by default Static route Ad value is 1 but.....
you can change it....

by default static route has AD[administrative distance] 
value 1

yes, you can run ur pc without hard disk. you need a dos  
in floppy or cd

You can run a PC w/o a HDD using a BOOTP server, which 
sends the OS to the target m/c and in addition to that it 
acts as a DHCP server to provide IP address

PC without HD is a dumb terminal and boots to an image on 
the network. It could be a citrix or windows terminal 
server or better yet t could be vertual PC with a shared 
storage on a SAN type of shared storage. Current NICs have 
a cability to ask for DHCP and connect to a resource 
through the usage of bootp.

computer run without hard disk throgh cd/ pen drive & other 
bootalbe media.

yes we can run a pc without hdd by using thinclients

i never seen any computer which is runing without or with 
harddisk.

Yes, You can run computer using bootable CD, which contains
OS  in a cd this OSs are Knoppix and Chevna. it loads OS in
RAM, you can save and surf internet too until is restarted

with flash memory computer can run without hard disk.its 
proven.

this all answers are not cleared. plz answer clear.

yes we can run computer without HDD. The solution is 
ThinClient.

To Rana,Which type of system u have seen

Its depend your network structure.........

No! we can not change the MAC (media access control) 
address of network card.The MAC address is 48 bits address 
in haxadecimal form and
its identy devide in two part. first 24 bit difine by OUI 
(orgnization unique identy) and second 24 bit difine by VAI 
(vedors assine identy) The OUI is IEEE.so thats why we can 
no change the indenty of network card 
{26-11-2d-7}{a-21-ac}
   OUI        VAI

we can not change the MAC (media access control) 
address of network card.The MAC address is 48 bits address 
in haxadecimal form and

no we cannot change the 48bit mac address in any network 
pheripheralls.

Yes, we can.

no we can't change mac address of network card

Yes we can change the MAC address of a particular NIC or
Router . Some of the routers providing inbuilt tool to do
the mac cloning.

And lots of 3rd party tools are available to change the MAC
address of NIC . 

Regards,
Pradeep

yes we can change the MAC  add form 3 party tool but when we
restart a pc it  will gone

yes we can change mac address with third part tools the 
name of tools is A-mac .

YES WE CAN CHANGE MAC ADDRESS WITHOUT THIRD PART TOOLS.

IPLC - International Private Leased Circuit
ISDN - Integrated Switched Digital Network

and main difference between IPLC & ISDN is 
IPLC is lease(dedicated) line for a particular user
ISDN comes in  circuit switching.

You have to have active dorectory 2003 and it only runs on 
64 bit windows environment.

active directory is must be installed.

Firstly windows environment is 64 bit.

Microsoft

Cell switching is done by ATM.
AtM uses fixed 53 bytes to transfer the packet.

In computer networking, DMZ is a firewall configuration for 
securing local area networks (LANs). 
In a DMZ configuration, most computers on the LAN run 
behind a firewall connected to a public network like the 
Internet. One or more computers also run outside the 
firewall, in the DMZ. Those computers on the outside 
intercept traffic and broker requests for the rest of the 
LAN, adding an extra layer of protection for computers 
behind the firewall. 

Traditional DMZs allow computers behind the firewall to 
initiate requests outbound to the DMZ. Computers in the DMZ 
in turn respond, forward or re-issue requests out to the 
Internet or other public network, as proxy servers do. 
(Many DMZ implementations, in fact, simply utilize a proxy 
server or servers as the computers within the DMZ.) The LAN 
firewall, though, prevents computers in the DMZ from 
initiating inbound requests. 

DMZ is a commonly-touted feature of home broadband routers. 
However, in most instances these features are not true 
DMZs. Broadband routers often implement a DMZ simply 
through additional firewall rules, meaning that incoming 
requests reach the firewall directly. In a true DMZ, 
incoming requests must first pass through a DMZ computer 
before reaching the firewall.

A DeMilitarised Zone (DMZ) is a seperate network located in 
the neutral zone between a private (inside) network and a 
public (outside) network

ARP-Adress Resolution Protocol[protocol no 14]
It is use to convert logical address i.e IP add to physical 
add i.e MAC add because sender and Rxr communication based 
on MAC add not IP add.

