Hardware Components Essay

There are several types of hardware storage devices invented and designed to facilitate encoded and retrieved data storage in computers. Some of the examples of these storage devices include the ff. : the hard disk, floppy disk, RAM, CD ROM, and tape. Furthermore, these storage devices together with hardware component of clock speed play their distinct roles to determine the speed and speed rate of a computer (MSD, 2006). Body First, introduced in 1956 and developed during 1973, by the IBM company, the hard disk, or â€Å"hard disk drive† as mentioned, is one example of a stable and reliable secondary hardware storage device that efficiently facilitates speed. It functions as some kind of an optimal and purposeful storeroom which saves accumulated and encoded numeric and digital data, and it is also appropriate for running application programs on spinning magnet-plated platters that is performed by execution and command by the user. Hard disk drives were created for personal computer usage. It has features like audio playing, video gaming, video recording, etc (MSD, 2006). Second, the role of hard disks in determining the speed of a computer is very significant because with the use of hard disk, it can makes the access of files easier and faster as it runs or rotates. The bigger the platters or dishes used by the hard disk to run, the faster its speed and the smaller the platters, the lower the capacity of the computer to run, work, or access files faster. The number of disks in a specific computer may vary at a minimum number of 3 disks to a maximum number of 5 running disks revolving 60 per second. Most hard disk drives make use of removable cartridges while some do not. Most people create back up from the files they saved from the disk since the recent hard disk is created with such a sensitive feature. It can store data from 20 M up to 40 M (MSD, 2006). Third, a floppy disk coming in two sizes: 5 ? and 3 ? inches, is a detachable or unfixed storage device which is already obsolete. It is secondary as compared to the huge capacity of hard disk when it comes to data storage memory. The uses of floppy disks though, become popular for it is much cheaper than the cost of a hard disk. Moreover, it is more convenient to carry floppy disks wherever you go and save data for the use of backup purposes. Moreover, floppy disks make use of the delicate, magnetic and bendable disk which is film-like in color and enclosed in a protective plastic shield or case. The roles of floppy disks portray no role in determining the speed of a computer—speed is determined by the Central Processing unit and its memory rather. For practical reasons, hard disks are favored over floppy disks especially when the cost of the first (hard disks) becomes more inexpensive than the latter. Further, floppy disks are really essentially slower and more sensitive than hard disk that is why it is more prone to damage (MSD, 2006). Fourth, random access memory (RAM) is the primarily appropriate for storage of data that occurs in the computer’s memory and is stored directly at the computer’s Central Processing Unit (CPU). The two types of RAM are the SRAM and the DRAM. SRAM stands for Static RAM and the latter meaning, Dynamic RAM (DRAM). With the use of RAM, user can program the CPU to read, write, and locate data. The role of RAM is to carry out and execute calculations at high speed which is made possible by the said feature of RAM or computer memory that operates random to locate items or applications in the computer system (MC, 2008). Fifth, with the use of compact disks, the CD-ROM operates and exemplifies the use of read-only memory for sharing and sending applications like music files, games, and other multimedia files and desktop applications. The capacity of CD-ROM when it comes to data storage is up to 650 M. Recently, CD-ROMs tend to be much cheaper than other storage devices. CD-ROM is appropriate for expansion of one’s personalized computer system. In addition, CD-ROM does not play a role in determining the speed of a computer. In fact, user retrieves data slower than any other available data computer storage device in the market if the computer is not supported by CD-ROM’s â€Å"data transfer speed (MSD, 2006). † Sixth, tape is a thin strip of plastic, magnetic coated device used mainly for recording and it is known to be appropriate for secondary data storage or backup. Moreover, this tape is most appropriate for the purpose of calculations or â€Å"personal computing. † There is a no role that a tape plays in order to determine speed in a particular computer; further, data access is slower than expected together with its inconvenience for the required retrieval of data in orderly and chronological manner (MSD, 2006). Lastly, clock speed—as measured in megahertz (MHz), is the â€Å"speed of the internal clock of microprocessor. † Clock speed is appropriate for functioning in operation in the internal processing of a computer. The clock speed plays an important role in determining the speed of a computer and it affects the overall performance of the computer (MSD, 2006). Conclusion Several types of hardware storage devices are invented for data storage in computers: the hard disk, floppy disk, RAM, CD ROM, and tape. All mediums except for the floppy disks, CD-ROM, and tape play a role in determining the speed of a computer. These devices except for the other three are hardware components that determine the speed and performance of a computer.

