Explanation:

Scenarios are quite common where an IT professional is tasked with modify a file on many computer systems or many files on a single computer or a combination of the two. For example, a large software may need the copyright notice comment to be changed on every source file in the project. Or, a configuration file may need to be modified on every server in a multi-server deployment. Doing this task manually is not a viable way to approach the problem. Instead, a better solution is to use a scriptable environment to perform search and replace functionality on the files in question. Python is an excellent tool for this kind of task.
Description
Samba is a unix/linux file sharing suite of programs designed to provide Windows interoperable file and print sharing services. Much of the configuration for the Samba daemon is provided by the text file smb.conf (renamed to smb.txt for this assignment). After an update was deployed to three dozen linux servers it was discovered that a couple of configured parameters were incorrect. Unfortunately, since there are unique aspects to each server, copying the contents of a single file to each server is not a viable solution. To fix the problem, the IT department must connect to each server, edit the smb.conf file, and restart the smbd daemon. To automate this task, each server will have a Python script copied to it. Then an SSH session will be initiated to each server from which the script will be executed. Your task is to write the Python script.
The invocation of the script must be as follows:
python modify.py fileSpec "from" "to"
where,
modify.py is the name of your script
fileSpec is the name of the file to be modified (smb.txt)
"from" is the text to be searched for (be sure to enclose any white space in quotes.
"to" is the text the searched text is to be replaced with.
Testing the script is your responsibility. However a good test case is:
python modify.py smb.txt "password sync = yes" "password sync = no"

Explanation:/

The example Python script that can be used to automate the modification of the smb.conf file on multiple Linux servers is shown below

What is the code?

python

import subprocess

import sys

def modify_smb_conf(file_spec, search_text, replace_text):

try:

# Open the file for reading

with open(file_spec, 'r') as file:

# Read the contents of the file

file_contents = file.read()

# Perform the search and replace operation

modified_contents = file_contents.replace(search_text, replace_text)

# Open the file for writing

with open(file_spec, 'w') as file:

# Write the modified contents back to the file

file.write(modified_contents)

# Print a success message

print(f"Modification successful: Replaced '{search_text}' with '{replace_text}' in {file_spec}")

except IOError as e:

# Print an error message if there was an issue with file operations

print(f"Error: {e}")

def main():

# Check if the correct number of command line arguments are provided

if len(sys.argv) != 4:

print("Usage: python modify.py fileSpec \"from\" \"to\"")

return

# Extract the command line arguments

file_spec = sys.argv[1]

search_text = sys.argv[2]

replace_text = sys.argv[3]

# Call the function to modify the smb.conf file

modify_smb_conf(file_spec, search_text, replace_text)

if __name__ == '__main__':

main()

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int count = 0;

int highest, lowest;

ArrayList<Integer> myArr = new ArrayList<>();

while (true) {

System.out.println("Enter a number [0-10] or -1 to exit");

int num = in.nextInt();

if (num != -1) {

if ((num >= 0) && (num <= 10)) {

count+= 1;

myArr.add(num);

} else {

System.out.println("Wrong Value");

}

} else {

break;

}

if (myArr.size() > 3) {

highest = myArr.get(0);

lowest = myArr.get(0);

for (int x: myArr) {

if (x > highest) {

highest = x;

}

if (x < lowest) {

lowest = x;

}

System.out.println("Number of Elements: " + count);

System.out.println("Highest: " + highest);

System.out.println("Lowest : " + lowest);

} else {

System.out.println("Number of Elements: " + count);

System.out.println("No Highest or Lowest Elements");

}

What is indirect program memory addressing? Explain the working of the following instructions?

a) JMP AX
b) JMP LIST[DX]
c) JMP NEAR PTR[DI+3]

Answers

Indirect main memory addressing is described as the method in which the variable's address is stored in a mind register and also a command is utilized to point towards the memory registers which hold the register. Instruction is used to direct towards a register that displays the results of the variables. The register, in turn, refers to that variable's address in simplistic words. As just a result, it is indeed considered a passive program, memory address.

The instructions operate as follows:

JMP AX :

The JMP instruction is being used to execute an unconditional jump.AX is indeed the label's name. JMP AX codes are being used to transfer control of the flow program to the AX label.

JMP LIST:

The JMP command can be used to execute an unconditional jump, JMP LIST[DX] is the label's name. The JMP LIST[DX] program is being used to transfer control of its flow programs to the specified section. It is the segment to which the flow control is transmitted.

JMP NEAR PTR[DI+3]:

Unconditional jumps could be done with the JMP command as you'll see, the label is JMP NEAR PTR[DI+3]. It's being used to transmit flow control to a particular section, throughout this case [DI+3]. The close keyword indicates that perhaps the code segment would be in the line of code being nearby.

What is an Analog computer?

An analog computer may be defined as a type of computer that is significantly used to process analog data. These computers store data as a continuum of physical quantities and perform calculations using measurements.

It is completely different from digital computers, which use symbolic numbers to represent results. are great for situations that require data to be measured directly without conversion to numbers or codes. Analog computers, although readily available and used in scientific and industrial applications such as control systems and aircraft, have largely been superseded by digital computers due to the many complications involved.

Therefore, the analog computer deals directly with measured values of continuous physical magnitude.
