A colleague of mine said that there was something to buy that could be connected to make the whole laptop faster but he didn't know what it was called? Wanted to ask you if you know what?

No, it does not exist.
You can replace the processor (and with many laptops this is difficult or even impossible). But don't connect anything that magically improves performance
Well you can either install a better CPU or more ram
This works with GPUs over Thunderbolt, but not with CPUs.
You can only connect an e-GPU (if the appropriate connection is available). In my opinion, it is not worth it.
You can usually only upgrade the RAM and memory. Processor only works in the least cases.
