The Media Coverage Of Hurricane Katrina Essay Example For Students

The Media Coverage Of Hurricane Katrina Essay In the early morning hours on August 29, 2005, Hurricane Katrina struck the Gulf Coast of the United States devastating the coastal line from central Florida to Texas driving many residents from their homes and causing them to flee for their lives. This paper will address concerns of racism that was found in the media coverage of Hurricane Katrina’s aftermath and then compare and contrast ethical issues in the publishing of two extremely controversial photos. Lastly, this paper will critically analyze the role that the media has in our culture and how the role the media plays can impact social change within our society. Issues of racism that was used in the media coverage, especially in light of the widely controversial photo captions, can be clearly seen when examining the two photos wherein one photo a black man is presumed to be looting whereas in the second photo take a white couple are presumed to be finding food (Sommers, Apfelbaum, Dukes, Toosi, and Wang, 2006, p. 40). We will write a custom essay on The Media Coverage Of Hurricane Katrina specifically for you for only $16.38 $13.9/page Order now It was because of this opinionated stereotype by the media that the general public determined the general idea that the black residents of the community were stealing and rioting. Additionally, the language and tone of the reporter lead readers and viewers directly to most of the assumptions made by the rest of the world (Sommers, Apfelbaum, Dukes, Toosi, and Wang, 2006, p. 40). Additionally, Because of the general precipitance of the public and the stereotyping â€Å"many false claims went unchallenged† (Voorhees, 2007, p. 416).In the aftermath of Hurricane Katrina, many residents had been driven out of their homes scrambling for food, water, and shelter. The following day after Hurricane Katrina had completely destroyed the coastal line levels residents can be. .ly, the nature of the activity in the two photos that were presented was misconstrued by the reporter through assumption or by intentional misguidance and the ethics involving the Potters Box was never applied. As I look back on this project I found researching this subject to be both interesting and challenging in addition to learning about the underlying issues of racism in the aftermath of Hurricane Katrina. However, this assignment took me deeper as I began to look at other areas where it was possible that the media had manipulated the truth to achieve a hidden agenda. This project also reminded me of the old saying, do judge a book by its cover. I was additionally reminded that we should never take anything for granted and to always research items of interest for ourselves because if we don’t we are only viewing the subject through another person’s perspective.

The High Renaissance, Bramante essays

The High Renaissance, Bramante essays The heroic vision of the High Renaissance artists and their patrons is shared, even aroused, by their wealthy patrons who set out to better the ancients. In Rome and Milan artists and architects are commissioned to aggrandize the triumphs of popes and princes, dynasties and The Church. Bramante led in his field to the realization of a powerful new scope for knowledge, representation and building. Science virtuosity, classicism, expressiveness and Neoplatonism are all celebrated in their work. Examine in this contention in the work of Bramante and show how it advances modernism. Bramantes architectural designs from the High Renaissance were crucial in the development and expression of Modernism in building designs. Over the preceding three hundred years before the High renaissance, there was a reemergence of Humanist philosophies. Starting with the teachings of St Francis of Assisi (1182-1226) there began a renewed interest human dignity inspired by Christian virtue. Developing from this in the Early Renaissance, through economic prosperity of city-states in northern modern day Italy, especially, and the rediscovery of classical Roman ideals through writing, art and architecture Humanism became a popular scholarly secular pursuit. Christianity and Humanism were studied to complement one another resulting in a type of Neoplatonism. By the time of the High Renaissance the expression of Humanistic and Christian ideals are clearly displayed in many Artists work of the time and in fact go beyond the original intents of Humanism and Christianity to develop a ph ilosophy and style that is unique to the Renaissance. This essay will explore how Bramante expressed these new ideas and how they were crucial in the development of Modernism. Born in Urbino, Bramante (1444-1514) initially studied as a painter. On moving to Milan in 1481 and working court with Leonardo he moved from painting and began designing buildings. Whi...

