Answer:

a. 7 bits

b. 8 bits

c. 9 bits

d. 24 bits

Explanation:

Required

Number of bits per word

The formula to get the number of bits per word is:

[tex]2^n = N[/tex]

Where

n = bits

N = numbers

Solving (a) 0 to 100

There are 101 digits between 0 and 100 (inclusive)

So:

[tex]N = 101[/tex]

Substitute 101 for N in [tex]2^n = N[/tex]

[tex]2^n = 101[/tex]

101 can not be expressed as an exponent of 2.

So, we substitute 101 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 128[/tex]

Express 128 as an exponent of 2

[tex]2^n = 2^7[/tex]

Apply law of indices

[tex]n = 7[/tex]

Hence, 7 bits are required

Solving (b): 0 through 255

There are 256 digits between 0 and 255 (inclusive)

So:

[tex]N = 256[/tex]

Substitute 256 for N in [tex]2^n = N[/tex]

[tex]2^n = 256[/tex]

Express 256 as an exponent of 2

[tex]2^n = 2^8[/tex]

Apply law of indices

[tex]n = 8[/tex]

Hence, 8 bits are required

Solving (c): 0 through 256

There are 257 digits between 0 and 256 (inclusive)

So:

[tex]N = 257[/tex]

Substitute 257 for N in [tex]2^n = N[/tex]

[tex]2^n = 257[/tex]

257 can not be expressed as an exponent of 2.

So, we substitute 257 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 512[/tex]

Express 512 as an exponent of 2

[tex]2^n = 2^9[/tex]

Apply law of indices

[tex]n = 9[/tex]

Hence, 9 bits are required

Solving (d): 0 through 10000000

There are 10000001 digits between 0 and 10000000 (inclusive)

So:

[tex]N = 10000000[/tex]

Substitute 10000000 for N in [tex]2^n = N[/tex]

[tex]2^n = 10000000[/tex]

10000000 can not be expressed as an exponent of 2.

So, we substitute 10000000 for the closest number greater than 101 that can be expressed as an exponent of 2.

So:

[tex]2^n = 16777216[/tex]

Express 16777216  as an exponent of 2

[tex]2^n = 2^{24[/tex]

Apply law of indices

[tex]n = 24[/tex]

Hence, 24 bits are required

Answer:

A. an instance of the same data is stored in two or more places in the database.

Explanation:

Giving that Update Anomalies usually occur when the designated user person in keeping records or record master stored a particular data in more than one in a database. This is what is called duplication of data and is termed an irregularity on the part of the record keeper.

Hence, the correct answer to the question is " A. an instance of the same data is stored in two or more places in the database."

Answer:

Data field.

Explanation:

In Computer Networking, data encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).

Basically, an Ethernet Frame is one of the IEEE 802.3 data encapsulation standards.

An Ethernet Frame can be defined as the building blocks or bits contained in a single packet of data that is being transmitted over an Ethernet network or connection. When data are transmitted, a frame check sequence (FCS) containing a 4-bytes is used to detect or check for any error in a frame and to ensure no frame data was corrupted in the course of the transmission.

In the transmission control protocol (TCP), all frames that are being transmitted must have a minimum of 64-bytes in length and as such when small packets are encapsulated, some additional bits referred to as pad are typically used to increase the frame size to at least 64-bytes, which is the minimum size.

Hence, a data field is the part of an Ethernet Frame that uses a pad to increase the frame field to at least 64 bytes.

Answer:

A. Relative cell reference.

Explanation:

A relative cell reference is like a pointer to a cell or range of cell in Excel. In Excel all cell references, by default, are relative cell references.

In the given instance, the cell address A4 in a formula means it is a relative cell reference. If there would have been a $ sign before A4, then it will be an absolute cell reference. But since, it is without dollar sign, it is a relative cell reference.

Therefore, option A is correct.

Answer:

Selection structure.

Explanation:

In a decision structure (selection structure), there is a branch forward at some point, which causes a portion of the program to be skipped. A loop structure (repetition structure) contains a branch to a previous statement in the program module, which results in a block of statements that can be executed many times.

Answer:

Ping the other workstations from the IT Admin workstation to confirm that connection has been lost, check the status of the network interface card in the workstation with command ifconfig in the terminal, then reset the connection using ifdown and ifup commands. If the problem is not resolved, check the cable connection.

Explanation:

Ping is an ICMP echo message sent by a network host to another to check for connectivity. If they are connected, the other workstation responds with an ICMP response message.

The ifconfig in Linux systems displays the network adapters and their individual IP configurations. If there is no connection even after the network is reset, then the cable connectors could be the problem.

Explanation:

It's the other way round actually. Arraylists do not have fixed size and can increase or decrease in size as needed. On the other hand, Arrays are fixed from when they are declared; they have a particular size that number of elements cannot go beyond.

An arraylist in Java is a class that is part of a Java collection framework(java.util) that can have variable sizes and only store objects, not primitive data like strings or integers. An array is a data structure in Java and can store both primitive data and objects, while having a fixed size at declaration.

Answer:

public static boolean isVowel(String word){

   char vowels= word.toLowerCase(word.charAt(i));

       if (vowels== "a" || vowels == "e" || vowels== "i" || vowels == "o" ||  vowels == "u" ){

          return true;

       } else {

           return false;

       }

  }

}

Explanation:

The Java source code analyzes each character in a string object and returns true if it is a vowel letter.

Answer:

Method overriding.

Explanation:

In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.

Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.

A class can inherit behavior from a parent but also define its own and override parent behavior. This is called method overriding.

Method overriding occurs when there are two (2) methods with the same method parameter and name. The parent class handles one of the methods while the other is in the child class.

