What do you mean? I’m confused with the question, it doesn’t make sense:)
Answer: A- Public Key Encryption
Explanation: The Public key Encryption is used prevalently on the web, it allows for secure messages to be sent between parties without having to agree on, or share, a secret key. It uses an asymmetric encryption scheme in which the encryption key is made public, but the decryption key is kept private.
<span>You typically import data for the following reasons: You want to merge two databases by copying all the objects in one database to another. [ When you import, you can copy all the tables, queries, forms, reports, macros, and modules, along with table relationships, to another database in a single operation. You need to create some tables that are similar to tables that exist in another</span>
Answer:
public class Calculator {
public double add(int a, int b){
return a+b;
}
public double substract(int a, int b){
return a-b;
}
public double multiply(int a, int b){
return a*b;
}
public double divide(int a, int b){
if(b>0){
return a/b;
}
else{
System.out.println("Cannot divide by zero");
}
return -1;
}
}
Explanation:
- Using Java Programming Language, the class Calculator is created. There are no fields (Instance variables) and no constructors since these are not required by the question.
- Four methods (functions) are created: add, substract, multiply and divide as specified in the question.
- Note the use of the if statement in the divide() to handle case of illegal division (by 0)
The answer is : 0.0.0.0 In DHCP, 0.0.0.0 is reserved for use by clients that are not yet configured with an IP address. <span>The IP address 0.0.0.0 indicates different uses at different places. Usually, it’s a non-routable meta address that’s not bound to any particular remote address. Dealing with servers, it means all IPv4 addresses in the local machine.</span>
