Course Content

Introduction to Computer Networks
Covers what computer networks are, their purpose, benefits, types, and common use cases. It introduces basic networking concepts like clients, servers, protocols, and data transmission.

Networking Models (OSI and TCP/IP)
Explains the 7-layer OSI model and the 4-layer TCP/IP model. Helps understand how data flows through different layers and the functions of protocols at each layer.

Network Topologies and Architectures
Discusses physical and logical layouts like star, bus, ring, mesh, and hybrid topologies. Also includes client-server and peer-to-peer architectures.

Types of Networks (LAN, WAN, MAN, PAN)
Introduces network classifications based on size and function: LAN: Local Area Network WAN: Wide Area Network MAN: Metropolitan Area Network PAN: Personal Area Network

IP Addressing (IPv4 & IPv6)
Teaches addressing rules, structure, classes, and formats for IPv4 and IPv6. Covers private/public IPs, static/dynamic assignment, and addressing schemes.

Subnetting and VLSM
Explains how to divide a network into subnets for better management. Introduces Variable Length Subnet Masking for efficient IP allocation.

Routing Fundamentals and Protocols (RIP, OSPF, BGP)
Covers the basics of how routers move packets between networks and compares common routing protocols: RIP (distance-vector), OSPF (link-state), BGP (path vector for the internet backbone).

Switching Concepts and VLANs
Explores Layer 2 switching, MAC address tables, and Virtual LANs (VLANs) to segment networks and reduce broadcast domains.

Wireless Networking (Wi-Fi Standards and Security)
Covers wireless standards (802.11a/b/g/n/ac/ax), Wi-Fi architecture, and wireless security (WPA2, WPA3, SSID, WPS).

Network Hardware (Routers, Switches, Firewalls, Access Points)
Describes the function, types, and configurations of essential network devices used in enterprise and home environments.

Network Security Fundamentals (Firewall, VPN, IDS/IPS)
Introduces core security devices and concepts, such as perimeter firewalls, endpoint protection, Virtual Private Networks, and Intrusion Detection/Prevention Systems.

Network Services (DHCP, DNS, NAT, SNMP)
Explains common network services: DHCP: Automatically assigns IP addresses DNS: Resolves domain names NAT: Shares one public IP across multiple devices SNMP: Monitors and manages networked devices

Network Troubleshooting Tools and Techniques
Covers tools like ping, tracert, nslookup, ipconfig, netstat, and protocol analyzers. Teaches how to diagnose and resolve common connectivity issues.

Cloud Networking and Virtualization Basics
Explains how networks work in cloud environments and virtualized platforms. Introduces SDN, virtual switches, and cloud service providers like AWS, Azure, GCP.

Monitoring and Performance Optimization
Covers network performance metrics and tools like Wireshark, NetFlow, and PRTG. Discusses identifying bottlenecks and optimizing bandwidth usage.

Remote Access and VPN Technologies
Explores how users connect securely from remote locations using VPNs (SSL, IPSec), RDP, SSH, and remote desktop tools.

Network Policies and Documentation
Teaches how to create network policies, standard operating procedures (SOPs), diagrams, and documentation for network layout, asset tracking, and auditing.

Cybersecurity in Networking (Threats & Mitigation)
Discusses common threats (DDoS, spoofing, MITM, ransomware), best practices (patching, firewalls, user training), and layered security approaches.

Hands-on Labs and Certification Practice Exams
Provides simulations and real-world labs to apply knowledge, plus practice exams to prepare for certifications like CompTIA Network+, Cisco CCNA, and more.
