The issue: There is no shortage of creative solutions for accelerating construction. They have all kinds of justifications for why their favourite concept will enable you to finish a five-day project in 3.8 seconds. Consider the -pipe option in the gcc compiler. The first pass of the compiler is typically executed, and the result is written to a temporary file. In the second pass, this file will be read and a second temporary will be written. until the required number of passes have been made. Every pass is executed simultaneously when the -pipe option is used, with the output of one pass' output linked to its input by a pipe. According to the hypothesis, by doing this, you may completely eliminate temporary files and disc I/O for them by performing everything in memory. Therefore, the -pipe option must speed up processes. The option is used in the kernel Makefiles, so if we still needed more persuasion, it must be a good choice since the Linux kernel uses it.

For this assignment, you must implement the Data Encryption Standard (DES) algorithm with any programming language that you are comfortable with. The recommendation is to use C/C++ or Java. You can accomplish this assignment individually or by forming a team of 2 students. You can utilize the publically available tables/functions in order to implement the DES. You can find these permutation tables/functions in some reference books or over the Internet. You algorithm should get a plaintext as well as a "secret key" from the user and then perform encryption (generating the ciphertext from the plaintext) and decryption (generating the original plaintext from the ciphertext). You can also select any "mode of operations that you want. All the necessary technical materials are available in the posted lectures on Canvas. You must submit all related files in a zip file on Canvas (just one file for each group, submitted by the group leader). Make sure to include a "ReadMe.txt" file so that I…

Please write in C++ and run in linux. This assignment is about fork(), exec(), and wait() system calls, and commandline arguments. Write two C++ programs, to be named parent.cc and child.cc and compiled into executable parent and child, respectively that, when run, will work as follows: parent takes in a list of gender-name pairs from the commandline arguments creates as many child processes as there are in the gender-name pairs and passes to each child process a child number and a gender-name pair waits for all child processes to terminate outputs “All child processes terminated. Parent exits.” And terminates.   child receives a child number and one gender-name pair arguments from parent outputs “Child # x, a boy (or girl), name xxxxxx.”                  Note: content of output depends on data received from parent   Sample run To invoke the execution: >parent girl Nancy boy Mark boy Joseph parent process does the following: outputs “I have 3 children.” -- Note: the number 3…

Question No: 06 This is a subjective question, hence you have to write your answer in the Text-Field given below. Consider P0,P1,P2 are three processes synchronised with semaphores S0=1,S1=0,S2=0 as shown initialised. The table below gives the code of the processes Process PO While (true) { Process PI Process P2 Wait(S2); print 1"; signal(S1), wait(S1); signal(S1); wait(so); print *0"; signal (S1); signal (S2); a If the sequence of processes schedule is P1,P2,P0,P0,P2,P0,P2,P0. What are the values printed? b. If the semaphores are initialised with S0-0,S1=1 ,S2=1. What are the values printed for the above sequence?
