Emerging technology is a term given to the development of new technologies or improvement on existing technologies that are expected to be available in the nearest future.

Examples of emerging technologies includes but not limited to block chain, internet of things, robotics, cognitive science, artificial intelligence (AI) etc.

One of the reasons that makes emerging technology happen is the quest to improving on existing knowledge. People want to further advance their knowledge in terms of coming up with newest technologies that would make task faster and better and also address human issues. For instance, manufacturing companies make use of robotics,design, construction, and machines(robots) that perform simple repetitive tasks which ordinarily should be done by humans.

Other reasons that makes emerging technology happens are economic benefit, consumer demand and human needs, social betterment, the global community and response to social problems.

Impact that emerging technology will have on;

• Individuals. The positive effect of emerging technology is that it will create more free time for individuals in a family. Individuals can now stay connected, capture memories, access information through internet of things.

• Society. Emerging technology will enable people to have access to modern day health care services that would prevent, operate, train and improving medical conditions of people in the society.

• Environment. Before now, there have been global complains on pollution especially on vehicles and emission from industries. However, emerging technology will be addressing this negative impact of pollution from vehicles as cars that are currently being produced does not use petrol which causes pollution.

what makes ''emerging technologies'' happen is the necessity for it, the need for it in the society.

The impact they will have on individuals ,society,and environment is that it will improve areas of life such as communication, Transportation, Agriculture.

Emerging technologies can be regarded as the technologies in which their development as will as practical applications are not yet realized.

Answer:

\n

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.    

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r")  #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.    

The readline() method reads one line and the print method displays that line.

Prediction

With regard to preparedness for hazard/disaster, technology such as AI are being explored to see how they can help to predict natural disaster.

If there is a breakthrough in this space, it will drastically reduce the negative impact of natural disasters such as floods and earthquakes as people will become ready to respond to them and mitigate their effects where possible.

In agriculture, there are factors which come together to bring about flooding. Flooding is one of the major disasters which cripples entire value chains. With a potential threat anticipated or predicted by AI, businesses can invest in technologies that can help protect the farms, farmland and other resources critical to such a supply chain.

AI-powered technologies that provide prediction services often combine this advanced computing prowess with the ability to process big data.

Technology can reach places that are unreachable by humans

AI-powered robots will soon become the norm.

Presently there are self-learning and self instructing robots powered by Artificial Intelligence that have applications in warfare, manufacturing, deepsea diving and intelligence gathering, and transportation. It is not out of place to predict that in the next decade, scientists would have perfected rescue robots that can go into very unstable terrain that have been damaged by flood or earthquake and attempt a rescue of lives and property at a scale that has never been possible before.

Connectivity  

Connectivity helps people access to aid, resources that are critical for survival, transmission and receipt of life--saving information etc. CISCO has successfully used its technology called TacOps (short for Tactical Operations) successfully 45 times on over 5 continents.

The answer is "0 to 4294967295"

Explanation:

Given bit:

32 bits

Calculating smallest and largest bits:

In any processor, it works only on the 0 and 1 bit and it also stores 0 and 1 values. so, the smallest address in bit value is= 0 and the largest bit value can be defined as follows:

largest address value in bits:

[tex]\Longrightarrow 2^{32}-1\\\\\Longrightarrow 4294967296 -1\\\\\Longrightarrow 4294967295\\\\[/tex]

smallest address= 0

largest address = 4294967295

Answer:

A) Number of bits for byte = 6 bits

B) number of bits for index = 17 bits

C) number of bits for tag = 15 bits

Explanation:

Given data :

cache size = 64 kB

block size = 32 -byte

block address = 32 -bit

number of blocks in cache memory  

cache size / block size = 64 kb / 32 b = 2^11 hence the number of blocks in cache memory = 11 bits = block offset

A) Number of bits for byte

[tex]log _{2} (6)^2[/tex] = 6  bits

B) number of bits for index

block offset + byte number

= 11 + 6 = 17 bits

c ) number of bits for tag

= 32 - number of bits for index

= 32 - 17 = 15 bits

Answer:

"this" keyword representing the class object itself.

Explanation:

Object-oriented programming concept emphasizes on using blueprints representing the structure of a data collection type to continuously create an instance of that data structure. The instance of that object is called a class object. It is used in database management systems to populate the database.

Functions defined in the class objects are called methods and are used specifically by the class instance to modify the data content of the class object defined.

When a member of a class is referenced in the class, it can be accessed with the "this" keyword. At an instance of the class object, the variable holding the object should be called to get the class content because of the "this" keyword binding the instance of the object to the method.

Answer:

There are no statements in the question, so I explained the whole code.

Explanation:

A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.

For example, map.put("123", "John Smith");   -> key = 123, value = John Smith

Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.

Note that the key 222 also has Steve Yao for the value, that is totally acceptable.

Answer:

The class definition for Javascript:

var Class = {

      arguments of the class object are initialized here;

}

This class definition for Python:

class "class_name"( object ):

      def __init__(self, arguments are passed are and initialized after the closing parenthesis)

Explanation:

Object-oriented programming languages are vital tools in creating data structures that are meant to be changeable, unindexed but directly accessible knowing the key value, and has unique membership.

This clearly is an adoption of the set data structure rule in creating a data structure blueprint that can be instantiated anytime in the code.

Complete Question:

In which type of hacking does the user block access from legitimate users without actually accessing the attacked system?

Group of answer choices

a. Denial of service

b. Web attack

c. Session hijacking

d. None of the above

Answer:

a. Denial of service

Explanation:

Denial of service (DOS) is a type of hacking in which the user (hacker) blocks access from legitimate users without actually accessing the attacked system.

