Free Essays on HardDrives

Nearly every desktop computer and server in use today contains one or more hard-disk drives. Every mainframe and supercomputer is normally connected to hundreds of hard-disk drives. Hard disks were invented in the 1950s. They started as large disks up to 20 inches in diameter holding just a few megabytes. Hard drives were originally called "fixed disks" or "Winchesters" (a code name used for a popular IBM product). They later became known as "hard disks" to distinguish them from "floppy disk drives". Hard disks have a hard platter that holds the magnetic medium, as opposed to the flexible plastic film found in tapes and floppies. The earliest true hard disks had the heads of the hard disk in contact with the surface of the disk. This was done to allow the low-sensitivity electronics of the day to be able to better read the magnetic fields on the surface of the disk. The very first production hard disk was the IBM 305 RAMAC (Random Access Method of Accounting and Control), in troduced on September 13, 1956. The RAMAC stored 5 million characters (approximately five megabytes, but a â€Å"character† in those days was only seven bits, not eight) on a whopping 50 disks, each 24 inches in diameter. Its arealdensity was about 2,000 bits per square inch; in comparison, today’s drives have arealdensity measured in billions of bits per square inch. The data transfer rate of this first drive was an impressive 88,000 bytes per second. Over the succeeding years, the technology improved incrementally; arealdensity, capacity and performance all increased. In 1962, IBM introduced the model 1301 Advanced Disk File. The key advance of this disk drive was the creation of heads that floated or flew above the surface of the disk on an air bearing reducing the distance from the heads to the surface of the disks from 800 to 250 microinches. In 1973, IBM introduced the model 3340 disk drive which is commonly considered to e the father of the ...

Economics for Business and Management - Essay Example Therefore, the invisible hand is that process where while an individual is pursuing self interest, he/she promotes the overall societal welfare but not intentionally. On the contrary, Smith says that he had never in his lifetime known the goodness of the persons who involved in trade to achieve the main goal of the public welfare. In his book â€Å"The Wealth Of Nations† Smith has only one stand, that the invisible hand is the prime determinant of the public welfare. (Suntum, 2005 pp1-5) Command and Mixed Economies A command economy, which is also referred to as a planned economy, is one which has the state regulating resources. The state is the decision maker to come up with the allocation or utilization decisions of the available resources. It uses the services of certified planners who are just below the state in power to implement these decisions. (economicwatch.com, 2011) A command type of economy is not without merits and demerits alike. The merits of a command economy m ay include the main fact that they ensure that collective interests for the public good are maximized. Also governments which do their operations under this type of economy are able to mobilize as well as respond swiftly to raise capital and commence the process of production if need arises. (businessspan.com, 2011) The demerits associated with a command economy are the likes of the denial of sovereignty for individuals as regards the expression, working, earning and making expenditure choices. It as well assumes that people should be fully committed to work and they should aim at overall national welfare. There is the demerit of slowness in ensuring economic growth unlike the capitalist type of economy. Equality does not thrive in a communist economy since there is stratification. Lastly, there is lack of flexibility when it comes to moving from one decision to another for the welfare of the public. On the other hand, a mixed market involves a blending of the two major types of eco nomy. That is, a command and a market type of economy. This is mostly the kind of approach by Italy, India, France and Sweden. Here, there is the government controlling of resources and the private sector. There are sectors in which distribution as well as production is under the state’s management. Sectors which have both the state and the private sector jointly involving in production and distribution and the sectors under which private control is in entirety. (Aswathappa, 2008 pp269,270) A mixed economy may be characterized by several advantages. Some of the advantages of a mixed economy are with the inclusion of the good regulation of prices in the market. Here, the state always ensures that prices do not soar above actual prices. It as well provides a level playground since there are private sectors involved in the market without compromising on the quality of commodities in the market. Natural resources are also optimally utilized due to there being the government and t he private sector being involved in the allocation. People in a mixed economy have ample power when prices and quality of commodities is put into consideration. Monopoly cannot also thrive in a mixed economy as both the private enterprises and the government gets their hands in every business. (benefitsandadvantages.com, 2010) Critics state that a mixed economy is not the best type of

