If ax +b * c / g is input from the Keyboard ; trace the path of execution from theKeyboard to the final output onto the printer which uses bidirectional I/O interface,using all your knowledge in computer architecture design

Input Phase: The user inputs the expression "ax +b * c / g" from the keyboard. This is done by pressing the keys corresponding to the characters in the expression. Each key press sends a signal to the keyboard's controller, which translates the signal into a binary code known as a scan code. This scan code is then sent to the computer's processor.

Processing Phase: The processor receives the scan code from the keyboard and sends it to the operating system. The operating system interprets the scan code and converts it into the corresponding characters of the expression. This expression is then passed to the application or program that is currently active and waiting for user input. In this case, it would be a program that can interpret and calculate mathematical expressions.

Calculation Phase: The program receives the expression and parses it to understand the operations that need to be performed. It identifies the variables (a, b, c, g, x), the operations (+, *, /) and the order in which they need to be performed (according to the BODMAS rule). It then performs the calculations.

Output Phase: Once the calculations are done, the result is sent back to the operating system. The operating system then sends this result to the printer driver.

Printing Phase: The printer driver receives the result and converts it into a format that the printer can understand. It then sends this formatted result to the printer via the bidirectional I/O interface. The printer receives the result and prints it out. The bidirectional I/O interface allows the printer to send feedback back to the computer, such as status information or error messages.

Final Output: The final output is the printed result of the expression "ax +b * c / g".
