What cat5 wires foir gigabit lan?

Can you just use normal cat5e wires for this? Also can you just connect a gigabit switch to a 10/100 router and all the computers to the switch so they can use gigabit?

Cat5e can handle 1GB speeds.

Connecting a GB switch to a 10/100 router will only give you gigabit on the switch, the packets over the router will be routed at 10/100.

Thats fine because all the computers will be connected to the switch, game consoles connected to the router.

On the switch it says because its full duplex you can get speeds of upto 2000mbps, whats that about?

I guess if your PC's NIC's can run at full duplex, you might get 2000mbps transfer rate.

It's because, being full duplex, you'll get 1000Mbps both ways.

So I can send a file to another computer at 1gbps and be recieving a file at 1gbps as well at the same time?

it means in theory computer a can send a file to computer b at 1gb speed while receiving a file from another computer on the network at 1gb speed (could be computer b, or even a different one e.g computer c).

It essentially means each port on the switch has a potential of 2gb bandwidth on it (1000 each way) so a 4 port switch would have a maximum theroetical speed of 4 x 2Gigabit if you had 4 pc's plugged in and transmitting.

In reality though you won't see those speeds for many reasons (overheads, switch not being powerful enough to pass all those packets through, disks on machines not being able to keep up, acknowledgement packets being transmitted, e.t.c)

Thanks that answered another question of mine as well.

I read that to get the true gigabit speeds of 125mbytes/s of 1000 megabits that it would be best to come from a mobo with a gigabit port on it.

gigabit PCI cards are going to be a speed increase over 10/100 cards, but just have that limiting factor of PCI bus speed.

I working on getting a gigabit setting up between two pcs and have a raid setup of 2xsataII drives, how could i test the speed (MB/s) over the network?
