Computer Networks
Class 12 Computer Science Interactive Learning Workbook: Master networking evolution (ARPANET to Internet), data communication components, bandwidth vs transfer rate, switching techniques, wired media (twisted pair, coaxial, optical fiber), wireless media (radio, microwave, infrared), network devices (modem, NIC, hub, switch, router, gateway), topologies (bus, star, tree), protocols (HTTP, HTTPS, FTP, SMTP, POP3, TCP/IP, VoIP), web services, HTML vs XML, domain names, URLs, browsers, hosting, and systematic network troubleshooting across 10 structured modules.
Course Chapters & Learning Modules
Total 10 interactive modules with guided checkpoint challenges.
Module 1: Computer Networks and Their Evolution
Understand the fundamentals of computer networks, trace network history from ARPANET and NSFNET to the modern Internet, and distinguish the Internet from the World Wide Web.
Module 2: Data Communication, Capacity, IP and Switching
Master the 5 elements of data communication, differentiate bandwidth from actual data transfer rate, understand IP addressing, and compare circuit switching with packet switching.
Module 3: Wired Transmission Media
Compare guided physical transmission media: twisted-pair (UTP/STP), coaxial cable, and fibre-optic cables across speed, distance, cost, and electromagnetic interference (EMI).
Module 4: Wireless Transmission Media
Explore unguided electromagnetic transmission: compare radio waves, microwaves, and infrared signals across frequency, coverage, line-of-sight requirements, and obstacles.
Module 5: Network Devices and Connectors
Understand the roles of core networking hardware: Modem, NIC (Ethernet/Wi-Fi), RJ45 connector, Repeater, Hub, Switch, Router, and Gateway.
Module 6: Network Types and Topologies
Classify networks by geographical span (PAN, LAN, MAN, WAN) and master physical network topologies: Bus, Star, and Tree topologies.
Module 7: Network Protocols: Web, Email, Transfer and Voice
Master essential networking protocols: HTTP, HTTPS, FTP, SMTP, POP3, Telnet, PPP, TCP/IP suite, and VoIP, matching protocols to real-world tasks.
Module 8: Web Services: WWW, HTML, XML and Names
Understand web service technologies: World Wide Web architecture, HTML structure vs XML data transport, Domain Names, DNS resolution, and URL anatomy.
Module 9: Browsers, Servers, Hosting and Web Flow
Trace end-to-end web request flows from browser URL entry to server response, understand web hosting paradigms, and differentiate client browsers from web servers and search engines.
Module 10: Network Review: Choose, Trace and Troubleshoot
Synthesize end-to-end networking concepts, master systematic layer-by-layer network troubleshooting, select appropriate network architectures, and complete the comprehensive Checkpoint Exam.
