Chapter 4, Problem 4P
Explanation of Solution
a.
Data stored in the destination address of AND operation:
- In AND operation, the output is always HIGH when all the inputs are HIGH and the output is LOW when any of the inputs are LOW.
- The AND operation of two inputs “Source A” and “Source B” is given below. Here, the result is stored in destination address.
- If both the inputs “Source A” and “Source B” are 1, then the output 1 will be displayed on the destination.
- Otherwise, if either of the inputs “Source A” or “Source B” is 0, then the output 0 will be displayed on the destination.
Source A:
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 0 | 1 | 0 |
Explanation of Solution
b.
Data stored in the destination address of OR operation:
- In OR operation, the output is always HIGH when any of the inputs are HIGH and the output is LOW when all the inputs are LOW.
- The OR operation of two inputs Source A and Source B is given below. Here, the result is stored in destination address.
- If either of the inputs “Source A” or “Source B” are 1, then the output 1 will be displayed on the destination.
- Otherwise, if both the inputs “Source A” and “Source B” are 0, then the output 0 will be displayed on the destination.
Source A:
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 0 | 1 | 0 |
Explanation of Solution
c.
Data stored in the destination address of XOR operation:
- In Exclusive-OR (XOR) operation, the output is always HIGH when either of the inputs is HIGH and the output is LOW when all the inputs are either HIGH or LOW.
- The XOR operation of two inputs Source A and Source B is given below. Here, the result is stored in destination address.
- If either of the inputs “Source A” or “Source B” are 1, then the output 1 will be displayed on the destination.
- Otherwise, if both the inputs “Source A” and “Source B” are 0 or 1, then the output 0 will be displayed on the destination.
Source A:
| 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 0 | 1 | 0 |

In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems. Different departments manage production schedules, raw material requirements, and finished goods inventory using a patchwork of spreadsheets and older software tools. These silos create inconsistent data, errors in stock levels, delivery delays, and customer dissatisfaction. Green Fields plans to implement an Integrated Inventory Management System to centralise production, procurement, inventory, and sales data to address these challenges. This technology aims to provide real-time visibility into stock levels, automate reorder points, and generate analytical dashboards for managers at both operational and strategic levels. Ultimately, the new system will streamline workflows, reduce…arrow_forward

Word FrequencyWrite a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward
- 3.) File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.arrow_forwardReturns an US standard formatted phone number, in the format of (xxx) xxx-xxxx the AreaCode, Prefix and number being each part in order.
