Explanation:

This line initializes all letter grade from A to F

letterg = ['A','B','C','D','F']

This line prompts user for letter grade

inp = input("Enter a Letter Grade: ")

This line iterates through the initialized letter grades

for i in range(len(letterg)):

This line checks if the user input is present in the initialized letter grades (it also takes care of lowercase letters)

if inp.upper() == letterg[i]:

This line is executed if tge about condition is true; the line calculates the number grade and prints it

print('The numeric value for grade ', inp, ' is ',4 - i)

This line terminates the iteration

break;

If the condition above is not true

Answer:

xyz = 25  

result = square(xyz)

print(result)

The above code assigns the value 25 to variable xyz as 5*5=25. Then next statement is a function call to square() function passing xyz to this function in order to compute the square of 25. The output is:

625

Explanation:

The above code can also be written as:

xyz = 5*5

result = square(xyz)

print(result)

The difference is that xyz is assiged 5*5 which is equal to 25 so the output produced will be the same i.e.  625.

The result variable is used to store the value of square of 25 after the square() method computes and returns the square of 25. So print(result) prints the resultant value stored in the result variable i.e. 625

(d) is used by Ping

Explanation:

ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;

i. Requested service is not available

ii. Host could not be reached

ICMP does not use ports. Rather it uses types and codes. Some of the most common types are echo request and echo reply.

Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as Time Exceeded) to trace a network route.

Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP echo request packets to the host and then waits for an ICMP echo reply from the host.

ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

Explanation:

+41.50 = 0 10000100 01001100000000000000000  [single precision]

-72.125 = 1 10000000101 0010000010000000000000000000000000000000000000000000 [double precision]

(I) +41.50 using single precision

Follow the following steps:

(a) Single precision has 32 bits in total and is divided into three groups: sign (has 1 bit), an exponent (has 8 bits) and a mantissa (also called fraction, has 23 bits)

(b) Divide the number (41.50) into its whole and decimal parts:

Whole = 41

Decimal = 0.50

(c) Convert the whole part to binary:

2    |    41

2    |    20 r 1

2    |    10 r 0

2    |    5 r 0

2    |    2 r 1

2    |    1 r 0

     |    0 r 1

Reading upwards gives 41 = 101001₂

(d) Convert the decimal part to binary:

0.50 x 2 = 1.0  = 1 [number in front of decimal]

0.0 x 2 = 0.0 = 0  [number in front of decimal]

Reading downwards gives 0.5 = 10₂

(e) Put the two parts together as follows;

    101001.10₂

(f) Convert the result in (e) to its base 2 scientific notation:

Move the decimal to just before the leftmost bit as follows;

1.0100110

In doing so, we have moved over 5 numbers to the left. Therefore, the exponent is 5. Moving to the left gives a positive exponent while moving to the right gives a negative exponent.

Altogether we have;

1.0100110 x 2⁵

(g) Determine the sign bit of the number and display in binary: Since the number +41.50 is positive, the sign bit is 0.

(h) Determine the exponent bits.

Since this is a single precision conversion, the exponent bias is 127.

To get the exponent we add the exponent value from (e) to the exponent bias and get;

5 + 127 = 132

(i) Convert the exponent to binary:

2    |    132

2    |    66 r 0

2    |    33 r 0

2    |    16 r 1

2    |    8 r 0

2    |    4 r 0

2    |    2 r 0

2    |    1 r 0

     |    0 r 1

Reading upwards gives 132 = 10000100₂

(j) Determine the mantissa bits:

The mantissa is the rest of the number after the decimal of the base 2 scientific notation found in (f) above.

0100110 from 1.0100110 x 2⁵                  [Just remove the leftmost 1 and the decimal point]

(k) Combine the three parts: sign bit (1 bit), exponent bits (8 bits) and mantissa bits (23 bits)

sign bit = 0                [1 bit]

exponent bits = 10000100        [8 bits]

mantissa bits = 0100110        [7 out of 23 bits]

Then fill out the remaining part of the mantissa with zeros to make it 23 bits.

mantissa bits = 01001100000000000000000        

Putting all together we have

0 10000100 01001100000000000000000 as +41.50 in  a IEEE 754 single precision format.