Politics and Love in Contemporary Arabic Literature Essay - 1

Politics and Love in Contemporary Arabic Literature - Essay Example Adonis alludes that newness in Arabic society are identifiable with Arabic character. In the poem, ‘Love’ he depicts the feel of affection for the context he is in, like the road, house, the dead, the neighbors and the toiling hands of the world (Arana 120). The selected diction shows the high stakes in Adonis works, which invites every bit of creativity and intellect. He heightens the reader’s originality to new thoughts and realms that create curiosity. No, wonder his love for renewal and democratic consciousness won him the Goethe prestigious award. The reflection in the poem, ‘Celebrating Childhood’ affirms that the history of Arabic is not that of the sword but also lately made of great men. Lately, comments from Adonis on the political atmosphere in Middle East, especially in Syria that brought nothing good in the society except backwardness, bitterness, torture, and breakdown to the people, is a show of hi grip to the Arab politics (Arana 231). Kahlil Gibran is still a celebrated hero in Arabic literature context. In his Arab world, his incisive writings have earned him the tag of a political rebel (Gibran 65). Gibran works borrow a lot from the romantic styles of writing. The political events and power struggle do not make his daily life but through continual literary awareness of the situation in Lebanon, he asserts that the society is one place and homeland where all men are his fellow compatriots. The literal works of Gibran infuse the love of the society and advocacy for tranquility (Gibran 94). In ‘The Hands of Destiny’, he fascinates with the beauty of nature, and glamour that natures espouse. In this sense, Gibran aesthetic capture the literal world Lebanon ought to experience. He writes of the ideal nature that comes with spring and equates it to the Lebanon society. The reference of the beautiful spirit of Spring lingering in the atmospheres of

Criminal Justice System Essay Example for Free

Criminal Justice System Essay When defining crime it different from country or may be even states such as in the United State American, according to the law at hand. In this paper, one will learn the definition of crime as it applies here in the U.S.A in Its relationship to the law, and the two most common models of how society determines which acts are criminal. One will also describe the government structure as it applies to the criminal justice system. Then identify choice theories and their assumptions in regard to crime. Furthermore, describe the components of the criminal justice system and the criminal justice process. In addition, identify the goals of the criminal justice system. Last but not least, one will address one’s thought on if the criminal justice system is a system. Finally, one will summarize the conclusion in its entirety. According to (CJI Interactive, 2013) crime is defined as conduct in violation of the criminal laws of state, the federal government or local jurisdiction, for which there is no legally acceptable justification or excuse here in the U.S.A. This only means where one is located determine whether or not it is a crime. The most common models of how society determines which acts are criminal are consensus and the conflict. In one’s mind this leads to the description of both, consensus model has to do with diverse, people thoughts, most society whom shares the same moral value system. Most people think this system is deemed harmful to the society. On the other hand conflict also is consider diverse in many ways, however, this group engage in a much power struggle with most dominant groups that makes values about the law. The main thing is without laws people could not say that something is a crime. The government structure as it applies to the criminal justice  system consists of three branches of government: Legislature, Judiciary, and Executive in which the whole system work together in preventing crime in the U.S.A. However, there are the criminal justice system for each city or state, three basic department agencies within the every state the police, courts, and the department of correction. Each of the agencies is components that work together design, and structured to be fair, integrity, and professional. The federal government has standard guideline that affects every state. Furthermore, every state has its own guideline of the laws, and some may be different in every State. In the choice theories of people assumptions in regard to crime are consensus and conflict that explain earlier in the paper. The over important theories is Due Process and Crime Control. Due process consist of individualization, quality, formality courts. Crime control would consist of standardization, quality, informality, and police. Although they are both different in our society the completion between them if one fails either way with society fail the people. In other words they both system must work not to fail our society. The components of the criminal justice system and the criminal justice process consist of five main components are Investigation and arrest, pretrial activities, trail, sentencing, and corrections. These agencies in the criminal justice system work hand-in-hand together as a sequence process of events that le from the arrest to the correction. Together this is the standard process the criminal justice system use in the U.S.A. In all fairness most people thinks that is a fair procedure. The goals of the criminal justice system come in components as well. Most in people are very depending on whom one asks about this, in the people or justice system. According to CJI there are many of goals and different agencies within the system emphasizing the different goals. The role of the criminal justice system is to respond in the name of society, when crimes are committed. The five criminal justice goals are deterrence, incapacitation, retribution, rehabilitation, restoration. In addition there is a standard process in any city. Therefore, at the end of the day it is up to whether federal, state, or city decide on what is best for the  criminals. When it is all said and over with the most important reason is to rehabilitate people and make them whole again. In summarizing, when defining crime it different from country or may be even states such as in the United State American, according to the law at hand. One feels as if many people judge the system, however, one think it is there to help and restore us as one. Writing this paper helped one to gain and give knowledge of every day crime madness in the U.S.A as well as what is consider a crime here in our culture. One has learned many things as it refer to the topic in this paper and the major points that are important through research. References Dreden, E. (2013). The Structure of Criminal Justice System.

