Optical Disc Storage – Computer Science Essay (100 Level Course) Free Online Research Papers Optical Disc Storage Computer Science Essay (100 Level Course) An optical disc is a storage media consisting of a flat, round, portable disc made of metal, plastic, and lacquer. Optic disc are written and read by a laxer. Different formats of optical disc are CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD+RAM. Optical drive(s) usually are a standard feature on today’s personal computers. Users can read but not write or erase a CD-ROM, which stands for compact disc read-only memory. Users record their own items such as text, graphics, and audio on a CD-R, (compact disc recordable). You can write on a part of the disc at one time and another part at a later time. Oce recorded, a CD-R can be read from as many times as necessary. However, each part of a CD-R can be written only one time. The disc’s contents cannot be erased. You need a CD recorded or a CD-R drive to write on a CD-R. On the other hand, a CD-RW, a compact disc-rewritable, is an erasable disc you can write and rewrite multiple times. Reliability of the disc tends to drop, however, with each successive rewrite. To write on a CD-RW disc, you must have CD-RW software and a CD-RW drive (Manzanera Brautigam 14-20). A DVD-ROM is extremely high-capacity optical disc that stores 4.7 GB to 17 GB. DVD-ROM means digital versatile disc-ROM or digital video disc-ROM. The goal of DVD’s is to meet the needs of home entertainment, computer usage, and business data and information storage with a single medium. DVDs store huge databases, music, complexes, software, and movies. You must have a DVD-ROM drive or DVD player to read a DVD-ROM. Newer DVD-ROM deives also can read audio CD’s, CD-ROMs, CD-Rs, and CD-RWs (High Capacity Storage Media). To write on DVD-recordable or DVD-rewriteable disc, you must have the proper type of drive. DVD-R and DVD+R are competing DVD-recordable formats. Each has 4.7 GB of storage capacity. Both allow users to write on the disc once and read it many times. DVD-RW, DVD+RW, and DVD-RAM are competing rewritable DVD formats. DVD-RW and DVD+RAM allow users to erase and record more than 1,000 times. DVD+RAM allows users to erase and record on a DVD+RAM disc more than 100,000 times (Guzman Padilla). Encarta Dictionary. English (North America). 14 Sept. 2005. Microsoft Word Online Research.

Implementation of electronic road pricing is needed in Hong-Kong. To Essay

Implementation of electronic road pricing is needed in Hong-Kong. To what extent do you agree with this view - Essay Example For example, the electronic road pricing (ERP) system adopted in Hong Kong to manage traffic through congestion charges. Hong Kong pioneered use of ERP in the 1980s with great success. With few advancements in technology in the 1980s, ERP was implemented through use of an in-pavement reader and a transponder that was placed under vehicles. Adoption of ERP in Hong Kong solved the problem of congestions and charge evasion that faced manual road pricing. However, soon after adoption of ERP followed its critics thereby derailing advancements and over the years the project remained dormant until later propositions on its use rose again later. This was attributed to the fears that traffic problems would rise again in the Central and Wan Chai areas of Hong Kong. Therefore, the roads and transport administration made the recommendations for ERP system to resume operations. However, with time a new administration that was opposed to use of ERP took over thereby derailing ERP system once again. ERP is mainly applied in areas where there are high congestion levels and there is a functional public means of transport in existence. Existence of a public means of transport is to offer an alternative to road users who abandon use of personal vehicles. Therefore, ERP may arguably be considered a method of encouraging use of public means of transport as opposed to individual transport means. Efficiency of ERP depends heavily on its application to only areas with high traffic levels and a functional public means of transport since its application in many areas would arguably strain the system. For example, in Hong Kong ERP would only be most efficient in the Central, Wan Chai, and Causeway Bay. Charging periods are highest during peak hours and lower during off peak hours. Peak hours are determined by the economic advantages relating to different times of the day therefore the most economically

