...CPU and I/O Burst Cycle * The execution of a process consists of a cycle of CPU execution and I/O wait. * A process begins with a CPU burst, followed by an I/O burst, followed by another CPU burst and so on. The last CPU burst will end will a system request to terminate the execution. * The CPU burst durations vary from process to process and computer to computer. * An I/O bound program has many very short CPU bursts. * A CPU bound program might have a few very long CPU bursts. Histogram of CPU-burst Times Types of Scheduling * The key to the multiprogramming is scheduling. There are four types of scheduling that an OS has to perform. These are: * Long Term scheduling * The long term scheduling determines which programs are admitted to the system for processing. Thus, it controls the level of multiprogramming. * Once admitted, a job or a user program becomes a process and is added to the queue for the short term scheduling (in some cases added to a queue for medium term scheduling). * Long term scheduling is performed when a new process is created. * The criteria used for long-term scheduling may include first-come-first serve, priority, expected execution time, and I/O requirements. * Medium-Term Scheduling * The medium-term scheduling is a part of swapping function. This is a decision to add a process to those that are at least partially in main memory and therefore available...

...My interest in pursuing a position as a school administrator for an elementary school system is to provide leadership for staff members and quality education for all students, and to become part of the world of education. The Benjamin Franklin School located in the Dallas School District serves as a growing population of approximately 1,070 students. The school offers a well-defined educational system for the students, and it has an overall student-to-teacher ratio of 17:1. In addition to the statewide curriculum standards, the school offers special education programs and classes for the gifted and talented. As a result of the school district rankings in the student’s performance, Benjamin Franklin School has become the worst in the district which has caused stereotyping among teachers and students. Based upon strategies planning efforts to ensure the school fosters an atmosphere where all are respected, I would like to work toward creating a positive environment where students feel valued, and supported by their teacher. I will assess data to measure students learning and improve leadership skills that value every student at Benjamin Franklin School to increase achievement. The progress toward the goal will report better performance ratings. While focusing on the many challenges of becoming an administrator, I need to focus on classroom management and improving student’s motivation to learn.

...Zenmap Specs * Supported Operating systems: Windows, Mac, Linux, BSD * Cost: Free * Requirements: Nmap Who’s it for? Zenmap is for any network or security administrator who needs to keep a constant check on their network topology. With it’s next-to-zero learning curve, just about any network administrator can have all of the information they need quickly. Zenmap will work for any size company or even a single-user consultancy, where a quick scan of a network topology can make the difference between spotting a security issue and finding a resolution or, well…not. What problem does it solve? There are two very key issues Zenmap solves. One is making the more-challenging Nmap scanner useable for the average administrator. Nmap is a console-only tool and the majority of administrators do not want to spend their day at the console (with a nod to the old-school Linux and UNIX admins who would much rather spend their day at the command line than in a GUI tool). Zenmap also gives the administrator a topology mapping tool where they can actually see an interactive, animated visualization of the hosts on your network. Key features * Free * Easy-to-use GUI * Quickly saves scans * Uses traceroute and ping * Saves profiles for frequent run tests * Topology mapping * Compares scan results of different scans * Runs multiple scans and views them as one big scan * Plenty of default scan profiles to choose from * Searches scan results...

...hard economy nursing homes have to make cuts, and unfortunately they are cutting all in the wrong places. Many times office jobs in the nursing home are the last to be cut and the nurse aides are the first to be cut, and the reason being is because many states do not have laws stating the aide to resident ratio. Today, a local nursing home has just got a new hope in recovering the problem of the loss of success that their nursing home has encountered. They have begun to cut nurse aides and have begun to run the halls short-handed, unfortunately their complaints have went up and their residents have become very unhappy.

An effective leader steps up to fill in holes as needed, even if it isn’t a part of their daily routine. Being a school principal is balanced between being rewarding and being challenging. It is a difficult job and like any job there are people that are just not cut out to handle it. There are certain characteristics of a principal that everyone is not equipped with. Besides the obvious professional requirements needed to become a principal, there are several traits that good principals must possess to effectively do their job. Each of these characteristics manifests themselves in the daily duties of a principal. The best principals possess each of these seven qualities. A principal must exhibit leadership. This is a characteristic that every principal must possess. The principal is the instructional leader of their building.