Identifying Lesbian and Mother :: Argumentative Persuasive Papers

Identifying Lesbian and Mother In her 1995 book, "On the Outside Looking In: The Politics of Lesbian Motherhood", Ellen Lewin presents the phenomenon of lesbian women who, through childbirth, gain access to the heterosexual community as an in-group member. At first glance, Lewin's observations seem to subvert traditional inside/outside ideology, portraying the boundaries of the hetero- and homosexual worlds as permeable rather than rigidly, relationally exclusive. A more exhaustive analysis, namely of the accounts of the women Lewin interviews, serves instead to reinforce inside/outside construction in relation to self and perceived identity. While the women are 'allowed' into the selective sphere of heteronormality, they do not cross these categorical lines as both 'lesbian' and 'mother'. This paper will argue that the terms 'lesbian' and 'mother' are mutually exclusive, perhaps not in reality, but in the capacities of identity, performance, and location within an inside/outside dynamic. Lewin prefaces her analysis with a glance at the classic Western representation of the lesbian. This depiction focuses on the exclusion of lesbians from typical female roles of "motherhood" and "nurturing"; being a mother carried an implied notion of heterosexuality, therefore, lesbianism and motherhood "cancelled each other out in the popular imagination" (107). Indeed, many of the women surveyed shared the sentiment of motherhood as "overwhelming and engulfing other dimensions of their lives—including what they considered the lesbian component" (109). While this may be ascribed to the daunting tasks of mothering and childcare, the women pointed to a more self-appropriated explanation as they echoed one another in their tendencies to "downplay the significance of their lesbianism in giving accounts of themselves [as mothers]" (110). Simultaneously, these women were rooting themselves more deeply in the heterosexual world and losing ties with the homosexual world. Many of the reports quote the lesbian mothers as feeling stronger ties to the world they share with straight women than with other lesbians. Many felt the lesbian community to be unfriendly to lesbian mothers. One woman was even asked to leave her all-lesbian rap group after her child was born, as her fellow group members believed she was no loner "attuned to lesbian issues" (124). The question remains as to why straight mothers, as a representation of the larger heterosexual community, would be so quick to ally themselves with lesbians, even lesbian mothers. For a scholar of feminist theorist Diana Fuss, this coalition seems to threaten the inside (read: dominant) status of heterosexual society.

