Answer:
The main method should simply terminate if the FileNotFoundException occurs.
Explanation:
Considering the full code snippet
snippet:public static void main(String[] args) throws FileNotFoundException
public static void main(String[])
represent the entry point method to a java main method
The addition of
throws FileNotFoundException
widens the scope of the main method to explicitly specifies that an exception named the FileNotFoundException may be thrown.
So, if any part of the code explicitly throws the FileNotFoundException the compiler makes use of this to throw an exception.
By throwing an exception, the main method is not catching any exceptions, instead it handles the FileNotFoundException by throwing it to the source which invoked the main method
This is required by the compiler to terminate the program if the FileNotFoundException occurs.
Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
