Understanding Network Protocols

TCP/IP Basics

The TCP/IP protocol suite is the foundation of internet communications. Common protocols include TCP for reliable data transfer, UDP for fast messaging, and IP for routing.

Application Protocols

Higher-level protocols like HTTP, DNS, and SMTP operate on top of TCP/IP. These protocols define how applications communicate and exchange data.

Network Analysis

Packet analysis helps diagnose network issues, monitor performance, and understand application behavior. Look for patterns in timing, errors, and protocol usage.
