I'm working on a project that will involve a few things communicating over Ethernet, and I'm wondering if I should be looking to buy a switch or a router.
The Ethernet stuff on the project includes:
- A PC
- An internet connection to the PC (I'm plugging into an already-existing network for this)
- Two programmable power supplies controlled by the PC via Ethernet
- Communication with another computer over Ethernet (no Internet involved)
The PC only has 2 Ethernet ports, so I'm wondering whether a switch or a router is what I need to expand that to the 4 that I will need.
