System Administration/ CIT Q2: Suppose you have two hard disks (sda,sdb) and sdb has already been partitioned to sdb1 and sdb2. Create physical volumes using the whole sda and the two partitions of sdb. Create a volume group that contains a complete sda disk and one partition on another disk . create two logical volumes ( a small one and a bigger one) in this volume group . Format all logical volumes with ext4 and mount them. Extend the volume group. Extend only one logical volume. -You have to suggest the size of each hard disk and also make sure to give the appropriate size for each logical volumes. -Do not forget to use commands that check each step you do . The answer of the second question is only acceptable if you write it by your hand.

Assignment/Lab 9 In this lab, your task is to develop a simple address book tool. The tool maintains contact information of people. For each person, the tool maintains name and date of birth. Contact information consists of physical address and phone number. For physical addresses, the system must be able to maintain current and previous addresses. Current/active address information should have starting date and no end date, previous addresses must have a starting date and an ending date. A person cannot have multiple active physical address. For phone number, the system must maintain active phone numbers only, no previous phone numbers. For implementation, use MySQL database system. MySQL is open source and is available for Linux as well as Windows. For software application, use Python. The tool/application must support the following functionality: 1- Search current contact information by last name, the user enters last name, the system must locate active physical address and phone…

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…

In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap? A. The data section B. The .text section C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory. Reset Selection

Instructions  Your job is to write a program to encrypt outgoing messages and decrypt incoming messages using a Vigenere Cypher.  In this assignment, you will parse a string of words from a file into tokens using the strtok_s command with pointers and then use the Vigenere Cypher algorithm to encrypt and decrypt the parsed words. Before you can perform any encryption/decryption activities, the first step is to read in messages from a file and parse the messages into individual words. The Program:  Setting up classes and understanding tokenization The first step in encrypting/decrypting messages is to parse the messages into words before applying the encryption/decryption algorithms to them.  This parsing process is called “tokenization.” Read the contents of a file into this array using the getline command.   The objective of this assignment is to demonstrate the use of pointers in a program utilizing c-strings and tokenization.  The use of pointers is foundational in C++.  This…

Compute total no of blocks} Consider a file of 8192 records. Each record is 16 bytes long and its key field Is of size 6 bytes. The file is ordered on a key field, and the file organization is unspanned. The file is stored in a file system with block size 512 bytes, and the size of a block pointer is 10 bytes. If the primary index is built on the key field of the file, and a multilevel index scheme is used to store the primary index, number of first-level and second level blocks in the multilovel index are the respectively 16 and 1 b. 32 and 1 16 and 2 8 and 1 c. d.

3. Using Pool0 do the following: 3.1. The pool must have 2 processes, each process will pass two parameters to a search function, these parameters must be the name of the file and a word to search for, these two parameters must be entered by the user and must be different from the process to another. The Search function must search for the word in the file and if the word is found then find out the number of occurrences for this word otherwise return that the word doesn't appear in the file. 3.2. 3.3. You need to verify that the file the user input is actually a file and it exists in the system.

WRITE 2 C FILE In this assignment you are required to follow the Unix domain server and client example done in the classroom. After this point, you need to setup the server in a way that it will process the data sent by the client and send back the processed data. You must read at least two set of data, and send back at least a piece of information. For instance, client might send two numbers and the server will send the summation back. This is only an example, please do something a little more complicated. I do not want to see same operation over and over again in the assignments. You can use scanf and printf with dup2 to obtain numbers. Alternatively, you could read the text and use sscanf and sprintf. You could also perform text based operations. It is up to you. You must perform all error checks.
