Explanation:

Our technological world has become deeply dependent upon the continuous availability of electrical power. In most countries, commercial power is made available via nationwide grids, interconnecting numerous generating stations to the loads. The grid must supply basic national needs of residential, lighting, heating, refrigeration, air conditioning, and transportation as well as critical supply to governmental, industrial, financial, commercial, medical and communications communities. Commercial power literally enables today’s modern world to function at its busy pace. Sophisticated technology has reached deeply into our homes and careers, and with the advent of e-commerce is continually changing the way we interact with the rest of the world. Intelligent technology demands power that is free of interruption or disturbance. The consequences of large-scale power incidents are well documented. A recent study in the USA has shown that industrial and digital business firms are losing $45.7 billion per year due to power interruptions.1 Across all business sectors, an estimated $104 billion to $164 billion is lost due to interruptions with another $15 billion to $24 billion due to all other power quality problems. In industrial automatic processing, whole production lines can go out of control, creating hazardous situations for onsite personnel and expensive material waste. Loss of processing in a large financial corporation can cost thousands of unrecoverable dollars per minute of downtime, as well as many hours of recovery time to follow. Program and data corruption caused by a power interruption can create problems for software recovery operations that may take weeks to resolve. Many power problems originate in the commercial power grid, which, with its thousands of miles of transmission lines, is subject to weather conditions such as hurricanes, lightning storms, snow, ice, and flooding along with equipment failure, traffic accidents and major switching operations. Also, power problems affecting today’s technological equipment are often generated locally within a facility from any number of situations, such as local construction, heavy startup loads, faulty distribution components, and even typical background electrical noise

Answer:

-11001

Explanation:

The following steps are performed in order to perform subtraction of the given binary numbers:

Step 1:

Find 2’s complement of the subtrahend. The subtrahend here is 100000

100000

First take 1's complement of 100000

1's complement is taken by inverting 100000

1's complement of 100000 = 011111

Now takes 2's complement by adding 1 to the result of 1's complement:

011111 + 1 = 100000

2's complement of 100000 = 100000

Step 2:

Add the 2's complement of the subtrahend to the minuend.

The number of bits in the minuend is less than that of subtrahend. Make the number of bits in the minuend equal to that of subtrahend by placing 0s in before minuend. So the minuend 111 becomes:

000111

Now add the 2's complement of 100000 to 000111

   0 0 0 1  1  1

+   1 0 0 0 0 0

    1 0 0 1  1  1

The result of the addition is :

 1 0 0 1  1  1

Step 3:

Since there is no carry over the next step is to take 2's complement of the sum and place negative sign with the result as the result is negative.

sum =   1 0 0 1  1  1

2's complement of sum:

First take 1's complement of 1 0 0 1  1  1

1's complement is taken by inverting 1 0 0 1  1  1

1's complement of 1 0 0 1  1  1 = 0 1 1 0 0 0

Now takes 2's complement by adding 1 to the result of 1's complement:

0 1 1 0 0 0 + 1 = 0 1 1 0 0 1

Now place the minus sign with the result of 2's complement:

- 0 1 1 0 0 1

Hence the subtraction of two binary numbers (100000)₂ and (111)₂  is

(-011001)₂

This can also be written as:

(-11001)₂

A breach of security can be defined as any incident which results in an unauthorized access or privileges to a network, computer, software application, classified informations or data and services. There are three (3) levels of impact on an individual or organization when there's a breach of security; low, moderate and high.

A moderate level breach of security could cause a significant degradation in mission capability to an extent and duration that the organization is able to perform its primary functions, but the effectiveness of the functions is significantly reduced. It causes a serious adverse effect on individuals, employees or organizational assets and operations.

However, in order to prevent a breach of security, it is advisable to use the following programs: firewall, demilitarized zone (DMZ), Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) etc.

Answer: Print spooler is most common example of Print Quality

<marquee>mark me as the brainliest

Print spooler is most common example of: Buffer.

In Computer technologies, an output device can be defined as a hardware device that is designed to typically receive processed data from the central processing unit (CPU) and converts these data into an information that can be used by the end users of a computer system. Some examples of an output device are speaker, monitor, projector, printer, etc.

A printer can be defined as an electronic output device (peripheral) that is designed and developed for printing of paper documents containing texts and images.

Generally, a printer comprises the following components and software resources; paper support, print cover, connectors, output tray, edge guides, sheet feeder, control buttons, ink cartridge clamps, print head, print drivers, print spooler, etc.

