Answer:
Check the explanation
Explanation:
An entity can be a person, place, thing, or even an event about which data is collated and stored. Entities names usually are nouns.
The Entity Data Model (EDM) is an extensive model of the Entity-Relationship model which identifies the conceptual model of the data using a variety of modeling technique. It acan also be termed as a set of concepts that illustrates data structure, regardless of its stored form.
The Information stored or can be stored in a CASE repository regarding an entity includes:
Name
Definition
Special Notes
Because machine (cpu) can only execute machine code(language).
Answer: A. Voice over Internet Protocol
B. It reduces the delay for all objects requested by a user.
Explanation:
Voice over Internet Protocol is used to transfer voice communication and multimedia over the internet. It converts voice into a digital signal, transfers it over the internet and then reconverts it to voice when it reaches its destination.
Web Caching stores the data from a web page for reuse at a later time, this helps to reduce the tasks the server carries out and reduces delay. Because some objects are cached, more resources can be focused on objects that are not thereby reducing delay for all objects requested by a user.
Answer: Constructors can specify parameters but not return types.
Explanation:
public class Student {
int roll_no;
public Student(int a) {
roll_no = a;
}
public static void main(String[] args) {
Student abs = new Student(10);
System.out.println(abc.roll_no);
}
}
In the above code we have illustrated the working of constructors. We have a class with the name Student. then a constructor is created of the class called as the class constructor. In the main we create an object of the class and with this object we invoke the constructor and also pass a parameter. Here in the code we are passing the roll no of the student.
So we can say that constructor is called during the runtime when the object created invokes the constructor so a constructor can have many arguments but it does not have a return type.
Well the only one that is actually a piece of programming is A. Word Processing Program. B, C and D are all peripherals for a computer not actual software for it. Basically if you have to install it on the computer its software. Now B C and D may need software to make them compatible with your computer they themselves dont need to be installed.
