All about Internet

Nowadays,Internet is very popular and everyone knows about it.Here we talk about about working of internet,owner of internet,etc.. 


    Who owns the internet

No one actually owns the Internet, and no single person or organization controls the Internet in its entirety. The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks to other networks.It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet.




   
  What is WWW(World Wide Web) actually  

  
 Most usually Sir Timothy Berners-Lee, age 62, is credited as the father of the WWW. Conway Berners-Lee, age 96, worked on the world's first commercial electronic computer with stored programming (the Ferranti Mk. 1). Sir Timothy John Berners-Lee also known as TimBL is the father of World Wild Web(WWW).
The application protocol that makes the web work is Hypertext Transfer Protocol or HTTP. Do not confuse this with the Hypertext Markup Language (HTML). HTML is the language used to write web pages. HTTP is the protocol that web browsers and web servers use to communicate with each other over the Internet.

 How internet runs across the world 

The internet runs with the submarine cable for communication which are laid under the oceans to every continents.SEA-ME-WE3 or South-East Asia - Middle East - Western Europe 3 is an optical submarine telecommunications cable linking those regions and is the longest in the world.

Submarine cables How are they laid?

A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. Today, there are over 420 submarine cables in service, stretching over 700,000 miles (1.1 million km) around the world.Submarine cables are laid down by using specially-modified ships that carry the submarine cable on board and slowly lay it out on the seabed as per the plans given by the cable operator. The ships can carry with them up to 2,000km-length of cable.

• Circuit switching

If you had a big map of the worldwide telephone systemyou could theoretically mark a direct line, running along lots of miles of cable, all the way from your phone to the phone in your friend's house. For as long as you're on the phone, that circuit stays permanently open between your two phones. This way of linking phones together is called circuit switching.

•   Packet switching 

 Most data moves over the Internet in a completely different way called packet switching. Suppose you send an email to someone in China. Instead of opening up a long and convoluted circuit between your home and China and sending your email down it all in one go, the email is broken up into tiny pieces called packets. Each one is tagged with its ultimate destination and allowed to travel separately. In theory, all the packets could travel by totally different routes. When they reach their ultimate destination, they are reassembled to make an email again.

What are Tier companies 

• A tier one company is the most important member of a supply chain, supplying components directly to the original equipment manufacturer (OEM) that set up the chain. Creating a tiered supply chain is part of supply chain management. Its aim is to link important business functions and processes in the supply chain into an integrated business model, according to the Council of Supply Chain Management Professionals.
• In information technology, a tier 2 vendor is a smaller and less well-known provider as compared to a tier 1 vendor. A tier 2 vendor is often also limited in its geographic coverage as well. As a consequence, a tier 2 vendor is generally regarded as a secondary source rather than the preferred source.
• Tier 3 Suppliers. In the automotive industry, the term Tier 3 refers to suppliers of raw, or close-to-raw, materials like metal or plastic. OEMs, Tier 1, and Tier 2 companies all need raw materials, so the Tier 3s supply all levels.

• Cities of tier1,tier2 and tier3  -   Currently there are 8 Tier-1 cities, which include Bangalore, Chennai, Delhi, Mumbai, Hyderabad, Kolkata and Pune. The Tier-2 cities include the likes of Agra, Lucknow, Jaipur, Chandigarh, Nagpur. The rest of the cities fall under Tier-3 category.

  Is Internet free?Why we pay for internet? 

Internet is essentially a Service and any type of Service involves cost. Your Service provider spends enormous amount of money to install and maintain the resources (Inter-sea cables, Large Data- Centres, last-mile connectivity etc.) to deliver to you the content which you today call Internet. You are basically charged for delivering this content to your Home and Mobile Devices.

Further, there are many Internet Entrepreneurs and Businesses who provide their services for free but generate revenue through advertising and other means.

Because Internet will be THE binding force in unifying our planet in the coming few decades, a lot of innovative means are being devised for increased penetration of Internet in remote and far-flung and otherwise black-spots (read unconnected). Facebook, Google etc. and several government agencies are pioneering these penetration efforts.
