Diodes Diodes are components that allow current to flow in only one direction. They have a positive side (leg) and a negative side. When the voltage on the positive leg is higher than on the negative leg then current flows through the diode (the resistance is very low). When the voltage is lower on the positive leg than on the negative leg then the current does not flow (the resistance is very high). The negative leg of a diode is the one with the line closest to it. It is called the cathode. The

Digital electronics‚ or digital (electronic) circuits‚ represent signals by discrete bands ofanalog levels‚ rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance‚ signal attenuation or parasitic noise do not leave the discrete envelope‚ and as a result are ignored by signal state sensing circuitry. In most cases the number of these states is two‚ and they are represented by

terms of electronic media for community. The internet and modern telecommunications has changed social networks and socialization greatly. It has opened up our ability to communicate over vast distances at near light speed. We now have many more ways in which to communicate in synchronous time with people at distances. Our asynchronous communication (like message boards and social networking) can now involve many more people than with non-electronic media. Another advantage to electronic media communication

Brittany Miller Psychology 201 – 09 Instructor: Mrs. Maruyama Toddlers using electronics The thought of purchasing a 500.00 Ipad or some sort of electronic for a 2 to 5 year old I find to be quiet ridiculous. I understand the point that they want the toddlers to learn how to use technology at a young age and teach them how to handle things with care. It makes sense if they had the children using theirs but going out and actually buying a 2 year old their own is quite outrageous‚ what all

Not all the information available is correct‚ and it can also be easily manipulated. Also‚ the

Advantages and disadvantages of using CAD Advantages * Can be more accurate than hand-drawn designs - it reduces human error. * You can save and edit ideas‚ which makes it easier and cheaper to modify your design as you go along. * You can modify existing ideas‚ which saves time. Disadvantages * The software itself can be expensive so initial costs are high. There are free software packages though. * Staff need to be trained how to use the software‚ which also adds to costs
