ENG 211: Computer Networks and Security

Description

Comprehensive study material on the architecture of computer networks and the essential protocols for digital security. This document covers how devices communicate across distances and the tools used to protect data from malicious threats. Key Highlights: - Network Fundamentals: Definition of workstations and the primary goals of networking, resource sharing (hardware and software). - Network Classifications: Categorization of networks based on transmission media (wired vs. wireless), topology, and geographical scale (LAN, MAN, WAN). - Network Topologies: Analysis of physical layouts including Bus, Star, Ring, and Mesh, with their respective pros and cons. - Network Hardware: Roles of critical components like NICs (Network Interface Cards), Switches, Routers, and Modems. - The OSI Model: A detailed look at the 7-layer Open Systems Interconnection model for standardized communication. - Cybersecurity Essentials: Introduction to network threats (Viruses, Worms, Trojans) and defense mechanisms such as Firewalls and Antivirus software.
