Second Life is so popular because it allows its </font><font color="#ff0000">Residents to do so much, like assemble buildings, design fashion lines, create businesses and clubs and much more. It is an online simulation of the real world.</font><br><font color="#ff0000">You can create your own 3-D person, also known as an avatar. Second Life is a place to connect with old friends or make new friends. You can communicate in real time over IM. </font><br><font color="#ff0000">Second Life also allows you to use voice chat. </font><br><font color="#ff0000">Second Life is a social networking site for people 18 and older.

The government&#39;s Intelligence Advanced Research Projects Activity has suggested that online anonymity in 3-D worlds such as second life leads to terrorism is an example of the role anonymity plays in Second Life. Another example of anonymity in Second Life is about the man who cheated on his wife on Second Life. After his wife divorced him he married the woman he cheated with over Second Life. This is an issue of anonymity because neither person knows if each other is really who they say they are.</font><br><font color="#edcf47" size="5"><u><b>Sources</b></u></font><br><a class="external" href="http://armsitgs.wetpaint.comhttp://computer.howstuffworks.com/internet/social-networking/networks/second-life.htm" rel="nofollow" target="_blank">http://computer.howstuffworks.com/internet/social-networking/networks/second-life.htm</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://burninglife.secondlife.com/whatisSL" rel="nofollow" target="_blank">http://burninglife.secondlife.com/whatisSL</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.thaindian.com/newsportal/india-news/wife-dumps-hubby-after-he-went-for-virtual-second-wife_100118928.html" rel="nofollow" target="_blank">http://www.thaindian.com/newsportal/india-news/wife-dumps-hubby-after-he-went-for-virtual-second-wife_100118928.html</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.thaindian.com/newsportal/health/virtual-wife-never-met-her-virtual-hubby-in-real-life_100119470.html" rel="nofollow" target="_blank">http://www.thaindian.com/newsportal/health/virtual-wife-never-met-her-virtual-hubby-in-real-life_100119470.html</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://work.secondlife.com/en-US/successstories/" rel="nofollow" target="_blank">http://work.secondlife.com/en-US/successstories/</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://virtualworlds.flexiblelearning.net.au/content/section+2.3.1%28goodbadugly%29.htm" rel="nofollow" target="_blank">http://virtualworlds.flexiblelearning.net.au/content/section%202.3.1(goodbadugly).htm</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.theaustralian.com.au/news/features/virtual-terrorists/story-e6frg6z6-1111114072291" rel="nofollow" target="_blank">http://www.theaustralian.com.au/news/features/virtual-terrorists/story-e6frg6z6-1111114072291</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://tltc.shu.edu/virtualworlds/mediawiki/index.php/Creating_your_Second_Life#Creating_your_Second_Life_Account" rel="nofollow" target="_blank">http://tltc.shu.edu/virtualworlds/mediawiki/index.php/Creating_your_Second_Life#Creating_your_Second_Life_Account</a><hr size="1"><br/>http://armsitgs.wetpaint.com/page/Data+Miningcarmshttp://armsitgs.wetpaint.com/page/Data+MiningThu, 19 Nov 2009 11:15:21 CST<font size="5"><b>What is it? </b><font size="4"><br>Data Mining is the &quot;extraction of hidden predictive information from large databases&quot; , which allows business to accumulate patterns and data that &quot;normal databases&quot; would overlook.

