Nuclear Energy Should Be Continued The use of nuclear energy should be allowed to continue for many reasons such as nuclear energy is cleaner and safe when handled properly. An example of where nuclear energy is cleaner than other forms of energy such as coal-burning is in how the energy or heat is produced in the plants. In nuclear power plant the energy or heat it produced by the fission of Uranium; in a coal-burning plant the burning of coal produces the energy or heat. The Uranium power plant

Operating System | Assignment #1 | | Information System | 2012-03-29 | | 1. What is the purpose of interrupts? What are the differences between a trap and an interrupt? Can traps be generated intentionally by a user program? If so‚ for what purpose? (Chapter 1) Interrupt is that causes a computer processor to temporarily stop executing its current program and execute another program instead‚ finally returning control to the original program. So it prevent that more important task

You are the network administrator for a new company that has 10 users and plans to add five more users within a year. The files need to be accessed by all 10 users and each user must have different security rights. What kind of network would you install and how would the pieces and components of this network relate to each other? Define

Components of an Operating System In order to perform the actions requested by the computer’s users‚ an operating system must be able to communicate with those users. The portion of an operating system that handles this communication is often called the user interface. Older user interfaces‚ called shells‚ communicated with users through textual messages using a keyboard and monitor screen. More modern systems perform this task by means of a graphical user interface (GUI) in which objects to be

Why did men continue to fight in WWI? The Great War was fought between 1914 until 1918. It took the lives of millions of men and it is said to have had horrible conditions‚ the question still remains. Why did men continue to fight in the Great War? Was it because of their discipline in the army? Did they fight because of their friends in the army? Or were the conditions in the trenches not as bad as people say they were? This essay will argue that‚ even though all of these reasons were very important

Linux evolved into a fully functioning Operating System (OS) with one of its first distributions created by the Manchester Computing Center‚ MCC Interim Linux‚ using a combined boot/root disk (Hayward‚ 2012). Linux luminaries‚ Slackware‚ RedHat and Debian began to rise between 1992 and 1994 as well as the Linux kernel growing to version 0.95‚ becoming the first kernel to run the X Windows System.

Mainframe/PC Evolution The evolution of mainframe computing to personal computing began with the invention of the mainframe for businesses and government use. The Personal Computer (PC) evolved from companies wanting the same information from scaled down version of the mainframe and dumb terminal. Though they both consist of data storage‚ processors‚ input and output devices. However‚ they have their differences. Mainframes The mainframe was invented in the 1950’s. One of the first mainframes

History of Operating Systems Early computers lacked any form of operating system. The user had sole use of the machine; he would arrive at the machine armed with his program and data‚ often on punched paper tape. The program would be loaded into the machine‚ and the machine set to work‚ until the program stopped‚ or maybe more likely‚ crashed. Programs could generally be debugged via a front panel using switches and lights; it is said that Alan Turing was a master of this on the early Manchester

2.1 TYPES OF OPERATING SYSTEM A. Batch Operating System- Batch processing is the most primitive type of operating system. Batch processing generally requires the program‚ data‚ & appropriate system commands to be submitted together in the form of a job. Batch operating systems usually allow little or no interaction between users & executing programs. Examples of such programs include payroll‚ forecasting‚ statistical analysis‚ & large scientific number-crunching programs. Serial processing combined
