be device driver problem.

While installing windows xp, blue screen occurs:-
RAM is not working property
Data Cable has some problem
H/W requirement not match

Hi this shyam mohan.M


Go to command promote and type (ipconfig /all) in that 
physical adress.  physical adress nothing but a mac adress.

This is Venu.b


We can't change the MAC address of system. It's uniq. It's 
created by manifacturer by the time of Manifacturing.

Physically we can change the MAC address but logically we 
can change the MAC address

In linux, you can change the hardware (MAC) address of your 
machine.This is how it is done.I'am aware about windows.


# ifconfig eth0 down
# ifconfig eth0 hw ether 00:80:48:BA:d1:20
# ifconfig eth0 up
# ifconfig eth0 |grep HWaddr
it done!!!

U can incress packet size from 32 byes to more through 
fallowing commans

ping <source ip address> -l 5000 -t

e.i

ping 192.168.1.100 -l 5000 -t

through this commnand we check lan cable. we send packet. 
we can incress packet size 5000 to upto 65000

POD Ping of Death, ping is and ICMP protocol normally it’s 
use send and receive 64bytes , increasing this ICMP bytes 
from 64 to 65,535 it call Ping Death , Generally It is ICMP 
Ping Attack in security World

Bcoz data link layer bind mac address with frame for 
recognize to which device that frame handed over

MAC (Media Access Control), It is Unique Physical Address 
of any Network device, it’s L2 Base address, because of 
it’s Unique & all network device are programmed on based of 
their L2 Mac base algorithms,
It’s faster than the L3, L2 Have Unique Hardware Identity 
that is call MAC, because always hardware base is faster 
than Software Base L3, so L2 Can Make Fast Communication 
then L3

Technical term for data transmission in the direction from 
the subscriber to the network, or rather back to the 
provider or Internet provider. Also called back channel . 
The opposite transmission direction, the 'transmission 
channel', is called the 'uplink' in technical jargon.
                          OR
A connector on a LAN hub to link a hub or a subnetwork to a 
port on a second hub. Some hubs have a separate port for 
uplinking

uplink is a port of hub through which we can connect 
another hub.........

Uplink is the signal path from an earth station to a satellite

Uplink is term use for connecting two LAN switches or Hub.

working between patch panel and switch, through organiser 
the cables will pass 
it has 2 types 1U, 2U

organiser is nothing but it organized everything what we 
given as a input & we expecting the output. It will work 
through the hard disk.

A panel of network ports contained together, usually 
within a telecommunications closet, that connects incoming 
and outgoing lines of a LAN or other communication, 
electronic or electrical system. In a LAN, the patch panel 
connects the network's computers to each other and to the 
outside lines that enable the LAN to connect to the 
Internet or another WAN. Connections are made with patch 
cords. The patch panel allows circuits to be arranged and 
rearranged by plugging and unplugging the patch cords.

a connection point for drop and patch cable.a patch panel 
has one or more rows of RJ45 or other connectors.drop 
cables are connected to the connectors.cables run between 
the connectors to connect drop cable is needed.

Patch panel is a device where are nework ports connected 
each other, there are two types of panels 1.UTP patch panel 
2.Fiber patch panel. UTP patch panel is used to connect cat 
cable and Fiber patch panel is used to connect fiber patch 
chords which is used in FDDI technolgies.

Patch panel is like Switch Board and all systems LAN
interface connected to this panel. This panel work as
mediator between switch and system or LAN and WAN
connectivity....

Uplink port provides the Connectivity between Two Or more 
Network Devices in the Network.
