Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

Semiconductors are either solid or liquid material‚ able to conduct electricity at room temperature more readily than an insulator‚ but less easily than a metal. Electrical conductivity‚ which is the ability to conduct electrical current under the application of a voltage‚ has one of the widest ranges of values of any physical property of matter. Such metals as copper‚ silver‚ and aluminum are excellent conductors‚ but such insulators as diamond and glass are very poor conductors. At low temperatures

How Shakespeare Uses Literary Devices to Achieve the Moral in Macbeth In William Shakespeare’s play‚ “Macbeth”‚ one dominant moral is made clear to the audience‚ do not tempt fate‚ let nature take its course. Some of the ways that Shakespeare achieves this is through the development of conflicts in the plot and also through dialogue‚ vivid imagery and metaphors created by the atmosphere in the play. The characters develop in the early acts to identify the protagonist and antagonists to the audience

I. Introduction a. Back ground of the Study Triac The TRIAC is a three terminal semiconductor device for controlling current. It gains its name from the term TRIode for AlternatingCurrent. It is effectively a development of the SCR or thyristor‚ but unlike the thyristor which is only able to conduct in one direction‚ the TRIAC is a bidirectional device. TRIAC The TRIAC is an ideal device to use for AC switching applications because it can control the current flow over both halves of

My nursing goals for the next three years. Nursing is a career which I believe that needs to come from the heart and I have at all times appreciated with respect. My aim in doing my education in nursing was because I always wanted to achieve an extended and successful profession in the health and medical field. I suppose the responsibilities of a nurse can be very demanding and frantic in certain instances but nothing can be equal to the joy and satisfaction it brings. There are many specialized

a plot device in which the end is curiously abrupt so that the main characters are left in a difficult situation without offering any resolution of conflicts. Why use a Cliffhanger? • As a result of a sudden end‚ suspense is created at the very end of the novel‚ leaving the readers in such a state that they could not help but to ask‚ “What will happen next?” This type of end is common to the serially published novels which end at a dramatic or suspenseful moment. Cliffhanger plot device ensures

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 postive

from the people of the United States. John Kennedy uses the rhetoric devices repetition‚ pathos‚ and allusion in order to persuade people to support America going to the moon. To have the audience remember his speech‚ Kennedy emphasizes repetition. He kept repeating certain words like "one" and "we" for example.