Hence, method overriding allows a child class to define its own specific implementation of a method and override parent behavior.

             System.out.print("Enter number of items: ");

             secdN += in.nextInt();

             totalT += sTime * secdN;

             total += sPrice * secdN;

             break,

         case 3:

             tPrice = 5.99;

             tTime = 12;

             System.out.print("Enter number of items: ");

             thirdN += in.nextInt();

             totalT += tTime * thirdN ;

             total += tPrice * thirdN;

             break,

        default:

             System.out.println("Looking forward to the Weekend");

       }

       System.out.print("Do you want to end the order? y/n: ");

       isEnd = in.nextLine();

   }

   System.out.println("Number of Type 1 candles bought : "+firstN);

   System.out.println("Number of Type 2 candles bought : "+secdN);

   System.out.println("Number of Type 3 candles bought : "+thirdN);

   System.out.println("Total cost is : "+total);

   System.out.println("Total burn time is : "+totalT);

   double costPerBurn = (totatT * 60) / total;

   System.out.println("Cost per minute : "+ costPerBurn);

 }

}

Explanation:

The Java program creates a continuous for-loop statement that gets the candle type, price and amount ordered from a switch and accumulates the total cost and burn time of the candles bought and the cost per minute burn of the candles consecutively.

int main(){

   char number[100];

   printf("Number: ");

   scanf("%s", number);

   int sum = 0;

   for(int i =0;i<strlen(number);i++){

       sum+= number[i] - '0';

   }

           printf("Sum: %d",sum);

   return 0;

}

Explanation:

This declares a c string of 100 characters

   char number[100];

This prompts user for input

   printf("Number: ");

This gets user input

   scanf("%s", number);

This initializes sum to 0

   int sum = 0;

This iterates through the input string

   for(int i =0;i<strlen(number);i++){

This adds individual digits

       sum+= number[i] - '0';

   }

This prints the calculated sum

           printf("Sum: %d",sum);

   return 0;

The program that ask the user to enter a series of single digit number and display the sum of all the single digit number, highest number and lowest number is as follows:

x = input("input the series of number: ")

y = []

for i in x:

  y += i

integer_map = list(map(int, y))

print(sum(integer_map))

print(max(integer_map))

print(min(integer_map))

The code is written in python.

Answer:

function is a self-contained program segment that carries out some specific, well-defined task. Every C program consists of one or more functions. One of these functions must be called main. Execution of the program always begins by carrying out the instructions contained in main. Note that if a program contains multiple functions then their definitions may appear in any order. The same function can be accessed from several different places within a program. Once the function has carried out its intended action, control is returned to the point from which the function was accessed. Generally speaking, a function processes information passed to it from the calling portion of the program, and returns a single value. Some functions, however, accept information but do not return anything.

A function definition has two principal components: the first line (including the argument declarations), and the so-called body of the function.

The first line of a function takes the general form data-type  name(type 1  arg 1,  type 2  arg 2,  ...,  type n  arg n)

where data-type represents the data type of the item that is returned by the function, name represents the name of the function, and type 1, type 2, ..., type n represent the data types of the arguments arg 1, arg 2, ..., arg n. The allowable data types for a function are:

int       for a function which returns an integer value

double    for a function which returns an floating-point value

void      for a function which does not return any value

The allowable data types for a function's arguments are int and double. Note that the identifiers used to reference the arguments of a function are local, in the sense that they are not recognized outside of the function. Thus, the argument names in a function definition need not be the same as those used in the segments of the program from which the function was called. However, the corresponding data types of the arguments must always match.

The body of a function is a compound statement that defines the action to be taken by the function. Like a regular compound statement, the body can contain expression statements, control statements, other compound statements, etc. The body can even access other functions. In fact, it can even access itself--this process is known as recursion. In addition, however, the body must include one or more return statements in order to return a value to the calling portion of the program.

A return statement causes the program logic to return to the point in the program from which the function was accessed. The general form of a return statement is:

return  expression;

This statement causes the value of expression to be returned to the calling part of the program. Of course, the data type of expression should match the declared data type of the function. For a void function, which does not return any value, the appropriate return statement is simply:

return;

A maximum of one expression can be included in a return statement. Thus, a function can return a maximum of one value to the calling part of the program. However, a function definition can include multiple return statements, each containing a different expression, which are conditionally executed, depending on the program logic.

Note that, by convention, the main function is of type int and returns the integer value 0 to the operating system, indicating the error-free termination of the program. In its simplest form, the main function possesses no arguments. The library function call exit(1), employed in previous example programs, causes the execution of a program to abort, returning the integer value 1 to the operating system, which (by convention) indicates that the program terminated with an error status.

The program segment listed below shows how the previous program factorial.c can be converted into a function factorial(n) which returns the factorial (in the form of a floating-point number) of the non-negative integer n:

double factorial(int n)

{

 /*

    Function to evaluate factorial (in floating-point form)

    of non-negative integer n.

 */

 int count;

 double fact = 1.;

 /* Abort if n is negative integer */

 if (n < 0)

  {

   printf("\nError: factorial of negative integer not defined\n");

   exit(1);

  }

 /* Calculate factorial */

 for (count = n; count > 0; --count) fact *= (double) count;

 /* Return value of factorial */

 return fact;      

}

The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.

public static void uniqueWords() {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a sentence:");

       String sentence = in.nextLine();

       String words[] = sentence.split(" ");

       ArrayList<String> uniqueWords = new ArrayList<>();

       for (int x = 0; x < words.length; x++) {

           boolean exists = false;

           for (int i = 0; i < uniqueWords.size(); i++) {
