Answer:
It is A: Packet metadata is used to route and reassemble information travelling through the internet.
Explanation:
Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee
Step 2: Entering the network
Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.
Step 3: Taking flight
The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.
Step 4: BGP
These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.
Step 5: Finding a route
This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.
Step 6: Bad information
For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.
Last step: Arrival
The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

Answer:
// program in java.
// package
import java.util.*;
// class definition
class Main
{// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read inputs
Scanner scr=new Scanner(System.in);
// variables
String name;
double price;
System.out.print("Enter item's name: ");
// read item's name
name = scr.next();
System.out.print("Enter item's price: ");
// read item's price
price= scr.nextDouble();
// print name
System.out.println("name of item is:"+name);
// print price
System.out.println("price of item is:"+price);
}catch(Exception ex){
return;}
}
}
Explanation:
Read name & price of item from user and assign it to variables "name" & "price" respectively with scanner object.Then print the name and price of item .
Output:
Enter item's name: Apple
Enter item's price: 100
name of item is:Apple
price of item is:100.0