International Political Economy - Essay Example It also mentions some of the conditions that countries need to fulfill in order to receive any assistance from the organization. Composition of the IMF Executive Board, Voting powers The member states have the liberty to participate in the IMF directly. The executive board comprises of 24 members out of which five executive directors can be elected by the member states having the maximum quota. The remaining nineteen executive directors are elected by the remaining number of members. The powers that each country enjoys are predominantly dependant on the proportional scale of their population and the economic position they hold in the entire world. The general owners of the organization are represented by the board of executive directors who are responsible for taking the major decisions and responsibilities of the organization. However, all of the names of the member countries are represented in the economic scale. This is more resembling with the theory of structuralism which was di scovered and presented by Marx. In the view of structuralism theory presented by Marx, it disputes the instrumentalist theory which considers the state as being the direct servant of the ruling class or the capitalists. Structuralism theory states consider the capitalist of production as the state being under the control of the capitalist class having superior powers. As per the members of the executive board, it is seen that members having superior positions in the IMF are actually the members who belong to the developed nations of the world which abides by the structuralism theory stated by Marx. The highest decision making authority of IMF rests with the Board of Governors. All powers of the IMF are vested in the Board of Governors. The Board of Governors comprises of a single governor as well as an alternate governor for each of the member countries. Members’ states are responsible for appointing the governor and generally the finance minister or the governer of the Centr al Bank is nominated for the position. The Board of Governors may delegate to the Executive Board all except certain reserved powers. The Board of Governors generally conducts a meeting in every year (IMF, â€Å"IMF Members' Quotas and Voting Power, and IMF Board of Governors†). The regular or day to day running of business of the organization is done by the Executive Board. Composed of 24 Directors, either elected or appointed by the member nations or also by collective groups of countries, it is also elected by the Managing Director, or the Chairman of the board. Several meetings are conducted by the Board in a single week. The works are generally conducted by the papers which are prepared or provided by the management and staffs in IMF (IMF, â€Å"IMF Executive Directors and Voting Power†). Design and operations of IMF In the 1980s a tremendous financial crisis had gripped the Latin American economy when high and bloated public debts and improper and loose monetary policies had led to very inflation rates in the economy. However, some of the conditions set by the IMF demonstrate the fact that it imposes certain restrictions or preconditions before providing aid to nations. For example, in this situation, the International Monetary Fund gad imposed financial austerity or balanced budgets as well as tighter monetary policies. The IMF demanded from the nation that it should impose the same monetary policies

Argument in favor of Holistic Therapy for Lung Cancer Patients Essay

Argument in favor of Holistic Therapy for Lung Cancer Patients - Essay Example The holistic therapy focuses on five aspects of life that contribute to persons’ sense of well being, namely physical, social, spiritual, emotional, and intellectual (St. John, 2009). To have a better understanding of the benefits and advantages of CAM over conventional medicines (specifically chemotherapy), three arguments will be created to support Holistic Therapy. Chemotherapy is a method of treatment wherein anticancer drugs are administered to the bloodstream usually via IV infusion, with some that can be taken by mouth. The treatment not only affects rapidly multiplying cancer cells but also has adverse effects with healthy multiplying cells (Rothenflue, 2010). Focusing on the chemotherapy for lung cancer, the treatment has inherent side effects that can cause temporary as well as permanent damage to the patient. This side effect includes the reduction of healthy blood cells that lead to vulnerability to infections, bruises and bleeding, and the constant feeling of weakness and fatigue. It may also permanently damage the cells in hair roots; even if hair grows back after treatment, the color and texture would be different. The anticancer drug can also harm the cells in the digestive tract that leads to loss of appetite, nausea and vomiting, diarrhea, or mouth and lip sores. Side effects become even worse when radiation therapy is taken at the same period (Rothenflue, 2010). For the first argument, it is evident that conventional medicines are detrimental to the physical and emotional well-being of the patient. The invasive nature of chemotherapy makes holistic therapy more appealing to cancer patients, with current studies indicating that increasing number of cancer patients have undergone at least one alternative treatment. The most common CAM treatment is the use of vitamin and mineral supplements, which is intended to strengthen the patients’ immune system and to

Theories on crimes Case Study Example | Topics and Well Written Essays - 1250 words

Theories on crimes - Case Study Example Harvey Robinson was a teenager serial killer who killed and raped Charlotte Schmoyer - another fellow teenager- in 1993, he also assaulted numerous women. According to Ramsland (2012), there was evidence of blood and abandoned shoes where it was later discovered that the girl had also been stabbed in the woods. In committing the crime of rape and murder, Harvey had gone back to the scene of a previous crime scene when he chanced upon Charlotte who was the ‘perfect’ victim in an isolated place. Serial killers who rape and kill are a rare kind as evidenced by the involvement of the FBI in most of the cases. This theory explains the prevalence of criminal behavior in that the criminal makes rational choices when committing crimes. The reasons behind committing crimes could be due to personal needs like anger, lust or greed. This theory basis its ideas on the classical school of thought in criminology, which posits that individuals have a free will to choose their actions both good and bad while threats of punishment and sanctions deter criminal acts (Siegel, 2009). Furthermore, the choice theory points out that there are three actors of criminal behavior; rational actor, predestined actor, and the victimized actor. For rational actors, there is a choice on whether to commit a criminal act which is manageable with an imposition of penalties. The predestined actor commits crime without any control over their desire and surroundings. These actors are stimulated before they commit crimes. In order to enhance deterrence, there is a need to change the psychological, social, and biological environment. The victimized actor appears since there are disparities in the society; this ought to be addressed through enacting laws. The choice theory is useful in explaining the crimes given that Robinson stalked other victims then he made rational
