Question on Rj45

I might be able to get my dad to upgrade us to midcontinent's max internet, which has an unthrottled connection, and when I called them up to ask they claimed can go as fast as your NIC and hook ups can go.

So my question is how fast can an RJ45 Cat5 cable transfer? My brother told me 100Mbps, but I'm not too ready to believe him being he's usually just guessing on things trying to act smart.
 
Cat 5 will transfer data at 100Mbps. You would be very lucky to get an internet connection of the same speed! That would be immense!
 
Well midco claimed that unthrottled goes as fast as my computer allows, and I know my onboard NIC is 10/100/1000 so it's up to how fast my cable can go then.

Also, how much better is cat6? My friend said I should upgrade to that.
 
cat5e will go 155mbps if on applicable router/hub/switch it may also go to speeds up to 1gbps for a VERY short distance, i would get the cat6 cable so you would have unlimited**** network speed and internet, although I thought the fastest public internet server was 220mbps but it was a server for the pentagon, i think. but go with the cat6 and you wont need to upgrade fro a while.

"Cat 5 and Cat 5e UTP cables can support 10/100/1000 Mbps Ethernet. Although Cat 5 cable may support to some degree in Gigabit Ethernet (1000 Mbps), it performs below standard during high-data transfer scenarios, so I do not recommend you to use Cat 5 cable in Gigabit Ethernet, use Cat 5e instead (of course Cat 6 is the best)."
And Cat 6 of course can easily preform at 1000mbps nearly flawlessly.
 
But if we have only cat 5 running to our house would it make sense to get cat 6? Or has cat 6 been out for a while and there is a possibility they ran it here originally?
 
you are most probably running cat5. In most cases if you upgrade to cat6 you will have to buy new cables AND network adaptors for all of you computers / hardware.

You can tell whether you are running cat5 or cat6 by looking at the cable, it should have some writing on it, and mostly it will say something like "cat5 UTP"
 
If you have Cat5 running into your house and there's no way to replace it?

Then surely you would just be throwing money down the drain putting Cat6 on ANYTHING after that C5 cable. (Unless of course you want super fast LAN speeds lol)
 
Nevermind, I was having a stupid moment. I have cable internet and so I get my connection from the coaxial cable.

So my new question is how fast can coaxial transfer?

Also, I was told by a friend that I can use a cat6 cable with the same NIC cat5 uses.

Untrue it is either 10mb, 100mb or 1000mb .. there is no 155mb standard. If you have a router that you bought at a big box store, you wont get faster then 10mb. Most Linksys and similor routers have a 10mb wan port .. and are not powerful enough to go much above 10mb anyhow.

Untrue 100 meters is the max distance for 1GB, it uses 4 pairs to compensate for the higher speed (100mb uses 2 pairs)

Untrue, many places have faster internet connections. I have seen many 1GB internet connections. a OC 192 is 10gb, and a OC 768 is 40GB.

Cat 5e or 6 .. does not matter, both are rated for 1000mb. Though 10gb is planed, Unless you use shielded cables, 1000mb will be the max you can get.

I also dont think it was a "server" at the pentagon, perhaps you mean their network and that has long changed.

Google and youtube have many 1GB internet connections at their datacenters. I was at a google datacenter a few months ago, and they had a much faster connection.

There is no way they can afford to give you a 100/1000mb dedicated connection. Even FIOS is not dedicated, and dont support 1gb.

Cable speeds are generaly upto 16mb.

Depends, you have a cable modem?

Fastest i have seen is 16mb down and 2mb up.

I am sure it can do much faster (hell a T-3 is 45mb over two cable coax .. but is limited to 100m if i recall)
