A firewall is a security system that filters network traffic based on set rules. It blocks or allows data between trusted and untrusted networks to prevent unauthorized access, hacking, malware, and DoS attacks, helping protect systems and data from cyber threats. .

3 Networking Concepts For Your INTERVIEW 🌐 DNS translates names into IP addresses. Ports help your machine know which service to talk to. NAT allows private machines to communicate with the public internet securely. In one simple flow: DNS finds the server. Port identifies the service. NAT enables communication. That’s the real networking path most interviewers want to see you understand. Follow for more interview concepts! . .

🟢 This image explains the main components of a network rack and how data and power flow inside a structured network. It shows a complete rack setup with labeled devices arranged vertically for efficient operation and management. At the top, the Router connects the internal network to the Internet ( WAN ). Below it, the Firewall provides security by filtering and protecting network traffic. The Network Switch manages LAN traffic and distributes connections to multiple devices. The Patch Panel is used for cable termination and organization, ensuring clean and structured cabling. Servers provide network services such as applications, file storage, and databases. For power management, the rack includes a UPS ( Uninterruptible Power Supply ) that provides backup power during outages, and a PDU ( Power Distribution Unit ) that distributes electricity to all devices. At the bottom, cooling and cable management systems maintain proper airflow and reduce heat. The diagram also illustrates the complete network flow : #Internet → #Router → #Firewall → #Switch → #Patch_Panel → End Devices ( PCs, printers, access points ). Overall, the image presents a clear and professional overview of how a network rack is organized and how data and power move through the system.
