Computer Networking Complete Master Series
Computer ScienceAn 11-part visual study guide covering network topologies, hardware devices, OSI & TCP/IP models, media, protocols, IP addressing, security, and cloud architecture.
Fundamentals & Types of Computer Networks
Core definitions of computer networking, 5 primary objectives (*Communication, Resource Sharing, Reliability, Remote Access, Cost Efficiency*), and comparison matrix with diagrams for PAN, LAN, MAN, and WAN.
🔒 Open in the StudoKe app Bus, Star & Ring Topologies
Layout arrangements, advantages, disadvantages, and visual diagrams for Bus topology (*main cable*), Star topology (*central switch*), and Ring topology (*circular token flow*).
🔒 Open in the StudoKe app Mesh, Tree & Hybrid Topologies
Full mesh redundancy, hierarchical tree backbone structures, department-level hybrid topologies, and an introductory summary of core interconnecting devices.
🔒 Open in the StudoKe app * Network Hardware & Interconnection Devices
Detailed visual hardware sketches and functions for NICs, Hubs, Switches, Routers, Repeaters, Bridges, Modems, Access Points, and Firewalls.
🔒 Open in the StudoKe app Transmission Media & Core Protocols
Guided media (*twisted-pair, coaxial, fiber-optic*) vs unguided wireless signals, Wi-Fi access points, and essential network protocol definitions (*TCP, UDP, IP, HTTP, DNS, DHCP, FTP*).
🔒 Open in the StudoKe app OSI Model, TCP/IP & Subnetting
7-layer OSI model, 4-layer TCP/IP framework, IPv4 vs IPv6 address structures, and subnetting divisions for network organization.
🔒 Open in the StudoKe app Network Services, DORA & Port Numbers
Default Gateways, DNS domain-to-IP translation, DHCP 4-step DORA assignment process, TCP vs UDP comparison, and common port number references (*22, 25, 53, 80, 443*).
🔒 Open in the StudoKe app Security, Diagnostics & CLI Commands
* Network security controls, wireless standards (*3G/4G/5G, Wi-Fi*), step-by-step troubleshooting workflows, and essential CLI commands (`ping`, `tracert`, `ipconfig`, `nslookup`). ####
🔒 Open in the StudoKe app Topologies Comparison & Client-Server Architecture
* Side-by-side comparison matrix of all network topologies, network scale summaries, and request-response client-server architecture dynamics. ####
🔒 Open in the StudoKe app Cloud Computing, VPNs & Firewalls
Email/FTP file transfer, cloud computing infrastructure, Network Management Systems (NMS), hardware/software firewalls, and encrypted VPN tunnels.
🔒 Open in the StudoKe app Wireless Security, Threats & Network Design
WPA2/WPA3 wireless security, common threats (*malware, phishing, DoS, MitM*), bandwidth vs throughput metrics, network monitoring tools, and enterprise network design best practices.
