Chapter 6, Problem 33E
Explanation of Solution
Consider the given instructions:
0001 D0 00 48
0004 F1 FC 16
Executing the first instruction:
Consider the first instruction “D0 00 48” stored in the address “0001”.
- Here, the hexadecimal value “D0” is an instruction and “00 48” is the operand.
- The binary equivalent of the instruction “D0” is “1101 0000”, which will be stored in the instruction specifier.
- In the instruction specifier, the first four bits refers the operation code, the fifth bit refers the register specifier, and the next three bits refers the addressing mode.
- The first four bits “1101” – Load byte into the “A” register.
- The fifth bit “0” – Indicates the “A” register (Accumulator).
- The next three bits “000” – Immediate addressing mode.
- The binary equivalent of the operand “00 48” is “0000 0000 0100 1000”, which will be stored in the operand specifier.
- Since the addressing mode is immediate, the first byte of the operand specifier is ignored and the second byte value will be stored into the accumulator.
- So, the second byte value “0100 1000” will be stored into the accumulator.
Thus, after the execution of the first instruction, the “A” register will contain the value “0100 1000”...

In recent years, growing demand has exposed the limitations of their fragmented processes and outdated systems.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. Differentiate between continuous and discrete systems.

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_forward3.) 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_forward

Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer.

Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'. Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function. Additionally, you are provided with five useful gadgets and their addresses. Use these gadgets to construct the stack layout.