A print spooler can be defined as a software application or program installed on a printer to organize, manage and control the paper printing jobs that are being sent to a printer by a computer. Thus, the execution and operation of various print jobs by a printer in printing documents is highly dependent on its print spooler.

A buffer can be defined as a temporary storage area set aside on a computer for data storage. Also, a buffer resides in the random access memory of a computer system.

This ultimately implies that, a print spooler is most common example of a buffer because it stores data, instructions and processes related to print jobs from multiple sources in a queue to sequentially execute them later on.

Explanation:

This line initialized the input prices using a string variable named prices

prices = "34.62 76.30 85.05"

This line converts prices to list

stock_prices = prices.split()

The following iteration prints each element of the list

Options :

A.) s1 < s2

B.) s1 <= s2

C.) s1.compareTo(s2) == −1

D.) s2.compareTo(s1) < 0

E.) s1.compareTo(s2) < 0

Answer: E.) s1.compareTo(s2) < 0

Explanation: Lexicographical ordering simply means the arrangement of strings based on the how the alphabets or letters of the strings appear. It could also be explained as the dictionary ordering principle of words based on the arrangement of the alphabets. In making lexicographical comparison between strings, the compareTo () method may be employed using the format below.

If first string = s1 ; second string = s2

To compare s1 with s2, the format is ;

s1.compareTo(s2) ;

If s1 comes first, that is, before s2, the method returns a negative value, that is a value less than 0 '< 0', which is the case in the question above.

If s2 comes first, that is, before s1, the method returns a positive value, that is a value greater than 0 '> 0'.

If both are s1 and s2 are the same, the output will be 0.

Answer:

Here is the expression:

user_grade = 10 #assigns 10 to the value of user_grade

if user_grade >=9 and user_grade <=12:  #checks if the user_grade is between 9 and 12 inclusive

   print('in high school')  # prints in high school if above condition is true

else:  #if user_grade is not between 9 and 12 inclusive

   print('not in high school') # prints not in high school if user_grade is not between 9 and 12 inclusive

This can also be written as:

user_grade = 10  # assigns 10 to user_grade

if 9<=user_grade<=12:  #if statement checks if user_grade is between 9 and 12 inclusive

   print('in high school')  #displays this message when above if condition is true

else:  #when above if condition evaluates to false

   print('not in high school')#displays this message

Explanation:

If you want to take the user_grade from user as input then:

user_grade = int(input("Enter user grade: "))

if user_grade >=9 and user_grade <=12:

   print('in high school')

else:

   print('not in high school')

The expression

if user_grade >=9 and user_grade <=12:  

contains an if statement that checks a condition that can either evaluate to true or false. So the if condition above checks if the value of user_grade is between 9 and 12 inclusive.

Here the relational operator >= is used to determine that user_grade is greater than or equals to 9. relational operator <= is used to determine that user_grade is less than or equals to 12.

The logical operator and is used so both user_grade >=9 and user_grade <=12 should hold true for the if condition to evaluate to true. This means the user_grade should be between 9 and 12 (inclusive).

For example is user_grade = 10 then this condition evaluates to true as 10 is between 9 and 12 (inclusive). Hence the message: in high school is displayed on output screen.

But if user_grade= 13 then this condition evaluates to false because 13 is greater than 12. Hence the message: not in high school is displayed on output screen.

If user_grade = 8 then this condition evaluates to false because 8 is less than 9. Notice here that 8 is less than 12 so one part of the condition is true i.e. user_grade <=12 but we are using logical operator and so both the parts/expressions of the if condition should evaluate to true. This is why this condition evaluates to false. Hence the message: not in high school is displayed on output screen.

The answer is "Option B".

Explanation:

The 3-dimensional diagrams also known as a 3D graph, it implies to 3D design, which Occasionally receives the 2D data, which effects 3D and It is a terrible form.

