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:

Without it information flow is impossible

Explanation:

The word 'pivotal' also means crucial or vital, and so we need to consider what an operating system actually does.

Remember, merely having all the hardware of a computer would not allow you to run (install and use) programs. It is by means of an operating system that teaching programs can be installed, and it is also by means of an operating system learning can take place.

For example, a student can decode (learn) instructions/lessons from his teacher via a software program; and the software program needs an operating system to open (run) the program.

Answer:

class PatientData():    #declaration of PatientData class

   height_inches=0  #attribute of class is declared and initialized to 0

   weight_pounds=0 #attribute of class is declared and initialized to 0

Explanation:

Here is the complete program:

#below is the class PatientData() that has two attributes height_inches and weight_pounds and both are initialized to 0

class PatientData():  

   height_inches=0

   weight_pounds=0  

patient = PatientData()  #patient object is created of class PatientData

#below are the print statements that will be displayed on output screen to show that patient data before

print('Patient data (before):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')

#below print  statement for taking the values height_inches and  weight_pounds as input from user

patient.height_inches = int(input())  

patient.weight_pounds = int(input())  

#below are the print statements that will be displayed on output screen to show that patient data after with the values of height_inches and weight_pounds input by the user

print('Patient data (after):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')      

Another way to write the solution is:

def __init__(self):

       self.height_inches = 0

       self.weight_pounds = 0

self keyword is the keyword which is used to easily access all the attributes i.e. height_inches and weight_pounds defined within a PatientData class.

__init__ is a constructor which is called when an instance is created from the PatientData, and access is required to initialize the attributes height_inches and weight_pounds of PatientData class.

The program along with its output is attached.

In this exercise we have to use the knowledge of computational language in python to describe a code, like this:

The code can be found in the attached image.

To make it easier the code can be found below as:

class PatientData():  

  height_inches=0

  weight_pounds=0  

patient = PatientData()

print('Patient data (before):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')

patient.height_inches = int(input())  

patient.weight_pounds = int(input())  

print('Patient data (after):', end=' ')

print(patient.height_inches, 'in,', end=' ')

print(patient.weight_pounds, 'lbs')

Open ended investigation

Explanation:

The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.

From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions

The sequential data or sequence data is described as data that come in an ordered sequence. It may also be termed data that is produced from tasks that occurs in sequential order The sequential pattern mining is a critical subject in data mining that has do with applying sequential data to derive a statistically relevant pattern from it.

Sequential pattern mining is a part of data mining. Data mining involves utilizing data from databases to understand and make decisions that better the organization or society as a whole based on this. Common data mining tasks include: clustering, classification, outlier analysis, and pattern mining.

Pattern mining is a kind of data mining task that involves explaining data through finding useful patterns from data in databases. Sequential pattern mining is pattern mining that uses sequential data as a source of data in finding data patterns. Sequential pattern mining applies various criteria(which maybe subjective) in finding "subsequence" in data. Criteria could be :frequency, length, size, time gaps, profit etc. Sequential pattern mining is commonly applicable in reality since a sizeable amount of data mostly occur in this form. A popular type of sequential data is the time series data.

Answer:

When we add another bit, the amount of numbers we can make multiplies by 2. So a two-bit number can make 4 numbers, but a three-bit number can make 8.

The amount of numbers that can be made is multiplied by two for each bit to be added.

The bit is the most basic unit for storing information. Bits can either be represented as either 0 or 1. Data is represented by using this multiple bits.

The amount of numbers that can be gotten from n bits is given as 2ⁿ.

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.
