Gigabit ethernet allows for ethernet connections up to 1 gigabit (1024 megabits, thats the same as 512 Size M connections together).
(If the next bit is a bit confusing, see the Brief at the bottom).
Generally, a lot of computers are coming down in price, so I would get one. You would need extra hardware (unless you connect directly to the modem, in which case you just need a good cable and a good modem), but since Virgin don't yet sell anything faster than 20mbit (the other type of ethernet goes up to 100) you dont need to bother with that for now, but having the port is useful for future proofing.
If your getting a router, I would not bother for now. Wait till the final 802.11n routers come out, and get one with Gigabit(1000)/100/10 switching. You don't need an ADSL router. Also note to get 802.11n cards so you get the fastest speeds out of them.
For now however, Virgins 20mbit will work fine on whatever you use, so this is my advice in brief:
- Get a computer with a Gigabit port (as they should not be overly expensive)
- When getting a router, get one with Gigabit (1000)/100/10 switching, that has Wi-Fi type: 802.11n
- Make sure any wireless cards you get are also 802.11n. Don't buy any wireless till the n spec comes out in final.
- Your 20meg will work fine on whatever port.
- If Virgin bring out speeds faster than 100m, then either directly plug the modem into your gigabit port (using a certified gigabit cable, CAT-6), or plug it into the router that I mentioned earlier.
If your confused, just ask