It is a type of cyber attack in which the user (an attacker or hacker) makes a system or network inaccessible to the legitimate end users temporarily or indefinitely by flooding their system with unsolicited traffic and invalid authentication requests.

A denial of service is synonymous to a shop having a single entry point being crowded by a group of people seeking into entry into the shop, thereby preventing the legitimate customers (users) from exercising their franchise.

Under a DOS attack, the system or network gets stuck while trying to locate the invalid return address that sent the authentication requests, thus disrupting and closing the connection. Some examples of a denial of service attack are ping of death, smurf attack, email bomb, ping flood, etc.

Answer:

a)  

int apples [5] = {2, 4, 6, 8, 10};

b)

int *aPtr   //this is the pointer to int

Another way to attach a pointer to a an int variable that already exists:

int * aPtr;

int var;

aPtr = &var;

c)

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

       cout << values[i] << endl;    }

d)  

   aPtr = values;

   aPtr = &values[0];    

both  the statements are equivalent

e)

If its referring to the part d) then the address is:

cout<<aPtr;

f)

     for (int i = 0; i < size; ++i) {

            cout<<*(vPtr + i)<<endl;    }

g)

   cout << (aPtr + 3) << endl;  // address referenced by aPtr + 3

   cout << *(aPtr + 3) << endl; // value stored at that location

This value stored at location is 8

h)

    aPtr = &apples[4];

    aPtr -= 4;

    cout<<aPtr<<endl;

    cout<<*aPtr<<endl;  

Explanation:        

a)

int apples [5] = {2, 4, 6, 8, 10};

In this statement the array names is apples, the size of the array is specified in square brackets. so the size is 5. The type of array apples is int this means it can store integer elements. The values or elements of the array apples are even integers from 2 to 10. So the elements of array are:

apples[0] = 2

apples[1] = 4

apples[2] = 6

apples[3] = 8

apples[4] = 10

b)

In this statement int *aPtr  

The int* here is used to make the pointer aPtr points to integer object. Data type the pointer is pointing to is int. The asterisk symbol used with in makes this variable aPtr a pointer.

If there already exists an int type variable i.e. var and we want the pointer to point to that variable then declare an int type pointer aPtr and aPtr = &var; assigns the address of variable var to aPtr.

int * aPtr;

int var;

aPtr = &var;

c)

The complete program is:

int size= 5;

int values[size] = {2,4,6,8,10};

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

       cout << values[i] << endl; }

The size of array is 5. The name of array is values. The elements of array are 2,4,6,8,10.

To print each element of the values array using array subscript notation, the variable i is initialized to 0, because array index starts at 0. The cout statement inside body of loop prints the element at 0-th index i.e. the first element of values array at first iteration. Then i is incremented by 1 each time the loop iterates, and this loop continues to execute until the value of i get greater of equal to the size i.e. 5 of values array.

The output is:

2

4

6

8

10

d)

aPtr = values;

This statement assigns the first element in values array to pointer aPtr. Here values is the address of the first element of the array.

aPtr = &values[0];    

In this statement &values[0] is the starting address of the array values to which is assigned to aPtr. Note that the values[0] is the first element of the array values.

e)

Since &values[0] is the starting address of the array values to which is assigned to aPtr. So this address is the physical address of the starting of the array. If referring to the part d) then use this statement to print physical address is aPtr pointing to

cout<<aPtr;

This is basically the starting address of the array values to which is assigned to aPtr.

The output:

0x7fff697e1810                

f)

i variable represents offset and corresponds directly to the array index.

name of the pointer i.e. vPtr references the array

So the statement (vPtr + i) means pointer vPtr that references to array values plus the offset i array index that is to be referenced. This statement gives the address of i-th element of values array. In order to get the value of the i-th element of values array, dereference operator * is used.  It returns an ith value equivalent to the address the vPtr + i is pointing to. So the output is:

2

3

6

8

10

g)

values[0] is stored at 1002500

aPtr + 3 refers to values[3],

An integer is 4 bytes long,

So the address that is referenced by aPtr + 3 is

1002500 + 3 * 4 = 1002512

values[3] is basically the element of values array at 3rd index which is the 4th element of the array so the value stored at that referred location  is 8.

h)

Given that aPtr points to apples[4], so the address stored in aPtr is

1002500 + 4 * 4 = 1002516

aPtr -= 4  is equivalent to aPtr = aPtr - 4

The above statement decrements aPtr by 4 elements of apples array, so the new value is:

1002516 - 4 * 4 = 1002500

This is the address of first element of apples array i.e 2.

Now

cout<<aPtr<<endl; statement prints the address  referenced by aPtr -= 4 which is 1002500  

cout<<*aPtr<<endl;  statement prints the value is stored at that location which is 2.

   for(int i = word.length() - 1; i>=0; i--)

 {

     stringreverse+=word[i];

 }

 cout<<stringreverse;

}

int main()

{

 string user_input;

 cout << "Enter a string:  ";

 getline (std::cin, user_input);

 getstring(user_input);

 return 0;

}

Explanation:

The method starts here

void getstring(string word)

{

This line initializes a string variable to an empty string

   string  stringreverse = "";

This iteration iterates through the character of the user input from the last to the first

   for(int i = word.length() - 1; i>=0; i--)   {

     stringreverse+=word[i];

 }

This line prints the reversed string

 cout<<stringreverse;

}

The main method starts here

int main()

{

This line declares a string variable for user input

 string user_input;

This line prompts the user for input

 cout << "Enter a string:  ";
