Answer:

The correct answer to the following question will be Option C (cp filename.txt destination).

Explanation:

The command cp is a control-line tool for folder and directory copying. This allows transferring one or more documents or folders with tools for backup-taking and attributes protection.

The general syntax of using the cp command is:

cp SOURCE file DESTINATION file

For example:

cp firstname.txt destination

here, firstname.txt is source file name and destination is the destination file name.

Option A, option D doesn't follow the general syntax of cp command that's why these options are incorrect, therefore, option C is the right answer.

# User is prompted to enter the number of floor in hotel

# The received value is assigned to no_of_floor

no_of_floor = int(input("Enter the number of floor in the hotel."))

# This loop is to enforce that user input is not less than 1

while (no_of_floor < 1):

   no_of_floor = int(input("Enter the number of floor in the hotel."))

# counter variable is initialized to loop through the no_of_floor

counter = 1

# total number of rooms occupied in the hotel is initialized to 0

total_occupied = 0

# total number of rooms vacant in the hotel is initialized to 0

total_vacant = 0

# total number of rooms in the hotel is initialized to 0

total_room = 0

# loop through each floor

while counter <= no_of_floor:

   # number of room in a floor is received from user

   number_of_room = int(input("Enter the number of room in floor: "))

   # this loop ensure that the number must not be less than 10

   while (number_of_room < 10):

       number_of_room = int(input("Enter the number of room in floor "))

   # number of occupied room is a floor is accepted from user

   number_of_occupied = int(input("Enter the number of occupied room."))

   # this loop ensure that the no_of_occupied is less than no_of_room

   while (number_of_occupied > number_of_room):    

       number_of_occupied = int(input("Enter the number of occupied room."))

   # number of vacant room in a floor is calculated

   floor_vacant = number_of_room - number_of_occupied

   # total number of occupied room is calculated

   total_occupied += number_of_occupied

   # total room in the hotel is calculated

   total_room += number_of_room

   # total number of vacant room is calculated

   total_vacant += floor_vacant

   # the counter is increment to move to the next floor

Answer:

The cursor changes to a two edged arrow pointer and the bounding box is highlighted.

Explanation:

Bounding boxes in windows operating system is a boundary line of the windows box that run that runs applications and other utilities in the system. A sizing handle is a tool used in place of a the minimize and maximize button on top of the windows box. It is found on the bottom right edge of the windows box.

When a cursor points to the sizing handle, the cursor changes to a double edge arrow pointer and the bounding box is highlighted, and can be resized on the screen.

Answer:

The correct answer is: the cursor changes to a two edged arrow pointer.

Explanation:

Sizing handles allow users to resize objects -typically windows- at will by placing the cursor over one of the corners of the object. A double edge arrow will replace the cursor. The user will have to left-click the mouse and drag the sizing handle to modify the size of the object. After letting the left click go and moving the mouse around, the cursor appears again with its regular features.

Final answer:

Hackers exploit vulnerabilities using tactics like phishing, malware, and social engineering to steal sensitive data. The stolen data is used for financial gain or identity theft. Reducing hacking requires updates, security measures, and user education.

Explanation:

When evaluating the techniques that hackers use to compromise systems, one common method is by exploiting various vulnerabilities. Hackers might target vulnerabilities within software, such as outdated systems, unpatched flaws, or configuration errors.

They deploy tactics such as phishing, malware, and social engineering to trick users into giving up sensitive information or to gain unauthorized access to systems.

Among the reasons hackers engage in these activities are to steal personal data, financial information, or intellectual property. The stolen data can be used for financial gain, identity theft, or even to gain a competitive advantage.

Hackers are often quite successful due to the sophistication of their tactics and the general lack of awareness and preparedness among users. To reduce or stop hacking, it is essential to consistently update systems, implement security measures like firewalls and antiviruses, and educate users on best practices for cyber hygiene.

Answer:

i looked it up and the answer i got would be D

Explanation: hope this helps!

Explanation:

Reason:

Answer:

(a) 845 = 0000 0011 0100 1101

(b) 1500 = 0011 1010 1001 1000

(c) 100 = 0000 0000 0110 0100

(d) -923 = 1111 1100 0110 0101

Explanation:

NOTES:

First Note: The question requests that the numbers be represented in word-length. That means they should be represented in 16bits (a word is 2 bytes).

Second Note: To convert a number to its 2's complement representation,

(i) if the number is positive, the usual conversion to binary will suffice. You might just need to add zero at the beginning of the sequence of bits to ensure that the leftmost bit is a zero(0).

(ii) if the number is negative, then;

=> convert the magnitude of the number to its binary

=> add zeros to the beginning of the sequence of binary until the sequence has the specified length

=> flip each bit in the sequence and add 1 to the result.

SOLUTION:

Applying the rules in the notes above, lets convert the numbers.

(a) 845 => The number is positive, conversion to its binary will suffice

2  |  845

2  |  422 R 1

2  |  211 R 0

2  |  105 R 1

2  |  52 R 1

2  |  26 R 0

2  |  13 R 0

2  |  6 R 1

2  |  3 R 0

2  |  1 R 1

2  |  0 R 1

Writing the remainders upwards, we have

845 = 1101001101

Pad with zeros to convert it to its word-length representation.

845 = 0000 0011 0100 1101

(b) 15000 => The number is also positive, so following the same step as above,

15000 = 11101010011000

Pad with zeros to convert it to its word-length representation.

15000 = 0011 1010 1001 1000

(c) 100 => The number is also positive, so following the same step as above,

100 = 1100100

Pad with zeros to convert it to its word-length representation.

100 =  0000 0000 0110 0100

(d) -923 => The number is negative;

-->  first convert its magnitude (923) to binary

923 = 1110011011

--> Pad with zeros to convert it to its word-length representation.

923 =  0000 0011 1001 1011

--> Flip the bits

0000 0011 1001 1011 = 1111 1100 0110 0100

--> Add 1 to the result above

1111 1100 0110 0100 + 1 = 1111 1100 0110 0101

Therefore;

-923 = 1111 1100 0110 0101

The word length 2's complement representations are:

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100

d. -923: 1111110001000101

We have,

To find the word-length 2's complement representation of each decimal number, we first need to determine the binary representation of the absolute value of the number and then convert it into its 2's complement form if the number is negative.

Assuming the word length is 16 bits:

a. 845:

Binary representation of 845: 0011 0100 1101

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 0100 1101

b. 15000:

Binary representation of 15000: 0011 1011 0110 0000

Since it is positive, the 16-bit 2's complement representation remains the same: 0011 1011 0110 0000

c. 100:

Binary representation of 100: 0000 0000 0110 0100

Since it is positive, the 16-bit 2's complement representation remains the same: 0000 0000 0110 0100

d. -923:

Binary representation of 923: 0000 0011 1011 1011

To find the 16-bit 2's complement representation, we first invert all the bits: 1111 1100 0100 0100

Then, add 1 to the inverted value: 1111 1100 0100 0101

So, the 16-bit 2's complement representation of -923 is: 1111 1100 0100 0101

Thus,

a. 845: 001101001101

b. 15000: 0011101101100000

c. 100: 0000000001100100

d. -923: 1111110001000101