Corrective Essay: Military Bearing and Respect

According to Field Manual 6-22, â€Å"Military Bearing is defined as having or projecting a commanding presence and a professional image of authority†. The United States Army is structured on several values and principles that it upholds, among these are military bearing, discipline and respect. Leaders should be able to make these big decisions with all his confidence projecting out with his military bearing. A leader should look like a leader, disciplined, confident, and has the skills and abilities to persuade and provide their subordinates with the motivation, direction and purpose so as to accomplish a mission without being easily rattled by problems that arises. The Three General Orders of a Soldier, The articles of UCMJ, as well as our own Soldiers Creed illustrates how a military service member should conduct himself or herself on a daily basis, on and off duty. Honor is to live up to all the Army values. Integrity is to do what is right, legally and morally. Be willing to do what is right even when no one is looking. It is our â€Å"moral compass† an inner voice. Army regulations and The Articles of the Uniform Code of Military Justice show us how a military service member should conduct themselves on a daily basis. Military bearing has many components that are involved such as self-discipline, discipline of others, taking appropriate actions for events or taskings, addressing superiors appropriately and dependability. Not just one thing can prove you have military bearing its takes being a professional and and a leader in all aspects of life to prove that you have military bearing. Self-discipline means that you have the ability to control yourself. If you do not have self-discipline you may be viewed as hot headed and unreliable. If you cant help maintain discipline of others it shows poor leader ship therefore making the unit from the lowest level to the highest level. Taking appropriate actions for events or taskings means that in the event that something bad happens contact the chain of command and the appropriate authorities so the situation can get handled. Dependability is a major aspect of military bearing. Without dependability, one can neither perform properly in the workspace nor be depended upon by their coworkers, or chain of command to carry out their military duties adequately. A military member is required to be punctual, and reliable. Duty requires a willingness to accept full responsibility for your actions and for your subordinate's performance. It also requires a leader to take the initiative and anticipate requirements based on the situation. Duty means accomplishing all assigned tasks to the best of your ability. The proper and faithful performance of duty is the standard. The value and efficiency of the soldier is measured, and the measure of his efficiency and value is not determined by the prominence of the duty which he performs. Military bearing is to conduct yourself with dignity and in such a manner to reflect credit upon the armed services. Military bearing exists when this individual is proud of their military service. When you exhibit military bearing you are showing lower enlisted soldiers how to act and giving them an example to follow. Knowing how to properly march, stand at attention, parade rest, as well as all other facing movements establishes one’s ability to follow orders precisely. A lot of self-discipline comes with having good military bearing, which explains and reinforces the necessity to have it. Not everyone has good military bearing. Military bearing and respect are something that you have to work on and maintain control of, you can earn it but if you do not work on a maintain control of it then you will lose the respect or bearing you may have earned. Having good military bearing means you are tactful and polite while also being neat in appearance and can carry out the highest level of professionalism. It's very important to follow directions, or else the world would be in chaos. Respect, especially in the Army is a very important value to live by. It is much more than just talking kindly and listening to someone. It is the process of taking into consideration someone’s emotions, feelings and needs. It is showing someone that you value their time; that you care what they have to say. Behavior and attitude will allow the person demanding respect to feel that respect. When we respect each other, there are fewer conflicts. Respect is not only shown verbally, but also by one’s behaviors and actions. If someone you respect asks you to do something, you should do it immediately and without hesitation. You should do it quickly. Earned respect builds a stronger relationship between people, can be more specific then demanded respect, and is more stable than demanded respect. Also, true respect must be built on experience, and therefor it is illogical to instantly demand it. Earned respect builds a stronger respect and a stronger relationship between people. So you should always be respectful to others so they will treat you the way you want to be treated.

Classical Conditioning and Behavior - 2385 Words

Behaviorism Summary: Behaviorism is a worldview that operates on a principle of â€Å"stimulus-response.† All behavior caused by external stimuli (operant conditioning). All behavior can be explained without the need to consider internal mental states or consciousness. Originators and important contributors: John B. Watson, Ivan Pavlov, B.F. Skinner, E. L. Thorndike (connectionism), Bandura, Tolman (moving toward cognitivism) Keywords: Classical conditioning (Pavlov), Operant conditioning (Skinner), Stimulus-response (S-R) Behaviorism Behaviorism is a worldview that assumes a learner is essentially passive, responding to environmental stimuli.

The implications of Watson’s experiment suggested that classical conditioning could cause some phobias in humans. Social Learning Theory [ref: Ormrod, J.E. (1999). Human learning (3rd ed.). Upper Saddle River, NJ: Prentice-Hall.] Social learning theory focuses on the learning that occurs within a social context. It considers that people learn from one another, including such concepts as observational learning, imitation, and modeling. Among others Albert Bandura is considered the leading proponent of this theory. General principles of social learning theory follows: 1. People can learn by observing the behavior is of others and the outcomes of those behaviors. 2. Learning can occur without a change in behavior. Behaviorists say that learning has to be represented by a permanent change in behavior, in contrast social learning theorists say that because people can learn through observation alone, their learning may not necessarily be shown in their performance. Learning may or may not result in a behavior change. 3. Cognition plays a role in learning. Over the last 30 years social learning theory has become increasingly cognitive in its interpretation of human learning. Awareness and expectations of future reinforcements or punishments can have a major effect on the behaviors that people exhibit. 4.