There are a few password recovery/crack tools but none of 
them work in a windows domain only in a workgroup 
environment and weak passwords can be cracked.

type it in notepad.

there are so many tool are available to crack the domain
user password  but those are only work in within vlan it's
true i tested

Barracuda Spyware Firewall - Quick Start Guide
The Barracuda Spyware Firewall is a network gateway 
appliance that is installed between
your internal network and the Internet, to perform content 
filtering, stop spyware and virus
downloads, block inbound and outbound access to known 
spyware Web sites, filter
offensive content, and detect spyware accessing the 
Internet. The Barracuda Spyware
Firewall can also notify you of the presence of spyware on 
computers in your network. It
will provide comprehensive protection of your web surfing.
Getting Started
This guide provides you with setup instructions for the 
Barracuda Spyware
Firewall. We recommend reading these instructions fully 
before starting the
setup. To begin setting up your Barracuda Spyware Firewall, 
you will need the
following:
• Barracuda Spyware Firewall
• AC Power Cord
• Ethernet Cables
• Mounting Rails (model 610/810 only)
• VGA Monitor (recommended)
• PS2 Keyboard (recommended)
Physical Installation
To install the Barracuda Spyware Firewall:
1. Fasten the Barracuda Spyware Firewall to a 19-inch rack 
or place it in a
stable location.
2. Connect an Ethernet Cable from your network switch to 
the LAN ethernet
port on the front panel of the Barracuda Spyware Firewall. 
The WAN port
will be used after the basic configuration is complete.
3. Connect a Standard VGA Monitor, PS2 Keyboard, and AC 
power cord to the
unit. Note: Immediately after connecting an AC Power Cord 
to the unit, it
may power ON for a few seconds and then power OFF. This is 
because
the unit is designed to automatically return to a powered 
ON state in the
event of a power outage.
4. Press the POWER button on the front panel to turn the 
unit on.
Configure IP Address and Network Settings
If you have a monitor connected, the Barracuda Spyware 
Firewall will display the
Boot Menu initially, and the Administrative Console login 
prompt once fully
booted. To begin the configuration:
1. Login to the Administrative Console using the admin 
login:
• Login: admin
• Password: admin
2. Configure the IP Address, Subnet Mask, Default Gateway, 
Primary DNS
Server and Secondary DNS Server as appropriate for your 
network.
3. Save your changes.
If you do not have a monitor and keyboard and want to set 
the IP using the
RESET button on the front panel, press and hold the RESET 
button per the
following table:
IP address Press and hold RESET for…
192.168.200.200 5 seconds
192.168.1.200 8 seconds
10.1.1.200 12 seconds
Barracuda Spyware Firewall Configuration
Use a computer with a Web browser that is connected to the 
same network as
the Barracuda and follow these steps:
1. In your Web browser’s address bar, enter http:// 
followed by the Barracuda’s
IP address, followed by the default Web Interface HTTP Port 
(:8000). For
example, if you configured the Barracuda with an IP address 
of
192.168.200.200, you would type: http://192.168.200.200:8000
2. Login to the Barracuda Spyware Firewall Web interface as 
the administrator:
Use Username: admin Password: admin
3. Go to the Basic�� IP Configuration page and configure the 
following:
• Pass Through Management: set this value to Soft Bypass**. 
You will
switch this to Active in a later step.
4. Click any one of the Save Changes buttons to save all of 
the information.
**WARNING: On model 410 and higher, when Hard Bypass is 
enabled, you
will only be able to manage the device from the management 
ethernet port
on the back of the Barracuda Spyware Firewall.firmware is a 
computer program that is embedded in a hardware device, for 
example a microcontroller. It can also be provided on flash 
ROMs or as a binary image file that can be uploaded onto 
existing hardware by a user.

As its name suggests, firmware is somewhere between 
hardware and software. Like software, it is a computer 
program which is executed by a microprocessor or a 
microcontroller. But it is also tightly linked to a piece 
of hardware, and has little meaning outside of it

Its Very simple 

Lets start with firmware :-

Firmware is a software deployed / installed in routers,
hardware devices, cmos ..etc in order to upgrade the version
or features of a particular product. 

Based on the improvisation of the application it is a easy
way to upgrade the software .

Spyware :- Is a software which corrupts data sending
unnecessary packets from PC to out side network and vice
versa. Its some sort of virus programs which will occupy the
disk space as well as system resources.

I think now its clear .
