Week 1
History of Computing & Computer Systems Architecture
Evolution: Mechanical Era (Babbage), Vacuum Tubes (ENIAC), Transistors, Microprocessors & Modern era
Computer Categorization: Supercomputers, Mainframes, Workstations, PCs & Embedded Systems
IT Infrastructure Pillars: Physical Hardware, Software Operating Systems, and Network Connectivity
Hardware vs. Software Symbiosis: The Piano & Music analogy
Practical: Identifying system components, storage arrays & peripheral architecture
Week 2
Cybersecurity Landscape & Core Network Foundations
The Cybersecurity Landscape: Common threats (Malware, Phishing, Ransomware)
The 'CIA Triad' of Information Security: Confidentiality, Integrity, and Availability
What is a Network & Networking? Data transmission and resource sharing
Core Device Differences: Hubs (Broadcast to all) vs. Switches (Targeted MAC delivery) vs. Routers (Inter-network routing)
Practical: Mapping school, office, and home network devices
Week 3
Network Topologies, Types & Data Units
Network Types: LAN (Local), WAN (Internet), MAN (City-wide), and PAN (Bluetooth/Wi-Fi devices)
Network Topologies: Point-to-Point, Bus (Backbone risk), Star (Central switch), Ring, Mesh & Hybrid topologies
Data Units Hierarchy: Bit (0/1), Byte (8 bits), Frames (Data Link), and Packets (Network)
Data Segmentation vs. Data Fragmentation across network transmission
Real-Life Observation Lab: Wi-Fi device congestion, router positioning & speed bottleneck troubleshooting
Week 4
The 7-Layer OSI Model, Protocols, Ports & How the Internet Works
The ISO OSI 7-Layer Model: Physical, Data Link, Network, Transport, Session, Presentation, Application
Network Security Devices: Firewalls, Wireless Access Points (WAP), VLAN segmentation & NAT IP translation
Common Ports: HTTP (Port 80), HTTPS (Port 443), SSH (Port 22), FTP (Port 21)
Step-by-Step Web Request Lifecycle: DNS lookup, NAT translation, Router forwarding, and OSI encapsulation
Practical: Designing a full multi-device LAN diagram with Router, Switch, Laptop, Phone and Printer
