Why Internet is important

Internet, in its most basic form can be defined as global network of numerous computers and computer networks all over the world , allowing one to access and exchange information , over this network. It is possible to put information related to one's activities on the internet. It facilities the speedy sharing of information among research and education communities.  It has caught the fancy of businessmen, through advertising, as well as performing business transactions over the net. All this is leading to a more efficient style of working and an improved quality of life in general. 

 

As you know, Internet allowing one to access information over the network, and enabling information exchange by following standard protocols for development of software in terms of HTML or VRML or PHP (C- language) languages and TCP/IP for data communication, as well as business transactions.  specific websites are located by using the URL , which is a unique address.

 

Why Internet

If two personal computer connected each other, as long as two computers share a common protocol, they can exchange information.

It is possible to put information related to one's activities on the Internet, making the dream of a world without frontiers a reality. The Internet facilitates the speedy sharing of information among research and education communities. 

Advertising on the Internet is another phenomenon that has caught on in a big way. All this is leading to a more efficient style of working and an improved quality of life in general.

 

Why INTERNET?

Internet is an important tool for all professionals. Why is it important? There are a number of arguments:

Internet mechanism, is quickly send electronic mail  including phone call. The ability to communicate with someone in any easy and effective way has tremendous advantages for both sender and receiver. It is also an excellent way to communicate with a number of people simultaneously, and to route and send information to other.

to ability to exchange visual information in readable and reusable formats - figures, charts, tables, images, databases, software code - opens up possibilities for collaboration at the global as well as local levels. With the trend for specialization, the ability not only to communicate but also to actually work with colleagues in the same field scattered all over the world makes long-distance collaboration feasible.

 

More about INTERNET

 

The first thing to remember is that being 'connected to the Internet' can means a whole range of possibilities, anything from sending a simple e-mail to a colleague across the street, to logging into another computer halfway across the world in order to search and retrieve sounds, graphics and even  video, movies.

Basically, five things you can do on the Internet.

• Communication: email is a simple service that allows you send messages worldwide, through computers, in a near-real-time manner.

• File Transfer (Document -Data): Internet allows you to move data from one computer to another. This data could be in the form of documents, images, artwork, movies, sound and software.
  

• Interactive Browsing: Allows you to browse through the various information sources available on the Internet.

• Reading and posting to topic-specific bulletin boards: There is a global bulletin board service provided on the Internet. It is composed of thousands of topical groupings that you can read.

• A combination of two or more of the above which may lead to a business transaction. 

Nowadays, Internet is changing the way we live and work. Even in India,  one can now access newspapers on-line, carryout business transactions and download vast amounts of information.

INTRANET

Intranet is an in-house computer network within a company/enterprise or a closed user group,that uses the standard Internet technologies, software and protocols. It is used for intercommunication between various persons and entities with each other. 

 

Intranets are easy to install, and great way to provide access to corporate information and collaboration. One can provide a lot of things through intranets like -

• Organization related information, like employed directory, job openings, insurance policies, vacation policies etc.

• Reference manuals, user guides and technical documents of in -house products.

• Industry news consisting of summary of key events, publications and news items about your industry, your competitors etc.

• Frequently asked questions and the in-house newsletter. 

 

Who owns the INTERNET

No one owns the Internet. It is not funded by any single person, service, corporation, university or government. Every person who makes a connection, every group whose Local Area Network (LAN) becomes connected, owns a slice of the Internet.

How does the INTERNET work

There is one user sitting in front of one computer on a network. Let us say that this person is New Delhi, India. Let us also assume that this person wants to send some information to another person in Patna, Bihar, India. Now, if these people are in the same company and the company uses some corporate-wide e-mail system, the first person just enters in the name of the second person as it is known to the corporate e-mail system - usually a user name . This servers as an address for the electronic message, and the send command has the e-mail system deliver the message to the person in question. 

Now compare this to a telephone system. Within the same local company and exchange, some telephone  systems allow you to dial a digit or two to reach someone else also connected to the same local system. If the two people are not on the same exchange, then (within India, anyway) you will need to dial three to seven/ten digits at the STD code before dialing to the phone number of the concerned party. If the two people are not on the same email system, whether or not it is corporate-wide, the message needs to have some extension that serves the same function as the STD/NSD code in the phone number. The address extension is found following the @ sign in an Internet e-mail address. For example, gpsmemorialacademy@gmail.com  is the complete Internet address for a member of the staff of GPS Memorial Academy at Patna. This type of address is a fully qualified address - implying that it has all the parts/details to enable it to be de3livered to the addresses from anywhere on the network.

Once a message has an address on it, the interconnected Internet system take over. The e-mail handling system on the sender's computer packages the message and prepares it for 'shipping'. The message is broken up into small pieces called 'packets'. The packets are all addressed to the final destination. The path fro New Delhi, India, to Patna , Bihar, India , may have many different networks in it.  In fact, the packets that contain the message may not all travel over same path. Along the possible paths are special-purpose computers called routers. These computers do nothing but look at network addresses and figure out from the address what is the current best route to the destination address. Once the packets reach their destination, they are reassemble into the original message.

Router make their decisions  based on information that is constantly reaching them from all over the Net. They hear from other routers about links that are down, about others that may be congested and slow, or about routers that are no longer accepting packets for certain destinations. Each packet's destination and proposed route is evaluated individually, in the blink of an eye, and sent off along the best route for that particular packet at that particular moment.

The same sort of decision-making is applicable to all packets that traverse the Internet. Each time a packet reaches a router, its address is examined and the packet is forwarded either to another router nearer its ultimate destination or to that destination if the router is the final router on the path.

Internet is an important tool for all professionals

So Who Cares INTERNET

However, a lot of people care about the Internet. All the people who use it, even if only to send a note to someone on some other network that gateway in to the Internet, care about it. Each computer connected is owned by someone or some enterprise. The owner of the connected equipment therefore 'owns'  a piece of the Internet. The telecom companies own the pieces that carry the packets. The service providers own the packet routing equipment. So, while no one person or entity owns the Internet , all  who use it or supply materials for it play a part  in its existence.
