The difference between internal method call and external method call are as follows:-
Internal Method calls means when the function is called using the object of the class in the same class which is defined but where as in case of external method , itcalls the function are called from other class by creating the object the respected class in other class and the function is called .
Suppose there is only one class and that class is only having all the methods and function declaration and there is no other class described . So in this case we will use the internal Method calls only .
It would be, <span>the <span>microprocessor. </span></span> It is also a multipurpose and programmable device that accepts inputted data and process the data to provide an output.
We can use a packet filtering firewall, for something like this, reasons because when visiting a site these types of firewalls should block all incoming traffic and analyze each packet, before sending it to the user. So if the packet is coming from a malicious origin, we can then drop that packet and be on our day ;D
