Answer:
Technology has profoundly changed education in many ways. Technology has greatly expanded access to education. In medieval times, books were rare and only an elite few had access to educational opportunities. Individuals had to travel to centers of learning to get an education. Today, massive amounts of information (books, audio, images, videos) are available at one’s fingertips through the Internet, and opportunities for formal learning are available online worldwide through online learning, podcasts, traditional online degree programs, and more. Access to learning opportunities today is unprecedented in scope thanks to technology.
Technology is a gift of God. After the gift of life, it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts, and sciences. Technology has certainly changed the way we live. It has impacted different facets of life and redefined living. Undoubtedly, technology plays an important role in every sphere of life. Several manual tasks can be automated, thanks to technology. Also, many complex and critical processes can be carried out with ease and greater efficiency with the help of modern technology. Thanks to the application of technology, living has changed and it has changed for the better. Technology has revolutionized the field of education. The importance of technology in schools cannot be ignored. In fact, with the onset of computers in education, it has become easier for teachers to impart knowledge and for students to acquire it. The use of technology has made the process of teaching and learning all the more enjoyable.
Technology has also begun to change the roles of teachers and learners. In the traditional classroom, the teacher is the primary source of information, and the learners passively receive it. This model of the teacher as the “sage on the stage” has been in education for a long time, and it is still very much in evidence today. However, because of the access to information and educational opportunity that technology has enabled, in many classrooms today we see the teacher’s role shifting to the “guide on the side” as students take more responsibility for their learning using technology to gather relevant information. Schools and universities across the country are beginning to redesign learning spaces to enable this new model of education, foster more interaction and small group work, and use technology as an enabler.

Answer:
The fastest way to obtain the revocation status of digital certificate of the website is by using Online certificate Status Protocol (OSCP).
Explanation:
Online certificate status protocol is the protocol that help user to check and verify the digital certificate revocation status. This protocol is linked with the digital certificate issuance authority. Whenever someone want to verify the status of the digital certificate that is attached to access the website. The website administrator can send the request to OSCP handler to ensure the status of the certificate. The OSCP handler is connected through certificate issuance authority, send the detail to verify the status. After verifying the status, OSCP handler respond as certificate is valid or revoked to the concerned user.

Explanation:
class Employee
{
String name;
double salary;
void tostring()
{
System.out.println("Employee:\nName: "+name+"\nSalary: "+salary+"\n");
}
Employee(String n,double s)
{
name=n;
salary=s;
}
}
class Manager extends Employee
{
String department;
void tostring()
{
System.out.println("Manager:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");
}
Manager(String n,double s,String d)
{
super(n,s);
department=d;
}
}
class Executive extends Manager
{
void tostring()
{
System.out.println("Executive:\nName: "+name+"\nDepartment: "+department+"\nSalary: "+salary+"\n");
}
Executive(String n,double s,String d)
{
super(n,s,d);
}
}
public class test
{
public static void main(String args[])
{
Employee e =new Employee("Neo",12000);
e.tostring();
Manager m =new Manager("Cramster",100000,"Homework");
m.tostring();
Executive ex =new Executive("Chuks",1000000,"Homework");
ex.tostring();
}
}
Answer:
4. Supervised learning.
Explanation:
Supervised and Unsupervised learning are both learning approaches in machine learning. In other words, they are sub-branches in machine learning.
In supervised learning, an algorithm(a function) is used to map input(s) to output(s). The aim of supervised learning is to predict output variables for given input data using a mapping function. When an input is given, predictions can be made to get the output.
Unsupervised learning on the other hand is suitable when no output variables are needed. The only data needed are the inputs. In this type of learning, the system just keeps learning more about the inputs.
Special applications of supervised learning are in image recognition, speech recognition, financial analysis, neural networking, forecasting and a whole lot more.
Application of unsupervised learning is in pre-processing of data during exploratory analysis.
