An overview of the layered TCP/IP model, illustrating how each layer (physical, data link, network, transport, and application) interacts to enable end‑to‑end communication.

TCP/IP Protocol Layering

Detailed breakdown of each protocol layer, highlighting key functions and representative protocols such as IP, TCP, UDP, and ICMP.

Transmission Media Overview

Explanation of common physical media (copper, fiber, wireless) and their characteristics, including bandwidth, attenuation, and typical use cases.

Ethernet Frame Structure

Diagram of Ethernet frame fields (preamble, MAC addresses, EtherType, payload, CRC) and their role in LAN communication.

IP Addressing

Fundamentals of IPv4 addressing, subnet masks, CIDR notation, and address allocation strategies.

ICMP Protocol

Purpose of the Internet Control Message Protocol, common message types (Echo Request/Reply, Destination Unreachable) and diagnostic uses.

ARP Protocol

How the Address Resolution Protocol maps IP addresses to MAC addresses within a local network.

Transport Layer Protocols

Comparison of TCP and UDP, their reliability mechanisms, flow control, and typical application scenarios.

Routing Basics

Introduction to routing concepts, including route tables, next‑hop selection, and the distinction between static and dynamic routing.

Static Routing Fundamentals

Configuration steps for manually defining routes, advantages for small networks, and limitations.
