A mobile is like women :-
Talks non-stop,
Costs a fortune,
Disturbs when your busy
And when U need them urgently, they have no service.

Q: Why was the leper caught speeding? A: He couldn't take his foot of the accelerator.

Wat frustrates a Buddhu? Wen his wife delivers twins & he cant find the father of the second child.

One day i read smoking is bad, i stopped smoking. one day i read drinking is bad, i stopped drinking. one day i read SEX is bad, i stopped reading

Gud Morning... Kindly observe SILENCE for two minutes in the memory of those poor mosquitoes who died last night after sucking ur blood. Thanks.

A boy goes to see a cabare dance. His mom gets angry & asks him: Did u see anything there that u were not supposed to see? Boy: Yes, I saw dad.!

Monsoon's heavy rain or Summer's top heat,
your friendship is the reason why I breathe.
Tell me Darling, What is Sweet?
Is that You or Your Heart Beat..
If love is water, I'll give u the ocean. If kisses are spaces, I'll give u the universe... If heat was your love and care, how I wish the sun was beside me...

If I could be any part of you,
I'd be your tear.
To be conceived in your heart,
born in your eyes, live on your cheeks,
and die on your lips.

What's the difference between your and my smile?
U smile when you are happy and I smile when you are happy.

Flowers will die, sun will set.. But u r my love that i wont forget..
Ur name is so precious,it will nvr grow old.. Its engraved in my HEART wit letters of Gold!

Dreaming of YOU makes my night worthwhile.
Thinking of YOU makes me Smile.
Having YOU is the best thing ever
and Loving YOU is what I plan to do FOREEVER

A Really Bad Day

There was this guy at a bar, just looking at his drink. He stays like that for half of an hour.

Then, this big trouble-making truck driver steps next to him, takes the drink from the guy, and just drinks it all down. The poor man starts crying. The truck driver says, "Come on man, I was just joking. Here, I'll buy you another drink. I just can't stand to see a man cry."

"No, it's not that. This day is the worst of my life. First, I fall asleep, and I go late to my office. My boss, outrageous, fires me. When I leave the building, to my car, I found out it was stolen. The police said that they can do nothing. I get a cab to return home, and when I leave it, I remember I left my wallet and credit cards there. The cab driver just drives away."

"I go home, and when I get there, I find my wife in bed with the gardener. I leave home, and come to this bar. And just when I was thinking about putting an end to my life, you show up and drink my poison."

There are times when I fall in love with someone new,
but I always seem to find myself back in love with you.

You brought a new meaning to my simple life,n u made it beautiful with your undesirable love....u make me smile even when ur not around..u make me feel loved when i most miss u.whatever it is u can make me whole again.

I m feeling so happy, do u know why? cuz i m so lucky, do u know how? cuz God loves me.Do u know how? cuz he gave me a gift. Do u know what? its YOU my love.

The secret of love is seeking variety in your life together, and never letting routine chords dull the melody of your romance.

I get the best feeling in the world when you say hi or even smile at me because I know, even if its just for a second, that I've crossed your mind.

Your smile can be compared to a flower
Your voice can be compared to a cuckoo
Your innocence to a child
But in stupidity you have no comparison
You're the best!

You are like the sunshine so warm, you are like sugar, so sweet. you are like you. and that's the reason why I love you!

Can i say i love you today? if not, can i ask you again tomorrow? and the day after that? Because i'll be loving you every single day of my life

Little keys can open big locks, simple words can express great thoughts. A text from u never fails to make me smile the whole day through.

Some people were born with talents. They can do beautiful things with their skills, knowledge and technology. But no one is as talented as you. You just come near, and there is already beauty.

Love seems the swiftest, but it is the slowest of all growths. No man or woman really knows what perfect love is until they have been married a quarter of a century.

Husband: Darling, years ago u had a figure like Coke bottle. Wife: Yes darling I still do, only differnece is earlier it was 300ml now it's 1.5 litter.

A woman is sitting at a bar. A man approaches her. Hi, honey, he says. Want a little company? Why? asks the woman. Do you have one to sell?

An apple a day keeps the doctor away, but if doctor is cute, forget the fruit..

God thought that since he couldn't b everywhere he made a mother. Then devil thought that he couldn't b everywhere he made a mother-in-law.

A Friend is Sweet when its NEW Its Sweeter when its TRUE But you know that its the sweetest when it is U

Remove your Shirt, Remove your Pants too, ahhhh uhhhhh remove ur kurti now ahhh.... Thanks God, Finally the suitcase is closed.

Eyes: To look at you, Hands: To pray for you, Mind: To care for u, Heart: To love you and Legs: To kick u if u forget me.

Why'd the couple stop after 3 children?
Cos they heard every fourth child born is chinese.

I feel something in my heart, it's like a little flame, every time I see you, this flame lights up, this flame is special for you, because I LOVE YOU!.....

Every night when I look at the moon, it reminds me of you, how you can see the same moon. It makes me sometimes sad because I can see the moon, but I can´t see you.

What's Ur, important for me? Ur thinks is my breath, Ur feels become my beating, Ur breath pour in me spirit, Ur whispering awaken my whole body, Ur sight feels objective of my life, U r as much important as I, I can't imagine I can't explain, I only Love u forever.

If i could give your one thing in life, I would give you the ability to see yourself through my eyes, only then would you realise how special you are to me!

Feelings are many but words are few,clouds are dark but sky is blue;Love is a paper, life is glue,every thing is false,only My Love is TRUE

When situation gets you down, remember there's someone in Heaven who loves you and watches over you and there's someone on Earth who cares. I do LOVE YOU.

