Wired or Wifi for Computer

Hey all. So when i used a desktop, obviously i use the laptop wired with ethernet cable. But i no longer use a desktop and thus use a laptop now. The thing is i connect it to external monitor almost always and thus use ethernet cable to use wired internet. Sometimes i use wifi if i bring laptop to somewhere else in apartment.


But if you are planning to use it connected and on a desk, you should always use it wired with an ethernet cable right? I recalled wired is always faster. The thing is i don't have an ethernet cable now and just using it on wifi and it seems okay. But you would always suggest get an ethernet cable for you are using it on a desk where you don't move it right?


Also i know this may sound like a dumb question. But could an ethernet cable carry a virus? Like imagine someone gives you an ethernet cable or you bought a used or or you bought a new one but it was actually returned and used. Is it possible for that to infect your laptop?

 

Im going to buy an ethernet cable at one of these stores like computer shops but i want to know, is it possible an ethernet cable has virus? I would be connecting it from modem to an ethernet adapter connected to a usb port on my laptop. I know this may sound very foolish to ask this but i want to make sure. I ask this because i cannot order an ethernet cable directly from say amazon because of where im located now.

 

No it cannot have a virus.

 

Thanks!
