Which of the following statements about switches is true?

The statement about switches managing multiple data streams at once is true because switches operate at the Data Link Layer (Layer 2) of the OSI model, where they utilize MAC addresses to forward frames within a local area network (LAN). By maintaining a MAC address table, switches can efficiently direct incoming data packets to their specific destination ports based on the intended recipient's address. This capability allows them to handle multiple data streams simultaneously, improving the overall network performance and reducing collisions that occur in broadcast domains.

This characteristic of switches highlights their role in enhancing network efficiency by providing a dedicated communication path between source and destination devices, facilitating a smooth flow of data within the network.
