Answer:

a. The DVD drive SATA connector is disabled.

b. The DVD drive cable is loose or disconnected.                                                                                  

Explanation:          

When using an M.2 SSD card in M.2 slot on the motherboard, SATA ports are disabled. This is because sometimes these ports break out of their connection or link. So check SATA connectors and check if the SATA cables are connected to the SATA port properly. Also sometimes that DVD drive does not show up when you boot your system after installing m.2 SSD card because of the loose or disconnected cable. This cable can be unknowingly unplugged so all the cable connections must be checked in order to resolve this issue.

Pick the 3 correct Python functions that parse and output only the date and time part of each log in log.txt as follows.
Mila [183]

Answer:

1, 4, 5

Explanation:

parse2:

. In this case it's passing "r" as an argument, which really does absolutely nothing, because whenever you call open("file.txt") it defaults to reading mode, so all you're doing is explicitly passing the "r". So let's look at the first line. Whenever you call str.split() without any arguments, by default it splits it by empty text, and filters any empty text. So str.split() is not the same as str.split(" ") although it has similar behavior. "     ".split(" ") will output ['', '', '', '', '', ''], while "     ".split() will output []. So in this case the line.split() will split the string '10.1.2.1 - car [01/Mar/2022:13:05:05  +0900] "GET /python HTTP/1.0" 200 2222' into the list<em> ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222'].</em> As you can see the the data is split into two pieces of text, AND they include the brackets in both strings. So when it gets the 3 index and strips it of the "[]" it will have the incomplete date

parse3:

 In this instance the "r" does nothing as mentioned before the "r" is already defaulted whenever you call open("file.txt") so open("file.txt") is the same as open("file.txt", "r"). So in this case we won't be working left to right, we're going inside the brackets first, kind of like in math you don't don't work left to right in equation 3 + 3(2+3). You work in the brackets first (inside brackets you do left to right). So the first piece of code to run is the line.split("[" or "]"). I actually kind of misspoke here. Technically the "[" or "]" runs first because this doesn't do what you may think it does. The or will only return one value. this is not splitting the line by both "[" and "]". The, or will evaluate which is true from left to right, and if it is true, it returns that. Since strings are evaluated on their length to determine if they're true. the "[" will evaluate to true, because any string that is not empty is true, if a string is empty it's false. So the "[" will evaluate to true this the "[" or "]" will evaluate to "[". So after that the code will run line.split("[") which makes the list: <em>['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900] "GET /python HTTP/1.0" 200 2222']</em>. Now the [3:5] will splice the list so that it returns a list with the elements at index 3 (including 3) to 5 (excluding 5). This returns the list: [], because the previous list only has 2 elements. There are no elements at index 3 to 5 (excluding 5). So when you join the list by " ", you'll get an empty string

parse4:

  So I'm actually a bit confused here, I thought the "r+" would open the file in read-writing mode, but maybe this is a different version of python I have no idea, so I'm going to assume it is reading/writing mode, which just means you can read and write to the file. Anyways when you split the line by doing line.split(), as mentioned before it will split by empty spaces and filter any empty spaces. This line will return: <em>['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']</em>. and then you splice the list from indexes 3 to 5 (excluding 5). This will return the list: <em>['[01/Mar/2022:13:05:05', '+0900]']</em> which has the two pieces of information you need for the date. Now it joins them by a space which will output: '[01/Mar/2022:13:05:05 +0900]'. Now when you strip the "[]" you get the string: '01/Mar/2022:13:05:05 +0900' which is the correct output!

parse 5:

 So in this example it's using re.split. And the re.split is splitting by "[" or "]" which is what re.split can be used for, to split by multiple strings, which may be confused by string.split("[" or "]") which is not the same thing as explained above what the latter does. Also the reason there is a backslash in front of the [ and ] is to escape it, because normally those two characters would be used to define a set, but by using a \ in front of it, you're essentially telling regex to interpret it literally. So in splitting the string by "[" and "]" you'll get the list: <em>['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900', ' "GET /python HTTP/1.0" 200 2222']</em> which has 3 elements, since it was split by the [ and the ]. The second element has the date, so all you need to do is index the list using the index 1, which is exactly what the code does

A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out
dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

 int userNum;

 Scanner input = new Scanner(System.in);

 System.out.print("Enter integer: ");

 userNum = input.nextInt();

 System.out.println("You entered "+userNum);

 System.out.println(userNum+" squared is "+(userNum*userNum));

 System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

 int userNum2;

 System.out.print("Enter another integer: ");

 userNum2 = input.nextInt();

 int sum= userNum + userNum2; int product = userNum2 * userNum;

 System.out.println(userNum+" + "+userNum2+" = "+sum);

 System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

 int userNum;

 Scanner input = new Scanner(System.in);

This prompts the user for input

 System.out.print("Enter integer: ");

This gets user input from the user

 userNum = input.nextInt();

Number (1) is implemented here

 System.out.println("You entered "+userNum);

Number (2) is implemented here

 System.out.println(userNum+" squared is "+(userNum*userNum));

 System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

 int userNum2;

This prompts the user for another input

 System.out.print("Enter another integer: ");

This gets user input from the user

 userNum2 = input.nextInt();

This calculates the sum and the product

 int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

 System.out.println(userNum+" + "+userNum2+" = "+sum);

 System.out.println(userNum+" * "+userNum2+" = "+product);

Write a function called getChar that has no function inputs, but takes in two character inputs from the user (in1 and in2) and o
bearhunter [10]

Answer:

def getChar():

   while True:

       in1 = input('Enter first char: ')

       try:

           if len(in1) != 1:

               raise

           else:

               in2 = input('Enter second char: ')

               if len(in2) != 1:

                   raise

               else:

                   break

       except:

           print('Enter just one character')

   return in1, in2

def chars2string(in1,in2):

   print(in1*5 + in2*5)

def main():

   ls = getChar()

   in1 = ls[0]

   in2 = ls[1]

   chars2string(in1, in2)

if __name__ == '__main__':

   main()

Explanation:

The programming language used is python 3.

The script first defines a function getChar and makes use of a while loop in combination with try and except blocks and IF statements, the code ensures that both inputs that are entered by the user after the prompt are 1 in length. i.e. Just one character. This function returns the two characters that were entered.

The second function that is defined is chars2string this function takes two arguments, It repeats each argument five times and returns a joined string.

Finally, the main function is defined and it calls the getChar function  first, the values that are returned by this function is assigned to two variables, that is then passed on to the chars2string function. The main function is called and the Joined string is printed to the screen.

What should you do if a headset plugged into your computer is not working properly?
Alex777 [14]

If a headset plugged into computer is not working properly than one can go for updating the device driver. The correct option is B.

<h3>What is a device driver?</h3>

A device driver is a type of software application that allows one hardware device (such as a computer) to communicate with another hardware device (such as a printer). A device driver is indeed referred to as a software driver.

A driver, also known as a device driver, is a collection of files that instructs a piece of hardware on how to operate by communicating with a computer's operating system.

Every piece of hardware, from internal computer components like your graphics card to external peripherals like a printer, requires a driver.

If a headset plugged into a computer is not working properly, the device driver can be updated.

Thus, the correct option is B.
