I’m currently in the process of getting my A+ cert. What’s the difference between ICS and an embedded system?

I love when reddit brings questions just for me 😉
“embedded” systems can be and device that is “embedded” into something to make it “smart”, a good example would be your basic thermostat, a microwave, a dishwasher.. theres code in there, it can run for decades without needing any management..
if you connect an “embedded” device to a network, now you have an “IoT” device, like any smart home assistant.
if you gather a few of those IoT devices together into a network where the work collectively manage some physical process (a system of systems), you have an industrial control system (ICS). ICS systems /tend/ to rely on “PLC”s (programmable logic controller) as their hands – IoT devices with relay outputs and sensor inputs – to take physical actions in the real world.
be careful using the terms “SCADA”, “ICS” and “DCS” interchangeably when working with control system engineers
good luck on your A+