Lewis and Clark from the Native Americans perspective Research Paper

Lewis and Clark from the Native Americans perspective - Research Paper Example The Native Americans were poorly interpreted and failure to see their unique, cultural and historical existence. This came about because the trail they traversed had distinct cultures, dialects and tribal associations (National Geographic, 2013). The Native Americans formed part of the success of the expedition. Drouillard and Sacagawea were hired by Lewis to provide extensive support at different points of the trip. Drouillard was a hunter and a specialist in Indian sign semantics and local dialects while Sacagawea was a transcriber. Both helped save the mission as they helped in the provision of crucial necessities such as horses from the Shoshone tribe, canoes, medicines and valuable goods. The travelers' safety was not guaranteed during their expedition and Sacagawea played the role of ensuring their full safety, as was the case when the group came into contact with the Indian tribes. The Rocky Mountains were exhausting and formidable especially during the 11 day crossing in the snow led by Old Toby. The Mandan villages provided shelter and fortitude during the winter of 1804-1805 when they allowed the travelling team to build a fort amidst them. the villagers were friendly and provided food for the team. It is during this period that Lewis and Clark's life was saved from the Nez tribe that wanted to kill them. The two were saved through the intervention of an old woman who lived in the Mandan village. The chiefs from different tribes who provided friendly connections with other tribes further enhanced the success of their expedition. Without this, the voyage would have probably ended before it would have started (National Geographic, 2013) As is evident, Lewis & Clark met different tribes during their journey, and who provided help at each and every stage of the journey. Their first encounter was with the Oto Indian tribe, whose six chiefs who they honored with clothes and a flag. In return, the chiefs acknowledged their conquest and granted them access to pass through their lands. The Mandans and Hidatsas tribes from the North Dakota Territory insisted on the significance of using horses. These, according to this tribe, would be helpful in the transportation of cargo and speed up the journey as compared to travelling on foot. The neighboring tribes were generous enough to trade food stuffs and arrange for guides who gave information on the way ahead. The good relations with the tribes of the Colombia and Snake rivers proved to be useful as they provided food and quick passages through their lands. Along the journey, Lewis & Clark also met the North West, Plain and Plateau Indians with whom they shared an analogous cultural lifestyle and heritage. The Sioux, Crow and Mandans tribes were nomadic while few resided in villages. Those who lived in the country of the Colombian river were hunters, fishermen of salmon and subsistence agriculturalists. Despite the various friendly tribes, the travelers also met up with hostile tribes on thei r way to the Pacific Ocean. Such a tribe was the Blackfeet Indians, who were notorious for being hostile to intruders. The members of this tribe were equipped with rifles and sought to get more from the expeditionists. In the heat of the moment, Lewis and Reuben slew a Blackfeet warrior sparking a war between the tribe and envoys of the federal government. They also had an unfortunate encounter with the Yankton Sioux and Omaha tribes (National Geograp

Macroeconomic problem Essay Example | Topics and Well Written Essays - 1500 words

Macroeconomic problem - Essay Example The amount of money supplied by the government fixed by Fed hence making it perfectly inelastic. b) In our situation, the equilibrium interest rate will be 5.8% as this is the point of intersection of the supply curve and the money demand curve. C) When the economy is at full employment, an increase in money supply will not result in an increase in the output. In this case, the increased money supplied will result in increased level of inflation. The excess money pumped in the economy will chase the same quantity of goods and services thereby making their prices to inflate. Normally, the increases in the money supply is intended to stimulate economic growth by reducing the level of interest rates (Floyd 58). In the case of full employment, all the resources are already utilized and the increased money supplied will not achieve the intended purpose of increasing production level. Besides, the increased inflation will make the local currency unstable and discourage foreign investors fr om holding the local currency. This can adversely affect the investment levels and increase the economic problems. Fed decision to increase money supply can be propelled by several factors. First, an increase in money supply can be aimed at increasing the level of expenditure in the economy. By increasing the level of money supply, the government will increase the amount of wealth held by individuals. This makes them increase their expenditure to stimulate economic growth. Money spent in both consumption and investment will increase because of the increase in the disposable income (Floyd 63). Individuals will as well increase the proportion of their investments in bonds, as they will use the excess money to buy bonds and shares in the capital markets. Secondly, Fed can decide to increase the money supply to stimulate investments. An increase in money supply will result in a fall in the nominal interest rates, which will further result in the fall in the real interest rates. Due to t he fall in interest rates, the cost of borrowings will be reduced. Potential investors will therefore be encouraged to borrow and acquire capital necessary in pursuing their investment plans. Consequently, the increased investments will increase the level of employment because of the increased economic activities. Sometimes, the government through Fed can decide to increase the level of money supply to cause an increase the price levels by a desirable margin. According to the quantity theory of money, price levels depend directly on the money supply. In the long-run therefore, an increase in money supply will result in an increase in the price level by equal proportion. Fed can have this objective during the period of recession or depression when the level of economic activities is low to stimulate economic activities and increase the quantity of purchases. In addition, a decrease in the interest rates will increase the demand of the local currency hence cause depreciation in the cu rrency. This is because in an open economy, interest rates parity must always be preserved. This will cause the currency to fall with a further expectation that it will fall faster in the future. The depreciation in the local currency will make the cost of local goods cheaper and attractive thereby causing a surge in both the foreign and local demand (Floyd