A huge benefit from the monitor is its consistency with real-time reports of patients which allows nurses and doctors to keep hourly updates instead of continuously keeping watch on the every patient. </font><br><b><u>How does it work?</u> <br> </b><font size="2">Electronically monitoring patients allows nurses and doctors to monitor a patients vital signs during their stay at a hospital. It reads a persons current body temperature, blood pressure and oxygen, using infrared and radio-based locators, a ring sensor and wearable stethoscopes, to monitor the changes in long term patients that may be in a life or death situation. </font><font size="3"><br> <br></font><u><b>Advantage&amp;Disadvantage</b></u></font><br> Patient monitoring is vital to care in operating and emergency rooms, intensive care and critical care units. However, for emergency room patients, patient monitoring is unnecessary because they are not long term patients. Their monitoring would be pointless due to the fact that they would leave by the end of the day. <br> Patient monitoring can reduce the risk of infection and other complications, as well as assist in providing for patient comfort. There are not enough doctors and nurses to be around for each patient inside a hospital. That is why electronically monitoring patients is efficient, if a long term patient suddenly has a heart attack the patient monitor will alert for medical assistance. If patients weren&#39;t provided with a monitoring system and nurses only checked on each patient a certain time period, then they have a higher risk of an unknown time of death. <br><font size="5"><font size="3"> </font></font><b>Manages the major side effects of surgery <br> Manages the patient&#39;s coexisting diseases<br><font size="5"><font size="3"> M</font></font>aintains and supports homeostatic control of oxygenation<br> Alerts of sudden change in patients</b><br><br>Short-term patients are not placed under monitoring systems because they are not in need of a long term health report but rather an updated of how their body systems are doing. For that reason check ups and minor infections do not require the usage of electronically monitoring patients. The electronic patient monitor does not monitor all existing diseases therefore, it is not dependable for all hospitals and hospital practices. The range of health issues that the electronic monitor detects is not very broad, which makes it a disadvantage for the patients in respiratory therapy and recovery rooms. Meaning that they do not have the ability to be electronically monitored. Additionally, the patient monitor can also be shut down during power outages, or the sensors may fail to sense bloodpressure and body temperature. <font color="#ff0000"><br></font><b><br><u><font size="5">Social and Ethical Impact<br></font></u></b><font size="3"><font size="2">Electronically monitoring patients has an impact on its reliability because there are still studies on the machine to improve glitches and to expand it&#39;s monitoring abilities. There are many times that the blood pressure reports or body temperature readings are incorrect leading to an undependable resource. What if a patient was asleep and the electronic monitor failed to read the heartbeats, doctors would rush in trying to bring the patient to life when he was in reality, sleeping. This is dangerous because the patient is at risk as the doctors assume that the patient is on the verge of dying, they will go through any process to bring the vital signs on the monitor to reappear. However, the vital signs may not appear because the machine failed to read the patients signs. Also when there are power outages if the monitors do not have a second reliable energy source, it will shut down which means a failure to keep real-time updates on the patients vital signs. For example if a hospital were to experience a black out and suddenly one of their electronically monitored patents receives a heart-attack, nurses and doctors will not be alerted of the sudden attack. Proving that the monitor has become unreliable. With that, many factors such as reliability, are being considered as improvements on the electronic monitor is being created. <br><br>Article of a girl that experienced the process of patient monitoring:<br></font></font><b><a class="external" href="http://armsitgs.wetpaint.comhttp://www.newyorker.com/reporting/2007/12/10/071210fa_fact_gawande" rel="nofollow" target="_blank">http://www.newyorker.com/reporting/2007/12/10/071210fa_fact_gawande</a></b><br><font size="3"><font size="2"><br></font></font> <b><a class="external" href="http://armsitgs.wetpaint.comhttp://www.lsdregistry.net/gaucherregistry/hcp/partic/greg_hc_p_monitor.asp" rel="nofollow" target="_blank">http://www.lsdregistry.net/gaucherregistry/hcp/partic/greg_hc_p_monitor.asp</a><br></b> <b><a class="external" href="http://armsitgs.wetpaint.comhttp://www.ercim.org/publication/Ercim_News/enw60/amato.html" rel="nofollow" target="_blank">http://www.ercim.org/publication/Ercim_News/enw60/amato.html</a></b> <br> <b>http://www.anesthesia-analgesia.org/cgi/content/full/101/1/161</b> <br> <b><a class="external" href="http://armsitgs.wetpaint.comhttp://www.smiths-medical.com/products/patient-monitoring/" rel="nofollow" target="_blank">http://www.smiths-medical.com/products/patient-monitoring/</a></b> <br><hr size="1"><br/>http://armsitgs.wetpaint.com/page/Green+Computing+and+Hardware++Disposalcarmshttp://armsitgs.wetpaint.com/page/Green+Computing+and+Hardware++DisposalTue, 17 Nov 2009 09:01:54 CST<b><font size="5"> </font></b><br><b><font size="5">What is <font color="#00ff00">Green Computing</font>?</font></b><br><br>Green computing, refers to environmentally sustainable computing or IT.

