Introduction to Networking
Computer networking is the practice of connecting multiple computing devices—such as PCs, servers, routers, and IoT gadgets—to facilitate communication and resource sharing over wired or wireless links Think of networks as digital road systems where nodes (devices) exchange data via links, following agreed-upon rules called protocols
2. Network Types
2.1. NETWORK TOPOLOGY
Network topologies describe the physical or logical arrangement of connected devices in a network. There are several common types, each with unique advantages and disadvantages. A network topology describes the arrangement of devices and connections in a network, defining how data flows between nodes.
Bus Topology
In a bus topology, all devices are connected to a single central cable, or "backbone." Data travels along this backbone in both directions, and a terminator is placed at each end to absorb the signal and prevent it from bouncing back. All devices are connected to a single central cable (the "bus"). Data travels along the bus, and each device checks if the data is intended for it.
