Explain the benefits of full-duplex communication in networking.
Explain the benefits of full-duplex communication in networking.
Full-duplex communication increases bandwidth efficiency by allowing both ends of a connection to transmit and receive data simultaneously. This results in 100 percent efficiency in both directions, doubling the potential use of the stated bandwidth.
What is the difference between full-duplex and half-duplex communication?
What is the difference between full-duplex and half-duplex communication?
Full-duplex communication allows for bidirectional communication, while half-duplex communication is unidirectional, leading to potential performance issues and collisions.
How are switch ports configured for specific duplex and speed settings?
How are switch ports configured for specific duplex and speed settings?
Switch ports can be manually configured with specific duplex and speed settings using the respective interface configuration commands duplex and speed.

Study Notes
Configuring and Verifying Switch Ports
- 10/100/1000 ports operate in half- or full-duplex mode at 10/100 Mbps, and only in full-duplex mode at 1000 Mbps (1 Gbps)
- Autonegotiation is useful when speed and duplex settings of the connecting device are unknown or may change
- Manually set speed and duplex settings for known devices like servers, workstations, or network devices
- Duplex and speed settings should be checked when troubleshooting switch port issues
- Mismatched duplex mode and speed settings can cause connectivity issues
- Fiber-optic ports, such as 1000BASE-SX, operate only at one preset speed and are always full-duplex
- Auto-MDIX enables automatic detection of required cable connection type and configuration
- With auto-MDIX enabled, either type of cable can be used to connect to other devices
- Auto-MDIX feature is enabled by default on Catalyst 2960 and Catalyst 3560 switches
- The show running-config command can be used to verify the switch configuration
- The show interfaces command displays status and statistics information on network interfaces
- SSH client like PuTTY is used to connect to an SSH server such as switch S1 with enabled SSH and configured IPv4 address
