अगर आप पॉलिटेक्निक 3rd सेमेस्टर Computer science / IT Engineering के छात्र हैं, तो यह वीडियो Computer Networks विषय को समझने के लिए बेहद जरूरी है।

इस वीडियो में आपको मिलेगा BTEUP 2025 Odd Semester के अनुसार अपडेटेड नया syllabus और Unit-wise explanation, जिसमें हम कवर करेंगे:

UNIT 1: Introduction :
Introduction to computer networks; Network Models- OSI Reference Model, TCP/IP Model;
Practical Exercise
1. Study of any Network simulation tool (Wireshark, Cisco Packet Tracer, NS-2, GNS3 etc)
2. To understand and practically observe how the data travels through OSI layers using network
tools (Wireshark, Cisco Packet Tracer, NS-2, GNS3 etc)

UNIT 2: Data Communication and Communication Methodologies :
Transmission Media – principles, issues and examples; Wired Media – Coaxial, UTP, STP, Fiber
Optic Cables; Wireless Media – HF, VHF, UHF, Microwave, Ku Band; Network topologies; Data
Link Layer – design issues, example protocols (Ethernet, WLAN, Bluetooth); Switching Techniques (Circuit, Packet, Message)
Practical Exercise
1. Showing various types of networking cables and connectors, identifying them clearly
2. Looking at specifications of cables and connectors of various companies on Internet, find out differences.
3. Making patch cords using different types of cables and connectors - crimping, splicing, etc
4. Demonstration of different type of cable testers, using them for testing patch cords pre- pared by
the students in Lab and standard cables prepared by professionals

UNIT 3: Network Layer :
Network Layer – design issues, example protocols (IPv4); Concept of IPV6, Routing principles /
issues, algorithms (Distance - vector, Link-state) and protocols (RIP, OSPF);
Practical Exercise
1. Configuring computing devices (PC, Laptop, Mobile, etc) for network, exploring different options and their impact – IP address, gateway, DNS, security options, etc

UNIT 4: Transport Layer:
Transport Layer – design issues, example protocols (TCP/UDP); Application Layer Protocols (SMTP,
DNS)
Practical Exercise
1. TCP communication between two devices

UNIT 5: Network Devices
Functioning of Network Devices – NIC, Hub, Bridge, Switch, Router, WiFi Devices; Network
Management System and example protocol (SNMP).
Practical Exercise
1. Showing various networking devices – NICs, Hub, Bridge, Switch, Router, Gateway, WiFi access
point, etc.
2. Looking at specifications of various networking devices various companies on Internet, find out
differences.
