What kind of topology is used by network that connects all its computers and communications devices to a central server?

The topology used in a network that connects all its computers and communication devices to a central server is called a star topology. In this configuration, each device is connected individually to a central hub or switch, allowing for efficient data transmission and easy management. If one connection fails, it does not affect the rest of the network, making it a reliable choice for many setups. However, if the central hub fails, the entire network becomes inoperable.
