BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

Electronic surveillance has changed in many ways since the passing of the USA Patriot Act. Therefore‚ electronic surveillance can be divided into 4 categories; wiretaps‚ tracking devices‚ stored communications and subscriber information‚ and pen registers and trap devices (Hall‚ D. 2105). Before the Patriot Act‚ you would have to have to show very high need to get a warrant for wiretapping‚ kind of like getting a super warrant and this was due to The Wiretap Act and the Title III of the Omnibus

These included Distributed Denial of Services‚ identity theft‚ social engineering and man-in-the middle attack. A topic that will be covered is type of vulnerability‚ type of attack‚ the impact of those attack and protection mechanism used to prevent attacks to happen. 2.0 Distributed Denial of Services (DDOS) 2.1 Type of Vulnerability The first vulnerability that will cause hackers to infect

Topic 12 ATOMIC STRUCTURE: Electronic configuration 12. 1. Ionization energy If an electron obtains enough energy it jumps beyond the highest energy level and becomes a free electron: the atom itself becomes a positive ion. This electron transition is represented as follows: n = 1 to n = (. Notation n = ( refers to the “world” outside the atom – beyond the control of the nucleus; any electron outside an atom has no potential energy (energy = 0). With hydrogen the ionization energy can be

relative there through mobile phones. It has been observed that students bringing electronic gadgets to school are distracted from their studies. Intrapersonal reaction and communication are missing because studies are immersed in texting and gaming. There is a need to conduct a study of this condition because it has been proven by the result of Annual National Test of the DepEd that students with the most electronic gadgets in the cities and towns have lower result in these tests compared to rural

Kristi Malone The Electronic Era was responsible for the advancement of technology. In my opinion‚ the biggest forms of technology that came were cell phones and personal computers. The invention of cell phones made it possible to communicate with others while not around a landline. It was also now possible to call for help if an emergency arose. The invention of personal computers came with the invention of the internet and made it possible to research a topic of interest without spending hours
