stjärntopologi

Stjärntopologi is a network topology where all devices are connected to a central hub or switch. This central point acts as a server, and all data traffic passes through it. Each device in the network has its own dedicated connection to the central hub, resembling the spokes of a wheel radiating from a central axle.

In a stjärntopologi, if one cable connecting a peripheral device fails, only that specific device is affected. The rest of the network continues to function normally. However, if the central hub or switch fails, the entire network goes down. This makes the central device a single point of failure.

Setting up and managing a stjärntopologi is generally straightforward. Adding or removing devices is easy, as it only involves connecting or disconnecting a single cable from the central hub. Troubleshooting is also simplified because the failure of a single connection is easily isolated to a specific device or cable.

Stjärntopologi is widely used in modern local area networks (LANs), particularly in homes and small to medium-sized businesses, due to its ease of implementation and management. The cost of cabling can be higher compared to some other topologies because each device requires its own cable run to the central point.
