Networking help thread

[Sandvich]

I am pretty new to how internet and networking works, but I know quite a bit about hardware and troubleshooting. Can anyone please explain to me what all "this" is about?

[Kaede77]

Networking is a way for Computers to communicate with each other, sending or receiving data 

[flexin1981]

Man that is a very open question.

 

what is it that you want to know ?

Well I already know that

But more specific like this 10/100/1000 on network cards and how your pc connects to the internet and does 800mbps = 100Mbps

[flexin1981]

Hey, 

 

I am still a little unsure of the question and what you want to gain from this.

 

A network card is rated in bits per second and storage is in bytes. there are 8bits to every byte so you should be able to calculate from there.

 

100mbps =  12.5MBs

Oh okay so what about internet what is this 16 megabit average internet speed and if so whould you only be able to download stuff at 2 megabytes per second and what about the is 1000 megabit bandwith? do we really need 1000 megabit band with why not just 100 if the average download speed is 16mbps?

[Kaede77]

10/100/100 is the max speed of the network card eg 10 Megabits / second, Computers connect to a router that obtains a local IP address, then the router sends a request to get an Internet IP address. 800mbps does equal 100Mbps

So 10/100/1000 = to____________

[Kaede77]

1.25/ 12.5/ 125 Mbps

[Sandvich]

1.25/ 12.5/ 125 Mbps

 

And that means you can download stuff at 125Mbps?

[Kaede77]

It depends on your location, if you have copper wiring or fiber optic wiring, Your ISP, if your ISP throttles your download speed and if the card is 1000Mbps, then yeh you can run it at 125Mbps.

[Sandvich]

But I still don't get what 10/100/1000 it just seems like a bunch of random numbers.

[Sandvich]

1.) does all your computers connect to the router and then your router connects to the internet

 

2.) Is the download speed your computer or is it your router download speed?

 

3.) Why do people buy ethernet cards that are 1000mbps even if their connections are like 8mbps or 12mbps so can't they use the one intergrated in the mobo?

[Blade of Grass]

So 10/100/1000 = to____________

1.25MBps/12.5MBps/125MBps

 

1.25/ 12.5/ 125 Mbps

Keep in mind, Mb != MB

mb = Mb = Megabit

mB = MB = Megabyte

 

But I still don't get what 10/100/1000 it just seems like a bunch of random numbers.

10/100/1000 are the different speeds that the NIC (Network Interface Card) can connect at. These are the different speeds that follow the various standards (10Base-T/100Base-T/1000Base-T respectively).

 

1.) does all your computers connect to the router and then your router connects to the internet

 

2.) Is the download speed your computer or is it your router download speed?

 

3.) Why do people buy ethernet cards that are 1000mbps even if their connections are like 8mbps or 12mbps so can't they use the one intergrated in the mobo?

1) Yes, the router is the gateway device on the network, it's the bridge connecting your home network to the internet. For any computer to connect to the internet they must connect through the gateway (or router in this case).

 

2) The download speed is the maximum speed that your connection to the internet is. Usually devices that are wired to your modem (like a router) can achieve this maximum speed, but if you're connecting over a slower link (like WiFi) you may not get all of your speed.

Sadly, not ever ISP can/will actually give you all of the speed that you pay for, hence why it's the "maximum" speed.

 

3) A lot of people buy separate ethernet cards if they need more connectors or if the built in is not fast enough (in the case of an older motherboard). The speed of these cards also affect your speed on your local network (say, between a home server and desktop).

 

 

If anything I've explained is confusing I'd be more than happy to either go into more detail or explain it in a different way

Thanks for clearing that up, but what is the difference between a router and a modem.

Also what is this 802.11 thing?

802.11 is a series of wireless standards set out by the IEEE - Wikipedia
