For any node of the circuit in I = out I . Note that the choice of “in” or “out” for any circuit segment is arbitrary‚ but it must remain consistent. So for the example of Fig. 2 we have I1 = I2 + I3 . 2. For any closed circuit‚ the sum of the circuit EMFs (e.g. batteries‚ generators) is equal to the sum of the circuit voltage drops:

MOLETRONICS-“an invisible technology” ABSTRACT As a scientific pursuit‚ the search for a viable successor to silicon computer technology has garnered considerable curiosity in the last decade. The latest idea‚ and one of the most intriguing‚ is known as molecular computers‚ or moletronics‚ in which single molecules serve as switches‚ "quantum wires" a few atoms thick serve as wiring‚ and the hardware is synthesized chemically from the bottom up. The central thesis of moletronics

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased

RFSim99 is a free linear S-parameter based circuit simulator offering schematic capture‚ simulation‚ 1 port and 2 port S-parameter display and file support‚ tolerance analysis‚ stability circles‚ and much more.It can cost large sums of money to get a workstation seat at some of the high end simulation and analysis software suites. But the underlying mathematics that these programs use is not secret‚ it is in the public domain and there are low cost or shareware packages that will do the same computations

semiconductors devices demands a greater purity than an afforded by some metallurgical grades of silicon. Silicon wafers used as substrates in the manufacture of discrete electronic devices that include transistors‚ and also in the development of integrated circuits that are found in computer chips. The reason for silicon is that silicon has a wonderful property of forming a high quality oxide when exposed to oxygen at high temperatures. This oxide forms insulating films and allows many devices to be built

Circuit switched networks rely on dedicated point-to-point connections during transmission. There are many differences between the two whereas they usually end up on separate sides of a corporation. Circuit switched networks were traditionally used for phone calls and packet switched networks handled all the data. With the long distant reach of phone calls

Classical computing has been operating using a binary system measured in bits. These bits can have only two states‚ zero and one. These states are used to represent‚ store and process data. The binary architecture has been used in computers since Konrad Zues built the first programmable computer in 1941(CITATION). As computers have become more advanced so has the complexity and magnitude of the problems that they can solve. With the current rate of advancement defined by Moore’s law transistors
