SPINTRONICS: AN INTRODUCTION INTRODUCTION: From the earliest transistor to the remarkably powerful microprocessers‚ most electronic devices have employed circuits that express data as binary digits‚ or bits: ones and zeroes represented by the existence or absence of electric charge. Furthermore‚ the communication between microelectronic devices occursby the binary flow of electric charges.The technologies that emerged from this simple logic have created a multitrillion dollar per

Infrared security alarm Introduction: Not so long ago an alarm was a fairly rare sight‚ however now almost every house has an alarm of some kind. One common kind of security system is an infrared home security system. These are so popular because they are easy to install without having to drill holes and lay cable infrared radiation is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The sensors are set at the door or some supervised

The Development of Personal Computers The history of the computer goes back hundreds of years. From the abacus through the modern era the evolution of computers has involved many innovative individuals. It was out of this desire to innovate many fascinating tabulating machines developed. The modern computer‚ therefore‚ evolved from an amalgamation of the genius of many individuals over a long period of history. Many people shaped the world by making the efforts to develop technology.
