C programming language

What is C language ?

It is a high level language developed by Dennis Ritchie at Bell Labs in the mid 1970s. Although originally designed as a systems programming language C has proved to be a powerful and flexible language that can be used for a variety of application from business programs to  to engineering. C is a particularly popular language of personal computers because it is relatively small - it requires less memory than other languages.
The first major program written in C was the UNIX operating system, and for many years C was considered to be inextricably linked with UNIX. Now a days C is  independent of UNIX and very important.
Although it is a high-level language, C is much closer to assembly language than are most other high-level languages. This closeness to the underlying machine language allows C programmers to write very efficient code.

what is Android ? 

Android is an operating system based on the Linux kernel, and designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008.
The user interface of Android is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Internal hardware such as accelerometersgyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented. Android allows users to customize their home screens with shortcuts to applications and widgets, which allow users to display live content, such as emails and weather information, directly on the home screen. Applications can further send notifications to the user to inform them of relevant information, such as new emails and text messages.

What is an IP address :-

In simple terms, its a number that consists of four numbers, separated by periods, that can be between 0 and 255. This number identifies the device (comptuer) that is connected to the Internet, which is a TCP/IP network. It is like the address of your house, but instead of a house number, street, city, state, zipcode, it looks something like this: 127.0.0.1
Each device on the Internet gets assigned a unique IP Address. No two devices can have the same IP Address just like no two houses on your street have the exact same address.

For what is an IP address:-

When your computer is on the Internet, anything you do requires data to be transmitted and received. For example, when you visit a web site, such as tekchandrahi.blogspot.com, data is transmitted to your computer in order to load the content of the web page. The server where tekchandrahi.blogspot.com is located needs to know where to send the data. When you connect to tekchandrahi.blogspot.com, it receives your IP Address and then knows where to send the data. For example, someone that needs to mail you a letter has to know your address in order to send it to you just like a server needs to know your IP Address to send you data.

About Internet

This page is all about how  we all going to advance technology day by day due to best invention by our inventor, we are very thank full to that for our elders.

 The world as we know it is run over a network that connects all of us. We know this network as the internet. The internet is one connection after another, making long distance communication and the sharing of videos/pictures possible, and its all done by signals being carried across the globe.

     Long distance communication was not easy during the time of writing letters. It could take weeks or even months for a letter to get to its final destination. That was all changed with the invention of the telephone. The telephone allowed sound to be carried over vast amounts of distance, but nothing compares to the internet. The internet allowed us to show our faces from the US to China in a matter of milliseconds. The communication from the internet has changed social lives, people and the greatest of all it has allowed businesses to be ran from anywhere on the globe.

     Pictures and Videos can now be easily carried across the globe. These ,what would be known as media devices, can be sent or received anywhere around the world, making sharing ourselves that much easier. Media lets us connect with each other, and lets us capture the world around us. With media we can make the world stand still. Sharing media has become extremely popular with sites being released such as, YouTube, Myspace, Facebook, and every other website created for the sole purpose of sharing your life with others.

     Signals are carried through wires and are now even put out without wires to carry them. These signals carry everything from phone calls to pictures to files, over the internet and allow them to connect anywhere at anytime to anyone.
