I am building my first pc and have a question.  Is there a certain part I need to buy so I can connect to my houses wifi or does it come with one of the parts of the computer?  i looked on the internet and i found some stuff about getting an ethernet card.  The help would really be appreciated

If you are building yourself then you need to buy a WiFi card. You can get one that goes in a PCI slot (or similer one on the motherboard) but id suggest picking up a USB card (there usually start pretty cheap like £10/$15) from any computer store or even some supermarkets now.

Edit: Ethernet is basically a wired network (for these purposes anyway) so an ethernet card would allow you to connect a cable to it and the other end to a router which leaves a wire trailing about. The WiFi card lets you do it wirelessly which is what you apparently want :) Either ask for a WiFi or Wireless USB card or something similer.

is there a difference between the to or are they essentially the same

Unless the motherboard itself has built-in WiFi (which is pretty rare) then you will need to find a USB WiFi dongle or PCI/PCI-Express WiFi card to add in.

Make sure the card is reviewed well (at least in like NewEgg user reviews), a shitty WiFi adapter, or at least terrible software for it, can be extremely frustrating.

EDIT: If you're asking about the difference between dongles and cards, they're functionally the same. USB is probably easier to deal with (and easier to dispose of if it's actually a piece of crap)

This look like a good usb card?

All that will do is give you more USB ports.

Wireless Network Adapters (USB and expansion slot)

thanks for the help

Also, you've gotta make sure you plug the electro-capacitator into the positron-flow-modulator so that your internets can download the hard drives.

what the fuck

These days I just use a laptop and plug in a external gpu unit like the vidock or the asus thing into a external monitor. Works enough to do a wild spectrum of stuff for me.

ok, thanks for clearing that up for me

No generally the only things that require direct power are Video Cards, The Motherboard itself, DVD Drives, Hard Drives. The USB version will just plug into a USB slot and pretty much work. May need to install drivers but thats it.
