Token Ring - Technology in Computer Networking

The technology, 'Ethernet' at the early age was quite simple. As it was developed much before the advent of 'Microprocessor', the whole technology was much more less demanding to intelligence of the network structure and the workstations. Though this forms a low cost network, but there reliability in data communication was very poor. But 'Token Ring' came into play at the time when we are already enjoying the microprocessor technology.

Intelligent Machines - Artificial Intelligence

Intelligent Machines - Artificial Intelligence

Humans are the most intelligent among all the living beings in the world. At least we, the humans think so. From the initiation of our civilization, we have been developing numerous instruments. These instruments were used in daily life and as well as for the servival. We never stoped and kept dveloping the old ones and inventing new ones. With the development of instruments we build devices. And complicated devices formed machines. We had been trying to develop such system that not only be used to accomplishe tasks but also help us to do much more complicated job for human. Thus machines evolved. Still we are not satisfied. We are now trying mak to make the machines as intelligent as ours. We cannot feed organic brains to the machines. But still we are on the way of make them intelligent with logical reasoning, mathematical calculation, sensing environment with various input devices and various complicaed algorithms. The intelligence, thus building up in the machines is known as Artificial Intelligence.

Atlast new buses are available - Kolkata

Atlast new buses are available - Kolkata

All the commercial vehicles, registered before January 31, 1993, were banned according to the order from Calcutta High Court in July 2008 and is applicable for Kolkata and its outskirts.The order was supposed to be implemented by December 31, 2008. But the date of imposing the ban was postponed to July 31, 2009. The State Government decided to implement the Court order from July 25, 2009. No doubt the descision was nothing but a fair one to protect our Kolkata from curbin pollution. But as the earning of a huge number of people and specially the bus woners is affected considerablly, there were always some issue with the descision and the implementation. There were also stricks of Bus and Autorickshaw. Even autorickshaw stricks in few places were indefinite. News media reported violences in some areas also. But still, for our beloved Kolkata, we welcome the ban.

Black Hole - Mystery

Black Hole - Mystery

Black Hole is I think the most popular mystry in Space Science. The word "black hole" certainly thrills most of us. What is black hole ? Black Hole is a huge mass certered in a very small volume and definitely with very very high density. Generally dead star is the source of the mass forming black hole. Some scientists say that if a star undegoes "Supernova" state and explodes, the scattered mass collapses all together and starts forming black hole. With the time these mass become so dense that it occupies almost zero volume and infinite density. This state is known as absolute "singularity". Thus the gravitational filed of this cluster becomes so strong that nothing can come out of it. Even the light cannot escape. As we cannot locate this with emmited or reflected light, it seems dark and we mention this as black hole.

Many years ago in 1800 centuries, there was birth of this divine system. Though there were huge differences in look & feel and as well as in functionality with the modern ones, but still that was the beginning of computer era.

When we are talking about modern computers, we must mention a name - Charles Babbage. He is considered as the "Father of Modern Computer" for his invention of "Difference Engine" and "Analytical Engine". By birth, he was British. He was born in London on 26th December 1791.
