Devices attached to a switch can operate in ___ duplex mode.

Devices attached to a switch can operate in ___ duplex mode.

• A. half
• B. full
• C. simplex
• D. all

Answer: (B)

Devices connected to a switch can operate in full duplex mode because a switch allows for simultaneous transmission and reception of data between the devices connected to its ports. In full duplex, each device can send and receive data at the same time without collisions, which significantly enhances network efficiency and performance. This is different from half duplex, where devices can either send or receive data at any given moment but not both simultaneously, leading to potential delays and collisions. The choice of full duplex is particularly relevant in switched networks, where the switching technology ensures dedicated bandwidth to each device and manages data flow effectively. This capability makes switches preferable in modern networks, supporting higher data rates and improved communication between devices. While some network configurations might still use half duplex (especially in older systems or specific applications), full duplex is the standard mode for devices linked to a switch in contemporary networking environments.
