Final answer:
Hubs in an Ethernet network using 10Base-T standard operate at half-duplex and can face collisions, as they cannot send and receive data simultaneously.
Explanation:
When considering an Ethernet network using the 10Base-T standard where network devices are connected together using hubs, it is accurate to state that Hubs operate at half-duplex. This means they can either send or receive data at any given time, but not simultaneously.
Due to this characteristic, collisions can occur when two devices attempt to send data at the same time. It's important to note that hubs do not have the intelligence to filter traffic or connect different subnets; they simply repeat the electrical signal to all connected devices.
Hubs contrast with switches, which operate at full-duplex and can send and receive data simultaneously without collisions, thanks to their capability to direct traffic based on the address of the receiving device. Because hubs operate at half-duplex and retransmit signals to all connected devices, they are prone to network collisions which can reduce overall network efficiency.
