tähtiverkkona

Tähtiverkkona is a Finnish term that translates to "star network" in English. In the context of computer networking, a star network is a topology where all devices are connected to a central hub or switch. Each device has a dedicated point-to-point connection to the central node. If any device needs to communicate with another device, it sends its data to the central hub, which then forwards it to the intended recipient.

The advantages of a star network include its ease of installation and management. Adding or removing devices is straightforward, as it only requires connecting or disconnecting a single cable to the central hub. If one cable fails, only the affected device is disconnected; the rest of the network remains operational. Troubleshooting is also simpler because the problem can often be isolated to a specific device or its connection.

However, star networks also have drawbacks. The entire network's functionality depends on the central hub or switch. If the central device fails, the entire network goes down. This can make it a single point of failure. Additionally, star networks can be more costly in terms of cabling, as each device requires its own cable run back to the central point. The performance of the network can also be limited by the capacity of the central hub.