(II) -72.125 using double precision

Follow the following steps:

(a) Double precision has 32 bits in total and is divided into three groups: sign (has 1 bit), an exponent (has 11 bits) and a mantissa (also called fraction, has 52 bits)

(b) Divide the number (72.125) into its whole and decimal parts:

Whole = 72

Decimal = 0.125

(c) Convert the whole part to binary:

2    |    72

2    |    36 r 0

2    |    18 r 0

2    |    9 r 0

2    |    4 r 1

2    |    2 r 0

2    |    1 r 0

     |    0 r 1

Reading upwards gives 72 = 1001000₂

(d) Convert the decimal part to binary:

0.125 x 2 = 0.25  = 0 [number in front of decimal]

0.25 x 2 = 0.50 = 0  [number in front of decimal]

0.50 x 2 = 1.00 = 1  [number in front of decimal]

0.00 x 2 = 0.00 = 0  [number in front of decimal]

Reading downwards gives 0.125 = 0010₂

(e) Put the two parts together as follows;

    1001000.0010₂

(f) Convert the result in (e) to its base 2 scientific notation:

Move the decimal to just before the leftmost bit as follows;

1.0010000010

In doing so, we have moved over 6 numbers to the left. Therefore, the exponent is 6. Moving to the left gives a positive exponent while moving to the right gives a negative exponent.

Altogether we have;

1.0010000010 x 2⁶

(g) Determine the sign bit of the number and display in binary: Since the number -72.125 is negative, the sign bit is 1.

(h) Determine the exponent bits.

Since this is a double precision conversion, the exponent bias is 1023.

To get the exponent we add the exponent value from (e) to the exponent bias and get;

6 + 1023 = 1029

(i) Convert the exponent to binary:

2    |    1029

2    |    514 r 1

2    |    257 r 0

2    |    128 r 1

2    |    64 r 0

2    |    32 r 0

2    |    16 r 0

2    |    8 r 0

2    |    4 r 0

2    |    2 r 0

2    |    1 r 0

     |    0 r 1

Reading upwards gives 1029 = 10000000101₂

(j) Determine the mantissa bits:

The mantissa is the rest of the number after the decimal of the base 2 scientific notation found in (f) above.

0010000010 from 1.0010000010 x 2⁶                  [Just remove the leftmost 1 and the decimal point]

(k) Combine the three parts: sign bit (1 bit), exponent bits (11 bits) and mantissa bits (52 bits)

sign bit = 1                [1 bit]

exponent bits = 10000000101    [11 bits]

mantissa bits = 0010000010        [10 out of 52 bits]

Then fill out the remaining part of the mantissa with zeros to make it 52 bits.

mantissa bits = 0010000010000000000000000000000000000000000000000000

Putting all together we have

1 10000000101 0010000010000000000000000000000000000000000000000000 as -72.125 in  a IEEE 754 double precision format.

Answer:

Here is the Python program.

def DigitList(number):  

   return sum(map(int, str(number)))  

list = [18, 23, 35, 43, 51]  

ascendList = sorted(list, key = DigitList)  

print(ascendList)

Explanation:

The method DigitList() takes value of numbers of the list as parameter. So this parameter is basically the element of the list. return sum(map(int, str(number)))  statement in the DigitList() method consists of three methods i.e. str(), map() and sum(). First the str() method converts each element of the list to string. Then the map() function is used which converts every element of list to another list. That list will now contain digits as its elements. In short each number is converted to the string by str() and then the digit characters of each string number is mapped to integers. Now these digits are passed to sum() function which returns the sum. For example we have two numbers 12 and 31 in the list so each digit is 1 2 and 3 1 are added to get the sum 3 and 4. So now the list would have 3 4 as elements.

