What are the differences between an interrupt and a trap? What are their importance? According to Stallings (2012) an interrupt is “a suspension of a process‚ such as the execution of a computer program‚ caused by an event external to that process and performed in such a way that the process can be resumed” (p. 716). Stallings (2012) goes on to say that “interrupts are provided primarily as a way to improve processor utilization. For example‚ most I/O devices are much slower than the processor”

Since the inception of computing‚ the binary digit (bit) has been used to encode information at the lowest level. Why? … How efficient is this process‚ and are there any ways of optimizing it? The bit is the most primitive data type of the computer. It is often represented with 1 or 0. In this discussion‚ we will explore reasons for choosing the bit as the lowest level encoding. We will also discuss how it can be efficiently stored‚ transferred and executed. Finally‚ we will examine ways to optimize

May 16‚ 2013 Benoit Mandelbrot Born on November 20th‚ 1924 in Warsaw‚ Poland‚ Benoit B. Mandelbrot was a French and American mathematician known for developing the “theory of roughness” in nature as well as fractal geometry to prove his theory. . Mandelbrot asks“Can geometry deliver what the Greek root of its name [geo-] seemed to promise—truthful measurement‚ not only of cultivated fields along the Nile River but also of untamed Earth? Mandelbrot’s father bought and sold clothes while his mother

don’t just belong to evaluators or the evaluation plan. As the term suggests‚ they are a basic element of programming that communicates the logic behind a program‚ its rationale. A logic model’s purpose is to communicate the underlying "theory" or set of assumptions or hypotheses that program proponents have about why the program will work‚ or about why it is a good solution to an identified problem. Logic models are typically diagrams‚ flow sheets‚ or some other type of visual schematic that

What impact will an unanticipated increase in the money supply have on the real interest rate‚ real output‚ and employment in the short run? How will expansionary monetary policy affect these factors in the long run? Explain. “In the short run‚ shifts in monetary policy exert an impact on real output and employment. A shift to a more restrictive policy will tend to reduce real output and employment‚ while