Cyberwarfare is a term used to describe the use of computers and the Internet in conducting a conflict in the virtual world. The results of cyberwarfare often reflect upon physical world. For example, an attack upon a company&#39;s network or server can cause data loss therefore can ruin the company.<br></font> <br> <font size="5">How it works</font> <br> <font size="3">Cyberwarfare is composed of an attack or a compromise of a computer-based system. Rather than using bullets and bombs, the warriors in these confrontations use bits and bytes. Using the current technology, hackers find weaknesses in their targets and exploit them. There are three major sectors targeted by most nations involved in cyberwarfare: </font><ul><li class="MsoNormal"><font size="3"><b>Financial attacks</b> could interrupt the world&rsquo;s major markets by taking down electronically-controlled commodity exchange networks, or by shutting down web-based operations of major banks or retailers. </font></li><li class="MsoNormal"><font size="3"><b>Infrastructure attacks</b> can damage a nation by shutting down critical utility systems, such as electrical grids, or by wrecking havoc on others, such as opening dams, or interfering with the air traffic control </font><font size="3">system. </font></li><li class="MsoNormal"><font size="3"><b>Governmental attacks</b> can shut down the ability of government officials to communicate with one </font><font size="3">another, steal secret digital communications, or release things like tax information, social security information, or other personal data to the public.</font></li></ul><br><br> <font size="5">Advantages</font> <ul><li><font size="3">Useful strategy against terrorists by allowing the U.S. to trace the attack&rsquo;s origin.</font></li><li><font size="3">Less deadly than conventional warfare.</font></li><li><font size="3">Life saving military uses:</font></li><ul><li><font size="3">Giving the enemy forces incorrect information about an assault.</font></li><li><font size="3">Avoid information interference.</font></li><li><font size="3">Ally troop movements&rsquo; coverage.</font></li><li><font size="3">Interception of information about enemy forces.</font></li></ul></ul><br><font size="5">Disadvantages</font> <br><ul><li><font size="3">Fast-evolving technology mean unprepared defense by many nations.</font></li><li><font size="3">Hackers can infiltrate ally military or air traffic control system and can cause physical harm or casualty.</font></li><li><font size="3">An enemy can attack from anywhere, even from within the targeted state.</font></li><li><font size="3">Hard-to-cure Cyber-epidemic caused by <a href="http://armsitgs.wetpaint.com/page/Viruses" target="_self">viruses</a> (ex: Code Red, Slammer and Nimda) that can cause billions of dollars worth of damage to companies, businesses, and government</font></li></ul><br> <br> <font size="5">Social and Ethical impacts</font><br><br><font size="4"><u>Security</u></font><br><font size="3">With highly advanced technology, hackers can shut down the victim&rsquo;s firewall making his computer system more susceptible to attacks.

Because most information are outputted as audio or visual format, most output devices are commonly known as monitors or speakers. However, there are many other types of output devices.<br><br></font></font><h2><u><b>Types of Output Devices</b></u></h2><ul><li>Monitors</li><li>Speakers</li><li>Printers</li></ul><h2><u><b>Monitors</b></u></h2><br><font size="4"><font size="3"><font size="4"><font size="3">A monitor&#39;s display is the most-used output device on a computer. The display provides instant feedback by showing you text or graphic images whenever you work or play. The monitor screen is composed up of numerous individual dots of color known as pixels. Resolution is known as the density of the pixels. A resolution on a display can be expressed by identifying the number of pixels on the horizontal axis and the number of pixels on the vertical axis. Resolution is affected by numerous factors, including the size of the screen<br><br>Two factors affect the size of your display :<br></font></font></font></font><ul><li>aspect ratio - Like televisions, computer have an aspect ratio of 4:3. This means that the ratio of the width of the display to the height is 4 to 3<br></li><li>screen size - Screen sizes are normally measured in inches from one corner to the corner diagonally across from it.</li></ul><h3><font size="4">LCD and CRT Monitors</font></h3><br><font size="4"><font size="3"><font size="4"><font size="3">LCD (Liquid Crystal Display) monitors and CRT (Cathode Ray Tube) monitors are two types of monitors which both have their advantages and disadvantages.<br><br>CRT monitors are very large and heavy. Because of their bulky size, they have become very inconvenient for space-wise. Although they are very large and bulky, the screen size is not accurate to their display. CRT monitors also consume a heavy large amount of energy and is highly affected by the magnetic interference. The flickering effect, or the low refresh rate, is also a major downside on purchasing CRT monitors. However, CRT monitors take a clear advantage when it comes to color purity.<br><br></font></font></font></font><font size="4"><font size="3"><font size="4"><font size="3">LCD monitors are very thin and light compared to their CRT counter-parts. The pixels are very pleasing and does not take very much space. These LCD monitors are even more accurate to their screen size and do not consume as much energy than the CRT monitors making them extremely economical. However, LCD monitors produces &quot;dead pixels.