Now list = [18, 23, 35, 43, 51] is a list of 5 numbers. ascendList = sorted(list, key = DigitList)  statement has a sorted() method which takes two arguments i.e. the above list and a key which is equal to the DigitList which means that the list is sorted out using key=DigitList. DigitList simply converts each number of list to a another list with its digits as elements and then returns the sum of the digits. Now using DigitList method as key the element of the list = [18, 23, 35, 43, 51] are sorted using sorted() method. print(ascendList) statement prints the resultant list with values in the list in ascending order sorted by the sum of their digits.

So for the above list [18, 23, 35, 43, 51] the sum of each number is 9 ,5, 8, 7, 6 and then list is sorted according to the sum values in ascending order. So 5 is the smallest, then comes 6, 7, 8 and 9. So 5 is the sum of the number 23, 6 is the sum of 51, 7 is the sum of 43, 8 is the sum of 35 and 9 is the sum of 18. So now after sorting these numbers according to their sum the output list is:

[23, 51, 43, 35, 18]

I am writing a JAVA program. Let me know if you want the program in some other programming language.

public class FourthRoot{ //class to calculate fourth root of 81

public static void main(String[] args) { //start of main() function body

   double square_root; //declares to hold the fourth root of 81

   double number=81; // number is assigned the value 81

/* calculates the fourth root of number using sqrt() method twice which means sqrt() of sqrt(). This is equivalent to pow(number,(0.25)) where pow is power function that computes the fourth root by raising the number 81 to the power of 0.25 which is 1/4 */

   square_root=Math.sqrt(Math.sqrt(number));

//displays the fourth root of 81 i.e. 3

     System.out.println("Fourth Root of 81 is "+ square_root); } }

Explanation:

The program is well explained in the comments given along with each statement of the program . Since it was the requirement of the program to user Math.sqrt() method so the fourth root of number= 81 is computed by taking the sqrt() of 81 twice which results in the fourth root of 81 which is 3.

So the first sqrt(81) is 9 and then the sqrt() of the result is taken again to get the fourth root of 81. So sqrt(9) gives 3. So the result of these two computations is stored in square_root variable and the last print statement displays this value of square_root i.e. the fourth root of number=81 which is 3.

Another way to implement the program is to first take sqrt(81) and store the result in a variable i.e. square_root. After this, again take the sqrt() of the result previously computed and display the final result.

public class FourthRoot{

   public static void main(String[] args) {

   double square_root;

   double number=81;

   square_root=Math.sqrt(number);

  System.out.println("Fourth Root of 81 is: "+ Math.sqrt(square_root)); } }

Explanation:

SONET is an acronym for synchronous optical networking while SDH is an acronym for synchronous digital hierarchy. They are both standard protocols used for the transmission of multiple digital bit streams (multiplex) synchronously through an optical fiber by using lasers.

Hence, both SONET and SDH are interoperable and typically the same standard protocols in telecommunication networks. Also, the SONET is a standardized protocol that is being used in the United States of America and Canada while SDH is an international standard protocols used in countries such as Japan, UK, Germany, Belgium etc.

The synchronous optical networking was developed in 1985 by Bellcore and it was standardized by the American National Standards Institute (ANSI). SDH was developed as a replacement for the plesiochronous digital hierarchy (PDH).

Generally, SONET comprises of four functional layers and these are;

1. Path layer

2. Line layer.

3. Section layer.

4. Physical or Photonic layer.

The SDH comprises of four synchronous transport modules and these are;

1. STM-1: having a basic data rate of 155.52Mbps.

2. STM-4: having a basic data rate of 622.08Mbps.

3. STM-16: having a basic data rate of 2488.32Mbps.

4. STM-64: it has a basic data rate of 9953.28Mbps.

These two standard telecommunications protocols are used to transmit large amounts of network data over a wide range through the use of an optical fiber.

LCD Power Adapter - This plugs into the wall to pull the electricity from the grid into your computer passing through AC Adapter.

On a side note... the most logical reason the computer could not be going over 15% nor charge anymore than 30mins is because the battery has been shortened by either a storm or a power surge.
