TryHackMe's "What is Networking?" 

What is Networking?

Definition: A network is a collection of interconnected devices that communicate with each other using defined rules and protocols.

Examples:

• Your group of friends (connected by interests, hobbies, etc.)
• A city's public transportation system
• The internet (a vast network of interconnected computers)

Types of Networks

• Private Network: A network owned and operated by a single organization or individual (e.g., your home network).
• Public Network: A network accessible to the public (e.g., the internet).

How Devices Communicate on a Network

IP Addresses: Unique numerical identifiers assigned to each device on a network.

MAC Addresses: Physical hardware addresses that uniquely identify each network interface card (NIC).

Protocols: Sets of rules that govern how data is transmitted and received over a network.

Key Networking Concepts

• Internet: The global network of interconnected computers and networks.
• Router: A device that forwards data packets between different networks.
• Switch: A device that directs data packets within a single network.
• Firewall: A security device that controls network traffic to and from your computer.
