Which of the following is considered the most common form of network topology?

The star topology is considered the most common form of network topology due to its simplicity and reliability. In a star topology, all devices are connected to a central hub or switch, which enables easier management and troubleshooting of the network. If one connection fails, it does not affect the entire network, as the other devices remain operational. This makes it an ideal choice for both small and large networks.

Moreover, star topology facilitates easy addition of new devices without disrupting the existing network, thereby allowing for greater scalability as the organization grows. The maintenance tasks, like cable management or device replacement, are also simplified, as most issues can be localized to a single connection to the hub. This combination of ease of use, reliability, and maintainability is why star topology is widely adopted in various computing environments.
