Router Vs Switch?

post #1 of 12
Thread Starter 
For the past 10 years i have been using an 8-port 10/100 switch from 3COM. The Latest modem/Router i got also offers 10/100 ethernet ports (3 of them).

Since i only want to cennect 2 PC on the Router and also have a connection between them, shall i use the Router and cancel out the switch altogether?

Since ports are 10/100 on both of them, i only wonder if the switch offers better services somehow, or has some feature that will convince me to keep using it.

What;s your take on this, guys?
Router is SAGEM FAST 2404 and switch is 3Com office connect.

10 years old? Hey, maybe it's time to upgrade to Gigabit (if both PCs have it, if not, well, don't need it). If not, you don't need the switch for two PCs. Just have them plugged into the router.

Router vs Switch

a "Router" is a layer 3 Device.
-It joins and segregates networks and broadcast domains.
-It can understand network addresses and route based on that information.
-Its smarter than a switch or a hub, but it has a specific funtion
But what you have its both a router and a switch combined basically. (Your ISP Modem)

a Switch is a Layer 2 Device.
-It passes traffic along based purely on Physical address.
-It smarter than a Hub, but it only lives on Layer 2 of the OSI model.

The LAN ports on your SoHo ISP Router are Switch ports.

Just use those. Same performance.

*No need for a gig switch. Unless you transfer massive files from one pc to the next and have dedicated NIC cards and have configured jumbo packets you will not benefit from a gig switch as opposed to your 10/100 Switch ports on your router or switch.

Well Actually i intend to make a one time full transfer from the OLD PC to the new one (Approx 400GB transfer), and then have the OLD PC operate as some kind of TEST PC to evaluate small software and perform easy tasks. So ultimately i concur that gbit LAN is not needed for my use.

I was just wondering switch as a device offers more options like Half/Full duplex jumbo frames and or anything more that you cant get out of the switch ports. Since i'm a noob when pertaining to such matters i only know these features by name thus i need your help convincing me on how to act.

Router segregates broadcast domains
Switch segregates collision domains.

If you are using a consumer grade router, the LAN ports are in fact a switch.

The LAN ports on the modem/router Will have the same functionality and control as the Switch ports do. (Because they are switch ports) so you normally will be able to control speed/duplex (Half/Full) and MTU size.

Your mileage may vary though. It comes down to the functionality included with your router.

*For the sake of simplicity I would just take the HDD out of the old PC and then connect it to the new PC...Copy off what you need...then return it back to its original configuration. Instead of worrying about packet size and all that networking jazz.

This is coming from a network guy.

Yeah, like the others has said.. the extra ports in the router in consumer grade gear is 99% of the time just a switch. So you can use that without any performance penalties.

Ok guys i went ahead and connected both computers directly to the router, since there was no objection about the switch having any advantages. I just wanted to make sure, and i did. So thank you all guys for advising me. Take Care.

Oh man, its worse than i thought. I just tried now the first batch of transfers and i'm getting 2.5MB/s! It's like I'm downloading my files to the computer sitting next to me!

It will take 5+ hours for the first 40Gigs. It's ok though i'l; just have to be patient...

Why not hook the old drive to the new computer then put it back after transfer?