Gender and Politeness in an ESL Language Academic Context Research Paper

Gender and Politeness in an ESL Language Academic Context - Research Paper Example Politeness made by non-native English speakers varies depending on the language background of an individual. This may be studied through ranking and contextualizing conditions. The use of semantic features is key in this analysis in the theoretical literature. There exists a correlation between native English speakers and non-natives. When it comes to politeness there is an evident perception of the high level of politeness among non-native speakers than native speakers. This is an indication of oversensitivity to semantic distinction forms. The hierarchy of politeness indicates that there should be different grammatical patterns emphasis when handling natives and non-natives in an educational environment (Leavell & Hong-Nam 2006). There are cultural values that still implicit in a composition of non-native authors. Through a review of four principles of and practices, the individualism of the non-native authors may be determined in terms of voice, critical thinking and peer reviews of the texts. A comparison of the findings made with those of native indicates a variation in politeness. The cultural approaches adopted by non-native speakers may not comport with the principles and practices in different ways. The cross-cultural writing research rationale leads to self-knowledge of non- native speakers. In writings done by non-native speakers, there are often inappropriate elements evident in the pieces of writing according to judgments made by teachers or lecturers who are native speakers. An analysis of essays written by non-native speakers supports the view that the aspect of politeness dominates among non-native speakers. The choice of words with unintended results does not depict rationality for readers. The advancement of factual claims in linguistics within the word sentence and beyond indicates politeness. Through a study that involves investigations on interaction styles, videotaped compositions for non-English native speakers was conducted. This was don e for consecutive weeks and the individual videotaped were met for interviews. This was done for Chinese and Spanish speaking students for comparison. A recursive examination of the patterns and themes in the language command and characteristics for the students was done (Atkinson & Ramanathan 1999). The Chinese scripts reflected a social goal while in maintaining harmony in the group. This included a high level of politeness in the group. The Chinese students always appear to be reluctant in initiating comments. At any point they made comments they appeared to be careful about making mistakes in their composition and speech. The monitoring of self-led to the evasion of criticism from peers who are native speakers. They also appeared to avoid disagreement with comments made by peers in the writing. The reason behind the position taken by non- native speakers is the lack of confidence among the students compared to other students who are native speakers. The Chinese students opt to u se polite words for acceptance among peers. The language learning strategy applied by students who are not English native speakers include the application of different linguistic backgrounds and culture. The key consideration is the interpersonal communication skills that encompass knowledge in cognitive academic language proficiency. There are differences applied across gender and nationality in becoming proficient in English. According to Snow, Met, & Genesee (2012), the use of metacognitive strategies and memory strategies aids in the learning process.     Ã‚  