&quot; Dead pixels are simply pixels on the LCD monitors that do not function and are not repairable. This means that they stay on your display permanently.<br><br>Most computers and laptops are capable of dual monitors which can increase productivity by 40%.</font></font></font></font><br><font size="4"><font size="3"><font size="4"><font size="3"><br></font></font></font></font><h2><u><b><font size="4"><font size="3"><font size="4"><font size="5">Speakers</font></font></font></font></b></u></h2><br>Speakers are one of the most common output devices. The computer outputs information through electrical signals through speakers. Speakers take the electrical signal and translate it back into physical vibrations to create sound waves. The speaker is composed of 3 parts: the diaphragm, the voice coil, and the magnets.<br><br><h3>Diaphragm</h3><br>Sound waves are produced by rapidly vibrating a flexible cone, or diaphragm. The cone is usually made out of paper, plastic, or metal and is attached on the wide end to the suspension. The suspension, a rim of flexible material that allows the cone to vibrate, is attached to the driver&#39;s metal frame, called the basket. The narrow end of the cone is connected to the voice coil which is attached to the basket by the spider, or a ring of flexible material. Although the spider holds the coil in position, it also allows it to move freely back and forth. Some drivers are now in shape of a dome instead of a cone. This allows the diaphragm to extend out instead of tapering in.<br><br><h3>Voice Coil</h3><br>The basis of the voice coil is an electromagnet. An electromagnet is a coil of wire, usually wrapped around a piece of magnetic metal, such as iron. Electrical current is ran through the wire and creates a magnetic field. The field has a polar orientation and is attracted to iron objects. In an electromagnet, it is possible to alter the orientation of the poles thus reversing the flow of the current. This process is the same as a stereo signal, it constantly reverses the flow of electricity. There are two output wires for each speaker, a black and a red one. These electrical signals are constantly being switched by an amplifier, fluctuating between a positive charge and a negative charge on the red wire. This alternating current causes the polar orientation of the electromagnet to reverse itself numerous times in a second.<br><br><h3>Magnets</h3><br>A permanent magnet creates a constant magnetic field. Two magnets, the electromagnet and the permanent magnet, interact with each other. When the electromagnet&#39;s polar orientation switches, so does the direction of the repulsion and attraction. The alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet thus pushes the coil back and forth rapidly, such as a piston. Whenever the coil is moved, it pushes and pulls on the speaker cone. This process vibrates the air in front of the speaker, creating sound waves. The frequency and amplitude of this wave dictates the rate and distance that the voice coil moves.<br><h2><br></h2><h2><u><b><font size="5">Printers</font></b></u></h2><br>Printers outputs information that is tangible for the user. Printer produces large amounts of information in a variety of ways. Printers are often used in business, schools, and for the personal computers at home. There are 4 different types of printers: laser printers, ink jet printers, plotters, and dot-matrix printers. <br><br><h3>Laser Printers</h3><br>A laser printer is a highly focused beam of light that write letters and draws pictures on paper. Laser printer are very large and bulky, but processes output information very efficiently. The basics of a laser printer are static electricity, the drum, and the fuser.<br><br>Static electricity is simply an electrical charge built up on an insulated object. Because opposite charged atoms are attracted to each other, objects with opposite static electricity fields cling together. Laser printers use this process as a sort of &quot;temporary glue.&quot; The core component of the static electricity system is the photoreceptor, typically a revolving drum or cylinder. This drum assembly is made out of highly photoconductive material that is discharged by light photons.<br><br>The drum is given a total positive charge by the charge of corona wire, a wire with an electrical current running through it. While the drum revolves, the printer shines a small laser beam across the surface of the paper to discharge certain points. This is how the printer &quot;draws&quot; the letters and images to be printed as a pattern of electrical charges, or electrostatic image. Once the pattern is completed, the printer coats the drum with a positively charged toner, a fine, black powder. Because the toner is positively charged, the toner clings to the negative discharged areas of the drum. When the powder pattern is completed and affixed, the drum rolls over a sheet of paper, which is moving along a belt below. With a negative charge by the transfer corona wire, the paper pulls the toner powder away.<br><br>Finally, the printer passes the paper through the fuser, a pair of heated rollers. The loose toner powder melts and fuses with the fibers in the paper. The fuser rolls the paper to the output tray giving you the results of the output information.<br><font size="4"><font size="3"><br></font></font><h3>Inkjet Printers</h3><font size="4"><font size="3"><br>Inkjet printers are the most common printers to have in any business or personal homes. An inkjet printer is any printer that places extremely tiny droplets of ink onto paper with a nozzle to create and image. These dots have different colors combined together to create photo-quality images.