Answer:

Here is the C++ program:

#include <iostream> //to use input output functions

#include<string.h> // to manipulate strings

using namespace std; //to identify objects like cin cout

void ReverseString(char* original_str){ // function that reverses a C-string

       char* ptr1 = original_str;  // pointer that points to the start of C-string

       char* ptr2 = original_str; // pointer that points to the start of C-string initially

       for (int i = 0; i < strlen(original_str)- 1; i++) {//iterates through the length of the C-string

           ptr2++;} //moves ptr2 to the end of the C-string

       while(ptr1 < ptr2) {// swaps each character of C-string using pointers

               char temp = *ptr1; //declares a temp variable to hold character that *ptr1 points to

               *ptr1 = *ptr2;

               *ptr2 = temp;

               ptr1++; //increments ptr1 moving it forward

               ptr2--;   }} //decrements ptr2 moving it backwards

int main(){ //start of main() function

       char input_str[]="";  /// declare a C-string

       cout<<"Enter original string: "; //prompts user to enter a string

       cin>>input_str; // reads that C-string from user

       ReverseString(input_str); //calls function to revserse the input string

       cout<<"\nReversed string: "<<input_str;} // displays the reversed string

Explanation:

The program has a function ReverseString that takes a C-style string as parameter and reverses the string using pointers.

The ptr1 and ptr2 are pointers that initially point to the beginning of original string.

for (int i = 0; i < strlen(original_str)- 1; i++) this statement has a for loop that iterates through the original string and moves the ptr2 to point at the end or last character of the C-string. strlen() method is used to get the length of the C-string. At each iteration ptr2 moves one time forward until the last character of the C-string is reached.

while(ptr1 < ptr2) statement has a while loop that works as follows:

checks if ptr1 is less than ptr2. This evaluate to true because the index of first character that ptr1 points to is 0 and last character is 5 so 0<5. Hence the statements inside while loop execute which swaps the character of C-string from beginning and end index using ptr1 and ptr2. a temp variable is declated to hold character that *ptr1 points to.

For example

original_string = "xyz" Then temp = *ptr1; stores the character that *ptr1 points to i.e. 'x'

*ptr1 = *ptr2; This statement assigns the character that *ptr2 points to the *ptr1. Basically these pointers are used as indices to the C-string. So this means that the *ptr1 now stores the last character of the C-string that is pointed to by *ptr2. So *ptr1 = 'z'

*ptr2 = temp; This statement assigns the character that temp stores to the *ptr2. We know that temp contains the first character i.e 'x'. So *ptr2 = 'x'      

ptr1++; The ptr1 is incremented to 1. This means it moves one position ahead and now points to the second character of the C-string.

ptr2--; The ptr2 is decremented to 1. This means it moves one position backwards and now points to the second character of the C-string.

Now the while loop breaks because ptr1 < ptr2 condition evaluates to false.

So the original string is reversed using pointers. Hence the output is:

Answer:

a) [00:05:00]

Explanation:

Timestamps are markers in a transcript which are used to represent when an event took place. Timestamps are in the format [HH:MM:SS] where HH is used to represent hour, MM to represent the minute and SS to represent the seconds. They are different types of timestamping such as:

i) Periodic time stamps: Occurs at a consistent frequency

ii) Paragraph time stamping: At the beginning of paragraphs

iii) Sentence time stamp: at the beginning of sentence

iv) Speaker time stamp: at change of speaker.

Since a part of 5-15 minutes with time-stamping (every 30 seconds), The time stamping should start at 5 minute [00:05:00] and end at [00:15:00]. This is a periodic time stamp since it occurs every 30 seconds, this means the next time stamp would be [00:05:30] and this continues until 15 minute [00:15:00]

Based on the information given, the time stamping will be A. [00:05:00]

It should be noted that timestamps simply mean the markers that we in a transcript that are used to represent when an event took place.

They are typically in the format [HH:MM:SS]. Therefore, if you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at 00:05:00.

(c) A list of words

Explanation:

First let's format the code properly

fin = open('words.txt')

for line in fin:

     word = line.strip()

     print(word)

Second, let's explain each line of the code

Line 1:

The open() function is a built-in function that takes in, as argument, the name of a file, and returns a file object that can be used to read the file.

In this case, the name of the file is words.txt. Therefore, the variable fin is a file object which contains the content of the file - words.txt

Line 2:

The for loop is used to read in each line of the content of the file object (fin).

Line 3:

Each line of the contents is stripped to remove any trailing and leading white spaces by calling on the strip() function. The result of the strip is stored in the variable word.

Line 4:

The content of word at each of the cycles of the loop is printed to the console.

Therefore,  the overall output of the program is a list of words where each word represents a line in the target file (words.txt)

The program is an illustration of string manipulations.

word represents (e) A string with no newline

The program is given as:

fin = open('words.txt')

for line in fin:

        word = line.strip()

        print(word)

On line 3 of the program, the variable word contains the value of the string line, after the new lines and trailing spaces have been removed from the variable line.

This means that: variable word is a string with no newline
