Does gigabit ethernet give you 1gb/s up AND down?

Been wondering this because I can't remember off the top of my head, and searching on Google doesn't help.

My instinct is not.

I do not feel obliged to believe that the same God who has endowed us with sense, reason and intellect has intended us to forgo their use, and by some other means to give us knowledge which we can attain by them. - Galileo Galilei

yes 

At least Google Fiber Does

and my sichool is 2 Gigabit up and down but thats commerical.

 

 

all the plans i have seen are gigabit up and down.

Yes it's symmetrical.

 

 

Edit:

Your Google-fu is lacking:

Gigabit Ethernet (Wikipedia)

 

Half-duplex gigabit links connected through hubs are allowed by the specification,[1] but the specification is not updated anymore and full-duplex usage with switches is used exclusively.

 

Full duplex is used for computers and routers as well. I don't even know if gigabit hubs exist. I've never seen a half-duplex gigabit connection.

So my desktop, with a gigabit lan port, can send 1gb/s at the same time it is receiving 1gb/s? Assuming no other bottlenecks.

Yes

go under device manager and see if it says Full or half Duplex 

what lan chip is just for verification?

gigabit fibre = 1Gb up and down

gigabit dsl (or adsl, can't remember) = around 1Gb down and 100Mbit up.

 

Assuming no bottleneck in your router, switch, PC and server you're connecting to: you will get 1Gigabit

they offer gigabit on DSL Damn

Do they run one cable or multiple cables?

Theoretically yes if your hardware on both ends supports full duplex which should let you send and receive at 1 gigabit speeds. I'm not totally sure but I believe regular gigabit ethernet cable can do full speeds both ways

Not sure if they do, but if they do the upload would be 1 tenth of the download speed

Intel i217

lol max TEMP on the chip is 85C

xD

IT looks like it should support 1 gb's up and down

 

 

just curious as would/will be  using 2 gb's worth of bandwith at a time xD?

uhm... he clearly ask about Ethernet

why bring up fiber or internet?

 

Full duplex connection will give you 1/1 performance in/out

 

the higher rate you receive obviously depends on storage capability, writing 125MB/s and Read at the same time with mechanical while possible but most likely will not get that max out, with SSD it's quite easy to max out 1gbps network.

 

but if this about getting 1gbps internet, then it all depends ISP network, and their reliability, also your networking setup for that matters.

You can always run a test as well, Hook 2 computers (dierctly/or switch/Router etc,) and transfer a file both way at the same time.

IPERF is a great little utility for measuring network speeds, both LAN & WAN. I'd be interested to know what you're thinking of doing with 1Gb up and down, if anything at all?

Usually yes with those plans. The term for upload and download being equal is symmetrical and is common in commercial and business internet.

haha :D Gigabit DSL :D That does not exist

 

Gigabit Ethernet is ususally Full-Duplex, which means that you can send and recieve data at 1 Gigabit at the same time (if your switch can handle it)

Down I can understand.

 

Up, I probably do not want to know.

Ethernet is pretty much always full-duplex (both up and down). Things like WiFi and powerline are not. But usually there'll be a bottleneck somewhere else, like a HDD on your NAS. Especially for Gigabit unless you have some sort of fantastic RAID setup or SSD cache.

 

And your internet connection has nothing to do with this so I don't know why people are talking about Google fibre

Fools think they know everything, experts know they know nothing
