any other entity in another part of the world. Modern telecommunication networks attempt to make this idea of ‘universal connectivity’ a reality. Connectivity in telecommunication networks is achieved by the use of switching systems. This subject deals with the telecommunication switching systems and the networks that use them to provide worldwide connectivity. 1.1 Evolution of Telecommunications Historically‚ transmission of telegraphic signals over wires was the first technological development in

Topic 2: Understanding Network Protocols I. What is a network? A computer network‚ or simply a network‚ is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information. LAN - Connects devices within a single office or home or among buildings in an office park. The key aspect here is that LAN is owned entirely by a single organization. - In simplest conception‚ it consists of

"Code-Switching" Growing up on the out skirts of Philadelphia and a father with a sensitive job‚ requiring him to pack up and move in a moment ’s notice‚ my family moved in excess of two dozen times. This in itself took an enormous toll on the well-being of the family. Every time another move came about‚ came with it new challenges‚ social challenges that instigated change within myself. Constantly torn between friends‚ family and school life‚ I had evolved to be a routine that I came to learn in

with respect to Quality-of-Service considerations. A recurring theme in this journal has been the traditional lack of security in Internet technologies and systems. We have examined several ways in which security has been added at all levels of the protocol stack. This time we look at firewalls‚ a popular way to segregate internal corporate intranet traffic from Internet traffic while still maintaining Internet connectivity. Fred Avolio gives the history of firewalls‚ their current state‚ and future directions

Terminology[edit] An integrated circuit is defined as:[2] A circuit in which all or some of the circuit elements are inseparably associated and electrically interconnected so that it is considered to be indivisible for the purposes of construction and commerce. Circuits meeting this definition can be constructed using many different technologies – see for example thin-film transistor‚ thick film technology‚ or hybrid integrated circuit. However‚ in general usage integrated circuit has since come to refer

Kyoto Protocol In the world today there are talks about why and how the people of this planet are polluting the rivers‚ lakes‚ soil‚ and even air. With these talks countries are coming up with great ways to reduce this problem. They see the effects and they are happy and life goes on but there is another problem‚ the one the everyday people just can ’t solve with their own hands‚ that problem is the theory of global warming. During December of 1997‚ a meeting in Kyoto‚ Japan‚ started a huge