...Essay for My Chosen Career Essay for My Chosen Career Throughout this paper I would like to discuss the required steps to achieving my chosen career as a Network Administrator. The decisions I make during my time in school will have a great impact in my success. Training: Enrolled in ITT-Tech I have made the decision to further my education and pursue a path to a new career. Having this opportunity has opened a door that has been closed to me for a long time. Taking on this responsibility I must complete all assignments on time and get good grades in my academics. After being approved to enroll in college next came the burden of financing my education as well as maintaining my personal finances. First I spoke with a loan officer to get approved for any Loans and/or Grants that I may qualify for. Then for my personal finances I’ve found ways to cut down on my spending, save as much as I can, and live within a budget. Last but not least is to find time for my classes and schedule time for homework and assignments. Keeping a planner makes it easier to keep track of my daily activities and schedule my appointments around my class schedule. Another way I can have extra time is to keep my vehicle in good running condition and keeping it current and up to date. To me the only way to earn a higher level of income is to obtain a higher level of education and continued education. If you are thinking that you would like to further your career and increase...

...SOUTHWESTERN UNIVERSITY GRADUATE SCHOOL OF HEALTH SCIENCE, MANAGEMENT AND PEDAGOGY MPA 504 Reflection Paper on How to Become a Better Public Servant (Teacher) Ria P. Pachica Dr. Angelina C. Villareal (Student-Iloilo Group) (Professor) Introduction I come to education later in life and with a passion. I did not expect that I would have a second career. I volunteered in a kindergarten class for a few hours a week to be generous to the community. Quickly, I discovered that I was the one receiving the gift. The children were extraordinary; exciting, challenging, and loving. Her teachers and the other teachers I met at her school were extraordinary as well. Their caring, professionalism, and openheartedness moved and inspired me. Reasons for Wanting to Become a Teacher I believe that teaching is an essential and noble profession. Next to parents, teachers are the most important foundational element in our society. Everything important begins in childhood, especially knowledge, self-knowledge, resilience, and character. Proper preparation is fundamental to living a full, rewarding life. Without self-knowledge, children may follow wrong paths and end up far from their true callings; lost, sad, and unfulfilled. Without resilience, the storms and challenges of life can turn children from their highest path, leaving them far from who they might have been. Finally, character is the intangible force that raises society as a whole, minimizes...

...My Dream Job I guess my dream job would be a combination of things. I don’t like just sitting at a desk. I need to get up and move around. I guess it would be a helpdesk role along with a systems administrator and a network administrator. I enjoy working with people hence the helpdesk role. I like the freedom to move around of the helpdesk role. Network administration is the most challenging of the roles. System admin is probably the most mundane of all. The helpdesk requires you to go to a person’s desk and interact with them. In the network admin role you work with the different devices. You may have to troubleshoot a connectivity issue, install a device, and configure the device. In the system admin role you mostly create user accounts, set shares and permissions, create e-mail accounts. To be able to land this type of job I will have to update some of my credentials. Probably go to college for at least an associate’s or maybe a bachelor’s degree. A lot of job advertisements I am seeing are requiring those now. I have experience but no degree. I need to renew my CCNA certification. That entails either going to classes or studying online. Going to classes would be the best because it would go toward a degree and give some hands on experience. The same applies to my A+ certification. Some of the other certifications also need refreshing. At my age I wonder if it would be worth the effort of working toward a degree. It would take over two years to complete...

The other departments to consider would be those of finance and operations management as they too are a fundamental part of the organization’s decision making framework.

These features and functions are tied firmly to computer programs for end users as well as those for system administrators. Databases for keeping and maintaining all the information within the system are also of prime importance during the implementation stage. It is therefore imperative that the group of professionals from the Information Technology department, more so the system developers bear in mind the usability of the system so as to ensure they generate the correct types of computer software for application within the system. The standards and procedures to use during the development of system software on which the new automated human resource management structure would be based depend entirely on the keen...
