Network Topology Basics

Network Topology

• Network topology refers to the physical and logical arrangement of devices and connections within a network.

Physical Topology

• Physical topology refers to the physical arrangement of devices and connections within a network, such as the layout of cables and devices.
• In the OSI model, a network's physical topology is a concern of the Physical Layer (Layer 1).

Logical Topology

• A logical topology characteristic is the flow of data between devices, which can be different from the physical layout of the network.
• An example of a logical topology is a bus topology, where all devices connect to a single cable.

LAN Topology

• An example of a physical topology found in LANs is a star topology, where all devices connect to a central device, such as a switch or hub.

Sustainable Development Goals (SDGs)

• The Sustainable Development Goals (SDGs) are also known as the Global Goals.
• SDG 6 focuses on ensuring access to clean water and sanitation for all.
• The SDGs were created in 2015, replacing the Millennium Development Goals in the global development framework.
• The primary focus of the SDGs is to end poverty, protect the planet, and ensure peace and prosperity for all.
