Hi everyone, I’m trying to understand our office network setup in China and felt a bit lost. What’s the distinction between routers and modems? Are they essentially the same device or are they different components combined in one unit? Also, back in Australia we used older routers that connected via a telephone port. Now we have one that looks similar to an Ethernet port but isn’t actually connected to the network—its other end connects to a NBN box in the garage, linked to a fiber optic cable. Can you clarify what that port is? Also, in our office we have three routers, and I noticed one on a shelf with an Ethernet port that connects to something else. On the right, there’s a compact unit with four Ethernet ports, a phone port, and fiber connections. I assume it’s similar to the NBN box but also functions as a router. When I tried connecting my laptop to one of those ports, nothing happened, so it doesn’t seem to be an Ethernet device. Could you explain what that part is? Thanks for your help! I’m a bit confused and appreciate the time you took to read this. The images aren’t loading properly, so I can’t share them.
Modems and routers serve different purposes. A modem handles the conversion of signals, such as analog phone lines or DSL, while a router directs data between devices, like connecting a PC to the internet. Modern devices often combine both functions into one unit, sometimes including additional security features like firewalls. These components may also act as PoE switches or firewalls instead of being routers alone.