The Light Emitting Diodes Engineering Essay

The Light Emitting Diodes Engineering Essay History of lighting devices starts with low efficient incandescent lamps, then next came the CFL lamp. In the history of lighting devices, invention of LED was a turning point Light Emitting Diode or simply LED is an electronic device, which emits light when electricity passes through it. LED has a number of different uses in day to day life. Its uses varies from a simple power on indicator to indicator to traffic signals. LED uses about 10% of the energy traditional light bulb uses and they can last about thirty times longer.LED lights are highly efficient and cost effective. Nano technology has its own role to play in lighting devices history. Invention of quantum dots and ionic liquids changed the face of lighting industry. Quantum Dots LEDs were manufactured using quantum dots particles. QLEDs offer better luminescence than normal LED lights. Introduction of Ionic Liquids (IL) was another turning point. Still in the beginning stage, Ionic Liquids offer a better solution to the world of lighting devices. 2. Light Emitting Diodes (LED) A Light Emitting Diode or LED is a semi-conductor device which can be used as a light-source. Semiconductors are neither a good conductor nor an insulator. Semiconductors are made up of semiconducting materials like Silicon or Germanium. A diode (also called as a PN junction diode) has two terminals, anode(a) and cathode (k), anode is a positive terminal and cathode is negative terminal- which allows electric current to pass only in one direction. A semiconductor diode can be compared to a switch or a one-way valve. A Light Emitting Diode emits light when electric current passes through it. The colour emitted by an LED depends on the type of semiconductor material used for its construction. Common colours available for LEDs are green, red, orange, blue, yellow and white. Aluminium gallium indium phosphide (AlGaInp) alloy is used for obtaining red, yellow and orange lights. Indium gallium nitride (IaGaN) is used for getting blue, green and white lights. White and Blue LEDs are more expensive than other colours. Apart from the above colours, Infra Red LEDS (also called IREDs-Infra Red Emitting Diodes) and Ultra Violet LEDs are also available. Staring into an Ultra Violet LEDS is harmful to the eyes. 3. Quantum dot LEDs (QLEDs) Quantum Dots are very small crystals, in nanotechnology terminology, they are nano particles of semiconductor materials, usually its diameter varies between 2 and 10 nano meters. Quantum dot particles were discovered in early 80s by Louis Brus at Bell Laboratories. A Quantum Dot can contain either a single electron or thousands of electrons. Generally quantum dots are made from the sulphides or selenides of semi conductor materials like Zinc or Cadmium. Quantum dots electronic and optical characters are related to the size and shape of each particles. When energy is applied (under excitation), electrons get energized and moved to higher bands, and when electrons get back to the stable state, the additional energy is emitted as light corresponding to a certain frequency. Its narrow emission spectrum is directly proportional to the size of the crystal. Smaller particles give a blue shifted emission and larger particles give a red shifted emission. Using a technique called size quantization effect, quantum dots can be tuned to produce any colour during manufacturing. Quantum dot LEDs (QLED or QD LED) are devices which use quantum dots as their light emitting material. These dots are excited when electricity is applied and emits light according to the size of the dots. Larger dots produce more energy levels and darker colours and smaller dots create smaller energy levels and emits lighter colour shades. Gold or silver nano particles are very versatile materials whose diameter varies from 1nm to 100nm. Gold nano particles are comparatively smaller that of Silicon Quantum Dots. And it s experimentally proven that, smaller particles generate better fluorescence than that of larger particles. So, Quantum Dot LEDs manufactured from gold or silver nano particles increases the luminescence. 4. Ionic liquids (IL) Ionic liquid is the salt form of any material in liquid state. Ionic liquids are liquid salts. Ionic liquids are made up of, ions (charged atoms) or ion pairs. These ions or ion pairs are poorly coordinated in the liquid. This poor coordination of ions results in the liquid from below 100 °C. Ionic liquids are also known as liquid electrolytes or ionic fluids. When a salt melts without decomposing, it results to an Ionic Liquid. Ionic bond is much more stronger than the bond between the normal Van der Waals forces in the molecules. Ionic liquid changes its form to ionic solid when it gets cooled. Ionic solids are seen in two forms, crystalline and glassy. At low temperature, ionic liquids acts like ionic solutions, which is a combination of both ions and neutral molecules. Ionic liquids are also called designer solvents, because they are manufacturing in the lab for specific purpose. Properties of ionic liquids are they dont evaporate, and it is a good conductor of electricity, and it dissolves almost everything. The reason for their non-evaporate property is their non-volatile nature. So, Ionic liquids can replace some acids and organic solvents. Ionic liquids are used for electro polishing, metal plating, extracting metals from rocks. Applications for Ionic liquids are storage for chemical cells, batteries, fuel cells and electro chronic devices for displays, cellulose processing, used as dispersants agents in paints, for gas handling and storage, for natural fuel processing, in food and bio-product industries, in recycling of plastic and synthetic wastes etc. 5. Turn-On Time Turn on time or rise time is the time required by a signal to change from low state to high state. The time it takes for the output of a system to change from a specified small percentage (usually 5 or 10) of its steady-state increment to a specified large percentage (usually 90 or 95).   (www.answers.com) An LEDs turn-on-time is the time needed by the device to turn from OFF state to ON state. Time needed to emit the light, after applying the electricity. LEDs are very fast devices and its turn-on time is 0.0001S or 0.1mS. Polymer light emitting diodes (PLED) uses an electro luminescent conductive polymer that emits light when connected to a power supply. PLEDs need very small amount of electricity to emit light and therefore they are considered to be very efficient. A polymer light emitting diode use ionic liquids as one its active material. Usually polymer light emitting diode has fast turn on time. 6. Improved Efficiencies in LED LED efficiency can be improved by paying attention on packaging, chip structure and positive voltage applying. White LEDs are usually considered to be more efficient that the other Red, Green, Blue colour LEDs. White light in LED can be produced in two ways. One method is, using three individual LEDs which producing the primary colours and then mixing them to produce the white light. Another method is, using the principle which is using in fluorescent lights, a phosphor material is used to convert light from UV or blue LED to white light. The luminous efficiency of blue/UV chip and the conversion efficiency of phosphorous determine the efficiency of white LED. Luminous efficiency is highly influenced by temperature and current. Efficiency of LEDs fall with the increasing current. This effect is called droop. When operating temperature increases from 327K to 380K, the luminous