Which components have a unique ID?

Question

Iron

Good afternoon, what components have a unique identifier that can be obtained programmatically? Granted a ban on hardware, I'm not looking for ways to get around it on old hardware, I'm not going to spoof anything (only the MAC address, perhaps), but I would like to leave details that cannot be identified. As far as I know, RAM has unique identifiers, hard drives, oddly enough, a monitor. This is all I found in AIDA64. As far as I've heard, there is no way to get the processor's serial number programmatically (some kind of incident from Intel's Pentium 3 days), but what about the video card? Found Vendor Id, Device Id, but they are not unique. On motherboards, it seems that the serial number is not always indicated, so, in theory, it is unlikely that it is used for a ban, but there is a network card on the motherboard, maybe she has some kind of serial number? (MAC I would change) Any other components on the motherboard, power supply, sound card? There is also a router (D-Link DIR 300), the Internet goes through it, can it be tracked somehow? In general, if someone has thoughts on this matter, I will be glad to hear.

Answer 1

There are a lot of algorithms, and more often everyone saws something of their own.
From motherboards and vidyuhi you can get serial numbers, from other components some things inherent only to them.
For example, one of the options
and at the output you will get something like d41d8cd98f00b204e9800998ecf8427e , but more often they use something from the motherboard aka a rarely changing thing.

Answer 2

if the ban is on the network, then usually at the poppy address. this is the only unique identifier that you shine on the network.
in memory modules there is an SPD chip where there are memory parameters, including identifiers, but for example nonames do not bother with such a thing at all.

Answer 3

System Information Viewer :
video card: yes Board Serial
motherboard: yes Serial Number
, etc.