The Invasions of Europe Essay Example for Free

The Invasions of Europe Essay On the later stage of the dark ages or the Middle Ages, Europe experienced loses from barbaric attacks by Vikings, Magyars and Moslem invaders which ranged from early 9th century up to 11th century. These invasions had made Roman Empire lost most of its land area as well as the trust of people to the Christian leaders. Vikings started their attack because of overpopulation in their homeland. They came first to England then to Iona, Ireland and the rest of the north and western part, destroying the most civilized part of the region and plundering the rich trading centers and monasteries. As each attack became successful, they would return in more numbers. Their invasions had become easier on them because they had their sail ships compared to their earlier invasions which was by foot. People started fearing to live in the coastal region. While some of the Vikings battle in the western half of Mediterranean, some began settling in the northwest of France and the others came to Moslem Spain and Great Britain. Chieftains would bribe them in order for Vikings not to attack their villages. Some groups such as Danes began the resistance and successfully defended England. As Normans settled down, they began to decrease in number. They became civilized and were converted to Christianity. They had lost their lust in plundering. During that period, in the other part of Europe, the Moslems had gone invading Spain, threatening Italy, droving out Byzantines in Sicily and southern Italy. They almost got into Rome. While Moslems continued their attack in the Mediterranean, Magyars began invading the east. These groups of invaders which simultaneously attacked from all sides had surrounded the European continent. Magyars invaded Germany each year. They had passed through Germany, France, Burgundy, all the way to Italy. While some of them continued to pursue their attacks at France, others left for Spain. Until the Magyar armies were annihilated by a German king Otto I, Europe became safe from invasions.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   All of these invasions had contributed to the downfall of the rich Holy Roman Empire. But they experienced the worst attack from the Magyars mainly because during that time that they attacked, Europe was already suffering from attacks of Vikings and Moslems. There were almost no civilized regions left during that time and areas became less populated. They invasion became so damaging as they suffered simultaneous attacks from all sides.   As the Roman Empire tends to collapse, they failed to resist these attacks earlier because they had fewer warriors.   Some locals burn their fields not letting the barbarians have it. Most of the richest parts were prone to attack while monasteries were heavily subjected to being destroyed. People suffered heavily. They lost their lands, livelihood and their wealth. As they mourn, they ran to the church for comfort but they were disappointed as there were anomalies in the leader of the churches.   Some of them became robbers, adulterers, and murderers and converged into realms of politics. There were numerous replacements of popes. At a time there were â€Å"illegal doings† in the papal palaces. Some must have lost their trust in their belief. Yet, Christianity did not end there. It was reformed by Benedictine monks in France. As the Magyars were defeated during that time, they became converts to Christianity and settled at Hungary. Vikings were also converted to Christianity but one of the main reasons is that Christians didn’t want to trade with and marry non-Christians. During the latter course of Dark Ages, Europe gradually recovered from the invasion. Leaders were crowned but had conflicts with Christian leaders. There were tensions between them about who had the greatest power. And so the Dark Ages ended. References Kimball, C. (2001). Chapter 7: The Viking Era. A History of Europe.

It is in the early hours of Monday morning when Holden returns Grand Central Station. He decides to sleep on one of the benches in the waiting room because he has nowhere else to go. He wakes around nine, as the hustle and bustle of the working day begins. He thinks about the night before and the incident with Mr. Antolini; he wonders if he has misinterpreted Antolini’s touch. Disturbed by these though, he tries to think of something else. He reads a magazine someone has left behind. It is some kind of health magazine, however, and Holden gets more depressed, certain he has cancer and is dying. Holden decides to go out and buy himself an inexpensive breakfast. He does not want to spend too much of Phoebe’s money. Since his stomach is upset, he just drinks coffee. He leaves the train station and walks out to Fifth Avenue. All around him, people seem to be in the Christmas spirit, which is depressing to Holden. He begins to imagine he is disappearing, becoming invisible. He thinks the distance it takes to cross the street keeps growing and fears he will never reach the other side; it is like a death dream. He then begins to talk to his dead brother, asking him to help him cross the street. Each time Holden makes it across another street, he thanks Allie.