efficiency dropped by 20%. When the temperature is rising, the radiation at the potential decreases which eventually cause a decrease in luminous efficiency. When operating current rises from 0mA to 350mA, the luminous efficiency of LED tend to be decreased by 35%. When current increases, more and more non-stable electrons diffuse out of potential well, thus decreasing the luminous efficiency. We can improve the luminous efficiency of a LED by improving the heat dissipation efficiency and increasing the width of potential well. Working condition of a LED should be under limited temperature and moderate current. The heat generated in the LED, reduces the efficiency of lighting performance. A good packing technology is the way to solve the heat dissipation problem. But developing a heat dissipation technology for reducing the LEDs working temperature is a real challenge. The efficiency and reliability of an LED depends on the thermal dissipation of an LED, because the heat generated in the junction affect the performance and effective operation of LED. LED efficiency can be improved by LED packaging. But, we need to over come the challenges facing in packaging stage to reach the desired efficiency. The challenges facing in packaging are colour consistency of light emitting, multi-chip packaging etc. Packaging technology used for high power LED are more complex and costly. In addition to packaging, chip structure and positive voltage also play a role in LED efficiency. Efficiency can be achieved if positive voltage can be controlled in a very small range. 7.Studies of radiation damage in solar cells and LEDs Solar cells Solar cells or photovoltaic (PV) cells are devices which converts solar light to electricity. Working principle of a solar cell is just opposite to that of LED. A solar cell converts light to electricity while a LED converts electricity to light. In a solar cells, photovoltaic effect generates electricity. Solar cells are made up of semiconductor materials like silicon. When light hits on a solar cell, some portion of a light is absorbed by silicon material. That means, the energy in the light is shifted to the semi conductor material. This energy excites the electrons and make them to break the covalent bond, Breaking of covalent bonds in an atom results in free electrons. This free electrons start flowing and the flow of free electrons cause a current flow in the solar cell. A group of solar cells are electrically connected to form a frame called solar panels. A solar panels are grouped to form large solar arrays. When sunlight hits the semiconductor, the electrons from P-type semiconductor springs up and is attracted towards the N-type semiconductor. This make negative charges in the N-type semiconductor and more positive charges in P-type semiconductor. Thus electricity is generated due to the flow of electrons. This is called photovoltaic effect. Radiation damage Radiation damage is the physical damage occurs to devices (solar cell or LED) in a radiation environment. Visible light, also known as electromagnetic radiation, does not damage soalr cells or LED normally. But exposing to ultra violet (UV) light , which has more energy, can damage the cells overtime. Output parameters of the devices are affected by radiation damage. Radiation damage in solar cells and LEDs occur when highly massive particles like electrons, protons, or ions come in contact with semi conductor materials. The source of the highly massive particles may be nuclear reactions, gamma rays, space radiation etc. The particles having mass and energy can interact with materials in different ways, such as inelastic collision with electrons in a material, inelastic collisions with nucleus and elastic collisions with nucleus. Ionisation and atomic displacement are the two categories of radiation damage that occur to solar cells and LEDs. Ionisation : Ionisation is the process when an atom becomes an ion. It happens, when electrons lose from an outer orbit or extra electrons are added to atom structure. High energy radiation cause ionisation in materials. The use of silicon is solar cells and LEDs cause a range of ionisation related radiation effects such as increased leakage current, decreased gain etc. Atomic displacement : When a fast particles collide with a crystal, silicon atoms may get displaced from their lattice structure. And this displacement may damage the silicon solar cells. Silicon Solar cell damage There are different method to measure silicon solar cell damage. One method is by measuring the irradiation changes occurring in a solar cell and can be explained using basic solar cell equation. This method require data such as series resistance, shunt resistance, current generated by light and diode parameters such as saturation current and quality factor of diode. Solar cell damage can also be measured by observing the change in minority carrier diffusion length. And this method is widely used because diffusion length is measurable. But there are many disadvantage to this method. One serious disadvantage is damage caused due to low energy protons. Low energy protons do a significant damage to the PN junction of a solar cell. This irregular damage increases the saturation and quality factor of the diode. This damage can cause a significant decrease in voltage. The output parameters of a solar cell can be described using the formula Isc  =  Isc0  Ã‚  C  log (1 +  Phi  /  Phix)  , where Isc is the cell short circuit current Phix is the radiation fluence at which Isc starts to change C is the Constant indicates the decrease in Isc per decade The relation between solar cell short circuit current and diffusion length can be represented as Isc  =  A  lnL  +  B. Solar cells are more prone to radiation damage in space. The degradation of cover glass material of solar cell in space is more. Ionisation cause more damage to covering material than atom displacement. Ionisation in material are directly depend on the radiation absorbed. Solar cells are usually made up of Si and GaAs which are more prone to radiation. Replacing these semiconductor material with InP during manufacturing is the best way to reduce damage due to radiation. InP is more resistant to radiation that Si or GaAs. InP substrate constructed with high carrier concentration has superior radiation resistance. LEDs are also prone to displacement damage. Shorter wave length AlGaAs and GaAs LEDs emitting light in the region 800-900nm are more prone to radiation damage. Manufacturing LEDs with higher wavelength is the answer to this radiation problem. 8. CONCLUSION LED lights are widely using these days commercially. The main advantage of LED is its reduced power consumption. They are highly efficient, cost effective, durable and long lasting. Inventions like quantum dot and Ionic Liquids in Nano Technology field, bring significant changes in Lighting. Quantum Dot LEDS are more efficient than normal LEDs, QLEDs use nano crystals as their lighting materials. Use of gold or silver nano particles increases the luminescence emitted from the QLEDs. Introduction of Ionic Liquids, changed the appearance of LED lights. Ordinary LED lights produces a harsh white lights. Implementing a layer of ionic liquids to the LED light, produces a warm light. Researches were made to find the ways of improving the efficiencies of LED. When expose to space radiation solar cells and LEDs are more prone to damages. And it reduces the life span of these devices. Researches are still continuing in the field of nano technology, searching for finding new methods to improve the efficiency of lighting devices.

