Does a 10mbps nic effect speed of 100mbp

By jake4313 ·
I recently attended a prep class for the A+ Certification Exam for hardware/operating systems. During a brief discussion on networks, the instructor indicated that a 10/100mbps network can be slowed down by a workstation with a 10mbps nic while others are using 100 nics. Is this true? If so, why?

Does a 10mbps nic effect speed of 100mbp

A 10mbp NIC is not going to affect a 100mbp network. The 10mbp NIC will only connect to the network at 10mbps regardless of the speed of the rest of the network. It will only connect to the network if it is connected to a port that supports 10mbps. The network hardware should be able to able to handle the traffic flow. If the hardware (switch or hub) cannot handle the mixed speeds, then you may see some degradation, but the degradation will only indirectly be caused by the slower NIC.

Wehave +2000 workstations, +50 servers, +400 printers all running at various speeds and duplexes. We do not see any degradation in speed or efficiency.

So...my answer is a 10mbp NIC will not directly affect the overall speed of the network.

first sory for bad english

it's not true because any 10 Mbps NIC not possible direct to connect to any 100 Mbps network. Any 10/100 hub must have one internal switch 10/100

I both agree and respectfully disagree with the other answers. In a mixed 10/100 network a 10 mbps can only communicate at its highest rated speed. It doesn't slow down the whole network, it only communicates at a slower rate. Two 100 mbps machines will still communicate at the faster rate. A switch or hub or NIC that is required to auto-sense the different speeds will, of course, introduce some latency. But those things operate in milliseconds and the change is imperceptible to mere humans like us.
