Computer systems - Essay Example Software enables the computer to perform the computing functionalities and performing numerous tasks. Computer software entails system software (the operating system and all utilities that enable computing functionalities), applications software (these are programs that assist the users to perform specific tasks such as word processors, spreadsheets, database management system).Computer systems handle the execution of instruction through selection, iteration and sequencing a set of instructions. They execute binary instructions; hence, any kind of instructions given to the computer must be first converted into binary form (number base 2) before any computing action takes place (Blundell, Khan, Lasebae, and Jabbar, 2007). The advancement of digital technology has enabled the development of complex computing systems in the recent decades to encounter the changing and dynamic needs of the processing and dissemination of information in various organizations. There has been an improvement in the functionality and processing powers of computing machines lately and this has enabled vast quantities of information processing and storage. Computer systems have evolved from the older mainframes, which were bigger in size with low processing speeds, to now personal computers, which are smaller, cheaper, efficient, and easily portable. The tasks performed by the humans have been taken by computer systems that have increased the speed and efficiency of performing various tasks within a short period due to their multitasking nature (computers can perform various tasks at the same time). The operating systems of computers have been designed in a way that allows numerous tasks to be accomplished, and individuals can switch between tasks without waiting for any of the tasks to be completed (Dhotre, 2009). Monitoring The medical field has employed computer-monitoring technology on the functionality of the human body. The human body produces heat because of the metabolic activitie s that take place in the living cells. Modern thermograph machines are used to detect heat changes in the body; they convert such pulses to thermo grams fed into the computers, which are used to give images of the body parts that are unusually hot and cold. The images are used to investigate such defects as arthritis, breast cancer. Medical imaging is a technique that is used by physicians to observe the internal organs and functioning of the body. Imaging enables detection of causes of illness; such techniques include X-rays, magnetic resonance imaging, ultrasound, and tomography. They send beams of waves into the body and later receive the reflections from the body. Computerized tomography uses extensive scans from different angles and sends to the computer, which arranges the images. Magnetic resonance imaging uses magnets and radio waves to form images. A computer analyzes the radio waves coming from the patient to produce a detailed image. Ultrasound scans pressed against the b ody, relay waves into the body and receive back the waves, sends them to the computer, which processes an image on the screen, is used especially on pregnant mothers to detect the position and the overall development of the baby in the womb. Electrocardiographs are used to record signals originating

Peer review process - Assignment Example This is a very useful proposal for educational institutions since the factors that affect XYZ are the same factors that influence other institutions that offer the same services. I appeal for funding because management hired fire captains based of their technical competence and high motivational attitudes. However, this does not necessarily translate in to leadership ability, as many would think. Further, I think promoting managers that have not been trained, nor have had the opportunities to be mentored by experienced leaders, leaves an experience gap between upper level management and lower level supervisors that will soon be asked step into upper level leadership positions. It is significant to note that as upper level management leaves and younger supervisors step up there will certainly be a lack of transformational leadership and vision that was possessed by the leaders that left. Therefore funding such a project will improve leadership styles in organizations. The proposal has critically looked at the firefighting career field, which is technical field where firefighters are given individual tasks in order to accomplish an overall objective. When there is an emergency each individual knows what he or she as an individual must due to contribute to the team success of the mission. However, this causes problems when a firefighter is now put in the position of supervisor and they must keep up with the technical competencies of firefighting while also managing the administrative, political, and human resources issues that comes along with the day-to-day activities of running a fire station. In making this transition, one is often required to alter their paradigm or worldview. I appeal for funding for this project because the emphasis on efficiency, customer-service, and consistent communication are all-important components of an HRPP. Building trust between the research community and the HRPP indirectly serves as a
