Such topology is called star.
Star Topology WAN
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.

It is called a Star topology
point-to-point
The three most commonly used wide area network (WAN) topologies are point-to-point, hub-and-spoke, and mesh. In a point-to-point topology, a direct connection is established between two locations, providing a simple and efficient link. The hub-and-spoke model connects multiple remote sites to a central hub, facilitating easier management and data flow. Mesh topology involves interconnecting multiple nodes directly, allowing for redundancy and resilience, as each node can communicate with multiple others.
A star topology is a type of mathematical topology. Mathematical topology is essentially geometry without concern for distance. It asks questions such as for a given shape, (in the abstract sense) "what connects to what," "is it possible to reach point x from point y without passing through point z," and "are these two points connected at all?" A star topology is a type of topology where all the points (for example, computers in a computer network) are connected to a central point, but not directly to each other. Go to the following address to see several types of network topologies, including a star topology. http://scilnet.fortlewis.edu/tech/Network/Topologies.htm
The topology you're describing is known as a star topology. In a star topology, all network devices are connected to a central hub or switch, which acts as the main point of communication. If this central point fails, the entire network becomes inoperable, as no devices can communicate with each other. This design is often used for its simplicity and ease of troubleshooting, but it does create a single point of failure.