Networking Computers :: Technology Business

There are many kinds of networks, however this paper will be about networking computers. As we move further and further into the paperless society, the need for people to be connected and able to exchange data just as fast as they could by handing a paper to someone increases. This can be accomplished by having a group of computers connected by a network, so that as soon as data is entered into one computer, it can be immediately accessed by someone else on a connected computer, no matter how far away it may be (though usually it is in the same building). There is much work involved in this and it in includes a lot of math, from equations to basic problems. This report will be based around the mathematical aspects of setting up a network.The first mathematical question in setting up a network is very basic. How many computers will be connected to this network and how many guest computers might come on at one time is the question. An example of a guest computer is if someone brought a laptop and connected it for a short while to download or access data. To find the answer to the question, simply count the desktop computers that will be connected and how many guest computers you expect to be connected at one time. The second mathematical problem that occurs is best solved using an algebraic equation. Let x=the amount of desktop computers that will always be connected, y=the amount of guest computers that you expect to be connected at one time. So, the equation is: x+y+1. The one added on the end of the equation is another guest file just to make sure you don't fall short. So, this tells you how many files you need to create. The guest files will all be generically named so that all guests have the same access privileges, and all the permanent computers will have their own named file so they can have more personalized access privileges. These files are put on one main computer, the server. This controls all access privileges and any data put into a computer branching off from it in it's network can be accessed from this all-powerful server computer. The previously stated problems are a large part of networking, although I couldn't possibly tell about all the math involved without going on for another 3 or 4 pages.
