It is a (software) program that is installed on a computer without the user's knowledge for the purpose of making harmful changes. A computer virus attaches itself to another program (the execution of the host program triggers the action of the virus). And most of them perform actions that are malicious in nature, such as destroying data. A computer virus operates in two ways: As soon as it lands on a new computer, begins to replicate or it plays dead until the trigger kick starts the malicious code. The term 'computer virus' was formally defined by Fred Cohen in 1983.
Answer:
A computer virus is a virus attached onto your computer, and it gives you bugs and can often delete your important files.
import java.util.Scanner;
public class JavaApplication41 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String language = scan.nextLine();
if (language.toLowerCase().equals("java")){
System.out.println("Awesome!");
}
else if (language.toLowerCase().equals("python")){
System.out.println("A very simple language!");
}
else if (language.toLowerCase().equals("ruby")){

}
else if (language.toLowerCase().equals("javascript")){

I hope this helps!
Answer:
The UDP server described needed only one socket, whereas the TCP server needed two sockets because:
Answer:
UDP uses one socket and TCP requires two sockets in a transmission because UDP is a way one connectionless protocol but TCP is connection oriented.
The TCP server that supports n simultaneous connections would require n sockets, ranging from 1 through n.
Explanation:
A socket is a fusion of a port number and a source IP address using a colon.
UDP is a transport layer protocol that is unreliable, because it does not need to establish connection to transmit packets and does not retransmit dropped packets. TCP is another transport layer protocol that is reliable, establish connection and retransmit dropped packets.
For a UDP, only one socket would be created to transmission. A socket on the client side and server side would be created in TCP connection. A server can have multiple sockets for one or different transmission protocols.
Answer:
Must use mutators to initialize class data.
May use assignment statements to initialize class data.
Explanation:
These are the two characteristics that are present in constructors. A constructor is an instance method of a class or structure that creates an object of the class to which it belongs. This is mostly used in object-oriented programming. These constructors usually have the same name as the actual class, and can be used in order to set the values of the members of an object.
b. #include
c. #include container
d. #include deque
Answer:
d.#include deque
Explanation:
We have to include deque library in order to use a deque container and the syntax to include is #include<deque>.Deque is a double ended queue which is a sequence container and allows operations of contraction and expansion on both ends of the queue.Double ended queues are a special case of simple queue since in simple queue the insertion is from rear end and deletion is from front end but in deque insertion and deletion is possible at both ends rear and front.
Answer:
The answer is "Intranet".
Explanation:
The intranet becomes an information exchange computer network, in which the resources collaborate with OS and other computing infrastructure within the organization. It is usually done without access from third parties and primarily uses for analysis of the data.
Here, the NMCI links the computer network of navy and maritime bodies on the bases of both the boats and the regional offices, that's why we can say that it is the example of the Internet.
