Hello, i couldnt find anything similar on the first few pages of the forum so i want to ask:

I have the following set-up


where my Ethernet cards and my switch support 1Gbps data transfer but my router supports only 100Mbps. What's the transfer rate between my 2 PCs? Do i need a 1Gbps router to have a Gigabit network?

It should be around .5 Gbps.

umm okay, so you mean that my router being a 100Mbps one doesn't limit the transfer speed of my network, do i get that right?

The easiest analogy is thinking of each port as a water pipe that can move a fixed amount of water.

if you have a pipe from comp1 to switch1 that can move 1gbit and a pipe from comp2 to switch1 that can move 1gbit, then the max speed bwteen the two computers is 1gbit.

The pipe from switch1 to router1 is 100mbit, so the max speed of 100mbit to the router is split between the two computers. not to say you have 100mbit internet.

Network packets are fairly efficient and it's all about weakest links.
