What is IP address DNS firewall wi-Fi

Let's define those terms for you.

• IP Address: An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing. Think of it like a postal address for your device on the internet.

• DNS: DNS (Domain Name System) is like the phonebook of the internet. It translates human-readable domain names (like www.google.com) into machine-readable IP addresses (like 172.217.160.142) that computers use to identify each other. Without DNS, you'd have to remember long strings of numbers to visit websites.

• Firewall: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks (like the internet), preventing unauthorized access and protecting against malicious attacks.

• Wi-Fi: Wi-Fi is a wireless networking technology that allows devices such as computers, mobile devices, and other equipment to connect to the internet or communicate with each other wirelessly within a particular area. It uses radio waves to transmit data, enabling mobility and convenience without physical cables.