<br><br>The core of an inkjet printer is the print head. The print head contains a series of nozzles that are used to spray drops of ink. These ink are supplied by ink cartridges. Ink cartridges come in various combination, such as separate black and color cartridges. A stepper motor moves the print head assembly back and forth across the paper in order to create images requested by the user and uses a stabilizer bar to ensure that movement is precise and controlled. This stepper motor is attached to the print head assembly by a belt.<br><br></font></font><h3>Plotters</h3><br>Plotters are usually used by engineers or architects to draw up technical plans or blueprints. Plotters require the input of appropriate coordinates for where the desired image is to appear on the paper. Modern plotters use a sliding roller, which moves the paper against a stationary pen and plots the coordinates. The plotter pen is usually a hollow fiber rod with a sharpened end. The ink supply runs through the center of the rod and discharges through the sharpened tip. The paper moves horizontally and vertically against the pen until the drawing is complete.<br><br><h3>Dot-matrix Printers</h3><br>Dot-matrix printers use several tiny pins, aligned in a column, and strikes an ink ribbon positioned between the pins and the paper, creating dots on the paper. Characters are composed of the patterns of these dots by moving the printhead laterally across the page in very small increments.<br><br><h2><u><b>Advantages/Disadvantages</b></u></h2><br>The advantages of output devices allow us to connect to other individuals in a global society. Individuals who author their own content can now be viewed or heard by these output devices. This is followed by collaboration and the spreading of knowledge digitally.<br><br>Although hearing and seeing content is such an amazing process, the quality of the audio or display is a major factor. The higher the quality, the higher the expenses to pay for these output devices. Some machines may be disfunctional after a certain period of time or is constantly needing to be repaired.<br><br><h2><u><b>Social and Ethical Issues</b></u></h2><br>One key major social and ethical issue is reliability. These are all hardware devices and sometimes there may be glitches or bugs that can cause spontaenous harm to the hardware device. Users depend on these hardware devices to work efficiently to the topmost of its quality and does not expect the hardware to fail.<br><font size="4"><font size="3"><br><font size="4">Sources<br><font size="3"><a class="external" href="http://armsitgs.wetpaint.comhttp://www.wacona.com/output/output.html" rel="nofollow" target="_blank">http://www.wacona.com/output/output.html</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.techterms.com/definition/outputdevice" rel="nofollow" target="_blank">http://www.techterms.com/definition/outputdevice</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.howstuffworks.com/monitor.htm" rel="nofollow" target="_blank">http://www.howstuffworks.com/monitor.htm</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.pcreview.co.uk/articles/Consumer-Advice/LCD_vs_CRT/" rel="nofollow" target="_blank" title="http://www.pcreview.co.uk/articles/Consumer-Advice/LCD_vs_CRT/">http://www.pcreview.co.uk/articles/Consumer-Advice/LCD_vs_CRT/</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://electronics.howstuffworks.com/speaker.htm" rel="nofollow" target="_blank" title="http://electronics.howstuffworks.com/speaker.htm">http://electronics.howstuffworks.com/speaker.htm</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://computer.howstuffworks.com/laser-printer.htm" rel="nofollow" target="_blank" title="http://computer.howstuffworks.com/laser-printer.htm">http://computer.howstuffworks.com/laser-printer.htm\</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://computer.howstuffworks.com/inkjet-printer.htm" rel="nofollow" target="_blank" title="http://computer.howstuffworks.com/inkjet-printer.htm">http://computer.howstuffworks.com/inkjet-printer.htm</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://www.ehow.com/how-does_4968203_a-plotter-work.html" rel="nofollow" target="_blank" title="http://www.ehow.com/how-does_4968203_a-plotter-work.html">http://www.ehow.com/how-does_4968203_a-plotter-work.html</a><br><a class="external" href="http://armsitgs.wetpaint.comhttp://bits.me.berkeley.edu/mmcs/PROPRNT2/DOTMATRX.HTM" rel="nofollow" target="_blank" title="http://bits.me.berkeley.edu/mmcs/PROPRNT2/DOTMATRX.HTM">http://bits.me.berkeley.edu/mmcs/PROPRNT2/DOTMATRX.HTM</a><br></font></font></font></font></div></td><td width="14"><br></td><td width="260"><div class="WPC-edit-area"><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> <br><br><br><br><br><br><br> <br><br><br><br><br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> <br><br><br><br><br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br> <br><br><br><br><br> </div></td></tr></tbody></table><hr size="1"><br/>http://armsitgs.wetpaint.com/page/The+Motherboardstephanieuwagbaihttp://armsitgs.wetpaint.com/page/The+MotherboardMon, 16 Nov 2009 21:14:05 CST<blockquote> <blockquote> <font color="#0630c9" face="Impact" size="5"><u>What is the Motherboard?<a class="external" href="http://armsitgs.wetpaint.comhttp://upload.wikimedia.org/wikipedia/commons/b/b4/Asus_a8n_VMCSM02.jpg" rel="nofollow" target="_blank"> </a></u></font> <br><font color="#000000"><font face="Helvetica" size="4">The motherboard is the circuit board that holds many of the components of the system and contains the computer&#39;s central processing unit (CPU).
