Will my laptop be more difficult if I download several files?

Thank you

A laptop can't be "difficult", that's a human trait.

Multiple concurrent downloads put a heavier load on the computer and the internet line, everything slows down altogether - nothing else.

As it was already written. Difficult can only be an "ex". Namely, when she learns that you have a "new" at the start. With your laptop, it's just that he'll cut you off as soon as you run too many processes.

If you mean "heavier": no.

This is all overshadowed by the fluctuations of the battery, because its mass should fluctuate at least a few picograms, if you load / unload.
