This course is designed for anyone who aspires to become a Network Security Engineer, Network Security Architect, or Cyber Security Engineer.

Lesson Overview

In this lesson, we will explore the fundamental concepts of networking, which are crucial for understanding how data is transmitted between devices. Networking involves connecting computers and other devices to share resources such as files, printers, and internet access. This process includes data transmission via cables, wireless signals, or a combination of both.

Lesson Structure

We will cover several key concepts, beginning with computer components, which form the foundation of digital communication. Next, we will explore different types of networks to enhance your understanding of commonly used network types and their architectural designs. We will then take an in-depth look at the OSI model, which outlines the standards for data flow. Additionally, we will examine IP addressing, which provides unique identifiers for each device on a network. Furthermore, we will discuss the roles of routers and switches in directing traffic and managing data flow. Finally, we will delve into security concepts and secure protocols, which are sets of rules that govern secure and reliable communication between devices.
