Question

in a(n) ___ topology, all nodes are connected to a hub or switch and communicate through it. options: fiber, mesh, bridge, star

Explanation:

In a star topology, all nodes are connected to a central hub or switch. This central device acts as a communication point. Other topologies like mesh (nodes connected to multiple others), bridge (used for connecting networks, not a topology type here), and fiber (a medium, not a topology) don't match the description.

Answer:

star
