routing......................

Static routing is a data communication concept describing one way of configuring path selection of routers in computer networks. It is the type of routing characterized by the absence of communication between routers regarding the current topology of the network.[1] This is achieved by manually adding routes to the routing table. The opposite of static routing is dynamic routing, sometimes also referred to as adaptive routing.

The Freshest laptop designs

The Freshest laptop designs
ASUS G51JX
With aesthetics becoming almost as important a factor in usability and performance when it comes to buying a laptop these days, manufacturers are using teams of consultants to get the design just right for a particular market before they even start putting the parts together. Business users will be looking for something that projects a corporate image of sleek efficiency, often in matt black, whereas teenagers will be more interested in bright colours and funky originality, and there is a whole raft of different requirements in between. Laptop news covers the latest designs in innovative laptops to hit the market in recent months.

Notebooks are becoming increasingly lighter and thinner, and taking on the role of fashion accessories to project a personal image as well as sophisticated machines for processing data and keeping in touch with friends and colleagues.

Intel's Core-i technology is at the heart of the laptop revolution, with these ultra-fast and ultra-small microprocessors allowing for ever-smaller designs and increased performance. They are fitted into a whole range of electronic devices apart from laptops, from digital signs to automated machines. Fitting them into laptops allows the kit to work anywhere up to three times faster than those using the Core 2 technology of older ranges.........

An empty street, an empty house
A hole inside my heart
I'm all alone, the rooms are getting smaller.
I wonder how, I wonder why, I wonder where they are
The days we had, the songs we sang together.(oh yeah)

And all my love, I'm holding on forever
Reaching for the love that seems so far

[Chorus:]
So I say a little prayer
And hope my dreams will take me there
Where the skies are blue, to see you once again... my love.
All the seas from coast to coast
To find the place I Love The Most
Where the fields are green, to see you once again... my love.

I try to read, I go to work
I'm laughing with my friends
But I can't stop to keep myself from thinking. (oh no)
I wonder how, I wonder why, I wonder where they are
The days we had, the songs we sang together.(oh yeah)

And all my love, I'm holding on forever
Reaching for the love that seems so far

So I say a little prayer
And hope my dreams will take me there
Where the skies are blue, to see you once again... my love.
All the seas from coast to coast
To find the place I Love The Most
Where the fields are green, to see you once again...

To hold you in my arms
To promise you my love
To tell you from the heart
You're all I'm thinking of

Reaching for the love that seems so far

So I say a little prayer
And hope my dreams will take its there
Where the skies are blue, to see you once again... my love.
All the seas from coast to coast
To find the place I Love The Most
Where the fields are green, to see you once again... my love.

Say it in a prayer (my sweet love)
Dreams will take it there
Where the skies are blue (woah yeah), to see you once again my love. (oh my love)
All the seas from coast to coast
To find the place I Love The Most
Where the fields are green, to see you once again.... My Love.

description about social networking sites...........................................

   
These days the social networking sites have become extremely popular among the youth as well as the professional people. Keeping in mind, the growing popularity of these sites and the effect it has and the benefits that it brings along, it can be easily predicted that its popularity is sure to grow much more. Some of the sites such as Friendster and MySpace are the two most popular sites that aim to build special niche for people who share common interests and passions. Whereas social networking sites such as Twitter and LinkedIn are more professionally related and help the business men promote their businesses.

However, everything has a positive and negative side. Similarly, the social networking sites are also made up of their set of pros and cons.

Analyzing The Pros of social networking: The social networking websites are more like the virtual meeting places where people can just chill and hang out with friends. They can discuss on different topics, share information, and exchange files and pictures. There are some people who use these sites as a platform to meet long lost friend and batch mates, whereas there are others for whom it becomes a bridge to meet their future love. You can either reconnect with your friends and family members or search a dating partner. Some people also use these websites to promote their blogs and services. The professional people uses this as a medium to raise their visibility, get noticed, tell about their company, service, and get more clients.

By joining different communities, now people can easily know about the latest news related to that community. You can easily get the experts advice on any challenge you may face related to their topic of interest. And the best part of this is that the advice is free. You don't need to pay a single paisa for it. Experts are always ready to give their advice and share information with you. These are just some of the several positive things that have contributed to make social networking really popular among people and spread smiles. It has made world a small pace and everyone can stay connected.

Analyzing The Cons of social networking:

Social networking of course helps in a lot of ways but the users have to really careful to stay secure and safe. Security is one of the topmost concerns of social networking sites that you currently use. This is mainly because the social networking sites allow you to display your personal information such as name, location, and email address. There are some people who always in search of a fake identity. If they get all the information about you on internet, they may use your identity for different type of illegal activities, which may cause you problems in future. It is always advisable to don't provide your entire identity information online.

You may get many requests for adding as friends or joining different communities. Always try to know as much as possible before adding anyone as friend or joining any community. Because they may use fake identity or may involve in some illegal activities, which may spoil your image. ..........................................