An Explication Of William Carlos Williams’s “The Red Wheelbarrow” Essay

Usually, in interpreting a poem, one simply relies on the metaphors behind the words to find a meaning. Sometimes, however, the structure of the poem itself and the literal image which the words convey are already the meaning of the poem. The significance in the reading of William Carlos William’s poem, â€Å"The Red Wheelbarrow†, lies in the structure by which the poet arranges the words and the snapshot of the image which the poem describes. The entire poem comprises of a single sentence cut into parts and stacked so that it becomes a four-stanza poem, each stanza of which comprises of two lines. The first lines are irregular; those in the first and fourth stanzas are made up of four syllables. The two sandwiched stanzas are only comprised of three syllables. Meanwhile, all second lines in each stanza are single words with two syllables each. As a sentence, the poem would be insignificant both for its mundane subject matter and lack of metaphor: So much depends upon a red wheelbarrow glazed with rain beside the white chickens. It becomes a subject for careful scrutiny, however, because of the manner by which the poet cuts the sentence into parts. The line breaks, cutting off whole words into two, suggest cued halting in the reading and the reader is forced to take in every image which every word evokes, both as a cut-off piece (i. e. wheel and barrow) and as a compound (i. e. wheelbarrow), slowly, part by part, then as a whole. The reader also learns to appreciate the painting which is the poem, like he does when viewing a still-life—a captured image intensified by the rendering—from a master artist, framed on a wall. The impact of the entire poem rests on the first stanza, â€Å"so much depends/ upon† (lines 1-2). It suggests the importance of what are to follow. It appropriates the value of the simple objects that would be enumerated. The placement of the word â€Å"upon† (line 2) as a line by itself, connotes the gravity of the importance of the wheelbarrow which is the central image in and subject of the poem. The word â€Å"wheelbarrow† is cut into two parts, â€Å"wheel† as a part of line 3 and â€Å"barrow† as an entire line 4. With the separation, the reader is forced to examine the machine by parts, the wheel first, before taking in the whole machine. His visual sense is also arrested with the middle word, which is a strong and bright color: red. The fifth line â€Å"glazed with rain†, gives the red wheelbarrow a character. It is not just a bright red wheelbarrow. It is dulled by the rain. It is a used and beaten implement. It has to withstand the natural elements. This reinforces the theme of attributing significance to this everyday object. This wheelbarrow does a lot of farm work, helping the farmer move and carry soil, manure, produce, etc. The same visual stimulus is presented again with the line â€Å"beside the white† (line 7), the adjective separating the noun, the â€Å"chickens. † (line 8), which the color pertains. Ending the line with another color, and one that contrasts sharply with the first color mentioned in the preceding stanza, makes the two objects captured in the painting (which is the poem) stand out against each other. The red wheelbarrow stands out against the white chickens. As an imagistic poem, â€Å"The Red Wheelbarrow† presents a snapshot of a farm scene. A red wheelbarrow sits idly on the ground, wet with recent rain, while chickens gather beside it, unmindful of the machine. The scene is ordinary and so is the description. The snapshot, however, perceived alongside the words and the form by which Williams creatively arranges the words, become more exciting because it begins to approximate a painting of an ordinary scene that is made special by the careful attention, reinterpretation and presentation of the poet. It is not just an everyday rural image of a wheelbarrow glazed with rainwater beside the white chickens. It is a work of art showing the image of a wheelbarrow glazed with rainwater beside the white chickens and the perceiver is being asked to evoke whatever associations, sentiments, feelings and interpretations he might come up with, both subjective and objective, as result of his experiencing the work of art. Reference: Williams, Williams Carlos. â€Å"The Red Wheelbarrow. †
