Question 21

What does DNS server stand for and what does it do over the internet?

Answer 21

A DNS server stands for Domain Name System Server. Since domain names serve as memorizable names over the Internet and computers use IP addresses to access websites, DNS translates domain names into IP addresses, allowing us to access an Internet connection by its domain name.

Question 22

What are firewalls and how are they similar to a real firewall that can be found in buildings?

Answer 22

A firewall is a system that controls incoming and outgoing network traffic to determine what data should be allowed through, based on a set of rules. Firewalls are similar to real firewalls because they prevent outsiders or outside data from entering into your own network.

What are 2 types of firewalls and their locations?

Answer 23

The two types of firewalls are host-based firewalls and network-based firewalls. The host based firewall is a software that can be downloaded on the computer and the network-based firewall is a firewall that comes in between the internet and the private network.
