One port isn't an issue unless you are saturating that one line, also it is all going down to one line when it goes to the server. If you saturate more than the switch can store and forward it drops the frame. It would be odd if that was the case giving the small number of devices running on the network. I would check and make sure the switches connected to each other are both negotiating at the full speed of the switch e.g. gigabit if it is a gigabit switch.
Does the tablet freeze up as well when the other machines do? If so, i would look at the switch in the back as the issue or the line going to the server.
If it is just the front machines, it may be an issue with the line itself, or the first switch in the bar.
They're Plug and Play Gigabit Switches from Cisco on the front and a plug and play D-link gigabit switch in the back .
Tablet does not freeze up while the other terminals do from my understanding - but it's also routed from the firewall to the port that feeds into the switch..
Just replaced the first switch in the bar a week ago and it didn't help with the issue.
Can you attack network diagram? My brain is hurting today, I don't want to visualize this network in my head, I'd rather see how it looks.
Give me a few and I'll get one added to the thread.

this is the Diagram I came up with based on the equipment and the setup. Hopefully gives a rough understanding of what I'm saying -

So it's not a collision Domain because their Obsolete in wired networks due to switches -
I'm not sure what else could be causing the issue other than bad cabling/ Bad terminals/ Bad switches.
May be worth replacing the other bar switch and changing out the Cabling under the bar. -

May be worth replacing the other bar switch and changing out the Cabling under the bar.So start with the basics and see what you can track down. If you are getting congestion or bad switches / cabling, you'd expect to see it even with a ping. Ping from device to device and see if you ever get latency or drops. If not, likely it's not a networking thing.
Can you describe the freezing? Like if you do X which devices freeze. And if you do Y, these other devices freeze.

Only information I have is " when we're Busy, and we try to order items on the terminals they run slow and freeze up. then it comes back then it shows up. the delay is anywhere from 15 seconds to 2 minutes"
Nothing specific when it comes to what their doing on the terminals. -

Cause it's the exact same image/setup as the other site they have, and the other site doesn't run slow what so ever.

Only difference is, they have 2 less terminals at the other location ; same setup as this one *

Collision domains are super simple
Every port on a switch is it's own collision domain, which is why they are no longer relevant. The only time they are relevant is when you are using a hub (which you will never see).

Still, many times more likely to be a hard drive or something.

apparently, Our Des Moines Office did this setup , we did the other sites set up which would be inconsistent on our end. My boss is claiming that Their image was broken, and we fixed it in house before it went out to the site, which would mean, Scott, You're correct that it's a Server issue.
You know the saying to many hands in the cookie jar?
that's what seemed to happen here, so Now I gotta rethink this whole situation.FFS the more information I get the more I just want to just leave this place.
But I'm still learning and Can't say that I'm understanding.

@WrCombs said in Collision Domain - In POS:
They are having a huge issue when their busy, and all terminals are in use, where they will start to freeze for a few seconds, its only a problem when they are running more than one terminal on either side of the bar.
If their using 2 terminals on the same side of the bar it runs a little bit faster but there's still a delay.Is this really the issue or is this what you are being told? End users are wrong alot, and not always intentionally.
With how small that network is there is no way there is a bandwith issue from using POS terminals.
Also your diagram is probably inaccurate, I doubt they have 3 separate switches for 6 systems.

I want to explain why I thought this was the issue:
With using a single port on either switch, They would be on 1 collision domain - or so I thought.
That was stupid of me to think that, cause there's 2 ports make 2 different collision domains - and there's nowhere near enough Data to saturate those ports enough. -

no there are 3 separate switches.. One on either side of the bar, and one in the back office that feeds to the firewall and the sever.

Not ideal, but it should still work that way.
I think investigating at the OS level would be best. I doubt it doesnt only happen when its busy. Its only when they care or notice the delay.

I have to ask the dumb question. How are tablets being connected to a wired network?

This kind of just comes with experience. Can a network be the issue here? Sure, of course. But is it likely? Not at all. Both the "how could these machines overwhelm a network" aspect as well as the behaviour. It was acting like a congested server, not network. With experience you start to "feel" how the system is reacting and nothing really does that other than a combination of understanding as many of the components as possible, and just experiencing loads and loads of different conditions.

This feels crazy. So much to fail and so much hardware. All to save like... two wires?