Every life in this world has been painted by God's own hands, That's why I am thankful God, bcoz when he painted my life he included a lovely color that is YOU!

What’s New @ Cisco Live…our 20th Year!

2009-06-21T11:08:00.000-07:00

We have a lot going on at Cisco Live 2009 and I wanted to take moment to address a few of the things that are new at this year’s event.

For the first time, Cisco Live 2009 will be a hybrid event, offering both in-person and online experiences. The introduction of our 3D interactive platform, Cisco Live Virtual, gives us the opportunity to offer attendance options to customers who may not be able to attend in person. As with any immersive, interactive conference like Cisco Live, the onsite experience and the virtual experience are not the same and are not designed to be. Rather, we are able to offer a viable attendance alternative to a variety of audiences for those unable to take advantage of a traditional, in-person event experience.

It is not our intention to replace either the in-person or virtual experience, rather to create an integrated portfolio of event experiences that will collectively comprise Cisco Live.more

Securing the Network: It Takes a Village

2009-06-21T11:07:00.000-07:00

In the past couple of weeks, I’ve been blogging about Smart Grid from a positive, green technology standpoint. But those of us in security know that it’s also rife with potential security risks. And recent events underscore that point. In April, The Wall Street Journal reported that spies from other countries had hacked into the grid, planting software that could have been used to disrupt service. While no such disruption occurred, the incident does point to the need for enhanced monitoring and control over such vital services.

The Obama administration is not taking the possibility of cyber threats lightly. In fact, it has undertaken several initiatives to make cybersecurity a top priority. To begin with, they’ve committed to developing a comprehensive policy for the United States. This positions the White House to assume a leadership role in protecting the nation’s information infrastructure, and fosters global cooperation on cybercrime to ensure a safer networking environment.

IP Addressing

2009-06-09T00:51:00.001-07:00

An IP address is a unique logical identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number, and represented as 4 decimal values of 8 bits each. The decimal values range from 0 to 255. This is known as "dotted decimal" notation.

Example: 192.189.210.078

It is sometimes useful to view the values in their binary form.

192 .189 .210 .078
11000000.10111101.11010010.1001110

Every IP address consists of network identifier and node identifier. The IP network is divided based on Class of network. The class of network is determined by the leading bits of the IP address as shown below.

Address Classes

There are 5 different address classes. You can determine which class any IP
address is in by examining the first 4 bits of the IP address.

Class A addresses begin with 0xxx, or 1 to 126 decimal.
Class B addresses begin with 10xx, or 128 to 191 decimal.
Class C addresses begin with 110x, or 192 to 223 decimal.
Class D addresses begin with 1110, or 224 to 239 decimal.
Class E addresses begin with 1111, or 240 to 254 decimal.

Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine. Class D addresses are reserved for multicasting. Class E addresses are reserved for future use. They should not be used for host addresses.

Now we can see how the Class determines, by default, which part of the IP address belongs to the network (N) and which part belongs to the Host/node (H).

Class A: NNNNNNNN.HHHHHHHH.HHHHHHHH.HHHHHHHH
Class B: NNNNNNNN.NNNNNNNN.HHHHHHHH.HHHHHHHH
Class C: NNNNNNNN.NNNNNNNN.NNNNNNNN.HHHHHHHH

In the example, 192.189.210.078 is a Class C address so by default the Network part of the address (also known as the Network Address) is defined by the first three octets (192.189.210.XXX) and the node part is defined by the last one octets (XXX.XXX.XXX.078).

In order to specify the network address for a given IP address, the node section is set to all "0"s. In our example, 192.189.210.0 specifies the network address for 192.189.210.078. When the node section is set to all "1"s, it specifies a broadcast that is sent to all hosts on the network. 192.189.210.255 specifies the broadcast address.

Private Subnets

There are three IP network addresses reserved for private networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as an intranet. Internet routers never forward the private addresses over the public Internet.

CCNA Practice Exams

2009-06-09T00:47:00.000-07:00

We unconditionally guarantee that if you use SemSim CCNA Exams, you will pass your CCNA certification test.
Use our CCNA practice exams and then take the real exam. If you fail, we refund your money—and you can even keep the software.

The Cisco CCNA exams are challenging (some would say grueling) 90-minute live-on-the-computer tests, with questions that constantly shift both their form and their content, and question technologies (such as drag-and-drop, configuration and troubleshooting virtual routers through interactive simulations, and command based fill-in-the-blanks) that can't be replicated with pen-and-paper. In other words, you can't cram for this exam the way you might have crammed for a test in school. The only way you'll pass the test is to know the material and be familiar with the structure of the test. You need a dynamic practice test engine like SemSim, that supports the full range of question types found on the CCNA exam, including extensive support for simulations, drag-and-drop and exhibit-based questions.

You already know that as a Cisco Certified Network Associate, you'll be in demand in the workplace. Your CCNA is your ticket to higher-paying, more satisfying work assignments—it's worth an average bonus of $4,715 per year (Source: TCPMag.com 2004 Salary Survey). Yet while Cisco does not reveal the actual fail rate on the exam, most estimates claim that between 50% and 80% fail the exam on first attempt- many of them because they are not prepared for the full range of question formats and stumble over unfamiliar ones.

Since it costs $125 each time you take the CCNA test, you want to achieve your Cisco Certified Network Associate certification on the first try. With only $39 investment in SemSim CCNA Exams, available by instant download directly to your PC, you can be certain—or get your money back.
