How Does Internet Work?
Let us try to know, some of the technicalities relating to the working of Internet. It may be stated that the procedure of Internet's working is associated with a new type of switching methodology known as 'packet switching'. Packet switching techniques take a structured approach in that they divide an individual message or information into separate 'packages', each of which is transmitted independently through the network. In other words, the Internet works by breaking down all the information which needs to be transmitted into 'packets', which contain not only the data to be transmitted, but also information indicating where it has to reach, where it came from and to what other 'packets' of data it is related to. Because these packets are in a standard form, and a standard method of addressing is used for them, they can be passed from any 'Internet-aware' point on the network to the next until they reach their intended destination. The advantage of this technique is that since the network has to deal with smaller standard size packets in a pre-determined way, a faster transmission rate can be achieved. Also the network is able to make its own decisions on routing, and can change these dynamically as traffic conditions change, with no apparent disadvantage to the end user. By breaking transmission into standard data packets, transmission across the Internet is made efficient and robust.
