AND Operator: An AND operator accepts two inputs and produces a single output. If both the inputs are CLOSE, then the output is ON. Otherwise, the output is OFF.

: The Multithreaded Cook In this lab, we'll practice multithreading. Using Semaphores for synchronization, implement a multithreaded cook that performs the following recipe, with each task being contained in a single Thread: 1. Task 1: Cut onions. a. Waits for none. b. Signals Task 4 2. Task 2: Mince meat. a. Waits for none b. Signals Task 4 3. Task 3: Slice aubergines. a. Waits for none b. Signals Task 6 4. Task 4: Make sauce. a. Waits for Task 1, and 2 b. Signals Task 6 5. Task 5: Finished Bechamel. a. Waits for none b. Signals Task 7 6. Task 6: Layout the layers. a. Waits for Task 3, and 4 b. Signals Task 7 7. Task 7: Put Bechamel and Cheese. a. Waits for Task 5, and 6 b. Signals Task 9 8. Task 8: Turn on oven. a. Waits for none b. Signals Task 9 9. Task 9: Cook. a. Waits for Task 7, and 8 b. Signals none At the start of each task (once all Semaphores have been acquired), print out a string of the task you are starting, sleep for 2-11 seconds, then print out a string saying that you…

Question

Chapter 1, Problem 4P

Program Plan Intro

AND Operator:

An AND operator accepts two inputs and produces a single output.

If both the inputs are CLOSE, then the output is ON. Otherwise, the output is OFF.

In Boolean expression, the AND operation is expressed using the “.” dot operator or “” asterisk operator.

X=A ⋅ B or X=A B

where A and B are the inputs and X is the output.

Truth table for AND operator:

INPUTA
INPUT

B

OUTPUT

X
OPEN OPEN OFF
OPEN CLOSE OFF
CLOSE OPEN OFF
CLOSE CLOSE ON

OR Operator:

An OR operator accepts two inputs and produces a single output.

If both the inputs are OPEN, then the output is OFF. Otherwise, the output is ON.

In Boolean expression, the OR operation is expressed using the “+” plus sign.
X=A+B

where A and B are the inputs and X is the output.

Truth table for OR operator:

INPUTA
INPUT

B

OUTPUT

X
OPEN OPEN OFF
OPEN CLOSE ON
CLOSE OPEN ON
CLOSE CLOSE ON

Programming Problems 9.28 Assume that a system has a 32-bit virtual address with a 4-KB page size. Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1. Request for a contiguous block of memory 2. Release of a contiguous block of memory 3. Compact unused holes of memory into one single block 4.…
