Answer:
1. DMZ (Demilitarized zone)
Explanation:
In computer networking, a Demilitarized Zone is a physical or logical network designed to give an extra layer of security on the organization’s private network. The DMZ acts as an interface between an untrusted network such as the internet and the organization’s internal network. When a server is set up in a demilitarized zone, users can reach it via its public IP address. In case there is an attack on the server, the private network is still protected.
The correct answer is MAC (Media Access Control).
<h3>What is MAC?</h3>
The Media Access Control (MAC) protocol is a data link layer protocol that defines the process by which local area network (LAN) devices interface with upper network layer protocols, such as the Internet Protocol (IP).
The MAC protocol is responsible for controlling access to the shared communication medium of the LAN and for providing a reliable link between devices on the LAN. It does this by defining a set of rules and procedures for how devices on the LAN can detect and avoid collisions when transmitting data, as well as for how they can recover from errors that may occur during transmission.
The MAC protocol is typically implemented in hardware, such as in the network interface controller (NIC) of a computer, and is an essential part of the LAN communication process.

Answer:
number = int(input("Enter number: "))
if (number % 4):
print("{} is not divisible by 4".format(number))
else:
print("{} is divisible by 4".format(number))
Explanation:
If the %4 operation returns a non-zero number, there is a remainder and thus the number is not divisable by 4.
