Let the processes P1, P2, P3, and P4 be given. They arrive in thesystem at the same time in this order. The processes have thefollowing service times (in time units):ProcessService time(CPU burst)P153P217P368P4242) For the scheduling method "Round Robin" (RR), specify theaverage execution time (average turnaround time) and the number ofcontext switches. The time quantum q is set to 20 time units. Youmust show your calculations. You will not have to draw Gantt charts.Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3-P4).

JAVA Task, by using ArrayList The program reads manatee names from the standard input stream and from time to time prints a sorted portion of the list of names. All the manatee names in the input are given in the order in which the necropsy was performed. You can imagine a unique timestamp associated with each necropsy. The names are not necessarily unique (many of the manatees have the same name). Interspered in the standard input stream are queries that begin with the question mark character. Queries ask for an alphabetical list of manatee names to be printed to the standard output stream. The list depends only on the names upto that point in the input stream and does include any manatee names that appear in the input stream after the query. The list does not contain all the names of the previous necropsies, but only a selection of them. A query provides the names of two manatees, say A and B. The response to the query drops necropsies performed before the first named A and all the…
1. why is debugging with a storage dump the most ineffficient of the brute-force methods? A. It contains program actions between the time of the dump and the time of the error that can mask the clues needed to find the error. B. It shows the program state at all times for error detection and for studying program dynamics. C. it sets breakpoints that cause suspesion in the program so that the programmer can examine the current state of the program. D. It requires a change of the program and such changes can mask the error, alter critical timing relationships, or introduce new errors. 2. What is a best practice for bug tracking? A. A bug item note/entry is unnecessary for every failure found during testing. B. Bug tracking is the responsibility of QA rather than development. C. Bug tracking is required to manage analysis and resolution of issues found throughout the development process. D. Bug tracking is only required during the UAT phase of testing in order to document user…
The method to compress an image in image processing is using convolution matrix where the number of outputs is reduced by replacing the matrix multiplication with much smaller kernel matrix. This is illustrated on the figure below. In this example a black and white photograph is scanned as a rectangular array of pixels and then stored as image matrix on the left by assigning each pixel a numerical value in accordance with its gray level, (0 = white to 255 = black), then the entries in the matrix are integers between O and 255.Then multiplication is employed with much smaller kernel matrix in the middle. 0|0 21 00 o 106 85 71 1 250 231 127 63 1 250 252 250 209 56 1 250 252 250 250 83 Kernel 0 0 0 Feature map Image Boxes in red and blue frames indicate how the upper left element is formed by applying the kernel to the corresponding upper left region of the input matrix. The elements of much smaller "feature map" matrix on the right can be calculated from: 3.
