Linking two computers to a router versus a switch
Linking two computers to a router versus a switch
This is a dumb question. I KNOW this is a dumb question. I know that the differences will be microscopic. I just want an understanding of what the difference will actually be, both technically and performance-wise. I'm likely about to move to a new apartment soon, and I'm planning out my network. I have two computers that will likely use a decent amount of bandwidth, and regularly will need to communicate with each other via the network. There's two possible layouts I'm considering (trust me that these are the only two that make sense): Router-> 2x 25ft ethernet -> two computers Router-> 1x 25ft ethernet -> 1 gigabit switch -> 2 computers The internet connection coming in + the router itself + the ports on the computers + the switch are all gigabit. While I don't know for sure what ethernet cable I have (5e, 6, 8, etc), I know for a fact that it can carry a gigabit signal as well. I'm aware that in 99% of cases, I won't notice a difference. Possibly including this one. And, again, I know this is a dumb question. But, basically: would there be any measurable/practical difference between snaking two ethernet cables around the apartment vs just one? Thank you all in advance.
The main issue arises when both devices require simultaneous internet access or if the router's performance is compromised. Bandwidth may be unevenly distributed, with roughly half going to each device through the limited gigabit connection to the switch. This isn't usually a significant problem because most setups don't rely on high-speed links for multiple peripherals.
Note: The router described likely functions as a unified device connecting multiple LAN ports to the internet via a single WAN link, with the AP handling local network traffic.
Are you concerned about the additional time signal takes to travel 25ft? That's almost nothing. Perfectly, there should be no switch because it adds another point of failure you don't need. It doesn't actually do anything your AllInOne router isn't already handling. You also need to power a backup device... But adding a switch lets you connect another one, like a NAS or laptop if needed. The decision really comes down to whether you want more switchports for future use.
I focused more on the 25-foot measurement than the actual length. The idea of using two devices on the same 25-foot segment seemed unnecessary compared to having two separate 25-foot connections. The short answer is "no real downside," which feels reassuring.
Both the router and the dedicated switch you’re considering cost 1 gigabit. The prices won’t vary.
I also had some confusion about this. I already have the switch. Understood—this was a big deal at a steep discount in the past, and it's just been gathering dust. Both designs would save me extra money. It was all about picking the best layout. Thanks for the input—it really helps!
It presumes a device like a phone or tablet can reach the PCs' content. If the PCs only have one gigabit connection to the router, they won't be able to handle the router's clients and will limit the gigabit speed.
There could be variations in how quickly data is processed. When both devices upload simultaneously, they might create a bottleneck, raising latency based on buffer size. Switches usually have minimal buffers, which could result in reduced latency compared to other setups. Ultimately, comparing both configurations may help determine the optimal choice for your needs.
