1:34 b a 2. Different operating systems use different file allocation techniques to store files in the secondary storage device such as HDD. One of the techniques is "Linked allocation". In this technique, each file is divided into several data blocks of same size. Each data block has a link to its next block like a singly linked list. So, the data blocks are scattered on the disk. The directory contains a pointer to the starting and the ending data block of a file. The diagram below depicts a sample linked allocation system of a file Abc.txt: Directory entry File Start End Abc.txt 100 900 Data 900 Data Data block 1 block 2 Data block 3 block N Write a Java program to implement the linked allocation of a given text file Assgn1_2.txt (uploaded with the assignment) who's each block will contain maximum 50 characters. Read the content of the given file and store it in data blocks (maximum 50 characters per block). Now show a menu that will ask the user to i) add new content at the end of…
Figure below shows the index allocation structure of the Unix Inode (File Control Block) where 15 pointers are used to refer to the file blocks. The block size is 4KB and 4 Bytes are used for a pointer to a block. What will be the size of a file that uses all the file blocks up to the last block in the "double indirect blocks"? mode owners (2) Meta Data timestamps (3) size block count 12 pointers direct blocks single indirect double indirect, triple indirect UNIX FCB 48KB + 4MB + 4GB 12KB+ 4MG + 4GB O 4GB O 4KB x 4MB x 4GB
1. In indexed file allocation method, assuming that the block can only store 8 pointers as shown in the figure (see attached file) , what happens if the file needs 10 pointers? Give the advantages and disadvantages of this method. 2. What could be the advantage/s and disadvantage/s of using the following free space management schemes: a. Grouping b. Counting
5. Assume a file system is using combined indexing scheme to keep track of the blocks allocated to a file, as in Linux/Unix file system. In the inode of a file, there are 12 direct pointers, one single-indirect pointer, one double-indirect pointer, and one triple-indirect pointer. Assume the size of a disk block address (i.e., disk pointer size) is 8 bytes. Assume block size is 4 KB. a) What is the maximum file size? b) How many index blocks are required for files of size 30 KB, 256KB, 15 MB, 512 MB, 32 GB? c) Assume nothing is cached (no disk caching applied in the system) and we know the disk location of the inode of a file of size 1 GB. How many disk accesses are required to access a byte at offset 2^14 (16K) in the file? How many disk accesses are required to access a byte at offset 2^26 in the file?
A file whose file descriptor is fd contains the following sequence of bytes: 3, 1, 4, 1, 5,9, 2, 6, 5, 3, 5. The following system calls are made:lseek(fd, 3, SEEK_SET);read(fd, &buffer, 4); where the lseek call makes a seek to byte 3 of the file. What does buffer contain after the read has completed? I guess the answer is 1,5,9,2, but I'm not sure. Please tell me the detailed steps ,thanks

You are implementing a simple file system for an operating system for managing files and folders; similar to Windows or UNIX. Your design should follow the following guidelines i) The entire file system is represented by an object which is the reference to the root folder ii) Any folder in the file system may contain two types of items, folders (subfolder) and files and you want to treat both in the same way iii) possible operations: getName, getPermission, listItem What is the most appropriate design pattern? Draw the class diagram, and make it clear what are the main components and what are their roles, and show the relationship between classes? write code of the main components in your design? Note : this is a design Pattern Question Use java To solve this question please I need a fast good answer.Thanks a lot in advance.
Suppose you are working with R and you find your current working directory by running the following: getwd() [1] "/Users/netID/Documents/stat385" Additionally, assume the tidyverse has been loaded. library("tidyverse") Also suppose that within this directory, there is a folder named data that contains files named: • X.csv y.csv Z.csv Assuming properly formatted CSV files that the relevant R functions are able to parse, which of the following creates a tibble? read_csv("x.csv") read_csv("data/z.csv") read_csv("data/a.csv") read_csv("/Users/netID/Documents/stat385/x.csv") read_csv("z.csv") read_csv("/Users/netID/Documents/stat385/data/z.csv") read_csv("/Users/netID/Desktop/stat385/data/x.csv") read_csv("y.csv")
The standard library function int fseek(FILE *fp, long offset, int origin) is identical to Iseek except that fp is a file pointer instead of a file descriptor and the return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.
