    Explain the Way in Which You Would Establish Ground Rules with Your Learners, and Which Underpin Behaviour and Respect for Others.

    Having explored the three methods of setting ground rules during session 2 of PTTLS course, it is evident that for the ground rules to be effective, determining the appropriate method of ground rules setting is crucial to informing how the learners will be likely to respond to the ‘ground rules’ and how this will later affect the session or sessions to be delivered.…

    Personal Philosophy Of Teaching

    Even though I may not find myself in the classroom setting teaching everyday, I have learned that I possess the power to transform lives inside and outside the school setting. I firmly believe that some of the best teaching occurs beyond the classroom and within everyday moments. Some of the best educators I have had in my life were not just teachers but instead were people that walked along side me in life. These people educated and inspired me in ways that could not be taught within a textbook. Each educator that I have had within my life has molded the philosophy of which I believe we should teach and inspire others with. My philosophy is very different from most educators because I believe that the best…

    Operating System Comparisons

    An operating system (OS) is software that manages the hardware and software resources of a computer system. Basically an OS is a set of libraries or functions which programs may use to perform specific tasks relating to interfacing with computer system components (The Computer Technology Documentation Project, n.d.). Advantages and disadvantages exist in every operating system. Reviewed in this paper is a comparison of some of the primary responsibilities of popular operating systems. Although Microsoft Windows has taken its own approach as an operating system, Mac OS X is based heavily on the UNIX core. The review includes Unix/Linux, Mac OS X, and Microsoft Windows operating systems.…

    Evolution of Computers

    This development stretched within five generations. Each generation follows a common thread in computer design and functionality – decreased size and increased speed. The evolution of computers is greatly influenced by the innovations and development in field of electronics. New technology in the field of electronics are assimilated and adopted in the design and development of computers. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices.…

    paging implimentation project

    Background The basic function performed by a computer is execution of a program, which consists of a set of instructions stored in memory. The processor does the actual work by executing instructions specified in the program. In its simplest form, instruction processing consists of two steps The processor reads (fetches) instructions from memory one at a time and executes each instruction. Program execution consists of repeating the process of instruction fetch and instruction execution The processing required for a single instruction is called an instruction cycle consist of two steps, the fetch cycle and the execute cycle. Program execution halts only if the machine is turned off, some sort of unrecoverable error occurs, or a program instruction that halts the computer is encountered. To improve processing efficiency, the concept of interrupts is used. Virtually all computers provide a mechanism by which other modules (I/O, memory) may interrupt the normal processing of the processor. With interrupts, the processor can be engaged in executing other instructions while an I/O operation is in progress. For example, most external devices are much slower than the processor. Suppose that the processor is transferring data to a printer using the instruction cycle. After each write operation, the processor must pause and remain idle until the printer catches up. The length of this pause may be on the order of many hundreds or even thousands of instruction cycles that do not involve memory. Clearly, this is a very wasteful use of the processor. In this project, multiple nested interrupt are being discuss and the program build are meant to this type of interrupt but somehow the program can also work for multiple sequential interrupt based on how priority of interrupts are set. Later I will discuss how multiple interrupts are being served by operating system and how sequential and nested multiple interrupt are differs. 1.1 Objectives…

    Principles of Effective Teaching

    In my research I learned that there is no simple definition for principles of effective teaching. As we all know learning is a challenge and change in each individual. In an effort to summarize principles of learning a handful of ideas come to mind. Communication, Interaction, Diversity Recognition, Program Knowledge, Teaching Techniques, Student Exercises, and Appropriate Breaks. Learning is more likely to occur if there is a realistic and attainable learning goal.…
