Computer Networks Lab (23IT5352)
WEEK 1
Date: 26/06/2025
Roll Number: 238W1A1296
Aim:
To draw and implement different network topologies (Bus, Star, Ring, Mesh, and Hybrid) using
Cisco Packet Tracer.
Apparatus/Software Required:
Cisco Packet Tracer software
Computer system with Windows/Linux OS
Procedure:
1. Bus Topology:
Definition: In bus topology, all devices are connected to a single central cable, called the
bus.
Construction Steps:
o Open Cisco Packet Tracer.
o Add multiple end devices (PCs).
o Connect all devices using a single straight-through cable.
o Use hubs or repeaters if necessary.
o Assign IP addresses to each device.
Output:
2. Star Topology:
Definition: In star topology, all devices are connected to a central hub or switch.
Construction Steps:
o Open Cisco Packet Tracer.
o Add end devices (PCs) and a switch.
o Connect each PC to the switch using straight-through cables.
o Assign IP addresses to each PC.
Output:
3. Ring Topology:
Definition: In ring topology, each device is connected to exactly two other devices,
forming a ring.
Construction Steps:
o Add multiple PCs in a circular arrangement.
o Connect each PC to its two neighbors using crossover cables.
o Assign IP addresses.
Output:
4. Mesh Topology:
Definition: In mesh topology, every device is connected to every other device.
Construction Steps:
o Add multiple PCs.
o Connect each PC to every other PC using individual cables.
o Assign IP addresses accordingly.
Output:
5. Hybrid Topology:
Definition: Hybrid topology is a combination of two or more different topologies.
Construction Steps:
o Create two or more topologies (e.g., star + bus).
o Connect them using appropriate network devices.
o Assign IPs and simulate connectivity.
Output:
Result:
The different network topologies were successfully created and simulated using Cisco Packet
Tracer.
