Initial considerations:

Normally, the E-book shop contains a variety list of books from which the customers places an order based on their favor.

The following architecture is not the absolute design for “e-book reader” architecture. It is the assumption and it includes variety of classes to follow the inheritance property.

Primary classes and methods:

The primary classes and the methods of E-book reader that the java software required are as follows:

“E-bookshop”, “Customer”, “Order”, “ItemOrder”, and “Item”.

E-bookshop contains the methods getDownloadURL() and getsizeMB().

getDownloadURL() is used to download the site of the book that the customer needs to purchase.

getsizeMB() is used to know the size of the book in bytes.

Customer class contains the method Customer()

This method is to retrieve the details of customer.

Order class contains the method Order().

This method places the shipping details of order.

ItemOrder class contains the method ItemOrder()

This method used to get the number of order that the customer wants to place before purchasing.

Item class contains no method but is generalized into three sub classes such as Book, MusicCD, and Software.

The Book class contains the method Book() which is used to order the specific book based on author name.

The MusicCD class contains the method MusicCD() which is used to order the CD’s based on the artist collections.

The Software class contains the method Software() which is used to download the book based on the version.

A3Q3.c - You are to write a C program that implements the following disk scheduling algorithms: a. FCFS [10 marks] b. SCAN [10 marks] c. C-SCAN [10 marks] d. SSTF [10 marks] e. LOOK [10 marks] f. C-LOOK [10 marks] • Your program will service a disk with 300 cylinders numbered 0 to 299. • • • • The program will service the requests (a list of 20 cylinder numbers) given in the file request.bin. This file contains (4 byte) integer values representing requests ranging from 0-299. Your program will take the initial position of the disk head as the first command line argument and the direction of the head as the second command line argument. It will then output the requests in the order in which they are serviced, and the total amount of head movements required by each algorithm. In particular, your program needs to do the following: Your program should take two command line arguments a) First command line argument - initial position of the disk head (an integer value) b) Second command line…

2. The memory management has contiguous memory allocation, dynamic partitions, and paging. Compare the internal fragmentation and external fragmentation for these three approaches. [2 marks] 3. Suppose we have Logical address space = 24 = 16 (m = 4), Page size=2² =4 (n = 2), Physical address space = 26 = 64 (r = 6). Answer the following questions: [4 marks] 1) Total # of pages ? 2) Total # of frames ? 3) Number of bits to represent logical address? 4) Number of bits to represent offset ? 5) Number of bits to represent physical address? 6) Number of bits to represent a page number? 7) Number of bits to represent a frame number / 4. What is translation look-aside buffers (TLBS)? Why we need them to implement the page table? [2 marks] 5. Why we need shared pages for multiple processes? Give one example to show the benefits.
