PC hardware--CPU & Motherboard & RAM/Equipment to level spikes
I am attempting to do research into something that tends to run on computer monitors. There is a piece of equipment built into a monitor power cord the levels the spikes or variations in the electricity and I do not know what it is called.
Do you have any idea of the name or of anyone who might know?
Do you have a picture of what you're trying to locate?
Off-handedly it sounds like you're describing the snap-on ferrites that some display cables use, you can read about those on Wikipedia (the article does have pictures too): https://en.wikipedia.org/wiki/Ferrite_bead
They aren't what I'd call "equipment" in that they're entirely passive devices, and they don't serve to "level spikes or variations" - their purpose is to block (or reduce) high frequency noise.
From the "level spikes or variations" comment I'm more inclined towards a CVT or AVR device, but that won't be built into a cable - it will be a large stand-alone unit that provides cleaner electrical power for whatever is hooked into it (and they can get very expensive depending on capacity). You can read about those kinds of devices on Wikipedia too,
Common manufacturers of AVR/CVT devices include companies like TrippLite and APC. For example see here: http://www.tripplite.com/sku/LC1200
If none of this is related to the specific device you're after, please try explaining or describing the device again, and add pictures if at all possible.
