- There are many different kinds of digital memory that may be used, such as cache memory, hard disc drives (HDD), random access memory (RAM), solid state drives (SSD), and others. Cache memory is used to store frequently used data. The use of computers makes all of these things available to the user. Is it beneficial to have a variety of standards, or would it be more convenient for customers if there was only one memory standard, with the exception of varying sizes of solid-state drives (SSDs)? If having numerous standards has any advantages, what exactly are those advantages? Is there any advantage to having a wide variety of standards to choose from? If there was just one standard that needed to be adhered to, would that make things easier and more economical for customers?arrow_forwardComputer science What are the Advantages of Partitioning?arrow_forwardWhat does it mean by "entries" in this context? I still do not understand why sorting is not needed. If we sort all the books according to the publisher name, wouldn't it be faster to count how many books are pulished by each publisher? The answer states we need a "counter", but when you go through the entries for each of the keys, don't we need to have 30 counters in total? (each counter is associated with one pulbisher. In other words, when a book pulisher matches with one of the keys, shouldn't it increment the counter variable associated with that pulisher?) Please clarify questions reagrding the answerarrow_forward
- There are a number of advantages to using both logical and physical partitions on the same machine.arrow_forwardIn what ways are horizontal and vertical partitions different?arrow_forwardIt is not possible for other parties to directly access data storage. When drawing Data Flow Diagrams, there are a few rules that must be observed. Is there any importance to this order?arrow_forward
- 3. I/O Management: Disk Arm Scheduling & RAIDa. It is known that a disk drive has 256 cylinders, with cylinder numbers starting from 0 and ending at 255. The position of the needle on the disk drive currently stops at 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. From the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.i. SCANii. C-SCANiii. FIFOarrow_forwardIt is advised that you make use of a computer that has both physical and logical partitions. These are only a handful of the many benefits; there are many more.arrow_forwardSimply clicking on this link will allow you to get more knowledge on a memory hierarchy. It is not quite obvious why the creators of your work concluded that a pyramid would be the greatest graphical portrayal.arrow_forward
- me remaining: 00:09:34 Computer Science Create a MPI version of the program below that uses a striped decomposition. Each process is responsible for some number of columns of the square and also maintains two columns of ghost cells to mirror the columns on the neighboring processes. The ghost cells are needed in order to update the cells along the process boundary. At each time step, a ghost cell exchange takes place, then the update takes place. #include <stdlib.h> #include <assert.h> #include "anim.h" const int n = 200; // number of discrete points including endpoints int nstep = 200000; // number of time steps int wstep = 400; // time between writes to file const double m = 100.0; // initial temperature of rod interior const int h0 = n/2 - 2, h1 = n/2 + 2; // endpoints of heat source const double k = 0.2; // diffusivity constant char * filename = "diff2d.anim"; // name of file to create double ** u, ** u_new; // two copies of the temperature function ANIM_File…arrow_forwardIt is preferable to work with a computer that has logical partitions in addition to physical ones.
