Corrections/notes on the video
On the last 'slide', you write "always continues it's (sic) service" when you meant to write "its" instead. --81.17.28.58 (discuss) 19:32, 23 October 2013 (UTC)

LAN node distance is 500m at max
In this video you claim that the maximum distance in a LAN is 500 meters. Where do you take this information from? In earlier lessons, you talked about a theoretical maximum of 3000 meters (iirc). --103.16.26.171 (discuss) 19:34, 23 October 2013 (UTC)

Ethernet transfer distance
Is 500m is the maximum distance for ethernet? In last videos we saw examples where it was apprx. 1500m. --141.26.69.70 (discuss) 01:16, 3 November 2016 (UTC)

Subnet Mask
is subnet Mask different from network prifix? or are they related concepts at all? --141.26.69.70 (discuss) 18:43, 4 November 2016 (UTC)

Why are there no collision when data sent via routers?
You have explained in last videso that there is Ethernet algorithm in LAN by which computer avoid data collision. My Question is why not that collision could happen during transfering through Routers? There is also possibilty that two computers from different network want to send data through routers at the same time then there would be collision right? --91.67.36.129 (discuss) 16:57, 13 November 2020 (UTC)


 * Routers have a separate port for each interface. The router's processor is fast enough that it can keep up with incoming and outgoing data across all ports. So, even if two packets arrive at the same time, the buffer on the adapter will hold the data long enough for the processor to get to it before it is overwritten by the next incoming packet. The only time you have a collision is when you have two ports on the same physical medium transmitting at the same time. -- Dave Braunschweig (discuss • contribs) 17:56, 13 November 2020 (UTC)
