Network switch

[Mascarad ninja]

Yesterday I watched a video of Liness about 100gig switch, and I did not understand a point, which is whether the switch needs internet with the same speed to connect divices or it only connects devices at that speed via lan

Yes, transferring files across the network is limited by the local network hardware.

 

The internet speed is limited by your ISP  for the most part, unless you pay for the top level service then it is the connection limit.

It doesn't need internet at all. It connects devices together.

A switch's main purpose is to switch packets locally, at very high speed. Yes you can get multi-layer switches that can do some (or even a good bit of) routing at those high speeds but the main purpose is to get the packets in and out and either to the end devices or higher up the chain to be moved to their final destination.

Does this mean that even if I have 1gig internet speed I can transfer data locally at 10gig if my switch supports it

Yes, provided one of two things:

You have everything on the same subnet/VLAN connected to that switch

-OR-

You have a switch that can do routing as well and has the SVIs (Layer 3 VLAN interfaces) configured on that same switch.

 

*Assuming the end devices are connected to 10Gbps capable ports and themselves are using 10Gbps interfaces too.

To further what @Luricksaid, your storage also needs to be up to the task.  If you are using harddrives, they can bottleneck the transfer depending on the set up.
