About this course
Computer Networks — GATE CS / IT
23 chapters and 128 content pieces covering the GATE Computer Networks syllabus end-to-end. Topics include the OSI / TCP-IP layered model, physical and data-link layer (framing, error detection, CSMA/CD), network layer (IP addressing, subnetting, routing algorithms), transport layer (TCP, UDP, flow and congestion control), and application layer protocols (DNS, HTTP, SMTP, FTP).
Networks GATE questions tend to be a mix of conceptual (protocol behaviour) and numerical (subnetting, sliding-window calculations, RTT-based throughput). Every chapter pairs concept with calculation. The PYQ section is organised by layer so you can revise top-to-bottom or bottom-up.
