The "Introduction to Networking" room on “TryHackMe” covers fundamental networking concepts, including the OSI and TCP/IP models, basic networking tools, and essential networking theory. It serves as a foundational resource for those looking to understand networking principles and prepare for further studies in the field.

Key Topics Covered:

• OSI Model: The room explains the seven layers of the OSI model, which include Application, Presentation, Session, Transport, Network, Data Link, and Physical layers. Each layer has specific functions and responsibilities in the networking process.

• TCP/IP Model: It introduces the TCP/IP model, which is more compact than the OSI model and widely used in real-world networking. The TCP/IP model consists of four layers: Application, Transport, Internet, and Network Interface.

• Networking Tools: The room provides practical insights into essential networking tools such as ping, traceroute, whois, and dig, explaining their usage and significance in network troubleshooting and analysis.

• Encapsulation and De-encapsulation: The concepts of encapsulation (adding headers and trailers to data as it moves through the layers) and de-encapsulation (removing these as data is received) are discussed, highlighting their importance in data transmission.

• Practical Applications: Users are encouraged to apply their knowledge through hands-on tasks, reinforcing the theoretical concepts learned in the room.

NETWORKING CONCEPT'S

The "Networking Concepts" room on TryHackMe offers a comprehensive introduction to key networking principles, focusing on the OSI and TCP/IP models, essential protocols, and practical networking tools. It is tailored for beginners in cybersecurity, combining theoretical knowledge with hands-on exercises to enhance understanding.

Key Topics Covered:

• OSI and TCP/IP Models: The room outlines the seven layers of the OSI model (Application, Presentation, Session, Transport, Network, Data Link, and Physical) and contrasts them with the four layers of the TCP/IP model (Application, Transport, Internet, and Link).

• IP Addressing and Subnetting: It explains the structure of IP addresses, including the distinction between private and public IP ranges, subnetting concepts, and the importance of network and broadcast addresses.

• Transport Protocols: The differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are highlighted, focusing on their functionalities, connection methods, and typical use cases.

• Data Encapsulation: The concept of encapsulation is discussed, illustrating how data is packaged at each layer of the OSI model as it traverses the network.

• Hands-On Activities: Users participate in practical exercises using tools like telnet to connect to various services, reinforcing the theoretical concepts through real-world application.

HTTP IN DETAIL

The "HTTP in Detail" room on TryHackMe offers a friendly and practical introduction to how the web really works behind the scenes using the HTTP protocol. It breaks down various HTTP methods, such as GET, POST, PUT, and DELETE, explaining how clients communicate with servers to request and send data.

Key takeaways include:

• HTTP Basics: Understanding how requests and responses flow between your browser and web servers.

• Common Methods: Learning the purpose of GET (fetch data), POST (send data), PUT (update data), and DELETE (remove data).

• Response Codes: Getting familiar with status codes like 200 OK, 404 Not Found, and 500 Internal Server Error that tell you what happened with your request.

• Cookies & Headers: Discovering how cookies keep track of sessions and how headers provide important context during data exchanges.

• Practical Exercises: The room encourages hands-on practice sending different HTTP requests to build real-world skills in web communication and security.

🌐 DNS IN DETAIL

🔍 Navigating the internet smoothly wouldn’t be possible without DNS — the Domain Name System. This TryHackMe room dives into how DNS works behind the scenes, translating easy-to-remember domain names like tryhackme.com into the IP addresses that computers use to communicate. 🖥️➡️🔢

Highlights of the Room:

• DNS Basics: See how your computer first checks its own records before reaching out to recursive DNS servers to find website IPs.

• DNS Hierarchy: Explore the powerful chain of servers — from root servers to Top-Level Domain (TLD) servers and Authoritative Name Servers — that help direct your requests.

• DNS Records & TTL: Understand the data stored about domains and how TTL (Time To Live) determines how long this info stays valid.

• Hands-on with Dig: Get practical experience by using the dig tool to query DNS servers and analyze the responses yourself.
