Question
Chapter 3, Problem 1LO
Program Plan Intro
The description of the members of hierarchy of data.
Expert Solution & Answer
Explanation of Solution
The
Bit is the smallest member in the data hierarchy. Bits represent the values of a circuit as either on or off. A combination of 8-bits called byte is used to represent any character in a computer system.
Character is the next member of the data hierarchy. Each byte represents a character. Character can have any values ranging from A to Z, a to z, 0 to 9 or any special character. Character forms the basic building block for information.
Field is formed when multiple characters are put together. Fields can have any name, number, address or any combination of character. Some fields are evaluated out of other fields like sum, average and so on.
Record is the next member of the data hierarchy. A collection of related data fields forms a record. So, in a record, there will be description of an individual or object.
File is formed with the collection of the record related to each other. For example, an employee file will contain the record of employees. In the record, there will be the fields like Name, Address, and Employee id and so on.
Database is the last member of the data hierarchy. Database consists of related files.

: 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…

Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel.
