The document provides an overview of network topology, detailing the arrangement of network devices and their connections, which affects data flow within a network. It describes various types of network topologies, including bus, star, ring, and mesh, highlighting their characteristics, advantages, and applications. Additionally, it emphasizes the importance of understanding these topologies for designing efficient networks.

4. Introduction to Network Topology
• Network Topology refers to the arrangement of network devices (like computers,
routers, and switches) and how they are connected to each other.
• It determines the structure of a network, including how data flows between devices.
• Understanding and distinguishing different network topology with each of its use
case would helps in designing efficient networks.

• Physical Topology
• Describes the placement of each component in the network and how they are
physically connected.
• Logical Topology
• Describes how network devices appear to be connected to each other and how
data flows through the network.

8. Common Topologies
Network topology diagrams are a key tool for administrators to map out the most
efficient placement of nodes and connections within a network. Rather than creating
from scratch, they often choose from several established topologies, including point-
to-point, bus, ring, star, tree, mesh, and hybrid configurations.

Bus Topology
• Devices are connected to a single central cable called bus. Data travels along the
bus, and each device checks if the data is intended for it.
• It like how Hub previously worked in Layer 2, but now abandoned due to its security
concerns.
• Easy to install, less cable.
• Difficult to fix and not efficient for scalability.

10. Star Topology
• Devices are connected to a central switch. The switch acts as a repeater, forwarding
data to the correct device.
• Easier to manage.
• Requires more cables.

11. Ring Topology
• Devices are connected in a circular formation, and data travels in one direction
around the ring until it reaches its destination.
• Simple to install and data flow is intuitive.
• Break in the ring can disrupt the entire network.

12. Mesh Topology
• Every device is connected to every other device in the network. This creates multiple
paths for data to travel.
• High reliability.
• Expensive and complex.

14. Application of Big Data
• Bus Topology
• Widely used in small networks.
• Star Topology
• Commonly found in home and office networks.
• Ring Topology
• Used in industrial control systems, where devices are interconnected in a ring to
monitor and control processes.
• Mesh Topology
• Found in mission-critical networks where reliability is crucial, such as military
communication systems and Internet backbone infrastructure.
• Known as ad-hoc
