Explore key network layer protocols (IP, ARP, RARP, ICMP, IGMP) and technologies (Routing, NAT). Understand their functions and test your knowledge with practice questions.
A comprehensive guide to key network technologies for certification exams (Wi-SUN, NFC, Bluetooth, SDN, NFV, MEC, IoT, MQTT, Zigbee), including an analysis of why Ad-hoc Networks are on the test.
Learn core concepts, operating principles, and differences of SSO (Single Sign-On), Kerberos, and OAuth. Compare features and pros/cons of each authentication technology with practical exam problems.
Explore everything about IPSec, the core network security protocol. Clearly understand the differences between AH and ESP, and the operational methods of Transport Mode and Tunnel Mode. Test your knowledge with practice questions for certification exams.
Learn the basic concepts of Denial of Service (DoS) attacks and their differences from Distributed Denial of Service (DDoS) attacks. This post also explains the principles and mechanics of Distributed Reflection Denial of Service (DRDoS), an amplification attack method. Includes practice problems for the engineer exam.
Explains the characteristics and differences between the two main data transmission methods in networks: packet switching and circuit switching. Provides a comparative analysis of datagram and virtual circuit methods in packet switching, as well as the differences between connectionless and connection-oriented communication.
A systematic overview of routing protocols in the network layer. This guide covers the differences between static and dynamic routing, the distinction between Interior Gateway Protocols (IGP) and Exterior Gateway Protocols (EGP), and detailed characteristics and algorithms of RIP, OSPF, and BGP based on the concept of Autonomous Systems (AS).
Explains subnet masks and subnetting in IPv4. Covers calculating network, host, and broadcast addresses, CIDR notation, and includes practice problems for certification.
